Abstract:
A metal gate/high-k dielectric semiconductor device provides an NMOS gate structure and a PMOS gate structure formed on a semiconductor substrate. The NMOS gate structure includes a high-k gate dielectric treated with a dopant impurity such as La and the high-k gate dielectric material of the PMOS gate structure is deficient of this dopant impurity and further includes a work function tuning layer over the high-k gate dielectric. A process for simultaneously forming the NMOS and PMOS gate structures includes forming the high-k gate dielectric material, and the work function tuning layer thereover, then selectively removing the work function tuning layer from the NMOS region and carrying out a plasma treatment to selectively dope the high-k gate dielectric material in the NMOS region with a dopant impurity while the high-k gate dielectric in the PMOS region is substantially free of the dopant impurity.

Abstract:
The present invention discloses a method for forming metal silicide on an electronic structure by first depositing a metal layer on top of a silicon layer of polysilicon, single crystal silicon or amorphous silicon capable of forming a metal silicide, and then irradiating the metal layer with laser energy for a sufficient length of time such that a layer of metal silicide is formed at the metal interface with polysilicon, single crystal silicon and amorphous silicon. The unreacted metal layer on the metal silicide is then removed by a wet dipping method by selecting a suitable etchant for the metal. The present invention novel method can be applied to various metallic materials such as Ti, Co, W, Pt, Hf, Ta, Mo, Pd and Cr. The laser source utilized is a pulse Excimer laser of XeCl, ArF or XeF.
Abstract:
The present invention includes forming a conductive layer on a substrate. Portions of the conductive layer are removed using a first photoresist layer as a mask. A first oxide layer is formed over the conductive layer and the substrate, and an amorphous silicon layer is then formed on the first oxide layer. After annealing the amorphous silicon layer, thereby transforming amorphous silicon layer to a polysilicon layer, a second oxide layer is formed on the polysilicon layer. The second oxide layer is removed using a second photoresist layer as a mask. An amorphous silicon carbon layer is formed over the second oxide layer and the polysilicon layer, and a heavily-doped amorphous silicon carbon layer is formed on the amorphous silicon carbon layer. After annealing the heavily-doped amorphous silicon carbon layer and the amorphous silicon carbon layer, thereby transforming the heavily-doped amorphous silicon carbon layer to a heavily-doped polysilicon carbon layer, and transforming the amorphous silicon carbon layer to a polysilicon carbon layer, portions of the polysilicon carbon layer, the heavily-doped polysilicon carbon layer and the polysilicon layer are removed using a third photoresist layer as a mask.
