摘要:
The present invention provides a method for manufacturing a semiconductor device as well as a semiconductor device. The method, among other steps, may include forming a gate structure over a substrate, and forming a strain inducing sidewall spacer proximate a sidewall of the gate structure, the strain inducing sidewall configured to introduce strain in a channel region below the gate structure.

A method of forming a semiconductor device includes forming one or more sidewall spacer layers on the outer surface of a gate stack. At least one region of an at least partially formed semiconductor device is doped. First and second sidewall bodies are formed on opposing sides of the gate stack. The formation of the first and second sidewall bodies includes forming a first sidewall-forming layer on the outward surface of the gate stack and the sidewall spacer layers, exposing the semiconductor device to a heating cycle in a single wafer reactor, and forming a second sidewall-forming layer on the outward surface of the first sidewall-forming layer. The formation of the second sidewall-forming layer occurs in an environment that substantially minimizes dopant loss and deactivation in the at least one region of the partially formed semiconductor device.
摘要:
A method for forming planar isolation structures for integrated circuits. A etch barrier is formed over the isolation fill material and an etch back is performed to remove material above unetched portions of the substrate. The exposed fill material is etched and planarized to form a planar isolation structure.
