  • Patent number: 9449847
    Abstract: A semiconductor device is manufactured by forming semiconductor elements extending between a front surface and a rear side of a semiconductor layer. This includes forming a porous area at a surface of a semiconductor body that includes a porous structure in the porous area, forming the semiconductor layer on the porous area by epitaxial growth so as to have a thickness in a range of 5 ?m to 200 ?m, and forming semiconductor regions including source, drain, body, emitter, base and/or collector regions in a front surface of the semiconductor layer by ion implantation. After forming the semiconductor regions, hydrogen is introduced into the porous area by a thermal treatment, activating a reallocation of pores and causing cavities to be generated. The semiconductor layer is separated from the semiconductor body along the porous area. After the separation, rear side processing is applied to the semiconductor layer.
