An SOI wafer is constructed from a carrier wafer and a monocrystalline silicon layer having a thickness of less than 500 nm, an excess of interstitial silicon atoms prevailing in the entire volume of the silicon layer. The SOI wafers may be prepared by Czochralski silicon single crystal growth, the condition v/G

摘要:
Semiconductor wafers with a diameter of at least 200 mm comprise a silicon carrier wafer, an electrically insulating layer and a semiconductor layer located thereon, the semiconductor wafer having been produced by means of a layer transfer process comprising at least one RTA step, wherein the semiconductor wafer has a warp of less than 30 μm, a DeltaWarp of less than 30 μm, a bow of less than 10 μm and a DeltaBow of less than 10 μm. Processes for the production of a semiconductor wafer of this type require specific heat treatment regimens.
