本發明係關於一種保護膜形成膜、保護膜形成用複合片、半導體裝置之製造方法、以及保護膜形成膜之使用。 本案係基於2022年3月30日在日本提出申請之日本特願2022-055428號主張優先權,且將該申請案的內容引用至本文中。 The present invention relates to a protective film-forming film, a protective film-forming composite sheet, a manufacturing method of a semiconductor device, and the use of the protective film-forming film. This case claims priority based on Japanese Patent Application No. 2022-055428 filed in Japan on March 30, 2022, and the contents of the application are cited in this article.
於半導體晶圓,有些在其中一面(電路面)形成有電路,進而在該面(電路面)上具有凸塊等突狀電極。這種半導體晶圓係藉由分割而作成半導體晶片,使該突狀電極被連接於電路基板上的連接墊,而搭載於前述電路基板。 為了抑制在這種半導體晶圓或半導體晶片之中產生龜裂等破損,有時將與電路面為相反側之面(內面)以保護膜來進行保護。 Some semiconductor wafers have circuits formed on one side (circuit surface), and have protruding electrodes such as bumps on this surface (circuit surface). This semiconductor wafer is divided into semiconductor wafers, and the protruding electrodes are connected to connection pads on the circuit board, and then mounted on the circuit board. In order to suppress the occurrence of damage such as cracks in such a semiconductor wafer or semiconductor wafer, the surface opposite to the circuit surface (inner surface) may be protected with a protective film.
為了形成這種保護膜,係於半導體晶圓的內面貼附用以形成保護膜之保護膜形成膜。保護膜形成膜係被積層於用以支撐此保護膜形成膜之支撐片上,亦有時以保護膜形成用複合片的狀態來使用,亦有時不積層於支撐片上來使用。然後,通常於內面具備保護膜形成膜之半導體晶圓(具保護膜形成膜之半導體晶圓)在經過之後的各種步驟而加工成為於內面具備保護膜之半導體晶片(具保護膜之半導體晶片)。這種具保護膜之半導體晶片在拾取後被搭載於基板的電路面,構成半導體裝置。保護膜形成膜係例如藉由硬化而形成保護膜。In order to form such a protective film, a protective film-forming film for forming a protective film is attached to the inner surface of the semiconductor wafer. The protective film-forming film is laminated on a support sheet for supporting the protective film-forming film. It may be used in the form of a protective film-forming composite sheet, or may be used without being laminated on the support sheet. Then, a semiconductor wafer having a protective film-forming film on its inner surface (a semiconductor wafer with a protective film-forming film) is usually processed into a semiconductor wafer having a protective film on its inner surface (a semiconductor wafer with a protective film) through various subsequent steps. wafer). This semiconductor wafer with a protective film is picked up and mounted on the circuit surface of the substrate to form a semiconductor device. The protective film-forming film system forms a protective film by curing, for example.
保護膜形成膜最終能夠在保護膜的狀態下充分地保護半導體晶片的內面,要求抑制於半導體晶片中產生微小的缺損(亦即碎屑)。並且,順應這種目的之保護膜形成膜已被揭示(參照專利文獻1)。 [先前技術文獻] [專利文獻] The protective film-forming film is required to sufficiently protect the inner surface of the semiconductor wafer in the form of a protective film and to suppress the occurrence of minute defects (that is, chips) in the semiconductor wafer. Furthermore, a protective film-forming film that meets this purpose has been disclosed (see Patent Document 1). [Prior technical literature] [Patent Document]
[專利文獻1]日本專利第4897979號公報。[Patent Document 1] Japanese Patent No. 4897979.
[發明所欲解決之課題][Problem to be solved by the invention]
此外,保護膜形成膜之中,藉由加熱進行硬化之熱硬化性的保護膜形成膜,通常建議在製造之後當下至使用時為止進行冷藏保存。理由在於,當不將保護膜形成膜進行冷藏而保存之情形時,保護膜形成膜的穩定性低,有可能導致表現熱硬化性所必要的保護膜形成膜的含有成分之一部分於保存中進行反應,而在實際使用時使得保護膜形成膜無法充分地發揮功能。然而,於冷藏保存的情形時,相較於常溫保存的情形時在保存所需要的成本更高,保護膜形成膜的操作亦繁雜。因此,近年來有需要對於即使以常溫保存亦可無問題地使用之保護膜形成膜。 相對於此,在專利文獻1所揭示之保護膜形成膜在常溫保存之情形時的穩定性低。 Furthermore, among the protective film-forming films, thermosetting protective film-forming films that are cured by heating are generally recommended to be refrigerated after production until use. The reason is that when the protective film-forming film is stored without refrigeration, the stability of the protective film-forming film is low, and part of the components contained in the protective film-forming film necessary to express thermosetting properties may be lost during storage. reaction, which prevents the protective film-forming film from fully functioning during actual use. However, in the case of refrigerated storage, the cost of storage is higher than in the case of normal temperature storage, and the operation of forming a protective film is also complicated. Therefore, in recent years, there has been a need to form a protective film that can be used without problems even when stored at room temperature. In contrast, the protective film-forming film disclosed in Patent Document 1 has low stability when stored at room temperature.

