A planar waveguide structure for mm-wave transmitters and receivers. The active semiconductor component elements and the planar waveguide with which they are connected of the transmitters and/or receivers are arranged on the front side of a semiconductor substrate. The rear side or surface of the semiconductor substrate is at least partially formed as an inwardly or outwardly radiating surface and is geometrically shaped such that an electromagnetic property incident or emanating radiation is altered in a predetermined manner.

A structured semiconductor body based on a Si substrate and having monocrystalline semiconductor regions and barrier regions which contain polycrystalline silicon which have preferably been produced in an Si-MBE process. The barrier regions are provided to delimit the monocrystalline Si semiconductor structures to prevent undesired current flow, for example between two monocrystalline devices of an integrated circuit. The polycrystalline silicon of the barrier regions has a substantially lower electrical conductivity than the monocrystalline regions, and consequently it is possible to spatially selectively dope portions the barrier region so as to provide regions which electrically contact a monocrystalline silicon region. In a preferred embodiment a polycrystalline silicon region within the barrier region is doped so that it forms a pn-junction with the adjacent monocrystalline semiconductor region and can be used, for example, as an emitter zone of a bipolar device.

The invention relates to a method for monitoring the breakdown of a pn junction in a semiconductor component and to a semiconductor component adapted to carrying out said method. According to the method, optical radiation which is emitted if a breakdown occurs on a pn junction is detected by a photosensitive electronic component (8) integrated into the semiconductor component. The supply of the pn junction is controlled according to the detected radiation to prevent a complete breakdown during operation of the semiconductor component. The method according to the invention and the semiconductor component adapted thereto permit the operating range of the semiconductor component to be extended and the power output to be increased without the risk of destruction.
