发明名称 METHOD OF FORMING WIRING LAYER OF SEMICONDUCTOR DEVICE
摘要 A method of forming a wiring layer of a semiconductor device, includes forming a first interlayer insulating layer to have a first thickness corresponding to a part of the thickness of an interlayer insulating layer that is to be formed on a support layer and forming a first contact plug in the first interlayer insulating layer. The method further includes forming a second interlayer insulating layer to have a second thickness on the first contact plug and the first interlayer insulating layer, thereby forming the interlayer insulating layer, wherein the second thickness corresponds to the rest of the thickness of the interlayer insulating layer, and forming a second contact plug connected to the first contact plug in the second interlayer insulating layer, thereby forming a local wiring layer including the first contact plug and the second contact plug.
