| 摘要 |
Semiconductor film or layer is made by: producing structures of repeating recesses (2) of prescribed geometry on a semiconductor material surface; thermally treating until a layer with periodically repeating hollow chambers (3) forms below a closed layer (4) on the material surface; and separating the closed layer on the surface along the layer of hollow chambers from the rest of the material. Preferred Features: The semiconductor material is made from silicon, silicon-germanium, gallium arsenide, silicon carbide or indium phosphide, preferably doped with foreign materials. The semiconductor material is monocrystalline. |
