Embodiments of the present invention will be described in detail with reference to the drawings.
FIG. 1 is an exploded perspective view showing an embodiment of a substrate storage container of the present invention.
As shown in FIG. 1, the substrate storage container has an opening in the front, and a container body 1 in which support portions 3 for horizontally supporting the substrate in the vertical direction at regular intervals are arranged on the inner wall so as to face each other. And a lid 2 that closes the opening 1 of the container body so as to be sealable is a standard type. At the bottom of the container body, kinematic couplings having V-grooves used for positioning with a processing apparatus or the like are arranged at three locations so as to be Y-shaped. Moreover, the robotic flange for conveyance can be provided in the top | upper surface of a container main body.

蓋体の側面には、シール形成用のシールガスケット5が取り付けられている。また、蓋体の内面には、基板を個別に保持する保持部を弾性片上に備えたリテーナ(図示せず)が取り付けられている。蓋体には、筐体6と、筐体の開口を被覆するカバー7と、外部から操作可能なラッチ機構4とを有し、ラッチ機構は筐体および蓋体に収納・内蔵されている。ラッチ機構は、蓋体に軸支され、外部から操作可能な外部操作係合凹部10を蓋体表面に露呈する回転部材8と、一端が回転部材8と係止されて蓋体側壁の貫通穴から出没可能な連結部材9とを有し、連結部材9の他端が容器本体の連結部材係合凹部11に係合し、蓋体を容器本体1に係止する。   A seal gasket 5 for forming a seal is attached to the side surface of the lid. Further, a retainer (not shown) having a holding portion for holding the substrate individually on the elastic piece is attached to the inner surface of the lid. The lid body includes a housing 6, a cover 7 that covers the opening of the housing, and a latch mechanism 4 that can be operated from the outside. The latch mechanism is housed and incorporated in the housing and the lid body. The latch mechanism includes a rotating member 8 that is pivotally supported by the lid body and exposes an external operation engagement recess 10 that can be operated from the outside to the lid body surface, and one end that is locked to the rotating member 8 so The other end of the connecting member 9 engages with the connecting member engaging recess 11 of the container body, and the lid is locked to the container body 1.

本発明の実施形態の基板収納容器の表面には、さらに透明導電層が形成されていて、この透明導電層は、電子共役系ポリマーにより形成されている。電子共役系ポリマーは、アニリン、ピロール、チオフェンまたはこれらの誘導体から選ばれたモノマーを重合することで形成される(特許文献1参照)。   A transparent conductive layer is further formed on the surface of the substrate storage container of the embodiment of the present invention, and this transparent conductive layer is formed of an electron conjugated polymer. The electron conjugated polymer is formed by polymerizing a monomer selected from aniline, pyrrole, thiophene, or derivatives thereof (see Patent Document 1).

次に、本発明の実施形態の基板収納容器の製造方法について説明する。ここでは、電子共役系ポリマーとしてピロールを用いる例を説明するが、本発明は、これに限られない。
容器本体と蓋体とは、視認性の良好なポリカーボネート、シクロオレフィンポリマー、ポリエーテルイミド、アクリル樹脂などの熱可塑性樹脂から形成することが好ましい。支持部材、リテーナ、位置決め部材等は、上記の樹脂のほかに、ポリブチレンテレフクレート、ポリエーテルエーテルケトン、ポリエーテルサルフォンなどの合成樹脂や、ポリオレフィン系、ポリエステル系、ポリスチレン系などの各種熱可塑性エラストマー樹脂を用いて形成される。
Next, the manufacturing method of the substrate storage container of the embodiment of the present invention will be described. Here, an example in which pyrrole is used as the electron conjugated polymer will be described, but the present invention is not limited to this.
The container body and the lid are preferably formed from a thermoplastic resin such as polycarbonate, cycloolefin polymer, polyetherimide, or acrylic resin with good visibility. Support members, retainers, positioning members, etc., in addition to the above resins, synthetic resins such as polybutylene terephthalate, polyether ether ketone, and polyether sulfone, and various thermoplastics such as polyolefin, polyester, and polystyrene It is formed using an elastomer resin.

容器本体や蓋体は、上記した樹脂を用いて、射出成形によって形成される。このように形成された容器本体や蓋体は、検査された後に、容器本体にはロボティックハンドルやマニュアルハンドルといった搬送部品や、識別用のボトムプレート、蓋体には、シールガスケットやリテーナ等の付属部品が取り付けられる。   The container body and the lid are formed by injection molding using the above-described resin. After the container body and lid formed in this way are inspected, the container body has transport parts such as robotic handles and manual handles, the identification bottom plate, and the lid body such as a seal gasket and a retainer. Attached parts are attached.

