Description
図1は、本発明の実施の形態1に係る半導体装置の製造方法を説明するための断面図である。
図4は、本発明の実施の形態2に係る半導体装置の製造方法を説明するための断面図である。本実施の形態では、シリコンウエハ1の外周部においてシリコン酸化膜2に段差9を形成し、この段差9を形成したシリコン酸化膜2上にアルミニウム配線層3を形成する。これにより、アルミニウム配線層3の表面にも段差が形成されるため、表面保護膜5とアルミニウム配線層3の接触面積が大きくなって密着性が更に向上する。
図5は、本発明の実施の形態3に係る半導体装置の製造方法を説明するための断面図である。本実施の形態では、シリコンウエハ1の外周部においてシリコンウエハ1の表面に段差10を形成し、段差10を形成したシリコンウエハ1の表面にアルミニウム配線層3を形成する。これにより、アルミニウム配線層3の表面にも段差が形成されるため、表面保護膜5とアルミニウム配線層3の接触面積が大きくなって密着性が更に向上する。
図6は、本発明の実施の形態4に係る半導体装置の製造方法を説明するための断面図である。本実施の形態では、シリコンウエハ1の外周部のアルミニウム配線層3上に、アルミニウム配線層3に比べて表面保護膜5に対する密着性が高い密着性強化膜11を形成する。そして、密着性強化膜11を覆うように表面保護膜5を形成し、密着性強化膜11と表面保護膜5が密着する。このように密着性強化膜11を設けたことによりシリコンウエハ1の外周部において表面保護膜5との密着性が更に向上する。
