Description

本発明は、成膜装置、成膜方法および電子デバイスを製造する方法に関するものである。   The present invention relates to a film forming apparatus, a film forming method, and a method for manufacturing an electronic device.

最近、フラットパネル表示装置として有機EL表示装置が脚光を浴びている。有機EL表示装置は自発光ディスプレイであり、応答速度、視野角、薄型化などの特性が液晶パネルディスプレイより優れており、モニタ、テレビ、スマートフォンに代表される各種の携帯端末などで既存の液晶パネルディスプレイを速いスピードで代替している。また、自動車用ディスプレイ等にも、その応用分野を広げている。   Recently, an organic EL display device has been spotlighted as a flat panel display device. The organic EL display is a self-luminous display, and is superior in characteristics such as response speed, viewing angle, and thinness to the liquid crystal panel display, and is used in various types of mobile terminals such as monitors, televisions, and smartphones. The display is being replaced at a high speed. In addition, the field of application is expanding to displays for automobiles and the like.

有機EL表示装置の素子は、2つの向かい合う電極(カソード電極、アノード電極)の間に発光を起こす有機物層が形成された基本構造を持つ。有機ELディスプレイ素子の有機物層と金属電極層は、真空チャンバー内で蒸着材料が収容された蒸発源を加熱し、蒸着材料を蒸発させて、画素パターンが形成されたマスクを介して基板に成膜することで製造される。   The element of the organic EL display device has a basic structure in which an organic material layer that emits light is formed between two facing electrodes (a cathode electrode and an anode electrode). The organic material layer and the metal electrode layer of the organic EL display element are formed on a substrate through a mask on which a pixel pattern is formed by heating an evaporation source containing an evaporation material in a vacuum chamber to evaporate the evaporation material. It is manufactured by doing.

特に、金属電極層を基板に成膜するための蒸発源700は図7に示すように、複数のるつぼ710〜770が円周上に配置され、複数のるつぼ710〜770のうちで実際に成膜に使われるるつぼ710が蒸着位置に回転移動して基板に対して蒸着材料を蒸発させる。このような回転型の多点蒸発源をリボルバとも呼ぶ。一方、成膜対象の基板のサイズが大型化することにつれ、成膜速度などを高めるため、成膜装置内に複数の蒸発源を配置する必要が出てきている。   In particular, as shown in FIG. 7, a plurality of crucibles 710 to 770 are arranged on the circumference of an evaporation source 700 for forming a metal electrode layer on a substrate. The crucible 710 used for the film is rotated to the deposition position to evaporate the deposition material on the substrate. Such a rotary multi-point evaporation source is also called a revolver. On the other hand, as the size of a substrate on which a film is to be formed is increased, it is necessary to arrange a plurality of evaporation sources in a film forming apparatus in order to increase a film forming speed and the like.

ところが、このように複数の蒸発源を配置する場合には、蒸発源の配置によっては基板に対する各蒸発源の蒸発特性に差が生じ得る可能性があり、また、成膜装置の大型化につながる恐れもあるが、このような蒸発源の蒸発特性の差や、成膜装置内のスペース利用効率を十分に考慮して複数の蒸発源を効果的に配置する技術は提案されていなかった。   However, when a plurality of evaporation sources are arranged as described above, there is a possibility that a difference may occur in the evaporation characteristics of each evaporation source with respect to the substrate, depending on the arrangement of the evaporation sources, and also leads to an increase in the size of the film forming apparatus. Although there is a danger, no technique has been proposed for effectively arranging a plurality of evaporation sources in consideration of the difference in evaporation characteristics of the evaporation sources and the space utilization efficiency in the film forming apparatus.

本発明は、以上の点を考慮して、成膜装置内のスペース利用効率を高めて成膜装置の大型化を抑制できるように複数の蒸発源を効果的に配置した成膜装置、この成膜装置を用いた成膜方法および電子デバイスを製造する方法を提供することを目的とする。   In view of the above, the present invention provides a film forming apparatus in which a plurality of evaporation sources are effectively arranged so as to increase the space utilization efficiency in the film forming apparatus and to suppress an increase in the size of the film forming apparatus.

Another object is to provide a film forming method using an apparatus and a method for manufacturing an electronic device.

And a plurality of mask stock chambers 12 for storing masks before and after use, and a transfer chamber 13 disposed at the center thereof.

搬送室13内には、複数の成膜室11の間で基板10を搬送し、成膜室11とマスクストックチャンバー12との間でマスクを搬送する搬送ロボット14が設置される。搬送ロボット14は、例えば、多関節アームに、基板10を保持するロボットハンドが取り付けられた構造を有するロボットである。   In the transfer chamber 13, a transfer robot 14 that transfers the substrate 10 between the plurality of film formation chambers 11 and transfers a mask between the film formation chamber 11 and the mask stock chamber 12 is installed. The transfer robot 14 is, for example, a robot having a structure in which a robot hand holding the substrate 10 is attached to an articulated arm.

各成膜室11には、成膜装置(蒸着装置とも呼ぶ)が設置される。成膜装置では、蒸発源に収納された蒸着材料がヒータによって加熱されて蒸発し、マスクを介して基板10上に蒸着される。搬送ロボット14との基板10の受け渡し、基板10とマスクの相対位置の調整(アライメント)、マスク上への基板10の固定、成膜(蒸着)などの一連の成膜プロセスは、成膜装置によって自動的に行われる。   Each of the film forming chambers 11 is provided with a film forming device (also referred to as a vapor deposition device). In the film forming apparatus, the evaporation material accommodated in the evaporation source is heated and evaporated by the heater, and is evaporated on the substrate 10 via the mask.