藉由將常溫的保護膜形成膜加熱至超過常溫之溫度為止,繼而冷卻至常溫為止,作成加熱、冷卻後的保護膜形成膜,當將加熱、冷卻後的保護膜形成膜的硬度以及加熱前的保護膜形成膜的硬度以相同溫度進行比較時,當在加熱、冷卻後的保護膜形成膜較硬的情形時,該保護膜形成膜為熱硬化性。By heating the protective film forming film at normal temperature to a temperature exceeding normal temperature and then cooling it to normal temperature, a protective film forming film after heating and cooling is produced. When the hardness of the protective film forming film after heating and cooling is compared with the hardness of the protective film forming film before heating. When the hardness of the protective film-forming film is compared at the same temperature, if the protective film-forming film after heating and cooling is harder, the protective film-forming film is thermosetting.
本實施形態之保護膜形成膜可由1層(單層)所構成,亦可由2層以上之多層所構成。於保護膜形成膜由多層所構成之情形時,這些多層相互可相同亦可不同,這些多層的組合並無特別限定。The protective film-forming film of this embodiment may be composed of one layer (single layer), or may be composed of multiple layers of two or more layers. When the protective film-forming film is composed of multiple layers, these multiple layers may be the same as or different from each other, and the combination of these multiple layers is not particularly limited.
本說明書之中,不限於保護膜形成膜之情形,所謂「多層相互可相同亦可不同」,意指「可所有層相同,亦可所有層皆不同,還可僅一部分層相同」,進而,所謂「多層相互不同」,意指「各層的構成材料及厚度的至少一者相互不同」。In this specification, the term "multiple layers may be the same or different from each other" is not limited to the case where the protective film is formed into a film, which means "all the layers may be the same, all the layers may be different, or only some of the layers may be the same", and further, The term "multiple layers are different from each other" means that "at least one of the constituent materials and thickness of each layer is different from each other."
[發熱起始溫度] 在DSC之前述試片的發熱起始溫度為160℃以上,較佳為170℃以上,例如亦可為173℃以上、176℃以上、以及180℃以上之中任一者。前述發熱起始溫度越高,保護膜形成膜在常溫之保存穩定性越高。 前述發熱起始溫度的上限值並無特別限定。例如由容易獲得保護膜形成膜的方面來看,前述發熱起始溫度亦可為195℃以下。 一實施形態中,前述發熱起始溫度例如亦可為160℃至195℃、170℃至195℃、173℃至195℃、176℃至195℃、以及180℃至195℃中任一者。然而,這些溫度為前述發熱起始溫度之一例。 [Fever starting temperature] The heat generation starting temperature of the test piece before DSC is 160°C or higher, preferably 170°C or higher, and may be any one of 173°C or higher, 176°C or higher, and 180°C or higher. The higher the aforementioned heating onset temperature, the higher the storage stability of the protective film-forming film at room temperature. The upper limit of the aforementioned heat generation starting temperature is not particularly limited. For example, from the viewpoint of easily obtaining a protective film-forming film, the heat generation starting temperature may be 195°C or lower. In one embodiment, the heat generation starting temperature may be, for example, any one of 160°C to 195°C, 170°C to 195°C, 173°C to 195°C, 176°C to 195°C, and 180°C to 195°C. However, these temperatures are examples of the aforementioned heat generation starting temperatures.
供於DSC之前述試片的形態只要是可以高精度進行DSC,則並無特別限定。例如能夠藉由積層多片保護膜形成膜,切成適切的形狀而製作前述試片。作為試片,例如只要是4mg至10mg左右的質量即為充分。The form of the test piece to be used for DSC is not particularly limited as long as it can perform DSC with high accuracy. For example, the test piece can be produced by laminating a plurality of protective films to form a film and cutting it into an appropriate shape. As a test piece, it is sufficient if it has a mass of about 4 mg to 10 mg, for example.
在DSC之前述試片的發熱起始溫度係被定義為如下的溫度:例如顯示DSC曲線(將DSC資料經繪圖所獲得之曲線)的微分曲線在最初顯示負值之點之切線與前述微分曲線在顯示極大值(最初被觀測到之極值)之溫度之切線的交點的溫度。The heating onset temperature of the test piece before DSC is defined as the following temperature: For example, the tangent line between the point where the differential curve showing the DSC curve (the curve obtained by plotting the DSC data) initially shows a negative value and the aforementioned differential curve The temperature at the intersection of the tangent line to the temperature showing the maximum value (the extreme value initially observed).
在DSC之前述試片的發熱起始溫度能夠藉由調節前述保護膜形成膜的含有成分的種類以及含量而加以調節。 例如,於保護膜形成膜含有後述之硬化促進劑(C)之情形時,能夠藉由調節硬化促進劑(C)的反應性,更容易地調節前述發熱起始溫度。更具體而言,例如,能夠藉由選擇反應起始溫度較低者作為硬化促進劑(C),增加這種硬化促進劑(C)的含量,而提高前述發熱起始溫度。 例如,於保護膜形成膜含有後述之熱硬化劑(B2)之情形時,為了提高前述發熱起始溫度,較佳係選擇在常溫為固體狀者作為熱硬化劑(B2)。 The heat generation starting temperature of the test piece before DSC can be adjusted by adjusting the type and content of the components contained in the protective film-forming film. For example, when the protective film-forming film contains a hardening accelerator (C) described below, the heat generation starting temperature can be more easily adjusted by adjusting the reactivity of the hardening accelerator (C). More specifically, for example, by selecting one with a lower reaction start temperature as the hardening accelerator (C) and increasing the content of the hardening accelerator (C), the heat generation start temperature can be increased. For example, when the protective film-forming film contains a thermosetting agent (B2) described below, in order to increase the heat generation starting temperature, it is preferable to select a thermosetting agent (B2) that is solid at room temperature.
保護膜形成膜的厚度並無特別限定。 保護膜形成膜的厚度較佳為50μm以下,例如亦可為40μm以下、以及30μm以下之中任一者。藉由保護膜形成膜的厚度為前述上限值以下,避免保護膜形成膜的厚度變得過剩。 另一方面,保護膜形成膜的厚度在能夠形成保護性能更高的保護膜的方面來看,較佳為5μm以上。 一實施形態中,保護膜形成膜的厚度例如亦可為5μm至50μm、5μm至40μm、以及5μm至30μm中任一者。然而,這些厚度為保護膜形成膜的厚度之一例。 The thickness of the protective film-forming film is not particularly limited. The thickness of the protective film-forming film is preferably 50 μm or less, and may be any of 40 μm or less and 30 μm or less, for example. By setting the thickness of the protective film-forming film to be equal to or less than the aforementioned upper limit, the thickness of the protective film-forming film can be prevented from becoming excessive. On the other hand, the thickness of the protective film-forming film is preferably 5 μm or more in order to form a protective film with higher protective performance. In one embodiment, the thickness of the protective film forming film may be, for example, any one of 5 μm to 50 μm, 5 μm to 40 μm, and 5 μm to 30 μm. However, these thicknesses are examples of the thicknesses of the protective film forming films.

