    摘要

    With a complete performance investigation of the on-chip micromachined inductor with mechanical disturbances using ANSYS and HFSS simulators, an optimum structural design of the micromachined spiral inductors with fully CMOS compatible post-processes for RFIC applications is proposed in this paper. Via the incorporation of a sandwich dielectric membrane (0.7μm SiO 2 / 0.7μm Si 3 N 4 / 0.7μm TEOS) to enhance the structure rigidity, the inductor can have better signal stability. As compared, the new design of a 5nH micromachined inductor can have less 45% inductance variation than the conventional one while both devices operate at SGHz but with 10 m/sec 2 acceleration. Meanwhile, using a cross shape instead of blanket membrane can also effectively eliminate the inductance variation induced by the working temperature change (20°C to 75°C). It's our belief that the new micromachined inductors can have not only high Q performance but also better signal stability suitable for wide range RFIC applications.