The transfer robot 14 transfers the used mask from the film forming chamber 11 to the cassette of the mask stock chamber 12, and transfers a new mask stored in another cassette of the mask stock chamber 12 to the film forming chamber 11.

クラスタ装置1には、基板10の流れ方向において上流側からの基板10を当該クラスタ装置1に伝達するパス室15と、当該クラスタ装置1で成膜処理が完了した基板10を下流側の他のクラスタ装置1に伝えるためのバッファー室16が連結される。搬送室13の搬送ロボット14は、上流側のパス室15から基板10を受け取って、当該クラスタ装置1内の成膜室11の一つ(例えば、成膜室11a)に搬送する。また、搬送ロボット14は、当該クラスタ装置1での成膜処理が完了した基板10を複数の成膜室11の一つ(例えば、成膜室11b)から受け取って、下流側に連結されたバッファー室16に搬送する。   The cluster device 1 includes a pass chamber 15 for transmitting the substrate 10 from the upstream side in the flow direction of the substrate 10 to the cluster device 1 and a substrate 10 on which the film forming process is completed in the cluster device 1 is connected to another downstream side.

The transfer robot 14 in the transfer chamber 13 receives the substrate 10 from the upstream path chamber 15 and transfers the substrate 10 to one of the film formation chambers 11 (for example, the film formation chamber 11a) in the cluster apparatus 1. Further, the transfer robot 14 receives the substrate 10 on which the film forming process has been completed in the cluster apparatus 1 from one of the plurality of film forming chambers 11 (for example, the film forming chamber 11b), and connects the buffer 10 connected to the downstream side. It is transported to the chamber 16.

バッファー室16とパス室15との間には、基板の向きを変える旋回室17が設置される。これにより、上流側のクラスタ装置1と下流側のクラスタ装置1で基板10の向きが同一となり、基板処理が容易になる。   A swirling chamber 17 that changes the direction of the substrate is provided between the buffer chamber 16 and the pass chamber 15. Thereby, the direction of the substrate 10 becomes the same in the cluster device 1 on the upstream side and the cluster device 1 on the downstream side, and the substrate processing becomes easy.

成膜時には、基板保持ユニット21がマスク台22に対して相対的に下降し(或いはマスク台22が基板保持ユニット21に向かって上昇し)、基板保持ユニット21によって保持された基板10がマスク222上に置かれた後、真空チャンバー20の上部(外部)から導入された回転シャフト27によって、基板保持ユニット21及びマスク台22を回転させることで、マスク222及びマスク222の上に置かれた基板10を回転させる。これは基板10上に金属性蒸着材料が均一な厚さで成膜できるようにするためである。   At the time of film formation, the substrate holding unit 21 is lowered relative to the mask table 22 (or the mask table 22 is raised toward the substrate holding unit 21), and the substrate 10 held by the substrate holding unit 21 is moved to the mask 222. After being placed on the upper side (outside) of the vacuum chamber 20, the substrate holding unit 21 and the mask base 22 are rotated by the rotating shaft 27 introduced from the upper part (outside) of the vacuum chamber 20, so that the mask 222 and the substrate placed on the mask 222 are rotated. Rotate 10 This is to make it possible to form a metal deposition material on the substrate 10 with a uniform thickness.

図2には示していないが、真空チャンバー20の上面の外部(大気側)には、回転シャフト27を回転駆動するためのアクチュエータを含む駆動機構が設置される。また、マスク台22の下側には基板シャッタ(不図示)を設けることができる。基板シャッタは、基板10に対する成膜時以外においては基板10を覆っており、蒸発源23から蒸発された蒸着材料が基板10に堆積することを抑止する。   Although not shown in FIG. 2, a driving mechanism including an actuator for rotating and driving the rotating shaft 27 is provided outside (atmospheric side) of the upper surface of the vacuum chamber 20. Further, a substrate shutter (not shown) can be provided below the mask table 22. The substrate shutter covers the substrate 10 except when the film is formed on the substrate 10, and prevents the deposition material evaporated from the evaporation source 23 from depositing on the substrate 10.

真空チャンバー20の内部の下部には、基板10に成膜される蒸着材料が収納されるるつぼ231とるつぼ231を加熱するためのヒータ(不図示)とを含む蒸発源23、蒸発源シャッタ25、蒸発レートセンサー26などが設置される。   An evaporation source 23 including a crucible 231 in which a deposition material to be formed on the substrate 10 is stored and a heater (not shown) for heating the crucible 231, an evaporation source shutter 25, An evaporation rate sensor 26 and the like are provided.

金属性蒸着材料の成膜装置2の蒸発源23は真空チャンバーの底面に複数設置され、各蒸発源23は複数のるつぼ231を含む。各蒸発源23は回転駆動機構(不図示)によって回転することで、複数のるつぼ231の位置を順に移動させ、このるつぼの位置移動によってあらかじめ定められた蒸着位置に移動してきたるつぼから蒸着材料を順に蒸発させて基板10に堆積させる回転型の多点蒸発源(リボルバ)である。
各蒸発源23の詳細構造および複数の蒸発源23の配置構成については後述する。
A plurality of evaporation sources 23 of the metallic vapor deposition material film forming apparatus 2 are provided on the bottom surface of the vacuum chamber, and each evaporation source 23 includes a plurality of crucibles 231. Each of the evaporation sources 23 is rotated by a rotation driving mechanism (not shown) to sequentially move the positions of the plurality of crucibles 231, and the evaporation material is moved from a crucible that has been moved to a predetermined evaporation position by the movement of the crucibles. This is a rotary type multi-point evaporation source (revolver) that is sequentially evaporated and deposited on the substrate 10.
The detailed structure of each evaporation source 23 and the arrangement of the plurality of evaporation sources 23 will be described later.