For example, the so-called thickness of the protective film-forming film composed of multiple layers means all the layers constituting the protective film-forming film. the total thickness.

Unless otherwise specified, it is a value expressed as the average of the thicknesses measured at five randomly selected locations in the object. It can be based on JIS K7130. Use a constant pressure thickness gauge to obtain it.
將前述保護膜形成膜貼附於半導體晶圓的目標部位,進行熱硬化而形成保護膜時的硬化條件,只要保護膜成為充分地發揮功能之程度的硬化度,則並無特別限定,根據保護膜形成膜的種類而適當選擇即可。The curing conditions when the protective film-forming film is attached to a target portion of the semiconductor wafer and thermally cured to form a protective film are not particularly limited as long as the protective film has a degree of curing that allows it to fully function. Depending on the protection The type of film forming film may be appropriately selected.
例如,保護膜形成膜的熱硬化時的加熱溫度亦可為100℃至200℃、110℃至180℃、以及120℃至160℃中任一者。 前述熱硬化時的加熱時間,考慮加熱溫度而適當設定即可,例如亦可為3分鐘至5小時、10分鐘至4小時、以及30分鐘至3小時中任一者。 For example, the heating temperature during thermosetting of the protective film-forming film may be any one of 100°C to 200°C, 110°C to 180°C, and 120°C to 160°C. The heating time during thermal hardening may be appropriately set in consideration of the heating temperature. For example, it may be any one of 3 minutes to 5 hours, 10 minutes to 4 hours, and 30 minutes to 3 hours.

The protective film-forming film of this embodiment has good adhesion to the inner surface of the semiconductor wafer, and has high protective performance of the semiconductor wafer. Even when the protective film-forming film of this embodiment is stored at normal temperature, it suppresses unintended reactions containing components necessary to express thermosetting properties. That is, the protective film-forming film of this embodiment has high stability when stored at room temperature. Therefore, for example, even after the protective film-forming film is stored at normal temperature for 30 days, the adhesion is still good when it is attached to the inner surface of the semiconductor wafer, and the protective performance of the semiconductor wafer is still high.
[保護膜形成用組成物] 前述保護膜形成膜能夠使用含有該構成材料之保護膜形成用組成物(更具體而言為熱硬化性保護膜形成用組成物)來形成。例如,保護膜形成膜能夠藉由在該形成對象面塗敷保護膜形成用組成物,並視需要進行乾燥來形成。保護膜形成用組成物中在常溫下不會氣化之成分彼此的含量之比率通常與保護膜形成膜中之前述成分彼此的含量之比率相同。 [Composition for protective film formation] The protective film-forming film can be formed using a protective film-forming composition (more specifically, a thermosetting protective film-forming composition) containing the constituent material.

The ratio of the contents of components that do not vaporize at normal temperature in the protective film-forming composition to each other is generally the same as the ratio of the contents of the aforementioned components to each other in the protective film-forming film.

Examples of energy rays include ultraviolet rays, radiation, electron beams, and the like. Ultraviolet rays can be irradiated by using, for example, a high-pressure mercury lamp, a fusion lamp, a xenon lamp, a black light lamp, or an LED (Light Emitting Diode) lamp as an ultraviolet source.

By setting the aforementioned content of the hardening accelerator (C) to be above the aforementioned lower limit, the effect of using the hardening accelerator (C) can be more significantly obtained. By setting the content of the hardening accelerator (C) below the aforementioned upper limit, for example, the highly polar hardening accelerator (C) is prevented from moving in the protective film-forming film to adhere to the adherend under conditions of high temperature and high humidity.

