Abstract
It is provided that the semiconductor component is a component of a semiconductor circuit () comprising a first silicon layer (), an adjoining silicon dioxide layer (insulating layer ()) and a subsequent further silicon layer (structured layer ()) (SOI wafer), and the semiconductor component comprises an IMPATT oscillator (), having a resonator () which includes a metallized cylinder () of silicon, disposed in the structured layer (); a coupling disk () covering the cylinder () in the region of the first layer (); and an IMPATT diode (), communicating with the cylinder () of the resonator () via a recess () in the coupling disk (); and a reference oscillator () of lower frequency, having a resonator () which includes a metal cylinder () of silicon, disposed in the structured layer (), and coupling disk () covering the cylinder in the region of the first layer (); and a microwave conductor, communicating with the cylinder () of the resonator () via a recess () in the coupling disk (), and the reference oscillator, via an active oscillator circuit (), serves the purpose of frequency stabilization of the IMPATT oscillator (); with integrated Schottky diodes; and a transmitting and receiving antenna ().
