Abstract
【解決手段】第1の半導体チップ40は、支持基板12に搭載されてワイヤボンディングされる。第2の半導体チップ64は支持材料60へと押圧されて、支持材料60をスペーサ50に隣接した、第1の半導体チップ40と第2の半導体チップ64との間の領域へと圧入する。これに代えて、支持材料60は、第1の半導体チップ40上に配置されて、ダイ装着材料62がスペーサ50上に配置される。第2の半導体チップ64はダイ装着材料62および支持材料60へと押圧されて、スペーサ端縁53,55を越えるように支持材料60の一部を押込む。ワイヤボンドが、支持基板12と、第1半導体チップ40および第2半導体チップ64との間に形成される。

Description
この発明は一般的に半導体部品に関し、より特定的には、マルチチップモジュールを含む半導体部品に関する。
より高速で、より安価で、より効率的な半導体部品に対する欲求は、半導体チップにおいて作製されるデバイスのサイズを縮小し、かつ、多数の半導体チップを典型的にはマルチチップモジュールと呼ばれる単一のパッケージ内に配置するように、半導体部品製造業者を動機付けた。マルチチップモジュール内の半導体チップは、水平方向の配向で、すなわち互いの横に、または垂直方向の配向で、すなわち互いの上に垂直に積層させて配置することができる。従来の垂直に積層されたマルチチップモジュールにおいては、第1の半導体チップが、接着剤によるボンディングによって回路基板に装着され、その後、半導体チップ上のボンディングパッドが半導体基板上の対応のボンディングパッドにワイヤボンディングされる。スペーサが第1の半導体チップ上に形成されるかまたは装着され、第2の半導体チップがスペーサに装着される。次いで、第2の半導体チップ上のボンディングパッドが、たとえばワイヤボンディングプロセスを用いて、半導体基板上の対応のボンディングパッドに結合される。スペーサは、ワイヤボンディングプロセスに適応するために、第1の半導体チップよりも小さくなければならない。さらに、スペーサは第2の半導体チップよりも典型的には小さい。この種の構造の欠点は、第2の半導体チップの、スペーサの上に張出す部分が、しなりやすいかまたは弾性があることである。こうして、第2の半導体チップの張出し部分上にあるボンディングパッドが回路基板上の対応のボンディングパッドにワイヤボンディングされる場合に、第2の半導体チップの張出し部分のしなりやすさが、第2の半導体チップ上のボンディングパッドに形成される接合材を弱くすることである。この接合材の弱化は、デバイスの壊損を引起す。
この発明は、マルチチップモジュールおよびマルチチップモジュールを製造するための方法を提供することにより、上述の必要性を満足する。一実施例に従うと、この発明は、第1および第2の主表面を有する支持基板を設けるステップを含み、支持基板は、チップ受入領域と複数のボンディングパッドとを有する。第1の半導体チップはチップ受入領域に結合され、第1の半導体チップは複数のボンディングパッドを有する。第1の半導体チップの第1のボンディングパッドは、支持基板の第1のボンディングパッドに結合される。スペーサは、第1の半導体チップの一部に結合される。支持材料は、スペーサと第1の半導体チップとのうちの少なくとも1つの上に配置される。第2の半導体チップは、支持材料上に位置決めされ、第2の半導体チップは、第1の主表面と複数のボンディングパッドとを有する。第2の半導体チップの第1のボンディングパッドは、支持基板の第2のボンディングパッドに結合される。
この発明は一般的に、マルチチップモジュールおよびマルチチップモジュールを製造するための方法を提供するが、ここではマルチチップモジュールの半導体チップが垂直に積層される。マルチチップモジュールの半導体チップを垂直に積層する際に、ワイヤボンドのための隙間ができるように、半導体チップの間にスペーサが挿入される。スペーサの上方に位置する半導体チップの一部が、スペーサの端縁の上に張出す。スペーサの上に張出す半導体チップの部分はしなりやすい。しなりやすさは一般的に半導体チップの脆弱性を増大させるが、脆弱性の増大は、約0.6ミリメートル(mm)未満の厚さを有する半導体チップにおいてより顕著である。このしなりやすさはワイヤボンディングプロセスの間に半導体チップを振動させ、これにより半導体チップ上のボンディングパッドにボンディングされたワイヤが破壊される。この発明に従うと、スペーサの上に張出す第2の半導体チップの部分下に支持材料を形成することにより、この振動が軽減される。支持材料は、半導体チップに付加的な剛性を与え、この剛性が半導体チップの張出し部分の振動を減少させ、かつワイヤボンドの信頼性を向上させる。