◇保護膜形成用複合片之製造方法 前述保護膜形成用複合片可藉由成為對應上述之各層之位置關係的方式進行積層,並視需要調節一部分或是所有層的形狀來製造。各層的形成方法係如前文所說明。 ◇Production method of composite sheet for protective film formation The composite sheet for forming a protective film can be produced by laminating the layers so as to correspond to the positional relationship of the above-mentioned layers and adjusting the shapes of some or all of the layers as necessary. The formation methods of each layer are as described above.
例如在製造支撐片時,於基材上積層黏著劑層之情形時,只要於基材上塗敷上述之黏著劑組成物,並視需要進行乾燥即可。 另外,即使是藉由於剝離膜上塗敷黏著劑組成物,並視需要乾燥,於剝離膜上預先形成黏著劑層,將該黏著劑層的露出面貼合於基材的一表面之方法,亦可於基材上積層黏著劑層。此時,黏著劑組成物較佳係塗敷於剝離膜的剝離處理面。另外,此情形之剝離膜可在保護膜形成用複合片之製造過程或使用過程中任一時機移除即可。 至此為止,列舉了於基材上積層黏著劑層之情形之例,然上述之方法亦可適用在例如於基材上積層黏著劑層以外的其他層之情形時。 For example, when manufacturing a support sheet and laminating an adhesive layer on a base material, it is sufficient to apply the above-mentioned adhesive composition on the base material and dry it if necessary. In addition, even the method of forming an adhesive layer on the release film in advance by applying an adhesive composition on the release film and drying it if necessary, and bonding the exposed surface of the adhesive layer to a surface of the base material is also applicable. An adhesive layer can be laminated on the substrate. At this time, the adhesive composition is preferably applied to the release-treated surface of the release film. In addition, the release film in this case may be removed at any time during the manufacturing process or use of the protective film-forming composite sheet. So far, the example in which an adhesive layer is laminated on a base material has been exemplified. However, the above method may also be applied when, for example, a layer other than an adhesive layer is laminated on a base material.
另一方面,例如於已積層於基材上的黏著劑層之上,進而積層保護膜形成膜之情形時,可於黏著劑層上塗敷保護膜形成用組成物,直接形成保護膜形成膜。保護膜形成膜以外的層亦可使用用以形成該層之組成物,並以相同的方法於黏著劑層之上積層該層。如此,於已積層於基材上之任一層(以下縮寫為「第一層」)上形成新的層(以下縮寫為「第二層」),來形成連續之2層的積層結構(換言之為第一層以及第二層的積層結構)之情形時,可適用如下之方法:於前述第一層上塗敷用以形成前述第二層之組成物,並視需要進行乾燥。 其中,第二層較佳係藉由使用用以形成第二層之組成物而預先形成於剝離膜上,將此已形成的第二層中與接觸於前述剝離膜之側為相反側之露出面貼合於第一層的露出面,而形成連續之2層的積層結構。此時,前述組成物較佳係塗敷於剝離膜的剝離處理面。剝離膜係在形成積層結構後視需要移除即可。 此處,雖然列舉了於黏著劑層上積層保護膜形成膜之情形為例,但例如於黏著劑層上積層保護膜形成膜以外的層(膜)之情形等,可任意選擇作為對象之積層結構。 On the other hand, for example, when a protective film is laminated on an adhesive layer laminated on a substrate to form a film, the protective film-forming composition can be applied on the adhesive layer to directly form a protective film-forming film. The composition for forming this layer can also be used as a layer other than the protective film-forming film, and this layer can be laminated on the adhesive layer in the same manner. In this way, a new layer (hereinafter abbreviated as the "second layer") is formed on any layer that has been laminated on the substrate (hereinafter abbreviated as the "first layer") to form a continuous 2-layer laminated structure (in other words In the case of a laminated structure of a first layer and a second layer), the following method can be applied: apply a composition for forming the second layer on the first layer, and dry it if necessary. Among them, the second layer is preferably formed in advance on the release film by using a composition for forming the second layer, and the side of the formed second layer opposite to the side in contact with the release film is exposed. The surface is attached to the exposed surface of the first layer to form a continuous two-layer laminated structure. At this time, the composition is preferably applied to the release-treated surface of the release film. The peel-off film can be removed if necessary after forming a laminated structure. Here, the case where a protective film is laminated on the adhesive layer to form a film is given as an example. However, for example, when a layer (film) other than a protective film is laminated on the adhesive layer, the target laminate can be selected arbitrarily. structure.
如此,由於構成保護膜形成用複合片之基材以外的層皆能以預先形成於剝離膜上再貼合於目的層的表面之方法進行積層,故只要視需要適當選擇採用這種步驟之層,來製造保護膜形成用複合片即可。In this way, since the layers other than the base material constituting the composite sheet for forming a protective film can be laminated by a method of being formed in advance on the release film and then bonded to the surface of the target layer, it is only necessary to appropriately select the layer using this step as necessary. , to produce a composite sheet for protective film formation.
此外,保護膜形成用複合片通常係於與該支撐片為相反側之最表層(例如保護膜形成膜)的表面貼合有剝離膜之狀態來儲存。因此,於該剝離膜(較佳為剝離膜之剝離處理面)上塗敷保護膜形成用組成物等用以形成構成最表層之層之組成物,並視需要進行乾燥,藉此於剝離膜上預先形成構成最表層之層,於該層中與剝離膜接觸之側為相反側之露出面上積層剩餘的各層,不移除剝離膜而保持貼合之狀態,藉此獲得具剝離膜之保護膜形成用複合片。In addition, the composite sheet for protective film formation is usually stored in a state where a release film is bonded to the surface of the outermost layer (for example, the protective film forming film) on the opposite side to the support sheet. Therefore, a composition for forming a layer constituting the outermost layer, such as a protective film-forming composition, is applied to the release film (preferably the release-treated surface of the release film), and dried if necessary, thereby forming a protective film on the release film. A layer constituting the outermost layer is formed in advance, and the remaining layers are laminated on the exposed surface opposite to the side in contact with the peeling film. The peeling film remains attached without removing the peeling film, thereby obtaining the protection of the peeling film. Composite sheet for film formation.

