Patent ID: 7323749

Claim:
A semiconductor device comprising an integrated circuit comprising a plurality of passive components selected from capacitors and resistors, the semiconductor device comprising a bottom substrate having a top surface portion and a bottom substrate polarity, a buried oxide layer deposited on at least a portion of the top surface of the bottom substrate, at least one dielectric intermediate insulating layer on at least a portion of the buried oxide layer, a dielectric top insulating layer, top metal connecting elements connected to said passive components by conductors extending through via holes, at least one of the passive components being formed of at least one silicon on insulator layer portion embedded within at least one of said insulating layers; wherein at least one further passive component is an implanted passive component of at least one implanted semiconductor material implanted under the buried oxide layer within the top surface portion of the bottom substrate, said implanted semiconductor material has a material polarity being opposite to the bottom substrate polarity.
