    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 bipolar transistor includes a first layer with a collector. A second layer has a base cutout for a base. A third layer includes a lead for the base. The third layer is formed with an emitter cutout for an emitter. An undercut is formed in the second layer adjoining the base cutout. The base is at least partially located in the undercut. In order to obtain a low transition resistance between the lead and the base, an intermediate layer is provided between the first and the second layer. The intermediate layer is selectively etchable with respect to the second layer. At least in the region of the undercut between the lead and the base, a base connection zone is provided that can be adjusted independent of other production conditions. The intermediate layer is removed in a contact region with the base.