In the attachment step, the protective film-forming film 13 has good adhesion to the semiconductor wafer 9 . For example, even if the protective film-forming film 13 stored at normal temperature is used, the adhesion of the protective film-forming film 13 to the semiconductor wafer 9 is still good. Therefore, the protective performance of the semiconductor wafer provided by the protective film is also high.

[印字步驟] 製造方法(1)之前述熱硬化步驟之後,前述印字步驟之中,如圖4C所示,藉由於保護膜形成用複合片101’中之保護膜13’的支撐片10側之面(亦即第二面13b’)照射雷射光R,於前述面進行雷射印字。 雷射印字能夠以公知的方法來進行。例如,藉由將雷射光R的波長設為300nm至1100nm、掃描速度設為50mm/s至1000mm/s而照射雷射光R,能夠良好地進行雷射印字。作為代表性的雷射光R的波長,例如可列舉:355nm、532nm、1064nm等,這些波長為其中一例。 [Print steps] Manufacturing method (1) After the aforementioned thermal hardening step, during the aforementioned printing step, as shown in FIG. 4C , the surface of the protective film 13 ′ in the protective film forming composite sheet 101 ′ on the support sheet 10 side (that is, The second surface 13b') is irradiated with laser light R, and laser printing is performed on the aforementioned surface. Laser printing can be performed by a known method. For example, by irradiating the laser light R with a wavelength of 300 nm to 1100 nm and a scanning speed of 50 mm/s to 1000 mm/s, laser printing can be performed satisfactorily. Typical wavelengths of the laser light R include, for example, 355 nm, 532 nm, 1064 nm, and the like, and these wavelengths are examples.
[加工步驟] 製造方法(1)之前述印字步驟之後,前述加工步驟之中,於保護膜形成用複合片101’中之支撐片10上將半導體晶圓9分割成半導體晶片90,沿著半導體晶圓9的分割部位來切斷保護膜13’。藉此,如圖4D所示,製作具備半導體晶片90以及設置於半導體晶片90的內面90b之切斷後的保護膜130’之具保護膜之半導體晶片913’,且製作多個具保護膜之半導體晶片913’被固定在支撐片10上整齊排列所構成之具保護膜之半導體晶片群902。 圖4D中,符號130a’係表示切斷後的保護膜130’的第一面,對應保護膜13’的第一面13a’。另外,符號130b’係表示切斷後的保護膜130’的第二面,對應保護膜13’的第二面13b’。另外,符號90a係表示半導體晶片90的電路面,對應半導體晶圓9的電路面9a。 [Processing steps] Manufacturing method (1) After the aforementioned printing step and during the aforementioned processing step, the semiconductor wafer 9 is divided into semiconductor wafers 90 on the support sheet 10 in the protective film forming composite sheet 101'. Cut off the protective film 13' at the divided part. Thereby, as shown in FIG. 4D , a semiconductor wafer with a protective film 913 ′ including the semiconductor wafer 90 and the cut protective film 130 ′ provided on the inner surface 90 b of the semiconductor wafer 90 is produced, and a plurality of semiconductor wafers with a protective film are produced. The semiconductor wafer 913' is fixed on the support sheet 10 and is arranged in a neatly arranged semiconductor wafer group 902 with a protective film. In Figure 4D, symbol 130a' represents the first surface of the cut protective film 130', corresponding to the first surface 13a' of the protective film 13'. In addition, the symbol 130b' represents the second surface of the cut protective film 130', corresponding to the second surface 13b' of the protective film 13'. In addition, reference numeral 90a indicates the circuit surface of the semiconductor wafer 90 and corresponds to the circuit surface 9a of the semiconductor wafer 9.
製造方法(1)的加工步驟之中,例如亦可同時進行半導體晶圓9的分割與保護膜13’的切斷,亦可在進行半導體晶圓9的分割之後,進行保護膜13’的切斷。 製造方法(1)之中,在藉由不論順序且不中斷的同一操作來連續進行半導體晶圓的分割與保護膜的切斷之情形時,視為半導體晶圓的分割與保護膜形成膜的切斷同時進行。 In the processing steps of the manufacturing method (1), for example, the dividing of the semiconductor wafer 9 and the cutting of the protective film 13' may be performed simultaneously, or the protective film 13' may be cut after the dividing of the semiconductor wafer 9. break. In the manufacturing method (1), when the dividing of the semiconductor wafer and the cutting of the protective film are continuously performed by the same operation regardless of the order and without interruption, the dividing of the semiconductor wafer and the forming of the protective film are regarded as Cut off at the same time.
半導體晶圓9的分割與保護膜13’的切斷皆能夠根據進行這些的順序而以公知的方法來進行。Both the division of the semiconductor wafer 9 and the cutting of the protective film 13' can be performed by a known method according to the order in which these are performed.
例如,使用刀片之刀片切割、藉由照射雷射光之雷射切割、或是藉由噴附含有研磨劑之水之水力切割等各種切割,藉此可同時進行半導體晶圓9的分割與保護膜13’的切斷。 另外,就算是藉由隱形切割(註冊商標)形成改質層,且與未進行分割之半導體晶圓9與保護膜13’一起在平行於這些表面的方向進行拉伸(進行所謂擴展(expand)),也可以同時進行半導體晶圓9的分割與保護膜13’的切斷。這種擴展較佳係在-20℃至5℃等低溫進行。 For example, various cutting methods such as blade cutting using a blade, laser cutting by irradiating laser light, or hydraulic cutting by spraying water containing abrasives can be used to simultaneously separate and protect the semiconductor wafer 9 . 13' cut off. In addition, even if the modified layer is formed by stealth dicing (registered trademark), and the undivided semiconductor wafer 9 and the protective film 13' are stretched in a direction parallel to these surfaces (so-called expansion is performed) ), the division of the semiconductor wafer 9 and the cutting of the protective film 13' may be performed simultaneously. This expansion is best carried out at low temperatures such as -20°C to 5°C.
所謂隱形切割(註冊商標),係如以下之方法。亦即,首先,藉由於半導體晶圓的內部設定預定分割部位,將該部位設為焦點,以聚焦於該焦點的方式照射雷射光,於半導體晶圓的內部形成改質層。半導體晶圓的改質層與半導體晶圓的其他部位不同,藉由照射雷射光而改質,強度變弱。因此,藉由於半導體晶圓施加力,半導體晶圓的內部的改質層中,產生朝半導體晶圓的兩面方向延伸之龜裂,成為半導體晶圓的分割的起點。然後,於半導體晶圓施加力,於前述改質層的部位分割半導體晶圓,製作半導體晶片。The so-called invisible cutting (registered trademark) is as follows. That is, first, a predetermined divided portion is set inside the semiconductor wafer, the portion is set as a focus, and laser light is irradiated to focus on the focus, thereby forming a modified layer inside the semiconductor wafer. Unlike other parts of the semiconductor wafer, the modified layer of the semiconductor wafer is modified by irradiation with laser light and becomes weaker in intensity. Therefore, when a force is exerted by the semiconductor wafer, cracks extending toward both surfaces of the semiconductor wafer are generated in the modified layer inside the semiconductor wafer, which become a starting point for dividing the semiconductor wafer. Then, force is applied to the semiconductor wafer, and the semiconductor wafer is divided at the portion of the modified layer to produce a semiconductor wafer.
如前文所說明,使用保護膜形成膜中相對於保護膜形成膜的總質量,填充材(D)的含量的比率為50質量%以上者作為保護膜形成膜13之情形時,具保護膜之半導體晶片913’之中,保護膜130’具有高的保護性能,半導體晶片90的保護功效高。例如,具保護膜之半導體晶片913’之中,碎屑得到抑制。As explained above, when the ratio of the content of the filler (D) in the protective film-forming film to the total mass of the protective film-forming film is 50% by mass or more as the protective film-forming film 13, it is necessary to have a protective film. Among the semiconductor wafers 913', the protective film 130' has high protective performance, and the semiconductor wafer 90 has a high protective effect. For example, in the semiconductor chip 913' with a protective film, debris is suppressed.
[拾取步驟] 製造方法(1)之前述加工步驟之後,前述拾取步驟之中,如圖4E所示,將具保護膜之半導體晶片913’自支撐片10扯離而加以拾取。 製造方法(1)的拾取步驟之中,在具保護膜之半導體晶片913’中之保護膜130’的第二面130b’與支撐片10中之黏著劑層12的第一面12a之間產生剝離。 [Pickup steps] After the aforementioned processing steps of the manufacturing method (1), during the aforementioned picking-up step, as shown in FIG. 4E, the semiconductor wafer 913' with the protective film is pulled away from the supporting sheet 10 and picked up. In the pick-up step of the manufacturing method (1), a gap is generated between the second surface 130b' of the protective film 130' in the semiconductor wafer 913' with a protective film and the first surface 12a of the adhesive layer 12 in the support sheet 10.