基板10への蒸着材料の移動経路を遮蔽または開放を制御するために、蒸発源23の上部に蒸発源シャッタ25が設置されてもよい。これにより、蒸着位置のるつぼから蒸発した蒸着材料が基板10に堆積することが、必要に応じて(例えば、成膜開始前の準備工程など)一時的に抑止される。蒸発源シャッタ25が回転移動して蒸着位置のるつぼの上方を開放することにより、蒸着位置のるつぼからの蒸着材料が基板10に向かって飛散し、基板10への成膜が開始される。
蒸発レートセンサー26は蒸発源23のるつぼ231から蒸着材料が蒸発されるレートをモニタリングする装置である。蒸発レートセンサー26の配置位置の詳細については後述する。
An evaporation source shutter 25 may be provided above the evaporation source 23 in order to block or open the movement path of the evaporation material to the substrate 10. As a result, deposition of the evaporation material evaporated from the crucible at the evaporation position on the substrate 10 is temporarily suppressed as necessary (for example, a preparation step before the start of film formation). When the evaporation source shutter 25 rotates and opens the upper part of the crucible at the vapor deposition position, the vapor deposition material from the crucible at the vapor deposition position scatters toward the substrate 10 and film formation on the substrate 10 is started.
The evaporation rate sensor 26 is a device that monitors the rate at which the evaporation material is evaporated from the crucible 231 of the evaporation source 23. Details of the position of the evaporation rate sensor 26 will be described later.

<蒸発源の配置>
図3を参照して、本発明の実施例による回転型の多点蒸発源(リボルバ)の構造および複数の蒸発源の配置構成について説明する。
図3は、成膜装置2内での基板10と複数の蒸発源23との配置関係を説明するための上面図である。
<Arrangement of evaporation source>
With reference to FIG. 3, the structure of a rotary type multi-point evaporation source (revolver) and the arrangement of a plurality of evaporation sources according to an embodiment of the present invention will be described.
FIG. 3 is a top view for explaining the positional relationship between the substrate 10 and the plurality of evaporation sources 23 in the film forming apparatus 2.

前述のように、成膜装置2の真空チャンバー内の上部には、成膜時、回転シャフト27によって駆動されて回転する基板10が配置される。成膜装置2の真空チャンバー内の下部には、基板10と対向して、基板10の成膜面と対向する面内に複数(3個以上)の蒸発源23が配置される。本実施例では、成膜装置2の上面から見たとき(平面視で)、多角形の成膜装置2の各コーナー部に対応して四つの蒸発源23が矩形状D1の四つの角部に対応する位置に配置されている。   As described above, the substrate 10 that is driven by the rotating shaft 27 and rotates at the time of film formation is disposed in the upper portion of the vacuum chamber of the film formation apparatus 2. A plurality (three or more) of evaporation sources 23 are arranged in the lower part of the vacuum chamber of the film forming apparatus 2 so as to face the substrate 10 and to face the film forming surface of the substrate 10. In the present embodiment, when viewed from the upper surface of the film forming apparatus 2 (in plan view), four evaporation sources 23 correspond to four corners of the rectangular shape D1 corresponding to each corner of the polygonal film forming apparatus 2. Are arranged at the positions corresponding to.

各蒸発源23は、上述のように、成膜時回転(自転)によって複数のるつぼ231の位置を順に移動させて、るつぼごとに蒸着材料を蒸発させる回転型の多点蒸発源(リボルバ
)であり、それぞれの回転軸を中心に放射状に配置された複数のるつぼ231を有している。一方、四つの各蒸発源23は、図示のように、隣接する蒸発源23が互いに反対方向に回転(自転)し、それぞれのるつぼを順次移動させて成膜を行う。各蒸発源23の回転方向は特にこれに限定されない。
As described above, each evaporation source 23 is a rotary multi-point evaporation source (revolver) that moves the positions of the plurality of crucibles 231 sequentially by rotation (rotation) during film formation and evaporates the evaporation material for each crucible. And has a plurality of crucibles 231 radially arranged about the respective rotation axes. On the other hand, as shown in the drawing, the four evaporation sources 23 rotate (rotate) in the directions opposite to each other, and sequentially move each crucible to form a film. The rotation direction of each evaporation source 23 is not particularly limited to this.

各蒸発源23に設置されるるつぼ231の数は特に制限されず、各蒸発源23のるつぼの数は同じであってもよいし、異なってもよい。本実施例では、各蒸発源23が七つのるつぼ231を有する例を示している。   The number of crucibles 231 provided in each evaporation source 23 is not particularly limited, and the number of crucibles in each evaporation source 23 may be the same or different. In this embodiment, an example in which each evaporation source 23 has seven crucibles 231 is shown.

各蒸発源23において七つのるつぼ231のうちの一つのるつぼ232は、成膜時、蒸着位置に位置する。蒸着位置とは、該位置に位置するるつぼが基板10に向かって蒸着材料を蒸発させて供給する位置をいう。つまり、各蒸発源23は、成膜時、蒸着位置に位置するるつぼ232(以下、「蒸着用るつぼ」ともいう)をヒータによって高温(例えば、1300℃)に加熱して該当るつぼ232内に収納された蒸着材料を蒸発させて基板10に堆積させる。   One crucible 232 of the seven crucibles 231 in each evaporation source 23 is located at a deposition position during film formation. The deposition position refers to a position where the crucible located at the position evaporates and supplies the deposition material toward the substrate 10. That is, each evaporation source 23 heats a crucible 232 (hereinafter also referred to as a “deposition crucible”) located at a deposition position to a high temperature (for example, 1300 ° C.) by a heater during film formation and stores the crucible 232 in the corresponding crucible 232. The deposited material is evaporated and deposited on the substrate 10.

