Patent ID: 6909163

Claim:
A high frequency oscillator for an integrated semiconductor circuit, characterized in that the high frequency oscillator ( 30 ) is a component of the semiconductor circuit ( 10 ), which is comprised of a first silicon layer ( 12 ), an adjoining silicon dioxide layer (insulation layer ( 14 )), and an additional subsequent silicon layer (structured layer ( 16 )), (SOI wafer), wherein the high frequency oscillator ( 30 ) is comprised of (a) a resonator ( 24 ) with a metallized cylinder ( 18 ) made of silicon disposed in the structured layer ( 16 ) and a coupling disk ( 28 ) that overlaps the metallized cylinder ( 18 ) in the vicinity of the first silicon layer ( 12 ), and (b) an IMPATT diode ( 32 ) that is connected to the metallized cylinder ( 18 ) of the resonator ( 24 ) via a recess ( 38 ) in the coupling disk ( 28 ).
