Abstract:
1. A method of producing a semiconductor body having a strained region, comprising: providing a first monocrystalline semiconductor region composed of a semiconductor material having a first lattice constant along a reference direction; and producing a second monocrystalline semiconductor region composed of the same semiconductor material as the first monocrystalline semiconductor region and a third, strained semiconductor region between the first and second monocrystalline semiconductor regions, by providing a semiconductor layer at a surface of the first monocrystalline semiconductor region and recrystallizing the semiconductor layer to form the second and third monocrystalline semiconductor regions such that the second monocrystalline semiconductor region has a second lattice constant, which is different from the first lattice constant along the reference direction, that induces a strain in the third monocrystalline semiconductor region.
