Description
熱硬化性樹脂層は、他の部材(例えば、半導体チップ)に対して接着性を有するため、フィルムに接着剤層等を別途設けなくてもよい。なお、熱硬化性樹脂層、第一の熱硬化性樹脂層、及び第二の熱硬化性樹脂層の熱硬化後の剛性は、剛材層の剛性よりも低くても高くてもよい。また、剛材層は、熱硬化性樹脂層よりも高い剛性を有する樹脂剛材層又は熱硬化性樹脂層よりも高い剛性を有する金属層であってよい。剛材層は、例えば、ポリイミド樹脂層であってよい。
<第一実施形態>

(A)基材フィルム1と、粘着層2と、熱硬化性樹脂層を少なくとも有するフィルム原反Dとをこの順序で備える積層フィルム20を準備する工程(図3参照)
(B)フィルム原反Dを個片化することによって、粘着層2の表面上に複数フィルム片(フィルム10)を形成する工程(図4(b)、(c)参照)
(C)粘着層2からフィルム片(フィルム10)をピックアップする工程(図4(d)参照)
(A)工程は、積層フィルム20を準備する工程である。積層フィルム20は、基材フィルム1と、粘着層2と、熱硬化性樹脂層を少なくとも有するフィルム原反Dとを備える。基材フィルム1は、例えば、ポリエチレンテレフタレートフィルム(PETフィルム)であってよい。粘着層2は、パンチング等によって円形に形成されている(図3(a)参照)。粘着層2は、感圧型の粘着剤からなるものであっても、紫外線硬化型の粘着剤からなるものであってもよい。粘着層2が紫外線硬化型の粘着剤からなるものである場合、粘着層2は紫外線が照射されることによって粘着性が低下する性質を有する。フィルム原反Dは、パンチング等によって円形に形成されており、粘着層2よりも小さい直径を有する(図3(a)参照)。フィルム原反Dは、フィルム10と同様に、熱硬化性樹脂層を少なくとも有する構成であり、例えば、フィルム10A~10Cと同様の構成を有している。
(B)工程は、フィルム原反Dを個片化することによって、粘着層2の表面上に複数のフィルム片を形成する工程である。図4(a)に示されるように、積層フィルム20にダイシングリングDRを貼り付ける。すなわち、積層フィルム20の粘着層2にダイシングリングDRを貼り付け、ダイシングリングDRの内側にフィルム原反Dが配置された状態にする。フィルム原反Dをダイシングによって個片化する(図4(b)参照)。ダイシングには、ダイシングソーを用いたダイシング装置を使用することができる。これによって、フィルム原反Dから多数のフィルム片(フィルム10)が得られる。
(C)工程は、粘着層2からフィルム片(フィルム10)をピックアップする工程である。図4(c)に示されるように、基材フィルム1をエキスパンドすることで、フィルム片を互いに離間させる。次いで、図4(d)に示されるように、フィルム片を突き上げ治具42で突き上げることによって粘着層2からフィルム片を剥離させるとともに、吸引コレット44で吸引してフィルム片をピックアップする。なお、ダイシング前のフィルム原反D又はピックアップ前のフィルム片を加熱することによって、熱硬化性樹脂層の硬化反応を進行させておいてもよい。ピックアップする際にフィルム片が適度に硬化していることで優れたピックアップ性を達成し得る。
(D)基板12上に半導体チップ11を配置する工程
(E)半導体チップ11の表面S1に、熱硬化性樹脂層を少なくとも有するフィルム10を配置する工程
(F)半導体チップ11を封止材14で封止する工程(図1参照)
(D)工程は、基板12上に半導体チップ11を配置する工程である。例えば、まず、基板12上の所定の位置に接着用部材15を介して半導体チップ11を配置する。その後、半導体チップ11はワイヤ13で基板12と電気的に接続される。
(E)工程は、半導体チップ11の表面S1に、熱硬化性樹脂層を少なくとも有するフィルム10を配置する工程である。この工程を経て、図5に示される構造体100Aが得られる。構造体100Aは、基板12と、基板12の表面上に配置された半導体チップ11と、半導体チップ11の表面S1上に配置されたフィルム10とを備える。フィルム10の配置は、例えば、圧着処理によって行うことができる。圧着処理は、例えば、80~180℃、0.01~0.50MPaの条件で、0.5~3.0秒にわたって実施することができる。なお、フィルム10に含まれる熱硬化性樹脂層は、(F)工程の開始前の時点で完全硬化してフィルムの硬化物10cとなっていることが好ましい。フィルムの硬化物10cは、フィルム10を、例えば、80~180℃、0.01~1.0MPaの条件で、1時間以上熱圧着することによって得ることができる。
(F)工程は、半導体チップ11を封止材14で封止する工程である。この工程を経て、図1に示される半導体装置100を得ることができる。
