    摘要: One embodiment of the present invention relates to method for the concurrent deposition of multiple different crystalline structures on a semiconductor body utilizing in-situ differential epitaxy. In one embodiment of the present invention a preparation surface is formed, resulting in two distinct crystalline regions, a monocrystalline silicon substrate region and an isolating layer region. A monocrystalline silicon layer and an amorphous silicon layer are concurrently formed directly onto the preparation surface in the monocrystalline silicon substrate region and the isolating layer region, respectively. Deposition comprises the formation of two or more sub-layers. The process parameters can be varied for each individual sub-layer to optimize deposition characteristics.

    摘要: A contact spring configuration for contacting semiconductor wafers is provided. At least one strip-type contact spring is provided on a substrate. The contact spring is fixed to a surface of the substrate on one side and is composed of a semiconductor material having a stress gradient which causes a permanent bending of the contact spring. The stress gradient in the semiconductor material is brought about by two semiconductor layers which are connected to one another and are mechanically strained differently. The different strains can be set by different doping or by deposition temperatures of different magnitude during the deposition of the semiconductor layers. The contact springs provide a good ohmic contact in particular with contact regions of a semiconductor wafer that are composed of a semiconductor material.
