FinFET structure and method of manufacturing the same |
摘要 |
A semiconductor structure and a method for forming the same are provided. The method includes providing a substrate, forming a fin structure extruding from the substrate, forming shallow trench isolations over the substrate, and forming an oxide material over the fin structure. The method further includes forming a carbon-doped amorphous silicon layer or a carbon-doped poly silicon layer over the oxide material, wherein the forming a carbon-doped amorphous silicon layer or a carbon-doped poly silicon layer includes doping carbon in a range of from about 5E19/cm3 to about 1E22/cm3. |