蒸着位置のるつぼ232内の蒸着材料が消耗すれば、蒸発源23を回転駆動して、蒸着位置に位置するるつぼ232を蒸着後位置に移動させ、予備加熱位置に位置するるつぼ233を蒸着位置232に回転移動させる。   When the evaporation material in the crucible 232 at the deposition position is consumed, the evaporation source 23 is driven to rotate, the crucible 232 located at the deposition position is moved to the post-deposition position, and the crucible 233 located at the preheating position is moved to the deposition position 232. To rotate.

予備加熱位置は次回(例えば、蒸着位置のるつぼ232内の蒸着材料が消耗したとき)において蒸着位置に移動するるつぼを予熱しておく位置である。以下、予備加熱位置に位置するるつぼ233を「予備加熱用るつぼ」とも称する。このように、次回において蒸着位置に移動するるつぼ233をあらかじめ加熱しておくことで、予備加熱位置に位置するるつぼ233が蒸着位置に移動した後に当該るつぼを加熱するのにかかる時間を減らすことができ、成膜時間を短縮することができる。   The preheating position is a position where the crucible that moves to the deposition position is preheated next time (for example, when the deposition material in the crucible 232 at the deposition position is exhausted). Hereinafter, the crucible 233 located at the preheating position is also referred to as “preheating crucible”. As described above, by preheating the crucible 233 that moves to the deposition position at the next time, it is possible to reduce the time required to heat the crucible after the crucible 233 located at the preheating position moves to the deposition position. It is possible to shorten the film formation time.

蒸着位置と予備加熱位置は、当該位置に配置されたるつぼが互いに熱干渉による影響を受けないように離間している。本実施例では蒸着用るつぼ232と予備加熱用るつぼ233との間に他のるつぼを配置している。   The deposition position and the pre-heating position are separated so that the crucibles located at that position are not affected by thermal interference with each other. In this embodiment, another crucible is arranged between the crucible 232 for vapor deposition and the crucible 233 for preheating.

各蒸発源23のすべてのるつぼ231の蒸着材料が消耗するまで蒸発源23を回転させながら蒸着を行い、すべての蒸着材料が消耗すれば、成膜装置2の動作を止めて、るつぼ231内に蒸着材料を充填する。   The evaporation is performed while rotating the evaporation source 23 until the evaporation material in all the crucibles 231 of each evaporation source 23 is exhausted. When all the evaporation material is exhausted, the operation of the film forming apparatus 2 is stopped, and the crucible 231 is placed in the crucible 231. Fill the deposition material.

以下、蒸発源23を成膜装置2内に複数配置する構造について詳しく説明する。
図3に示すように、複数(本実施例では4個)の蒸発源23は、そのうちの任意の3つの蒸発源23のそれぞれの回転中心が同一直線上に位置しないように配置される。言い換えれば、任意に選択される3つの蒸発源23の各回転中心軸間の距離をa、b、cとすると、a+b>cの関係を満たすように(すなわち、三角形状を成すように)、複数の蒸発源23が配置される。より具体的には、複数の蒸発源23は、各蒸発源23の回転中心が蒸発源23の配置面内における基板10の回転中心軸Oを中心とする一つの同心円C1上に位置するように配置される。
Hereinafter, a structure in which a plurality of evaporation sources 23 are arranged in the film forming apparatus 2 will be described in detail.
As shown in FIG. 3, a plurality of (four in this embodiment) evaporation sources 23 are arranged such that the respective rotation centers of any three of the evaporation sources 23 are not located on the same straight line. In other words, assuming that the distances between the respective rotation center axes of the three evaporation sources 23 arbitrarily selected are a, b, and c, a relationship of a + b> c is satisfied (that is, a triangular shape is satisfied). A plurality of evaporation sources 23 are arranged. More specifically, the plurality of evaporation sources 23 are arranged such that the rotation center of each evaporation source 23 is located on one concentric circle C <b> 1 about the rotation center axis O of the substrate 10 in the plane where the evaporation sources 23 are arranged. Be placed.

よって、複数配置される蒸発源23においてどの3つの蒸発源23も一直線上には位置していないので、蒸発源23間の距離を増加させずに成膜装置2内に複数の蒸発源23を効果的に配置することができ、成膜装置2内のスペース利用効率を高めることができる。   Therefore, since none of the three evaporation sources 23 are located on a straight line in the plurality of evaporation sources 23, the plurality of evaporation sources 23 are not disposed in the film forming apparatus 2 without increasing the distance between the evaporation sources 23. The arrangement can be performed effectively, and the space utilization efficiency in the film forming apparatus 2 can be increased.

また、このような複数の蒸発源23の配置の下で、各蒸発源23の蒸着用るつぼ232は、上記蒸発源23の回転中心を結ぶ円C1よりも内側に配置される。より具体的には、
各蒸発源23の蒸着用るつぼ232は、上記蒸発源23の回転中心を結ぶ円C1よりも内側に、かつ、基板10の回転中心軸Oからの距離が実質的に同一の同心円C2上に位置するように配置される。
このように、複数の蒸発源23において、成膜時に蒸着材料を実際に供給する各蒸着用るつぼ232が基板10に対して実質的に同一距離に位置することによって、蒸発源23間の蒸発特性の差を抑制することができる。
Further, under such an arrangement of the plurality of evaporation sources 23, the evaporation crucible 232 of each evaporation source 23 is arranged inside a circle C1 connecting the rotation centers of the evaporation sources 23. More specifically,
The evaporation crucible 232 of each evaporation source 23 is located on the inner side of the circle C1 connecting the rotation centers of the evaporation sources 23 and on the concentric circle C2 whose distance from the rotation center axis O of the substrate 10 is substantially the same. It is arranged to be.
As described above, in the plurality of evaporation sources 23, the evaporation crucibles 232 that actually supply the evaporation material at the time of film formation are located at substantially the same distance from the substrate 10, so that the evaporation characteristics between the evaporation sources 23 are reduced. Can be suppressed.

