Definitions
- the present invention relates to a photosensitive resin composition, and a film adhesive, an adhesive sheet, an adhesive pattern, a semiconductor wafer with an adhesive layer, and a semiconductor device using the same.
- an adhesive is used to bond the semiconductor chip and the semiconductor chip mounting support member.
- This adhesive usually requires properties such as adhesiveness, thermocompression bonding, heat resistance, and moisture resistance, and when it is used in the form of a film, it needs to be stickable.
- Photosensitivity is a function in which a portion irradiated with light is chemically changed and insolubilized or solubilized in an aqueous solution or an organic solvent.
- a high-definition adhesive pattern can be formed by performing exposure and development processing through a photomask, and the formed adhesive pattern is deposited. It will have thermocompression bonding to the body.
- photosensitive adhesive compositions include those based on photoresists, polyimide resin precursors (polyamic acid) (for example, Patent Documents 1 and 2), and those based on low Tg polyimide resins. (Patent Document 3). From the viewpoint of working environment, wastewater treatment, etc., those that can be patterned with an alkaline developer are the mainstream.
- JP 2000-290501 A Japanese Patent Laid-Open No. 11-24257 International Publication No. 07/004569 Japanese Patent No. 3999840
- the film-like adhesive can easily give an optimum amount of resin by adjusting the thickness of the film, but requires a step of attaching a film-like adhesive called a temporary press-bonding step to the substrate.
- the temporary pressure bonding process prepares a film-like adhesive wound on a reel that is slit to a width larger than the chip width to be bonded, and the film-like adhesive on the substrate according to the chip size And thermocompression-bonded onto the substrate at a temperature at which the resin does not react.
- the film adhesive to be attached by temporary pressure bonding is made larger than the chip size. Therefore, there is a problem that it is necessary to provide a margin for the distance from the adjacent portion, and it is difficult to cope with high-density mounting.
- a method of forming an adhesive layer by a wafer process has attracted attention.
- a flat film forming property that does not depend on the steps derived from the circuit, a uniform and highly accurate pattern processing property, and a rewiring process. It is necessary to have adaptability to a connection terminal formation process, a dicing process, and the like.

得られた積層体を、接着シート側から、高精度平行露光機(オーク製作所製、商品名:EXM-1172-B-∞)によって1000mJ/cm2で露光し、80℃のホットプレート上で30秒間加熱した。基材(PETフィルム)を剥離除去した後、コンベア現像機(ヤコー社製)を用いて、テトラメチルアンモニウムヒドロキシド(TMAH)2.38質量%溶液を現像液とし、温度26℃、スプレー圧0.18MPaの条件でスプレー現像した後、温度25℃の純水にてスプレー圧0.02MPaの条件で6分間水洗し、120℃で1分間乾燥させた。このようにして、シリコンウェハ上に、感光性樹脂組成物の硬化物からなる硬化物層を形成した。
上記高温接着性の評価試験と同様にして、シリコンウェハ上に接着シートを積層した。得られた積層体を、接着シート側から、ネガ型パターン用マスク(日立化成社製、商品名:No.G-2)を介して、上記試験と同様に露光した。次いで、上記試験と同様に、ホットプレート上で放置後、基材を除去し、現像、水洗及び乾燥を行った。このようにして、シリコンウェハ上に、感光性樹脂組成物から得られる接着剤パターンを形成した。
パターン形成性の評価試験と同様にして、シリコンウェハ上に接着シートを積層した。この状態で室温下、2週間放置してからパターン形成性の評価試験と同様にして、シリコンウェハ上に、感光性樹脂組成物の接着剤パターンの形成を試みた。このとき形成された接着剤パターンを目視にて観察し、パターン形成性の評価試験と同様に、ライン幅/スペース幅=30μm/30μm以下の細線パターンが形成されていた場合をA、30μm/30μm超60μm/60μm以下の細線パターンが形成されていた場合をB、60μm/60μm超400μm/400μm以下の細線パターンが形成されていた場合をC、パターンが形成されていなかった場合をDとして、パターン形成性の評価を行った。評価結果を表2及び表4に示す。
上記高温接着性の評価試験と同様にして、シリコンウェハ及び硬化物層からなる積層体を、5mm×5mmの大きさに個片化した。ガラス基板の代わりにプリント基板(ガラスエポキシ基板 15mm×15mm×0.15mm)を用いて、個片化したシリコンチップ、接着剤パターン及びプリント基板からなり、これらがこの順に積層する積層体のサンプルを得た。得られたサンプルを、オーブン中で180℃、3時間の条件で加熱した。加熱後のサンプルを、温度85℃、湿度60%の条件下で168時間処理した後、温度25℃、湿度50%の環境下に置いた後、250℃、10秒のIR(赤外線)リフローを行い、剥離の有無を外観観察及び超音波探査装置(SAT)で観察した。全く剥離が見られなかったものをA、外観観察でははっきりとは剥離が見られないがSAT撮像により剥離が見られたものをB、外観観察で明らかな剥離が見られたものをCとして、耐リフロー性の評価を行った。評価結果を表2及び表4に示す。
支持台上に接続端子付きシリコンチップ(1cm×1cm、厚さ400μm、端子部は40μm×40μm、高さ40μm、100μmピッチでチップのペリフェラル部に沿って2列等間隔に存在)を載せ、その上に、上記接着シートを、接着剤層がシリコンウェハの端子側と接するように、真空ラミネーター(温度80℃、圧力0.5MPa、時間30秒)によってラミネートした。基材(PETフィルム)を剥離除去した後、露出した接着剤層の外観を光学顕微鏡により観察し、ボイドの発生なくラミネートできたか確認した。端子周囲にボイドの発生のない良好なものをA、端子周辺部にのみボイドが観察されたものをB、端子周囲のみならず全面に顕著なボイドが観察されたものをC(不可)とした。
支持台上にテフロン(登録商標)シートを載せ、その上に、上記接着シートを、ロール加圧(温度60℃、線圧39.2N/cm(4kgf/cm)、送り速度0.5m/分)によって積層した。得られた積層体を、基材付き接着シート側から、高精度平行露光機(オーク製作所製、商品名:EXM-1172-B-∞)によって1000mJ/cm2で露光し、80℃のホットプレート上で30秒間加熱した。接着剤層から基材(PETフィルム)を剥離除去した後、コンベア現像機(ヤコー社製)を用いて、テトラメチルアンモニウムヒドロキシド(TMAH)2.38質量%溶液を現像液とし、温度26℃、スプレー圧0.18MPaの条件で1分間接着剤層を現像液に晒した後、温度25℃の純水にてスプレー圧0.02MPaの条件で6分間水洗した。得られたフィルムをホットプレート上で、120℃で10分間乾燥させた後、厚さが80μmとなるようにロール加圧(温度100℃、線圧39.2N/cm(4kgf/cm)、送り速度0.5m/分)によって積層した。繰り返し積層する際は、片側のテフロン(登録商標)シートを剥離除去して、接着剤層同士が積層するように行った。これにより、テフロン(登録商標)シート、接着剤層及びテフロン(登録商標)シートからなる、積層体のサンプルを得た。片側のテフロン(登録商標)シートを剥離除去した後、オーブン中で180℃、3時間の条件で加熱した。加熱後のサンプルを、5mm幅の短冊状に切断し、もう一方のテフロン(登録商標)シートを剥離した後に、粘弾性アナライザー(レオメトリックス社製、商品名:RSA-2)を用いて、昇温速度5℃/min、周波数1Hz、測定温度-50℃~300℃の条件で測定し、得られたtanδピーク温度をTgとした。評価結果を表2及び表4に示す。
