Abstract
【解決手段】表面側に下層配線9が設けられたSiO2層4上に、保護膜10と第1絶縁膜11および第2絶縁膜12とを順次形成する。次に、下層配線9上の第1絶縁膜11および第2絶縁膜12に、保護膜10に達する接続孔16と接続孔16の上部に連通する配線溝17を形成する。次いで、接続孔16の底部に保護膜10を残存させた状態で、第1の熱処理を行う。続いて、保護膜10を除去し、接続孔16の底部に下層配線9を露出させる。次に、接続孔16の底部に下層配線9を露出させた状態で、第1の熱処理よりも低い温度で第2の熱処理を行う。その後、接続孔16および配線溝17にヴィアおよび配線を形成することを特徴とする半導体装置の製造方法である。