具保護膜之半導體晶片913’能夠以公知的方法進行拾取。 例如,製造方法(1)之中,能夠藉由將具保護膜之半導體晶片913’從支撐片10側經由(介設)支撐片10而使用銷頂起來進行拾取。圖4E係進而表示使用真空筒夾等扯離手段7,將具保護膜之半導體晶片913’於箭頭P方向進行扯離之情形。 The semiconductor wafer 913' with the protective film can be picked up by a known method. For example, in the manufacturing method (1), the semiconductor wafer 913' provided with the protective film can be picked up from the support sheet 10 side via (intermediately) the support sheet 10 using pins. FIG. 4E further shows the situation in which the semiconductor wafer 913' with the protective film is separated in the direction of arrow P using a separation means 7 such as a vacuum collet.
製造方法(1)之前述拾取步驟之後,例如藉由將所拾取之具保護膜之半導體晶片913’中之突狀電極以覆晶連接於基板的電路面,使具保護膜之半導體晶片913’接合於前述電路面(本說明書之中有時稱為「接合步驟」)。 前述突狀電極係設置於具保護膜之半導體晶片913’中之半導體晶片90的電路面90a。 接合步驟之中,例如能夠藉由使具保護膜之半導體晶片913’中之突狀電極接觸設置於基板的電路面之連接墊,而將前述突狀電極與前述電路面上之前述連接墊進行電性連接而覆晶連接。 具保護膜之半導體晶片913’對前述電路面之接合能夠以公知的方法進行。 After the aforementioned pickup step of the manufacturing method (1), for example, by flip-chip connecting the protruding electrodes in the picked up semiconductor wafer 913' with a protective film to the circuit surface of the substrate, the semiconductor wafer 913' with the protective film is Bonding to the aforementioned circuit surface (sometimes referred to as "bonding step" in this specification). The aforementioned protruding electrodes are provided on the circuit surface 90a of the semiconductor chip 90 in the semiconductor chip 913' having a protective film. In the bonding step, for example, the protruding electrodes in the semiconductor chip 913' with the protective film can be brought into contact with the connection pads provided on the circuit surface of the substrate, so that the protruding electrodes and the connection pads on the circuit surface can be connected. Electrical connection and flip chip connection. The semiconductor wafer 913' with the protective film can be bonded to the circuit surface by a known method.
前述接合步驟之後,藉由使用具備有具保護膜之半導體晶片913’之基板,以後依據公知的方法製作半導體封裝體,並使用該半導體封裝體,能夠製造目標之半導體裝置。After the above-mentioned bonding step, by using a substrate having a semiconductor wafer 913' with a protective film, a semiconductor package is produced according to a known method, and using the semiconductor package, a target semiconductor device can be manufactured.
至此為止,作為製造方法(1),說明了關於使用保護膜形成用複合片之情形的半導體裝置之製造方法,但即使替代保護膜形成用複合片而改為使用未構成保護膜形成用複合片之保護膜形成膜,仍可製造半導體裝置。 圖5A至圖5F係用以示意性地說明本實施形態之半導體裝置之製造方法之中,使用未構成保護膜形成用複合片之保護膜形成膜之情形之製造方法之一例(本說明書之中有時稱為「製造方法(2)」)之剖面圖。此處,對於使用圖1所示之保護膜形成膜13之情形加以說明。 So far, the manufacturing method of a semiconductor device using the composite sheet for forming a protective film has been described as the manufacturing method (1). However, even if the composite sheet for forming a protective film is used instead of the composite sheet for forming a protective film, a composite sheet that does not constitute a protective film forming composite sheet is used. The protective film is formed into a film, and semiconductor devices can still be manufactured. 5A to 5F are schematically illustrating an example of a manufacturing method in which a protective film-forming film that does not constitute the protective film-forming composite sheet is used in the manufacturing method of the semiconductor device according to this embodiment (in this specification Sometimes called "manufacturing method (2)") cross-sectional view.

