Title: Tetsuya Nakajima: Innovator in Semiconductor Technology
Introduction
Tetsuya Nakajima is a prominent inventor based in Kawasaki, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 4 patents. His work focuses on enhancing the efficiency and reliability of integrated circuits.
Latest Patents
One of Nakajima's latest patents involves a semiconductor integrated circuit with a protection circuit against electrostatic breakdown. In this innovation, diode rows are arranged at intervals in the same direction as the arrangement of cell rows. Each diode row features a series of pn junctions formed on a substrate, arranged along a track that is vertical to interconnection tracks. This design allows for automatic connections between the gates of MOS transistors and 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.
