INTERPOSER WAFER AND METHOD OF MANUFACTURING SAME |
摘要 |
In one embodiment, a method of manufacturing an interposer wafer includes forming a first hole having a first depth on a first main surface of a semiconductor wafer. The method further includes forming a second hole having a second depth on the first main surface of the semiconductor wafer before forming the first hole or after forming the first hole, the second depth being shallower than the first depth. The method further includes forming an electrode in the first hole. The method further includes forming an alignment mark in the second hole. |
