Description
薄化前の半導体ウエハー(ここでは単にウエハーとも呼ぶ)を、研磨装置で研磨するために支持体に接着される。その際の接着は研磨後に容易に剥離されなければならないため、仮接着と呼ばれる。この仮接着は支持体から容易に取り外されなければならず、取り外しに大きな力を加えると薄化された半導体ウエハーは、切断されたり変形することがあり、その様なことが生じない様に、容易に取り外される。しかし、半導体ウエハーの裏面研磨時に研磨応力によって外れたりずれたりすることは好ましくない。従って、仮接着に求められる性能は研磨時の応力に耐え、研磨後に容易に取り外されることである。

ウエハーの回路面の反対側の加工とは、研磨によるウエハーの薄化が行われる。その後、シリコン貫通電極(TSV)等の形成を行い、その後に支持体から薄化ウエハーを剥離してウエハーの積層体を形成し、3次元実装化される。また、それに前後してウエハー裏面電極等の形成も行われる。ウエハーの薄化とTSVプロセスには支持体に接着された状態で250~350℃の熱が付加されるが、本発明に用いられる仮接着剤としての積層体はそれらの耐熱性を有している。
上記仮接着はウエハー裏面の研磨時は接着されていて、ウエハー裏面の研磨後には支持体と薄化されたウエハーが分離できるものである。
