(B)積層体20における接着剤層3及び保護フィルム5を型抜きすることによって、キャリアフィルム1上にキャリアフィルム1の長手方向に並ぶように配置された複数の接着剤片3pを得る工程。
次に、接着フィルム10の使用方法について説明する。図7はキャリアフィルム1から接着剤片3p及びこれを覆う保護部材5pをピックアップされる様子を模式的に示す断面図である。接着フィルム10に一定の張力を付与した状態で、くさび状部材60に接着フィルム10のキャリアフィルム1側の面を当接させながら、図7に示す矢印の方向に接着フィルム10を移動させる。これにより、同図に示すように、接着剤片3p及び保護部材5pの前方がキャリアフィルム1から浮いた状態となる。この状態のときに、例えば、吸引力を有するピックアップ装置65で接着剤片3p及び保護部材5pをピックアップする。例えば、ピックアップ装置65として、保護部材5pを視認するカメラ等を備えたものを使用することで、接着剤片3p及び保護部材5pの有無、並びに、向き等の情報を把握することが可能である。これらの情報に基づいて、その後の接着工程を適切に実施することができる。
図8は接着剤片3pを使用して製造された半導体装置の一例を模式的に示す断面図である。同図に示す半導体装置100は、半導体チップSと、半導体チップSが電気的に接続された基板50と、半導体チップSと基板50との間に配置されており、半導体チップSと基板50とを接着する接着剤片3pとを備える。半導体チップSの形状は、例えば、長方形又は正方形であるのに対して接着剤片3pの形状はT字型であり、半導体チップSの形状と接着剤片3pの形状が異なっている。かかる構成を採用することにより、図4に示したとおり、領域R1,R2において基板50と半導体チップSを導電材料A1,A2によって電気的に接続することが可能である。

(1)接着剤片の面積率R
表1に示す接着剤片の面積A(mm2)、ピッチP(mm)及びキャリアフィルムの幅W(mm)を下記式に代入し、接着剤片の面積率R(%)を算出した。
面積率R(%)=A/(P×W)×100
キャリアフィルム上に接着剤片及びこれを覆う保護部材が設けられている領域の波長500nmの光の透過率を日本分光株式会社製のV-570(商品名)を使用して測定した。
型抜きを行っていない積層フィルム(キャリアフィルム/接着剤層/保護フィルム)を20mm幅に切り出した。両面テープを用い、キャリアフィルム側の面をアルミニウム板に貼り付けた後、保護フィルムを剥がした。その後、キャリアフィルムに対する接着剤層の角度を90°に維持しながら、接着剤層を上方に引き上げることによってキャリアフィルムから接着剤層を剥離させた。引き上げ速度は50mm/分とし、測定環境温度は23±2℃とした。引き上げに要する力を測定した。この測定値(mN)及び試料の幅(20mm)を下記式に代入することによって、キャリアフィルムと接着剤層と間の密着力を算出した。
密着力(N/m)=測定値(mN)/20(mm)
