Abstract
【解決手段】 半導体基板上に設けられ、第1の銅配線領域と第1の銅配線領域内に設けられた第1の層内絶縁領域を有する第1のパッド層と、第1のパッド層上に層間絶縁膜を介して設けられ、第2の銅配線領域と第2の銅配線領域内に設けられた第2の層内絶縁領域を有する第2のパッド層とを少なくとも有する多層パッドを備え、第1及び第2のパッド層において、第1の銅配線領域、第1の層内絶縁領域、第2の銅配線領域及び第2の層内絶縁領域が、半導体基板に対する垂直上方から多層パッドを透過的に見た場合、多層パッドに銅配線により覆われない領域が生じないようにレイアウトされる。

Description
図1は従来の形態における銅配線を有するパッド層を含む多層パッド構造を模式的に示した図であり、図1(a)は断面図、図1(b)は銅パッド層(単層)の平面図である。パッド領域のみを図示し、内部回路領域については図示を省略している。図中、11は半導体基板、12はパッド層、13はパッド層を構成する配線領域、14は配線領域13内に設けられた層内絶縁領域、15は層間絶縁膜、16は層間絶縁膜中に設けられたビア、17はカバー膜である。
図3(a)に示したように、第1の実施の形態における多層パッド構造は半導体基板31上に複数のパッド層32をシリコン酸化膜からなる層間絶縁膜35を介して積層することにより構成される。層間絶縁膜35上にはカバー膜37が形成される。パッド層32上にはカバー膜37は形成されず、開口部が形成される。開口部で露出するパッド層の最上層32aには、組み立て工程でワイヤボンディングにより導線が接続されるとともに、半導体装置の電気的特性を検査するための試験工程ではプローブ針が接触される。