This step is the same as the manufacturing method except that the protective film forming film 13 provided with the second release film 152 is used instead of the protective film forming composite sheet 101 (in other words, the protective film forming film 13 provided with the support sheet 10 ). (1) The attaching steps are the same as mentioned above.
保護膜形成膜13亦可在貼附於半導體晶圓9的內面9b之前預先裁斷成與半導體晶圓9相同直徑或小於晶圓的直徑1mm至10mm之直徑的圓形狀。藉由如此,在貼附步驟之作業性以及移除後述的第二剝離膜152的作業性提高。The protective film forming film 13 may be pre-cut into a circular shape having the same diameter as the semiconductor wafer 9 or a diameter 1 mm to 10 mm smaller than the diameter of the wafer 9 before being attached to the inner surface 9 b of the semiconductor wafer 9 . This improves the workability in the attaching step and the workability in removing the second release film 152 described below.
製造方法(2)中,藉由自保護膜形成膜13所製作之前述試片之上述在DSC之發熱起始溫度為160℃以上,貼附步驟之中,保護膜形成膜13對半導體晶圓9之貼附性良好。例如,即使使用以常溫保存後的保護膜形成膜13,保護膜形成膜13對半導體晶圓9之貼附性仍良好,因此,保護膜所帶來之半導體晶片的保護性能亦高。In the manufacturing method (2), the above-mentioned test piece produced by the self-protective film-forming film 13 has a heat starting temperature in DSC of 160° C. or above. During the attachment step, the protective film-forming film 13 has no contact with the semiconductor wafer. 9. Good adhesion. For example, even if the protective film-forming film 13 stored at normal temperature is used, the adhesion of the protective film-forming film 13 to the semiconductor wafer 9 is still good. Therefore, the protective performance of the semiconductor wafer provided by the protective film is also high.

In the thus newly generated The exposed surface (that is, the second surface 13b' of the protective film 13') is irradiated with laser light R, and laser printing is performed on the surface. The semiconductor wafer 901' with a protective film after laser printing is the same as the semiconductor wafer 901' with a protective film after laser printing in the manufacturing method (1). In this step, laser printing can be performed on the protective film 13' in the same manner as in the aforementioned printing step of the manufacturing method (1).

