    摘要: A method of ensuring against deterioration of an underlying silicide layer over which a refractory material layer is deposited by physical vapor deposition (PVD) or chemical vapor deposition (CVD) is realized by first providing a continuous polysilicon layer prior to the refractory material deposition. The continuous polysilicon layer, preferably no thicker than 50 Å, serves a sacrificial purpose and prevents interaction between any fluorine that is released during the refractory material deposition step from interacting with the underlying silicide.

    摘要: A structure which ensures against deterioration of an underlying silicide layer over which a refractory material layer is deposited by physical vapor deposition (PVD) or chemical vapor deposition (CVD) is realized by first providing a continuous polysilicon layer prior to the refractory material deposition. The continuous polysilicon layer, preferably no thicker than 50 Å, serves a sacrificial purpose and prevents damage to an underlying silicide layer by blocking interaction between any fluorine and the underlying silicide that is released when the refractory material is formed.

    摘要: The present invention provides a device design and method for forming Field Effect Transistors (FETs) that have improved performance without negative impacts to device density. The present invention forms high-gain p-channel transistors by forming them on silicon islands where hole mobility has been increased. The hole mobility is increased by applying physical straining to the silicon islands. By straining the silicon islands, the hole mobility is increased resulting in increased device gain. This is accomplished without requiring an increase in the size of the devices, or the size of the contacts to the devices.

    摘要: A mask (50′) with linewidth compensation and a method of making same. The mask provides for optimized imaging of isolated patterns (64) and nested patterns (70) present on the same mask. The compensated mask is formed from an uncompensated mask (50) and comprises an upper surface (56) upon which the isolated and nested patterns are formed. The isolated pattern comprises a first segment (76) having first sidewalls (76S). The nested pattern comprises second segments (72) proximate each other and having second sidewalls (72S). A partial conformal layer (86) covers the first segment and has feet (90) outwardly extending a distance d from the first sidewalls along the upper surface. The feet are preferably of a thickness that partially transmits exposure light.

    摘要: The present invention provides a method of forming nested and isolated images in a photosensitive resist. In the disclosed method, the entire surface of the photosensitive resist or selected regions thereof is exposed to a first mask having a set of nested, i.e. repeating pattern or grid images thereon, and then exposed to a second mask in order to remove unwanted portions of the nested image, so as to provide regions of nested and regions of isolated images in said photosensitive resist. The method may also be used to form regions having images in proximity to one another and regions having isolated images by exposing the entire surface of the photosensitive resist to a first mask having repeating patterns, and then removing entire or portions of the repeating patterns by exposure of the photosensitive resist with a second mask.
