【発明の詳細な説明】 この発明は半導体基板をその支持体に取り付ける際にそ

た。又最近半導体装置の組立が自動化し、高速化するに
つれて、裏面の半田なじみ性が問題となり、組立機械の
中で半導体基板を放熱板にこすりつけながら組立てる方
式が一般的に行われている。しかしながらこの方法では
こすりつける為の時間がかかることや、こすりつける際
に半導体基板に歪を生じさせ、半田の酸化物をまき込む
といった不都合を生ずる場合もあった。
この為に半導体基板の裏面にあらかじめ半田を附着させ
ておけば、放熱板にこすりつけなくても半田なじみ性が
良く短時間に半田付けを完了させることができる。従来

てから半田を附着させており、１ｊ＠率が悪かったので
ごく一部の例を除いてはあまり行われなかった。
本発明は半導体ウェハーの状態であらかじめ半田を附着
させることをも可能にし、個々の半導体基板に切り出し
た際にもつながらず要易に分離することができる為の手
段を提供するものである。
半導体基板周囲にある高さを持った領域を°設は本こと
により、半田層の厚みを確保し、放熱板からの歪や、温
度サイクル等による熱的な歪に対しても有利とすること
ができる。