また、前述のような複数の蒸発源23の配置の下で、各蒸発源23の予備加熱用るつぼ233は、上記蒸発源23の回転中心を結ぶ円C1よりも外側に配置される。つまり、基板10の中心から近い距離に蒸着用るつぼ232が位置し、より遠い距離に予備加熱用るつぼ233が位置するように、各蒸発源23内における複数のるつぼ231の配置関係が構成されている。図4は、このような各蒸発源23における蒸着用るつぼ232と予備加熱用るつぼ233の基板10に対する相対的な配置関係を模式的に示した断面図である。より具体的には、蒸発源23のそれぞれの予備加熱用るつぼ233は、基板10の回転半径よりも外側に位置するように配置される。すなわち、いずれの蒸発源23の予備加熱用るつぼ233も基板10と重ならない位置に配置されている。   Further, under the arrangement of the plurality of evaporation sources 23 as described above, the preheating crucible 233 of each evaporation source 23 is arranged outside the circle C1 connecting the rotation centers of the evaporation sources 23. That is, the arrangement relationship of the plurality of crucibles 231 in each evaporation source 23 is configured such that the evaporation crucible 232 is located at a distance closer to the center of the substrate 10 and the preheating crucible 233 is located at a farther distance. I have. FIG. 4 is a cross-sectional view schematically showing the relative arrangement of the evaporation crucible 232 and the preheating crucible 233 in the respective evaporation sources 23 with respect to the substrate 10. More specifically, each preheating crucible 233 of the evaporation source 23 is disposed so as to be located outside the radius of rotation of the substrate 10. That is, the preheating crucibles 233 of any of the evaporation sources 23 are arranged at positions not overlapping the substrate 10.

予備加熱用るつぼ233は、成膜時に実質的な蒸着には関与しないが、予熱に必要な程度の高い温度で維持されるため、るつぼから輻射される熱が基板10に影響を及ぼす可能性がある。基板10の下部に複数の蒸発源23が配置される場合は、各蒸発源23において予備加熱用るつぼ233から輻射される熱が基板10に及ぼす影響の大きさに差がある可能性もある。
本発明の実施例では、各蒸発源23において、成膜時に実質的な蒸着に関与しない予備加熱用るつぼ233を基板10の回転半径より外側に位置するように配置することによって、各蒸発源23からの熱輻射の変動が基板10に及ぼす影響を低減することができる。
The preheating crucible 233 does not substantially participate in deposition during film formation, but is maintained at a high temperature necessary for preheating, so that heat radiated from the crucible may affect the substrate 10. is there. When a plurality of evaporation sources 23 are arranged below the substrate 10, there is a possibility that the heat radiated from the preheating crucible 233 in each of the evaporation sources 23 has a different effect on the substrate 10.
In the embodiment of the present invention, in each of the evaporation sources 23, the preheating crucible 233 which does not substantially participate in the vapor deposition at the time of film formation is arranged so as to be located outside the rotation radius of the substrate 10. The effect of fluctuations in heat radiation from the substrate on the substrate 10 can be reduced.

図2を参照して前述したように、基板10の成膜面と複数の蒸発源23との間の領域には各蒸発源23の蒸着用るつぼ232から蒸発される蒸着材料のレートをモニタリングするための蒸発レートセンサー26を設置することができる。この蒸発レートセンサー26は、成膜時に基板10への成膜に影響を及ぼさないようにするため、蒸発源23の上方において蒸発源23の回転中心を結ぶ円C1より外側の位置に設置することが好ましい。   As described above with reference to FIG. 2, in the region between the film formation surface of the substrate 10 and the plurality of evaporation sources 23, the rate of the evaporation material evaporated from the evaporation crucible 232 of each evaporation source 23 is monitored. Rate sensor 26 can be installed. The evaporation rate sensor 26 should be installed above the evaporation source 23 and outside the circle C1 connecting the rotation center of the evaporation source 23 so as not to affect the film formation on the substrate 10 during the film formation. Is preferred.

以上のように、本実施例によると、成膜装置内のスペース利用効率を高めて装置の大型化を抑制することができ、基板10に対する良好な成膜および各蒸発源23からの熱輻射の変動が基板10に及ぼす影響を低減することができる。   As described above, according to the present embodiment, it is possible to increase the space utilization efficiency in the film forming apparatus and suppress an increase in the size of the apparatus, to form a good film on the substrate 10 and to reduce the heat radiation from each evaporation source 23. The effect of the variation on the substrate 10 can be reduced.

図5は、本発明の他の実施例による回転型の多点蒸発源(リボルバ)の配置構成を示す。
本実施例は、上記実施例の構成に加え、少ない数のるつぼ241を有する小径の蒸発源24を追加で配置した構成である。蒸発源24は、蒸発源23よりも直径が小さい。具体的には、図5に示すように、回転軸(自転軸)を中心に五つのるつぼ241が放射状に配置された小径の蒸発源24を、隣接する二つの大径の蒸発源23の間に配置している。
FIG. 5 shows an arrangement of a rotary multi-point evaporation source (revolver) according to another embodiment of the present invention.
This embodiment has a configuration in which a small-diameter evaporation source 24 having a small number of crucibles 241 is additionally provided in addition to the configuration of the above-described embodiment. The evaporation source 24 has a smaller diameter than the evaporation source 23. Specifically, as shown in FIG. 5, a small-diameter evaporation source 24 in which five crucibles 241 are radially arranged around a rotation axis (rotation axis) is placed between two adjacent large-diameter evaporation sources 23. Has been placed.

