摘要: A polycide gate structure and a method of forming the polycide gate. A substrate having a gate dielectric layer, a polysilicon layer, a silicide layer and an insulation layer thereon is provided. The polysilicon layer is above the gate dielectric layer, the silicide layer is above the polysilicon layer, and the insulation layer is above the silicide layer. A patterned photoresist layer is formed over the insulation layer. Using the photoresist layer as a mask, an anisotropic etching operation is carried out to remove the exposed insulation layer. Again using the photoresist layer as a mask, a first type of plasma is used to carry out a first anisotropic etching operation to remove the exposed silicide layer. A metallic oxide layer is formed on the sidewalls of the silicide layer by the oxidation of a portion of the retained silicide layer. Using the photoresist layer as a mask, a second type of plasma is used to carry out a second anisotropic etching operation to remove the exposed polysilicon layer. The metallic oxide layer is resistant to attack by the second type of plasma.

摘要: The method of forming a polysilicon layer is provided. A first polysilicon layer with a first grain size is formed on a substrate. A second polysilicon layer with a second grain size is formed on the first polysilicon layer. The first grain size is smaller than the second grain size. The first polysilicon layer with a smaller grain size can serve as a base for the following deposition, so that the second polysilicon layer formed thereon has a flatter topography, and thus, the surface roughness is reduced and the Rs uniformity within a wafer is improved.

摘要: A domed plasma reactor chamber uses an antenna driven by RF energy (LF, MF, or VHF) which is inductively coupled inside the reactor dome. The antenna generates a high density, low energy plasma inside the chamber for etching metals, dielectrics and semiconductor materials. Auxiliary RF bias energy applied to the 10 wafer support cathode controls the cathode sheath voltage and controls the ion energy independent of density. Various magnetic and voltage processing enhancement techniques are disclosed, along with etch processes deposition processes and combined etch/deposition processed. The disclosed invention provides processing of sensitive devices without damage and without microloading, thus providing increased yields.
