    Abstract: The present invention provides a strained-Si structure, in which the nFET regions of the structure are strained in tension and the pFET regions of the structure are strained in compression. Broadly the strained-Si structure comprises a substrate; a first layered stack atop the substrate, the first layered stack comprising a compressive dielectric layer atop the substrate and a first semiconducting layer atop the compressive dielectric layer, wherein the compressive dielectric layer transfers tensile stresses to the first semiconducting layer, and a second layered stack atop the substrate, the second layered stack comprising an tensile dielectric layer atop the substrate and a second semiconducting layer atop the tensile dielectric layer, wherein the tensile dielectric layer transfers compressive stresses to the second semiconducting layer. The tensile dielectric layer and the compressive dielectric layer preferably comprise nitride, such as Si3N4.

    Abstract: PROBLEM TO BE SOLVED: To provide an SRAM cell design capable of simultaneously attaining high performance, low power, and small chip size by using only vertical MOSFET device including a peripheral (transmission) gate. SOLUTION: A method for forming a SRAM cell device comprises the steps of forming a pass gate FET transistor in a silicon layer formed on a flat insulating material and a parallel island, and further forming a pair of vertical pulldown FET transistors having a first common body and a first common source region. The method further forms a pulldown separation space for dividing an upper layer of a pullup and pulldown drain region of a pair of vertical pulldown FET transistor in two by etching through the upper diffusion between cross-linked inverter FET transistors, and the separation space reaches the common boby layer. The method further comprises the steps of forming a pair of vertical pullup FET transistor having a second common body and a second common drain, and connecting the FET transistor so as to form a SRAM cell.

    Abstract: Disclosed is a method to convert a stable silicon nitride film (101)covering a silicon substrate (100) into a stable silicon oxide film (102) with a low content of residual nitrogen in the resulting silicon oxide film. This is achieved by performing the steps of (i)providing a low pressure environment for the silicon nitride fim of between about l.33 X10 Pa(100 Torr) to about 13.3 Pa (0.1 Torr);(ii)introducing hydrogen and oxygen into said low pressure environment; and iii maintaining said low pressure environment at a temperature of about 600°C to about 1200 C° for a predetermined amount of time. This is an unexpectedand unique property of the in situ steam generation process since both silicon nitride and silicon oxide materials are chemically very stable compounds. Application of the claimed method to the art of microelectronic device fabrication, such as fabrication of on-chip dielectric capacitors and metal insulator semiconductor field effect transistors, is also disclosed.

    Abstract: A method for increasing the level of stress for amorphous thin film stressors by means of modifying the internal structure of such stressors is provided. The method includes first forming a first portion of an amorphous film stressor material (14) on at least a surface of a substrate (12), said first portion (18) having a first state of mechanical strain defining a first stress value. After the forming step, the first portion of the amorphous film stressor material is densified (20) such that the first state of mechanical strain is not substantiaUydtered,\vhile increasing the first stress value. In some embodiments, the steps of forming and densifying are repeated any number of times (20, 2OA, 20B) to obtain a preselected and desired thickness for the stressor.
