Title: Innovations of Tadashi Komiyama in Semiconductor Technology.
Introduction
Tadashi Komiyama is a notable inventor based in Kofu, Japan. He has made significant contributions to the field of semiconductor technology, holding three patents that showcase his innovative approaches to manufacturing semiconductor devices.
Latest Patents
His latest patents include methods for manufacturing semiconductor chips and devices, as well as connection substrates and electronic devices. One of the key embodiments of his inventions relates to a method for manufacturing a semiconductor chip, where semiconductor chips stacked in layers are electrically connected without using wires. This method involves forming an electrode on the surface of a first semiconductor chip and creating a hole from the opposite surface until a tungsten layer of the electrode is exposed. A protrusion is then formed on a second semiconductor chip, and an abutting electrode is created on the apex section of this protrusion. The two semiconductor chips are stacked such that the abutting electrode contacts the electrode, resulting in shorter paths between the electrodes, which inhibits signal delays. This innovative approach allows for the stacking of semiconductor chips of the same area, thereby reducing the size of the semiconductor device.
