    摘要: In a method of making a semiconductor device, a first gate stack is formed on a substrate at a pFET region, which includes a first gate electrode material. The source/drain regions of the substrate are etched at the pFET region and the first gate electrode material of the first gate stack is etched at the pFET region. The etching is at least partially selective against etching oxide and/or nitride materials so that the nFET region is shielded by a nitride layer (and/or a first oxide layer) and so that the spacer structure of the pFET region at least partially remains. Source/drain recesses are formed and at least part of the first gate electrode material is removed by the etching to form a gate electrode recess at the pFET region. A SiGe material is epitaxially grown in the source/drain recesses and in the gate electrode recess at the pFET region. The SMT effect is achieved from the same nitride nFETs mask.

    摘要: A process for forming a strained channel region for a MOSFET device via formation of adjacent silicon-germanium source/drain regions, has been developed. The process features either blanket deposition of a silicon-germanium layer, or selective growth of a silicon-germanium layer on exposed portions of a source/drain extension region. A laser anneal procedure results in formation of a silicon-germanium source/drain region via consumption of a bottom portion of the silicon-germanium layer and a top portion of the underlying source/drain region. Optimization of the formation of the silicon-germanium source/drain region via laser annealing can be achieved via a pre-amorphization implantation (PAI) procedure applied to exposed portions of the source/drain region prior to deposition of the silicon-germanium layer. Un-reacted top portions of the silicon-germanium layer are selectively removed after the laser anneal procedure.

    摘要: A structure, semiconductor device and method having a substantially L-shaped silicide element for a contact are disclosed. The substantially L-shaped silicide element, inter alia, reduces contact resistance and may allow increased density of CMOS circuits. In one embodiment, the structure includes a substantially L-shaped silicide element including a base member and an extended member, wherein the base member extends at least partially into a shallow trench isolation (STI) region such that a substantially horizontal surface of the base member directly contacts a substantially horizontal surface of the STI region; and a contact contacting the substantially L-shaped silicide element. The contact may include a notch region for mating with the base member and a portion of the extended member, which increases the silicide-to-contact area and reduces contact resistance. Substantially L-shaped silicide element may be formed about a source/drain region, which increases the silicon-to-silicide area, and reduces crowding and contact resistance.

    摘要: One of the limitations to current usage of scanning thermal microscopes arises when one needs to obtain a thermal map of an electrically biased specimen. Current practice is for the conductive parts of the specimen to be passivated to prevent excessive current leakage between the tip and the conductive sample. The present invention eliminates the need for this by coating the probe's microtip with a layer of insulation that is also a good thermal conductor. Examples of both thermocouple and thermistor based probes are given along with processes for their manufacture.
