摘要： An improved SRAM and fabrication method are disclosed. The method comprises use of a nitride layer to encapsulate PFETs and logic NFETs, protecting the gates of those devices from oxygen exposure. NFETs that are used in the SRAM cells are exposed to oxygen during the anneal process, which alters the effective work function of the gate metal, such that the threshold voltage is increased, without the need for increasing the dopant concentration, which can adversely affect issues such as mismatch due to random dopant fluctuation, GIDL and junction leakage.

摘要： A method is provided of fabricating complementary stressed semiconductor devices, e.g., an NFET having a tensile stressed channel and a PFET having a compressive stressed channel. In such method, a first semiconductor region having a lattice constant larger than silicon can be epitaxially grown on an underlying semiconductor region of a substrate. The first semiconductor region can be grown laterally adjacent to a second semiconductor region which has a lattice constant smaller than that of silicon. Layers consisting essentially of silicon can be grown epitaxially onto exposed major surfaces of the first and second semiconductor regions after which gates can be formed which overlie the epitaxially grown silicon layers. Portions of the first and second semiconductor regions adjacent to the gates can be removed to form recesses. Regions consisting essentially of silicon can be grown within the recesses to form embedded silicon regions. Source and drain regions then can be formed in the embedded silicon regions. The difference between the lattice constant of silicon and that of the underlying first and second regions results in tensile stressed silicon over the first semiconductor region and compressive stressed silicon over the second semiconductor region.

摘要： A semiconductor device structure is provided which includes a first field effect transistor (“FET”) having a first channel region, a first source region, a first drain region and a first gate conductor overlying the first channel region. A second FET is included which has a second channel region, a second source region, a second drain region and a second gate conductor overlying the second channel region. The first and second gate conductors are portions of a single elongated conductive member extending over both the first and second channel regions. A first stressed film overlies the first FET, the first stressed film applying a stress having a first value to the first channel region. A second stressed film overlies the second FET, the second stressed film applying a stress having a second value to the second channel region. The second value is substantially different from the first value. In addition, the first and second stressed films abut each other at a common boundary and present a substantially co-planar major surface at the common boundary.

摘要： The present invention relates to improved complementary metal-oxide-semiconductor (CMOS) devices with stressed channel regions. Specifically, each improved CMOS device comprises an field effect transistor (FET) having a channel region located in a semiconductor device structure, which has a top surface oriented along one of a first set of equivalent crystal planes and one or more additional surfaces oriented along a second, different set of equivalent crystal planes. Such additional surfaces can be readily formed by crystallographic etching. Further, one or more stressor layers with intrinsic compressive or tensile stress are located over the additional surfaces of the semiconductor device structure and are arranged and constructed to apply tensile or compressive stress to the channel region of the FET. Such stressor layers can be formed by pseudomorphic growth of a semiconductor material having a lattice constant different from the semiconductor device structure.

摘要： A CMOS diode and method of making it are disclosed. In one embodiment, the diode comprises a silicon substrate having an N doped region and a P doped region. A first silicide region is formed on the N doped region of the silicon substrate, and a second silicide region formed on the P doped region of the silicon substrate. The first silicide region is comprised of a material having a bandgap value lower than the bandgap value of the material comprising the second silicide region. The result is a diode where the workfunction of each region of silicide more closely matches the workfunction of the doped silicon it contacts, resulting in reduced contact resistance. This provides for a diode with improved performance characteristics.
