    摘要: By forming a substantially continuous and uniform semiconductor alloy in one active region while patterning the semiconductor alloy in a second active region so as to provide a base semiconductor material in a central portion thereof, different types of strain may be induced, while, after providing a corresponding cover layer of the base semiconductor material, well-established process techniques for forming the gate dielectric may be used. In some illustrative embodiments, a substantially self-aligned process is provided in which the gate electrode may be formed on the basis of layer, which has also been used for defining the central portion of the base semiconductor material of one of the active regions. Hence, by using a single semiconductor alloy, the performance of transistors of different conductivity types may be individually enhanced.

    摘要: Methods for fabricating low contact resistance CMOS integrated circuits are provided. In accordance with an embodiment, a method for fabricating a CMOS integrated circuit including an NMOS transistor and a PMOS transistor disposed in and on a silicon-comprising substrate includes depositing a first silicide-forming metal on the NMOS and PMOS transistors. The first silicide-forming metal forms a silicide at a first temperature. At least a portion of the first silicide-forming metal is removed from the NMOS or PMOS transistor and a second silicide-forming metal is deposited. The second silicide-forming metal forms a silicide at a second temperature that is different from the first temperature. The first silicide-forming metal and the second silicide-forming metal are heated at a temperature that is no less than the higher of the first temperature and the second temperature.

    摘要: In a memory cell, the drive current capabilities of the transistors may be adjusted by locally providing an increased gate dielectric thickness and/or gate length of one or more of the transistors of the memory cell. That is, the gate length and/or the gate dielectric thickness may vary along the transistor width direction, thereby providing an efficient mechanism for adjusting the effective drive current capability while at the same time allowing the usage of a simplified geometry of the active region, which may result in enhanced production yield due to enhanced process uniformity. In particular, the probability of creating short circuits caused by nickel silicide portions may be reduced.
