摘要： A field effect transistor gate structure and a method of fabricating the gate structure with a high-k gate dielectric material and high-k spacer are described. A gate pattern or trench is first etched in a dummy organic or inorganic film deposited over a silicon substrate with source/drain regions. A high-k dielectric material liner is then deposited on all exposed surfaces. Excess poly-silicon gate conductor film is then deposited within and over the trench to provide adequate overburden. Poly-silicon is then planarized with chemical mechanical polishing or etch-back methods such that the high-k material film on top of the dummy film surface is removed during this step. In the final step, the dummy film is disposed off, leaving the final transistor gate structure with high-k gate dielectric and high-k spacer surrounding the gate conductor poly-silicon, with the entire gate structure fabricated to form an FET device on a silicon substrate.

摘要： A method is provided for improving the tungsten, W-filling of hole openings in semiconductor substrates. This is accomplished by forming an opening—which can be used either as a contact or via hole—with a faceted entrance along with tapered side-walls. This combination of faceted entrance and tapered side-walls improves substantially the tungsten W-filling of contact/via holes in substrates without the formation of key-holes, thereby resulting in metal plugs of high electrical integrity and high reliability.

摘要： A plasma etch method for etching a dielectric layer and an etch stop layer to reach a metal silicide layer formed thereunder employs for etching the etch stop layer an etchant gas composition comprising a fluorine containing gas and a nitrogen containing gas, preferably with a carrier gas such as argon or helium, but without an oxygen containing gas or a carbon and oxygen containing gas. The plasma etch method is selective for the etch stop layer with respect to the metal silicide layer, thus maintaining the physical and electrical integrity of the metal silicide layer.

摘要： An improved method of etching very small contact holes through dielectric layers used to separate conducting layers in multilevel integrated circuits formed on semiconductor substrates has been developed. The method uses bi-level ARC coatings in the resist structure and a unique combination of gaseous components in a plasma etching process which is used to dry develop the bi-level resist mask as well as etch through a silicon oxide dielectric layer. The gaseous components comprise a mixture of a fluorine containing gas, such as C4F8, C5F8, C4F6, CHF3 or similar species, an inert gas, such as helium or argon, an optional weak oxidant, such as CO or O2 or similar species, and a nitrogen source, such as N2, N2O, or NH3 or similar species. The patterned masking layer can be used to reliably etch contact holes in silicon oxide layers on semiconductor substrates, where the holes have diameters of about 0.1 micron or less.

摘要： A new method for fabricating a borderless interconnection in a semiconductor device is provided. During fabrication, the device includes an interlevel dielectric (ILD) layer, a metal silicide layer, and a stop layer disposed between the ILD and metal silicide layers. The stop layer may be formed of silicon nitride or silicon oxynitride, and the metal silicide layer may be a nickel silicide. The method includes etching the ILD layer to expose at least a portion of the stop layer and then performing a nitrogen plasma treatment on the exposed portion of the stop layer. After the treatment, the exposed portion of the stop layer is removed to provide the interconnection hole. Because of the plasma treatment, damage to the metal silicide underlying the stop layer will be minimized when the stop layer is removed.
