    摘要: The present application discloses a method of forming a semiconductor structure. In at least one embodiment, the method includes forming a polysilicon layer over a substrate. A mask layer is formed over the polysilicon layer. The mask layer is patterned to form a patterned mask layer. A polysilicon structure is formed by etching the polysilicon layer using the patterned mask layer as a mask. The polysilicon structure has an upper surface and a lower surface, and the etching of the polysilicon layer is arranged to cause a width of the upper surface of the polysilicon structure greater than that of the lower surface of the polysilicon structure.

    摘要: A metal-oxide-semiconductor (MOS) device having a selectable threshold voltage determined by the composition of an etching solution contacting a metal layer. The MOS device can be either a p-type or n-type MOS and the threshold voltage is selectable for both types of MOS devices. The etching solution is either an oxygen-containing solution or a fluoride-containing solution. The threshold voltage is selected by adjusting the flow rate of inert gases into an etching chamber to control the concentration of oxygen gas or nitrogen trifluoride.
