    摘要: A semiconductor device and method for fabricating the same. The semiconductor device comprises a substrate with a gate stack thereon, wherein the gate stack comprises a high-k dielectric layer and a conductive layer sequentially overlying a portion of the substrate. An oxidation-proof layer overlies sidewalls of the gate stack. A pair of insulating spacers oppositely overlies sidewalls of the gate stack and the oxidation-proof layers thereon and a pair of source/drain regions is oppositely formed in the substrate adjacent to the gate stack, wherein the oxidation-proof layer suppresses oxidation encroachment between the gate stack and the substrate.

    摘要: Within a method for forming a silicon layer, there is employed at least one sub-layer formed of a higher crystalline silicon material and at least one sub-layer formed of a lower crystalline silicon material. The lower crystalline silicon material is formed employing a hydrogen treatment of the higher crystalline silicon material. The method is particularly useful for forming polysilicon based gate electrodes with enhanced dimensional control and enhanced performance.

    摘要: Generally disclosed is a method of a device comprising forming a polysilicon stack including a first and a second polysilicon layer with an intervening etch stop layer, wherein the first polysilicon layer height is at least one third a height of the polysilicon stack height, removing the second polysilicon layer and the etch stop layer, and reacting the first polysilicon layer with a metal to fully silicide the first polysilicon layer. Fully silicided (FUSI) gates can hence be formed with uniform gate height. The thin first polysilicon layer allows for siliciding with a lower thermal budge and with better uniformity of the silicide concentration throughout the layer.