蒸着材料の種類や蒸発量などの制御のために、必要に応じて、るつぼの数が異なる大径の蒸発源23と小径の蒸発源24を一緒に成膜装置2内に配置する場合がある。
本実施例は、この場合でも、前述の実施例と同様に、成膜装置内のスペース利用効率を高めるとともに良好な成膜および各蒸発源からの熱輻射の変動の抑制を可能にする蒸発源の配置構成を提案する。
In order to control the type of the evaporation material, the amount of evaporation, and the like, a large-diameter evaporation source 23 and a small-diameter evaporation source 24 having different numbers of crucibles may be arranged together in the film forming apparatus 2 as necessary. .
In this case as well, in this case, as in the above-described embodiment, the evaporation source that increases the space utilization efficiency in the film forming apparatus and enables good film formation and suppression of fluctuations in heat radiation from each evaporation source Is proposed.

具体的には、大径の蒸発源23(以下、「第1蒸発源」という)は、前述の実施例と同
様に、多角形の成膜装置2の各コーナー部に対応して四つの蒸発源23の回転中心が基板10の回転中心軸Oを中心とする一つの同心円C1上に位置するように矩形状の四つの角部に対応する位置に配置される。図5に示すように、第1蒸発源23の各蒸着用るつぼ232が長方形状D2の四つの角部に対応する位置に配置される。また、図5に示すように、蒸発源24が、隣接する2つの第1蒸発源23の間であって、かつ、長方形状D2の長辺に沿って配置される。
Specifically, the large-diameter evaporation source 23 (hereinafter, referred to as a “first evaporation source”) has four evaporation sources corresponding to each corner of the polygonal film forming apparatus 2 as in the above-described embodiment. The source 23 is arranged at a position corresponding to the four corners of the rectangle so that the rotation center of the source 23 is located on one concentric circle C <b> 1 about the rotation center axis O of the substrate 10. As shown in FIG. 5, each evaporation crucible 232 of the first evaporation source 23 is arranged at a position corresponding to four corners of the rectangular shape D2. Further, as shown in FIG. 5, the evaporation source 24 is disposed between two adjacent first evaporation sources 23 and along the long side of the rectangular shape D2.

また、各第1蒸発源23において、蒸着用るつぼ232は、第1蒸発源23の回転中心を結ぶ円C1よりも内側に、かつ、基板10の回転中心軸Oからの距離が実質的に同一の円C2上に位置するように配置される。図5に示す例では、また、各第1蒸発源23において、予備加熱用るつぼ233は、蒸発源23の回転中心を結ぶ円C1よりも外側に、より具体的には基板10の回転半径の外側に位置するように配置される。   In each of the first evaporation sources 23, the evaporation crucible 232 is substantially the same distance from the rotation center axis O of the substrate 10 inside the circle C <b> 1 connecting the rotation centers of the first evaporation sources 23. Are arranged so as to be located on the circle C2. In the example shown in FIG. 5, in each first evaporation source 23, the preheating crucible 233 is located outside the circle C <b> 1 connecting the rotation centers of the evaporation sources 23, more specifically, the rotation radius of the substrate 10. It is arranged so that it may be located outside.

小径の蒸発源24(以下、「第2蒸発源」という)は、隣接する2つの第1蒸発源23の間、具体的には第2蒸発源24の回転中心が隣接する2つの第1蒸発源23の回転中心を結ぶ線分Lと同一直線上に位置しないように配置される。より具体的には、第2蒸発源24は、その回転中心が基板10の回転中心軸Oを基準に線分Lよりも外側、かつ、円C1よりも内側に位置するように配置される。   The small-diameter evaporation source 24 (hereinafter, referred to as “second evaporation source”) is provided between two adjacent first evaporation sources 23, specifically, two first evaporation sources whose rotation centers are adjacent to each other. The source 23 is arranged so as not to be located on the same straight line as the line segment L connecting the rotation center of the source 23. More specifically, the second evaporation source 24 is arranged such that its rotation center is located outside the line segment L and inside the circle C1 with respect to the rotation center axis O of the substrate 10.

よって、第2蒸発源24を挟んで隣接する二つの第1蒸発源23間の間隔を狭く設定することができ、また、追加で配置される第2蒸発源24をできるだけ成膜装置2の内側に位置させることができるので、成膜装置2内部の空間利用効率を一層高めることができる。なお、図5に示すように、第2蒸発源24が有する複数のるつぼ241の数は、第1蒸発源23が有する複数のるつぼ231の数よりも少ない。   Therefore, the distance between the two first evaporation sources 23 adjacent to each other with the second evaporation source 24 interposed therebetween can be set to be small, and the additionally disposed second evaporation source 24 can be located inside the film forming apparatus 2 as much as possible. Therefore, the space utilization efficiency inside the film forming apparatus 2 can be further enhanced. In addition, as shown in FIG. 5, the number of the plurality of crucibles 241 included in the second evaporation source 24 is smaller than the number of the plurality of crucibles 231 included in the first evaporation source 23.

また、第2蒸発源24における蒸着用るつぼ242と予備加熱用るつぼ243は、第1蒸発源23のそれと同様に配置することができる。
つまり、第2蒸発源24において、蒸着用るつぼ242は予備加熱用るつぼ243よりも基板10の回転中心軸Oから近い位置に配置される。具体的には、蒸着用るつぼ242は第2蒸発源24の回転中心よりも内側に配置され、予備加熱用るつぼ243は第2蒸発源24の回転中心よりも外側に配置される。
Further, the evaporation crucible 242 and the preheating crucible 243 in the second evaporation source 24 can be arranged in the same manner as in the first evaporation source 23.
That is, in the second evaporation source 24, the crucible 242 for vapor deposition is arranged at a position closer to the rotation center axis O of the substrate 10 than the crucible 243 for preheating. Specifically, the evaporation crucible 242 is arranged inside the rotation center of the second evaporation source 24, and the preheating crucible 243 is arranged outside the rotation center of the second evaporation source 24.

