Abstract:
The channel of a MOSFET is selectively stressed by selectively stressing the silicide layers on the gate electrode and the source/drain. Stress in the silicide layer is selectively produced by orienting the larger dimensions of the silicide grains in a first direction and the smaller dimensions in a second, perpendicular direction, with one of the directions being parallel to the direction of carrier movement in the channel and the other direction being perpendicular thereto.
Abstract:
Disclosed is a method of manufacturing microelectronic devices including forming a silicon substrate with first and second wells of different dopant characteristics, forming a first strained silicon-germanium-carbon layer of a first formulation proximate to the first well, and forming a second strained silicon-germanium-carbon layer of a second formulation distinct from the first formulation proximate to the second well. Capping and insulating layers, gate structures, spacers, and sources and drains are then formed, thereby creating a CMOS device with independently strained channels.