次に、容器本体と蓋体の表面に、透明導電層を形成する。
透明導電層は、容器本体や蓋体が1又は複数個収納できるような処理槽に、ドーパント作用を有する酸化重合剤またはドーパントを含む酸化重合剤溶液を注入し、この溶液中に容器本体と蓋体とを浸漬する。引き続いて、ピロール水溶液を処理槽に供給し、処理槽に備付けられた攪拌機を用いて処理溶液をゆっくりと攪拌しながら処理溶液中に容器本体と蓋体とを浸漬保持する。このとき、容器本体と蓋体の表面に上記した処理液が接触し、ドーパントの存在下にモノマーが重合されるので、ポリピロールが生成する。
Next, a transparent conductive layer is formed on the surface of the container body and the lid.
The transparent conductive layer is prepared by injecting an oxidizing polymerizer having a dopant action or an oxidizing polymerizer solution containing a dopant into a treatment tank in which one or a plurality of container bodies and lids can be accommodated. Immerse the body. Subsequently, the pyrrole aqueous solution is supplied to the treatment tank, and the container body and the lid are immersed and held in the treatment solution while slowly stirring the treatment solution using a stirrer provided in the treatment tank. At this time, the treatment liquid described above comes into contact with the surfaces of the container body and the lid, and the monomer is polymerized in the presence of the dopant, so that polypyrrole is generated.

処理液へのモノマーおよび酸化重合剤の添加は、両者を一緒に添加することができるし、先にモノマーを添加しその後酸化重合剤を添加しても良い。また、酸化重合剤は、一括添加してもよく、あるいは数回に分けて添加しても、少量ずつ連続して添加してもよい。
触媒の酸化重合剤としては、ピロールモノマーの重合を促進する物質を使用することができ、例えば、過硫酸、過硫酸アンモニウム、過硫酸カリウム、過硫酸ナトリウム等の過硫酸塩類、あるいは、塩化第二鉄、硫酸第二鉄、硫酸アンモニウム第二鉄、クエン酸第二鉄等の第二鉄塩、過マンガン酸塩、塩素、臭素等のハロゲン、過酸化水素、過酸化ベンゾイル等の過酸化物などを挙げることができる。
The monomer and the oxidative polymerization agent can be added to the treatment liquid together. Alternatively, the monomer may be added first and then the oxidative polymerization agent may be added. In addition, the oxidation polymerization agent may be added all at once, or may be added in several portions, or may be added continuously little by little.
As the oxidative polymerization agent for the catalyst, a substance that accelerates the polymerization of the pyrrole monomer can be used. For example, persulfates such as persulfuric acid, ammonium persulfate, potassium persulfate, sodium persulfate, or ferric chloride. , Ferric sulfate such as ferric sulfate, ferric ammonium sulfate and ferric citrate, permanganate, halogen such as chlorine and bromine, peroxide such as hydrogen peroxide and benzoyl peroxide, etc. be able to.

ピロールモノマーを重合するにあたって、導電性を高めるために、ドーパントを併用することが好ましい。ドーパントとしては、例えば、p―トルエンスルホン酸、ベンゼンスルホン酸、アントラキノンスルホン酸、モノクロロベンゼンスルホン酸、ジクロロベンゼンスルホン酸、トリクロロベンゼンスルホン酸、ナフタレンスルホン酸、スルホサリチル酸およびその他の芳香族スルホン酸、あるいは、過塩素酸、塩酸、硫酸、硝酸、トリフルオロスルホン酸などが挙げられる。   In polymerizing the pyrrole monomer, it is preferable to use a dopant in combination in order to increase conductivity. Examples of the dopant include p-toluenesulfonic acid, benzenesulfonic acid, anthraquinonesulfonic acid, monochlorobenzenesulfonic acid, dichlorobenzenesulfonic acid, trichlorobenzenesulfonic acid, naphthalenesulfonic acid, sulfosalicylic acid and other aromatic sulfonic acids, or Perchloric acid, hydrochloric acid, sulfuric acid, nitric acid, trifluorosulfonic acid and the like.

