发明名称 Multi-Layer Metal Contacts
摘要 A method for forming metal contacts within a semiconductor device includes forming a first-layer contact into a first dielectric layer that surrounds at least one gate electrode, the first-layer contact extending to a doped region of an underlying substrate. The method further includes forming a second dielectric layer over the first dielectric layer and forming a second-layer contact extending through the second dielectric layer to the first-layer contact.

主权项 1. A method for forming metal contacts within a semiconductor device, the method comprising: forming a first-layer contact in a first dielectric layer that surrounds a gate electrode, the first-layer contact extending to a doped source/drain region of an underlying substrate; forming a second dielectric layer over the first dielectric layer; forming a second-layer contact extending through the second dielectric layer to the first-layer contact.
