Abstract: A process for forming both tensile and compressive strained silicon layers to accommodate channel regions of MOSFET or CMOS devices has been developed. After formation of shallow trench isolation structures as well as application of high temperature oxidation and activation procedures, the fabrication sequences used to obtain the strained silicon layers is initiated. A semiconductor alloy layer is deposited followed by an oxidation procedure used to segregate a germanium component from the overlying semiconductor alloy layer into an underlying single crystalline silicon body. The level of germanium segregated into the underlying single crystalline silicon body determines the level of strain, which is in tensile state of a subsequently selectively grown silicon layer.

Abstract: A shallow trench isolation (STI) structure in a semiconductor substrate and a method for forming the same are provided. A trench is formed in a semiconductor substrate. A first dielectric layer is formed on sidewalls of the trench. The first dielectric layer is formed thicker at a top portion of the sidewalls than a bottom portion of the sidewalls and leaving an entrance of the trench open to expose the trench. A second dielectric layer is conformally formed on the first dielectric layer to close the entrance, thus forming a void buried within the trench. Thus, the stress between the trench dielectric layer and the surrounding silicon substrate during thermal cycling can be substantially reduced.

The semiconductor substrate is placed into a sputtering chamber. A silicide-forming metal layer, formed of a metal such as Co, Ni, is sputter-deposited over the exposed silicon surface. A process temperature is controlled below room temperature during the sputter deposition and preferably between approximately 0° C. to 10° C. The silicide-forming metal layer formed on the exposed silicon surface is first annealed to convert the silicide-forming metal layer into a salicide layer. Also, the system of the present invention is comprised of a sputter chamber including a mount for mounting a semiconductor substrate and a cooling mechanism coupled with the mount for cooling the semiconductor substrate. The cooling mechanism includes a controller to maintain a process temperature below room temperature.

Abstract: A novel gate structure and a method of forming the same for a self-aligned contact on a semiconductor substrate. The method includes forming a gate oxide layer on the semiconductor substrate. Then a first conductive layer is formed on the gate oxide layer. Next, a second conductive layer, preferably a refractory metal silicide (e.g. WSix), is formed overlying the first conductive layer. A capping layer is formed overlying the second conductive layer. Then the capping layer is etched to form a patterned capping layer having a lower outside corner. An upper portion of the second conductive layer is selectively dry etched laterally to form a lateral recess under the capping layer to increase etch margin. A lower portion of the second conductive layer is then etched anisotropically down to the first conductive layer along a sidewall approximately vertically aligned with the lower outside corner of the patterned capping layer.

Next, the silicon surface is heated to a predefined process temperature, thereby oxidizing at least a portion of the silicon surface. Finally, the semiconductor substrate is cooled. An ultra-thin oxide layer with uniform oxide characteristics, such as more boron penetration resistance, good oxide composition and thickness uniformity, increased charge to breakdown voltage in the oxide layer, can be formed.

Abstract: The degradation of integrity of the gate oxide in a CMOS transistor due to the formation of a tungsten silicide strapping layer on the polycrystalline silicon gate as a result of the migration of fluorine atoms from the tungsten hexafluoride used to form the tungsten silicide is reduced by increasing the dopant concentration of the polycrystalline silicon layer thereby to form dopant atoms in the grain boundaries of the polycrystalline silicon to block the migration of fluorine through the polycrystalline silicon to the underlying gate oxide. By preventing fluorine from reaching the gate oxide in this manner, the degradation of the gate oxide due to the replacement of oxygen by fluorine is decreased.
