发明名称 Semiconductor device and fabrication process thereof
摘要 A semiconductor device includes a substrate having first and second device regions separated from each other by a device isolation region, a first field effect transistor having a first polysilicon gate electrode and formed in the first device region, a second field effect transistor having a second polysilicon gate electrode and formed in the second device region, a polysilicon pattern extending over the device isolation region from the first polysilicon gate electrode to the second polysilicon gate electrode, and a silicide layer formed on a surface of the first polysilicon gate electrode, a surface of said the polysilicon gate electrode and a surface of the polysilicon pattern so as to extend on the polysilicon pattern from the first polysilicon gate electrode to the second polysilicon gate electrode, the silicide layer having a region of increased film thickness on the polysilicon pattern, wherein the silicide layer has a surface protruding upward in the region of increased film thickness.