このようにして容器本体と蓋体の表面に導電層が均一に付与される。導電層が付与された容器本体と蓋体表面の表面抵抗値は、処理層での反応時間および生成する導電層の厚みにより、JIS K−6911に準拠して測定したときに、1×103〜9×108Ωの範囲に入るように調整するのが好ましい。導電層の厚みは、20〜100nm、好ましくは40〜60nmとすることができる。20nm以上では、使用中の剥離がなく、表面抵抗値も9×108Ω以下とすることができる。また、l00nm以下だと、表面抵抗埴を103Ωと低くできるし、全光線透過率を40%以上とすることができる。導電層の厚みを40〜60nmとすれば、表面抵抗を103〜107Ωの範囲とでき、全光線透過率を65%以上とできるのでより好ましい。このように、容器本体及び又は蓋体の表面抵抗値と全光線透過率が調整される。 In this way, the conductive layer is uniformly applied to the surfaces of the container body and the lid. The surface resistance value of the container body to which the conductive layer is applied and the lid surface is 1 × 10 3 when measured according to JIS K-6911 depending on the reaction time in the treatment layer and the thickness of the conductive layer to be formed. It is preferable to adjust so that it may fall in the range of ˜9 × 10 8 Ω. The thickness of the conductive layer can be 20 to 100 nm, preferably 40 to 60 nm. When the thickness is 20 nm or more, there is no peeling during use, and the surface resistance value can be 9 × 10 8 Ω or less. On the other hand, when it is 100 nm or less, the surface resistance can be lowered to 10 3 Ω, and the total light transmittance can be 40% or more. If the thickness of the conductive layer is 40 to 60 nm, the surface resistance can be in the range of 10 3 to 10 7 Ω, and the total light transmittance can be 65% or more, which is more preferable. In this way, the surface resistance value and the total light transmittance of the container body and / or lid are adjusted.

容器本体と蓋体とは処理槽での一定時間の浸漬の後、取り出されて、純水にて洗浄されて、乾燥がなされる。このようにして得られる容器本体と蓋体とは、表面近傍に形成された電子共役系ポリマーにより導電性が付与されたものとなる。また、表面全域を、電子共役ポリマーで被覆しているので、容器本体や蓋体を形成する樹脂の揮発成分が、基板収納容器を常温で24時間放置したときに、容器内部に充満してくることを防止できる。特には、半導体部品の回路を腐触する恐れのある塩化メチレンの発生量をブランクとなる保管環境の空気の値以下、好ましくは3μg/m3以下とすることができる。
ここで、半導体部品の回路に与える影響を求める目安として、図1に示す容器に模擬的に市販のハンダボールを入れて蓋体を閉め、80℃で保管した際にハンダボールの外観・色調変化が発生するまでの時間を確認した。
常温で24時間放置した際の塩化メチレンの発生量が5μg/m3の場合、ハンダボール表面に変色が生ずるまでの時間は10日間、9μg/m3の場合6日間、一方、3μg/m3の場合は30日間であり、実用上の使用環境に十分耐えうる結果であった。
The container main body and the lid body are taken out after being immersed in the treatment tank for a certain period of time, and are then washed with pure water and dried. The container body and the lid obtained in this way are given conductivity by an electron conjugated polymer formed in the vicinity of the surface. Further, since the entire surface is covered with the electron conjugated polymer, the volatile components of the resin forming the container body and the lid body fill the inside of the container when the substrate storage container is left at room temperature for 24 hours. Can be prevented. In particular, the amount of methylene chloride that may corrode the circuit of the semiconductor component can be made to be not more than the value of air in the storage environment as a blank, preferably not more than 3 μg / m 3 .
Here, as a guideline for determining the influence of the semiconductor component on the circuit, the appearance and color tone change of the solder ball when stored in the container shown in FIG. Confirmed the time to occur.
When the amount of methylene chloride generated at room temperature for 24 hours is 5 μg / m 3 , the time until discoloration occurs on the solder ball surface is 10 days, when it is 9 μg / m 3 , it is 6 days, while 3 μg / m 3 In this case, it was 30 days, and it was a result that could sufficiently withstand the practical use environment.

基板収納容器の溶出イオンは、次のように測定することができる。
容器本体に純水を1リットル注ぎ、前後左右に3回づつ揺動させた後、容器本体をオーブンにて50℃×3時間保持する間に、純水中に抽出(溶出)された塩素イオン量と硫酸イオン量をイオンクロマトグラフにより分析する。
容器本体から抽出されるイオンの基板収納容器1個当たりの塩酸イオン量が600ng/Box以下、硫酸イオンが600ng/Box以下であることが実用上好ましい。
The eluted ions in the substrate storage container can be measured as follows.
After pouring 1 liter of pure water into the container body, rocking it three times in front, back, left, and right, the chlorine ions extracted (eluted) in pure water while holding the container body in an oven at 50 ° C. for 3 hours The amount and sulfate ion amount are analyzed by ion chromatography.
It is practically preferable that the amount of hydrochloric acid ions per one substrate storage container of ions extracted from the container main body is 600 ng / Box or less and the sulfate ions are 600 ng / Box or less.
