Abstract:
Etching trench isolation structures into a semiconductor structure that includes an upper thin semiconductor layer disposed over a buried insulator layer and a buried compressively strained stressor layer under the buried insulator layer, the compressively strained stressor layer being disposed on an underlying semiconductor substrate, causes edge relaxation of the compressively strained stressor layer. The edge relaxation results in the buried insulation layer being deformed, thus inducing tensile strain in an upper surface of the thin semiconductor layer across at least a first portion of a lateral extent of the thin semiconductor layer between walls of one or more trenches formed by the etching.

Claim (Index 1):
A device structure comprising:\n a semiconductor substrate having first and second walls of one or more trench isolation structures extending partially into the substrate, a substrate interface region extending between the first and second walls; a buried stressor structure on the substrate interface region and extending over a lateral extent between the first and second walls, the buried stressor structure having in-plane compressive stress; a buried insulation layer comprising silicon dioxide over the buried stressor structure; a thin upper semiconductor layer over the buried insulation layer, the thin upper semiconductor layer extending between the first and second walls and having in-plane tensile strain induced within a first portion of the thin upper semiconductor layer extending between the first and second walls, the strain induced by deformation of the buried insulation layer; and an integrated circuit device having an active region at least partially in the first portion of the thin upper semiconductor layer, wherein the deformation of the buried insulation layer is caused by edge relaxation of the buried stressor structure.
