  • Patent number: 7189625
    Abstract: In a micromachine according to this invention, a polyimide film is formed on the surface of each electrode. The polyimide film is formed as follows. A substrate having each electrode and a counterelectrode are dipped in an electrodeposition polyimide solution, and a positive voltage is applied to the electrode. A material dissolved in the electrodeposition polyimide solution is deposited on a surface of the positive-voltage-applied electrode that is exposed in the solution, thus forming a polyimide film on the surface.

  • Patent number: 7176530
    Abstract: A semiconductor technology combines a normally off n-channel channel-junction insulated-gate field-effect transistor (“IGFET”) (104) and an n-channel surface-channel IGFET (100 or 160) to reduce low-frequency 1/f noise. The channel-junction IGFET is normally of materially greater gate dielectric thickness than the surface-channel IGFET so as to operate across a greater voltage range than the surface-channel IGFET. Alternatively or additionally, the channel-junction IGFET may conduct current through a field-induced surface channel. A p-channel surface-channel IGFET (102 or 162), which is typically of approximately the same gate-dielectric thickness as the n-channel surface-channel IGFET, is preferably combined with the two n-channel IGFETs to produce a complementary-IGFET structure. A further p-channel IGFET (106, 180, 184, or 192), which is typically of approximately the same gate dielectric thickness as the n-channel channel-junction IGFET, is also preferably included.
