Latest Patents

One of Eguchi's latest patents is titled "Substrate bias through polysilicon line." This invention discloses a high-density integrated circuit that employs different first and second channel types of insulated gate field effect transistors. The design comprises at least three stacked wiring layers, with the lowest layer formed of polycrystalline silicon, which includes silicon gates of the transistors. One of the upper layers is also formed of polycrystalline silicon and is used for feeding a power supply to some of the transistors, connecting to at least one well region where the first channel type of transistors is formed. The other upper layer is made of high-conductivity metal.

Another notable patent is the "High speed-low power consuming IGFET integrated circuit." This improved semiconductor device operates at high speed while consuming low power. It includes a common impurity-doped region, a first insulated gate field effect transistor utilizing this region as a drain, and a second insulated gate field effect transistor also using the common impurity-doped region as a drain. The device features control means for simultaneous switching operations of both transistors and mechanisms for deriving an output signal from the common impurity-doped region.
