Abstract:
A wiring structure for a semiconductor device includes a multilayer metallization having a total thickness of at least 5 μm and an interlayer disposed in the multilayer metallization with a first side of the interlayer adjoining one layer of the multilayer metallization and a second opposing side of the interlayer adjoining a different layer of the multilayer metallization. The interlayer includes at least one of W, WTi, Ta, TaN, TiW, and TiN or other suitable compound metal or a metal silicide such as WSi, MoSi, TiSi, and TaSi.