更に、第2蒸発源24をできるだけ成膜装置2の内側に位置させることにおいては、このような第2蒸発源24の蒸着用るつぼ242と予備加熱用るつぼ243の配置条件および隣接する第1蒸発源23との配置関係も考慮し、次のように配置する。
つまり、第2蒸発源24は、その蒸着用るつぼ242が、基板10の回転中心軸Oからの距離が第1蒸発源23の各蒸着用るつぼ232と同一距離に位置するように(円C2上に位置するように)し、それと共に、その予備加熱用るつぼ243は、第1蒸発源23の各予備加熱用るつぼ233と同様に基板10の回転半径よりも外側に位置するように配置することが好ましい。
これによって、成膜装置内のスペース利用効率を高めながらも、良好な成膜および蒸発源(特に、予備加熱用るつぼ)からの熱輻射の変動による基板10への影響を低減することができる。
Further, when the second evaporation source 24 is located as far as possible inside the film forming apparatus 2, the arrangement condition of the evaporation crucible 242 and the preheating crucible 243 of the second evaporation source 24 and the adjacent first evaporation In consideration of the arrangement relationship with the source 23, the arrangement is made as follows.
In other words, the second evaporation source 24 is positioned such that the evaporation crucible 242 is positioned at the same distance from the rotation center axis O of the substrate 10 as each of the evaporation crucibles 232 of the first evaporation source 23 (on the circle C2).

<電子デバイスの製造方法>
次に、前述した実施例に係る成膜装置を用いた電子デバイスの製造方法の一例を説明する。以下、電子デバイスの例として有機EL表示装置の構成及び製造方法を例示する。
<Electronic device manufacturing method>
Next, an example of a method for manufacturing an electronic device using the film forming apparatus according to the above-described embodiment will be described. Hereinafter, a configuration and a manufacturing method of an organic EL display device will be described as an example of an electronic device.

まず、製造する有機EL表示装置について説明する。図6(a)は有機EL表示装置50の全体図、図6(b)は1画素の断面構造を示している。   First, an organic EL display device to be manufactured will be described. FIG. 6A is an overall view of the organic EL display device 50, and FIG. 6B shows a cross-sectional structure of one pixel.

図6(a)に示すように、有機EL表示装置50の表示領域51には、発光素子を複数備える画素52がマトリクス状に複数配置されている。詳細は後で説明するが、発光素子のそれぞれは、一対の電極に挟まれた有機層を備えた構造を有している。なお、ここでいう画素とは、表示領域51において所望の色の表示を可能とする最小単位を指している。本実施例にかかる有機EL表示装置50の場合、互いに異なる発光を示す第1発光素子52R、第2発光素子52G、第3発光素子52Bの組合せにより画素52が構成されている。画素52は、赤色発光素子と緑色発光素子と青色発光素子の組合せで構成されることが多いが、黄色発光素子とシアン発光素子と白色発光素子の組み合わせでもよく、少なくとも1色以上であれば特に制限されるものではない。   As shown in FIG. 6A, in a display area 51 of the organic EL display device 50, a plurality of pixels 52 each having a plurality of light emitting elements are arranged in a matrix. Although details will be described later, each of the light-emitting elements has a structure including an organic layer sandwiched between a pair of electrodes. Here, the pixel refers to a minimum unit that enables display of a desired color in the display area 51. In the case of the organic EL display device 50 according to the present embodiment, the pixel 52 is configured by a combination of the first light emitting element 52R, the second light emitting element 52G, and the third light emitting element 52B that emit light different from each other. The pixel 52 is often formed of a combination of a red light emitting element, a green light emitting element, and a blue light emitting element, but may be a combination of a yellow light emitting element, a cyan light emitting element, and a white light emitting element. There is no restriction.

図6(b)は、図6(a)のA−B線における部分断面模式図である。画素52は、基板53上に、第1電極(陽極)54と、正孔輸送層55と、発光層56R、56G、56Bのいずれかと、電子輸送層57と、第2電極(陰極)58と、を備える有機EL素子を有している。これらのうち、正孔輸送層55、発光層56R、56G、56B、電子輸送層57が有機層に相当する。また、本実施形態では、発光層56Rは赤色を発する有機EL層、発光層56Gは緑色を発する有機EL層、発光層56Bは青色を発する有機EL層である。発光層56R、56G、56Bは、それぞれ赤色、緑色、青色を発する発光素子(有機EL素子と記述する場合もある)に対応するパターンに形成されている。また、第1電極54は、発光素子ごとに分離して形成されている。正孔輸送層55と電子輸送層57と第2電極58は、複数の発光素子52R、52G、52Bと共通で形成されていてもよいし、発光素子毎に形成されていてもよい。なお、第1電極54と第2電極58とが異物によってショートするのを防ぐために、第1電極54間に絶縁層59が設けられている。さらに、有機EL層は水分や酸素によって劣化するため、水分や酸素から有機EL素子を保護するための保護層60が設けられている。   FIG. 6B is a schematic partial cross-sectional view taken along line AB in FIG. 6A. The pixel 52 includes, on a substrate 53, a first electrode (anode) 54, a hole transport layer 55, one of light-emitting layers 56R, 56G, and 56B, an electron transport layer 57, and a second electrode (cathode) 58. And an organic EL element comprising Among these, the hole transport layer 55, the light emitting layers 56R, 56G, 56B, and the electron transport layer 57 correspond to the organic layers. In the present embodiment, the light emitting layer 56R is an organic EL layer emitting red light, the light emitting layer 56G is an organic EL layer emitting green light, and the light emitting layer 56B is an organic EL layer emitting blue light. The light-emitting layers 56R, 56G, and 56B are formed in patterns corresponding to light-emitting elements that emit red, green, and blue light (may be described as organic EL elements). The first electrode 54 is formed separately for each light emitting element. The hole transport layer 55, the electron transport layer 57, and the second electrode 58 may be formed in common with the plurality of light emitting elements 52R, 52G, 52B, or may be formed for each light emitting element. Note that an insulating layer 59 is provided between the first electrodes 54 to prevent the first electrode 54 and the second electrode 58 from short-circuiting due to foreign matter. Further, since the organic EL layer is deteriorated by moisture and oxygen, a protective layer 60 for protecting the organic EL element from moisture and oxygen is provided.

