发明名称 Thin gate electrode CMOS devices and methods of fabricating same
摘要 A CMOS device and method of forming the CMOS device. The device including a source and a drain formed in a semiconductor substrate, the source and the drain and separated by a channel region of the substrate; a gate dielectric formed on a top surface of the substrate and a very thin metal or metal alloy gate electrode formed on a top surface of the gate dielectric layer, a polysilicon line abutting and in electrical contact with the gate electrode, the polysilicon line thicker than the gate electrode. The method including, forming the gate electrode by forming a trench above the channel region and depositing metal into the trench.
