    Abstract: 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.

    Abstract: 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.

    Abstract: In a method for generating a protective cover for a device, where a substrate is provided, which comprises the device, first, a sacrificial pattern is generated on the substrate. The sacrificial pattern covers at least an area of the substrate, which comprises the device. Then, a polymer layer is deposited, which comprises at least on sacrificial pattern. Then, an opening will be formed in the polymer layer to expose a portion of the sacrificial pattern. Then, the sacrificial pattern will be removed and the formed opening in the polymer layer is closed.