At this time, the silicon wafer among the silicon wafers with the protective film is made to face the flat surface of the table. The surface on the silicon wafer side of the silicon wafer with the protective film becomes a convex surface when the silicon wafer with the protective film is warped. Then, the distance between the flat surface of the table and the silicon wafer with protective film is measured at three arbitrary locations on the outer periphery of the silicon wafer with protective film, and the average value is used as the warpage of the silicon wafer with protective film. quantity. Furthermore, based on the following criteria, the effect of suppressing warpage of the silicon wafer provided with the protective film was evaluated. The results are shown in Table 1. (evaluation criteria) A: The amount of warpage is 0mm, and warpage is suppressed. B: The amount of warpage is between more than 0 mm and less than 2 mm. The effect of inhibiting warpage is worse than A, but the protective film forming film can be used in practice. C: The amount of warpage exceeds 2 mm, the effect of suppressing warpage is low, and the protective film forming film cannot be used for actual use. Here, the protective film-forming film is ready for actual use, which means that after the protective film-forming film is thermally cured (after the protective film is formed), for example, a dicing sheet can be attached without any problem, and semiconductor wafers with a protective film can be processed.

Then, the effectiveness of suppressing debris on the silicon wafer with the protective film was evaluated based on the maximum value based on the following criteria. The results are shown in Table 1. (evaluation criteria) A: The maximum value of debris is 20 μm or less, and the debris suppression effect is high. B: The maximum value of debris exceeds 20 μm and is less than 50 μm, which is worse than A but debris is suppressed. C: The maximum value of debris exceeds 50 μm, and debris is not suppressed.
[保護膜形成膜之製造以及評價] [實施例2至實施例6、比較例1至比較例2] 除了保護膜形成膜的含有成分與含量以成為表1或表2所示的方式變更調配成分的種類以及量中任一者或兩者的方面以外,以與實施例1之情形相同方法製造保護膜形成膜並進行評價。結果如表1或表2所示。 [Production and evaluation of protective film forming films] [Example 2 to Example 6, Comparative Example 1 to Comparative Example 2] A protective film-forming film was produced in the same manner as in Example 1, except that any one or both of the types and amounts of the ingredients were changed as shown in Table 1 or Table 2. Films were formed and evaluated. The results are shown in Table 1 or Table 2.
[表1]

由上述結果可明顯看出,於實施例1至實施例6之中,保護膜形成膜對矽晶圓之貼附性良好,確認到保護膜形成膜的常溫之保存穩定性高。在實施例1至實施例6之中,在DSC法之試片的發熱起始溫度為170.6℃以上而充分地高。It is apparent from the above results that in Examples 1 to 6, the protective film-forming film has good adhesion to the silicon wafer, and it is confirmed that the protective film-forming film has high storage stability at room temperature. Among Examples 1 to 6, the heat generation onset temperature of the test piece in the DSC method was 170.6° C. or higher, which was sufficiently high.
進而,在實施例1至實施例6之中,抑制在具保護膜之矽晶圓之翹曲的功效與抑制在具保護膜之矽晶片之碎屑的功效皆良好,保護膜形成膜具有良好的特性。 其中,在實施例1、實施例2、實施例5、實施例6之中,抑制在具保護膜之矽晶圓之翹曲的功效與抑制在具保護膜之矽晶片之碎屑的功效皆特別優異,保護膜形成膜具有特別優異的特性。實施例1、實施例2、實施例5、實施例6之中,保護膜形成膜中,相對於保護膜形成膜的總質量,填充材(D)的含量的比率在50質量%至63質量%的範圍內。 Furthermore, in Examples 1 to 6, the effect of suppressing the warpage of the silicon wafer with the protective film and the effect of suppressing the chipping of the silicon wafer with the protective film are both good, and the protective film forming film has good characteristics. Among them, in Example 1, Example 2, Example 5, and Example 6, the effect of suppressing the warpage of the silicon wafer with the protective film and the effect of suppressing the chipping of the silicon wafer with the protective film are both. Particularly excellent, the protective film-forming film has particularly excellent properties. In Example 1, Example 2, Example 5, and Example 6, in the protective film-forming film, the content ratio of the filler (D) in the protective film-forming film is from 50 mass % to 63 mass % relative to the total mass of the protective film-forming film. within the range of %.
相對於此,比較例1至比較例2之中,保護膜形成膜對矽晶圓之貼附性差,保護膜形成膜在常溫之保存穩定性差。特別在比較例2之中,保護膜形成膜在常溫之保存穩定性低。比較例1至比較例2之中,在DSC法之試片的發熱起始溫度為150℃以下而不充分。 比較例1至比較例2之中,由於無法將保護膜形成膜正常地貼附至矽晶圓,故未對於抑制在具保護膜之矽晶圓之翹曲的功效以及抑制在具保護膜之矽晶片之碎屑的功效進行評價。 [產業可利用性] In contrast, in Comparative Examples 1 to 2, the adhesion of the protective film-forming film to the silicon wafer was poor, and the storage stability of the protective film-forming film at room temperature was poor. Especially in Comparative Example 2, the storage stability of the protective film-forming film at normal temperature was low. In Comparative Examples 1 to 2, the heat generation starting temperature of the test piece in the DSC method was 150° C. or lower, which was insufficient. In Comparative Examples 1 to 2, since the protective film-forming film cannot be attached to the silicon wafer normally, the effect of suppressing the warpage of the silicon wafer with the protective film and the effect of suppressing the warpage of the silicon wafer with the protective film are not evaluated. Evaluate the efficacy of silicon wafer chips. [Industrial Availability]
