Abstract
Description
ケイ素ウェハーのような基板上の、並びに電子部品用途に有用なその他の基板上に印刷されるパッドは、ダイ付着接着剤として用いられ得る。パッドは、基板、別のダイ又はその他の電子部品に半導体ダイを結合するために用いられ得る。例えばプラズマ処理又は化学蒸着といった方法により、パッドが接着のために活性化される場合、接着を生成するか又は改良するためのパッド物質の後硬化(post-cure)表面処理のために、これが適用され得る。しかしながらこれらの方法は、パッドの上面が平坦でないことがあるという欠点を蒙り得る。エッジヒル(edgehill)のような欠陥が存在し得る。パッドの上面が欠陥を有する場合、欠陥は結合表面間の不完全な接触を引き起こし、その結果不十分な接着を生じ得る。したがって、平坦な上面を有するパッドを提供する方法が電子部品産業において引き続き必要とされている。
理論に制約はされたくないが、印刷工程で用いられる慣用的スクリーン又はステンシルのような、蒸着ツール中の開口部の側壁と、基板上に蒸着される組成物との間の相互作用のため、基板上のパッドの形成中にエッジヒルが生成すると考えられる。この相互作用は、開口部の側壁の全部又は一部の近くに蒸着される組成物の高さを、開口部の残余部を通して(through)蒸着された組成物の高さより大きくさせ、それにより、その結果生じる堆積物の外辺部の少なくとも一部の周辺にエッジヒルを形成する。エッジヒルは、堆積物を硬化させることにより、パッドの上面への平坦基板の接着に有害作用を及ぼし得る。
本発明は、エッジヒルを低減し、且つ平坦な上面を有するパッドを製造する方法に関する。平坦な上面を有するパッドの製造方法は、a)第一基板上に組成物の平坦な上面を有する堆積物を塗布すること、並びにb)平坦な上面を有する堆積物を硬化させること、を包含する。この方法は、c)平坦な上面を有する堆積物の上面に第二基板を接着すること、及び、任意にd)過程a)、b)及びc)を反復すること、をさらに包含し得る。
量、パーセンテージ及び比はすべて、別記しない限り、重量単位である。以下は、本明細書中で用いる場合の定義の一覧である。
「エッジヒル」とは、物質の外辺部の少なくとも一部の周辺の領域であって、物質の残余部より大きい高さを有する領域を意味する。
本発明は、平坦な上面を有するパッドを製造する方法に関する。この方法は、
a)第一基板上に組成物の平坦な上面を有する堆積物を塗布すること、
b)平坦な上面を有する堆積物を硬化させること、
c)平坦な上面を有する堆積物の上面に第二基板を接着すること、及び
d)過程a)、b)及びc)を任意に反復すること
を包含する。
a)第一電子基板上に硬化性シリコーン組成物の平坦な上面を有する堆積物をステンシル印刷することであって、
第一電子基板が半導体ダイ又は半導体ダイ取り付け部材から選択され、
平坦な上面を有する堆積物のステンシル印刷がダウンステップステンシルを通したスクイジー(squeegee)により行われる、
ステンシル印刷することと、
b)平坦な上面を有するパッドを形成するために、平坦な上面を有する堆積物を硬化させることと、
任意に、c)半導体ダイ又は半導体ダイ取り付け部材から選択される第二電子基板を、平坦な上面を有する堆積物の上面に接着することと、
任意に、d)過程a)、b)及びc)を反復することと
を包含する方法により作製され得る。硬化性シリコーン組成物は、硬化して例えばダイ付着接着剤を形成し得る。
上記の方法に用いるのに適した組成物は、任意の便利なホットメルト接着性組成物又は硬化性組成物であり得る。適切な硬化性組成物としては、硬化性シリコーン組成物、硬化性シリコーン有機組成物及び硬化性有機組成物が挙げられる。硬化性シリコーン組成物は、例えばヒドロシリル化反応又は縮合(condensation)反応により硬化可能であり得る。適切な硬化性シリコーン有機組成物としては、シリコーン−フェノール組成物及びシリコーン−エポキシ組成物が挙げられる。適切な硬化性有機組成物は、エポキシ組成物により例示される。適切な硬化性組成物は、例えば熱、湿気、紫外線、マイクロ波、電子線、酸素又はそれらの組合せへの曝露により硬化可能であり得る。上記の方法で用いるための適切な組成物は、ダイ付着接着剤組成物であり得る。ダイ付着接着剤組成物は、硬化してシリコーンダイ付着接着剤を生成する硬化性シリコーン組成物、硬化してシリコーン有機ダイ付着接着剤を生成する硬化性シリコーン有機組成物、又は硬化して有機ダイ付着接着剤を生成する硬化性有機組成物を含み得る。適切な硬化性シリコーン組成物としては、公開番号2003/0145940を有する、2001年10月9日付けで出願された米国特許出願第09/973498号明細書におけるダイ付着接着剤組成物、並びに、A)1分子当たり平均で少なくとも2つの脂肪族系不飽和有機基を含有するポリオルガノシロキサンと、B)1分子当たり平均で少なくとも2つのケイ素結合水素原子を含有するポリオルガノ水素シロキサンと、C)ヒドロシリル化反応触媒とを含むその他のヒドロシリル化硬化性シリコーン組成物が挙げられるが、これらに限定されない。組成物は、ダイ付着接着剤中に用いるのに適した1つ又は複数の任意の構成成分、例えばD)硬化修飾剤、E)充填剤、F)充填剤のための処理剤、G)スペーサー、H)接着促進剤、I)顔料、J)レオロジー修飾剤、K)空隙低減剤、及びL)溶媒をさらに含み得る。
構成成分(A)は、1分子当たり平均で少なくとも2つの不飽和有機基を有するポリオルガノシロキサンである。構成成分(A)は、線状、分岐状又は樹脂性構造を有し得る。構成成分(A)は、ホモポリマー又はコポリマーであり得る。不飽和有機基は2〜12個の炭素原子を有するアルケニル基であってもよく、例としてはビニル、アリル、ブテニル及びヘキセニルが挙げられるが、これらに限定されない。不飽和有機基は2〜12個の炭素原子を有するアルキニル基であってもよく、例としてはエチニル、プロピニル及びブチニルが挙げられるが、これらに限定されない。あるいは、不飽和有機基はアクリレート官能基又はメタクリレート官能基を含有してもよく、例としてはアクリロイルオキシアルキル、例えばアクリロイルオキシプロピル及びメタクリロイルオキシアルキル、例えばメタクリロイルオキシプロピルが挙げられるが、これらに限定されない。構成成分(A)中の不飽和有機基は、末端基位置、中間(pendant)位置又は末端基位置及び側基位置の両方に位置し得る。