有機EL層を発光素子単位に形成するためには、マスクを介して成膜する方法が用いられる。近年、表示装置の高精細化が進んでおり、有機EL層の形成には開口の幅が数十μmのマスクが用いられる。   In order to form the organic EL layer for each light emitting element, a method of forming a film via a mask is used. In recent years, the definition of a display device has been improved, and a mask having a width of several tens of μm is used for forming an organic EL layer.

次に、有機EL表示装置の製造方法の例について具体的に説明する。
まず、有機EL表示装置を駆動するための回路(不図示)及び第1電極54が形成された基板53を準備する。
Next, an example of a method for manufacturing an organic EL display device will be specifically described.
First, a circuit (not shown) for driving an organic EL display device and a substrate 53 on which a first electrode 54 is formed are prepared.

第1電極54が形成された基板53の上にアクリル樹脂をスピンコートで形成し、アクリル樹脂をリソグラフィ法により、第1電極54が形成された部分に開口部が形成されるようにパターニングし絶縁層59を形成する。この開口部が、発光素子が実際に発光する発光領域に相当する。   Acrylic resin is formed on the substrate 53 on which the first electrode 54 is formed by spin coating, and the acrylic resin is patterned by lithography so that an opening is formed in a portion where the first electrode 54 is formed, and is insulated. A layer 59 is formed. This opening corresponds to a light emitting area where the light emitting element actually emits light.

絶縁層59がパターニングされた基板53を第1の成膜装置に搬入し、基板保持ユニットにて基板53を保持し、正孔輸送層55を、表示領域の第1電極54の上に共通する層として成膜する。正孔輸送層55は真空蒸着により成膜される。実際には正孔輸送層55は表示領域51よりも大きなサイズに形成されるため、高精細なマスクは不要である。   The substrate 53 on which the insulating layer 59 is patterned is carried into the first film forming apparatus, the substrate 53 is held by the substrate holding unit, and the hole transport layer 55 is shared on the first electrode 54 in the display area. It is formed as a layer. The hole transport layer 55 is formed by vacuum evaporation. Actually, since the hole transport layer 55 is formed in a size larger than the display region 51, a high-definition mask is unnecessary.

次に、正孔輸送層55までが形成された基板53を第2の成膜装置に搬入し、基板保持ユニットにて保持する。基板53とマスクとのアライメントを行い、基板53をマスクの上に載置し、基板53の赤色を発する素子を配置する部分に、赤色を発する発光層56Rを成膜する。   Next, the substrate 53 on which the hole transport layer 55 is formed is carried into the second film forming apparatus, and is held by the substrate holding unit. The alignment between the substrate 53 and the mask is performed, the substrate 53 is placed on the mask, and a red light emitting layer 56R is formed on a portion of the substrate 53 where the element that emits red light is arranged.

発光層56Rの成膜と同様に、第3の成膜装置により緑色を発する発光層56Gを成膜
し、さらに第4の成膜装置により青色を発する発光層56Bを成膜する。発光層56R、56G、56Bの成膜が完了した後、第5の成膜装置により表示領域51の全体に電子輸送層57を成膜する。電子輸送層57は、3色の発光層56R、56G、56Bに共通の層として形成される。
Similarly to the formation of the light-emitting layer 56R, the light-emitting layer 56G that emits green light is formed by the third film formation apparatus, and the light-emitting layer 56B that emits blue light is formed by the fourth film formation apparatus. After the formation of the light emitting layers 56R, 56G, and 56B is completed, the electron transport layer 57 is formed on the entire display area 51 by the fifth film forming apparatus. The electron transport layer 57 is formed as a layer common to the three color light emitting layers 56R, 56G, and 56B.

電子輸送層57までが形成された基板を第6の成膜装置に移動し、第2電極58を成膜し、その後プラズマCVD装置に移動して保護層60を成膜して、有機EL表示装置50が完成する。   The substrate on which the layers up to the electron transport layer 57 are formed is moved to the sixth film forming apparatus, where the second electrode 58 is formed, and then the protective layer 60 is formed by moving to the plasma CVD apparatus to form the organic EL display. The device 50 is completed.

絶縁層59がパターニングされた基板53を成膜装置に搬入してから保護層60の成膜が完了するまでは、水分や酸素を含む雰囲気にさらしてしまうと、有機EL材料からなる発光層が水分や酸素によって劣化してしまうおそれがある。従って、成膜装置間の基板の搬入搬出は、真空雰囲気または不活性ガス雰囲気の下で行われる。   If the substrate 53 on which the insulating layer 59 has been patterned is carried into a film forming apparatus and is exposed to an atmosphere containing moisture or oxygen until the film formation of the protective layer 60 is completed, the light emitting layer made of the organic EL material becomes It may be deteriorated by moisture or oxygen. Therefore, the loading and unloading of the substrate between the film forming apparatuses is performed in a vacuum atmosphere or an inert gas atmosphere.
