Latest Patents
Satoru Sumi's latest patents include a semiconductor integrated circuit with a protection circuit against electrostatic breakdown. This innovative design features diode rows arranged at intervals in the same direction as the arrangement of cell rows. Each diode row contains a series of pn junctions formed on a substrate, arranged along a track that is vertical to interconnection tracks. The interconnections between cells automatically connect the gates of MOS transistors to the diodes, eliminating the need to determine which gate should connect to which diode. The wiring length between the gate of the MOS transistor and a diode is kept below a specified upper limit to prevent electrostatic breakdown at the gate oxide during the fabrication process. Additionally, each pn junction can be strategically placed under necessary input signal lines, ground lines, the bottom of the drain of the MOS transistor, or under the power supply line outside of the macrocell.
