摘要

A semiconductor device including a first material layer adjacent to a second material layer, a first via passing through the first material layer and extending into the second material layer, and a second via extending into the first material layer, where along a common cross section parallel to an interface between the two material layers, the first via has a cross section larger than that of the second via.
