Abstract
Description
図1は、第1の実施形態の半導体装置の製造方法を示す図である。デバイスウェハ10と支持ウェハ14が貼り合わされた半導体基板20を用意する(図1(A))。デバイスウェハ10と支持ウェハ14は、例えば、単結晶シリコン基板であり、それぞれ、例えば775μmの膜厚を有する。デバイスウェハ10と支持ウェハ14の間には、酸化シリコン膜12を有する。例えば、酸化シリコン膜12は支持ウェハ14の表面に形成された酸化シリコン膜である。酸化シリコン膜12の表面に水分子を吸着さる処理を行った後に両方のウェハ(10、14)を重ね合せて密着させ、熱処理を行うことにより、デバイスウェハ10と支持ウェハ14を貼り合せることが出来る。
図4は、第2の実施形態の半導体装置の製造方法を模式的に説明する為の図である。既述の実施形態に対応する構成要素には同一の符号を付している。本実施形態においては、中央部の膜厚が周縁部に比べてbだけ厚い支持ウェハ14が用いられる。支持ウェハ14とデバイスウェハ10が貼り合わされる。支持ウェハ14の中央部の膜厚が厚い為、結果として、貼り合わされた半導体基板20の中央部の厚みが厚くなる(図4(A))。
図6は、第3の実施形態の半導体装置の製造方法を模式的に説明する為の図である。既述の実施形態に対応する構成要素には同一の符号を付している。本実施形態においては、中央部の膜厚が周縁部に比べてcだけ薄い支持ウェハ14が用いられる。支持ウェハ14とデバイスウェハ10が貼り合わされた半導体基板20が用意される(図6(A))。
図8は、第4の実施形態の半導体装置の製造方法を説明する為の図である。本実施形態は、裏面照射型CMOSイメージセンサーの製造方法の一つの実施形態を示す。
