摘要:
A method for making a semiconductor device is described. That method comprises forming a first dielectric layer on a substrate, then forming a trench within the first dielectric layer. After forming a second dielectric layer on the substrate, a first metal layer is formed within the trench on a first part of the second dielectric layer. A second metal layer is then formed on the first metal layer and on a second part of the second dielectric layer.

A complementary metal oxide semiconductor integrated circuit may be formed with a PMOS device formed using a replacement metal gate and a raised source drain. The raised source drain may be formed of epitaxially deposited silicon germanium material that is doped p-type. The replacement metal gate process results in a metal gate electrode and may involve the removal of a nitride etch stop layer.

A method for making a semiconductor device is described. That method comprises forming a dielectric layer on a substrate, forming a trench within the dielectric layer, and forming a high-k gate dielectric layer within the trench. After forming a first metal layer on the high-k gate dielectric layer, a second metal layer is formed on the first metal layer. At least part of the second metal layer is removed from above the dielectric layer using a polishing step, and additional material is removed from above the dielectric layer using an etch step.
