Title: Ikuo Suemune: Innovator in Semiconductor Technology
Introduction
Ikuo Suemune is a notable inventor based in Hiroshima, Japan. He has made significant contributions to the field of semiconductor technology, holding 2 patents that showcase his innovative approach to light-emitting devices and integrated circuits.
Latest Patents
One of his latest patents is a light-emitting semiconductor device. This device features an n-type (or p-type) base region sandwiched between a p-type (or n-type) emitter region and a p-type (or n-type) collector region. An injecting voltage source is connected across the emitter region and base region to apply a constant voltage. Additionally, a control voltage source is connected across the emitter region and collector region to selectively apply a reverse bias to the base-collector junction. This setup controls the recombination of carriers injected into the base region. The control voltage source produces non-emitting and emitting period voltages, allowing carriers injected during the non-emitting period to be captured in the base region, while those captured are allowed to recombine during the emitting period.
Another significant patent is for a three-dimensional integrated circuit with optically coupled shared memory layers. In this multi-layered integrated device, adjacent memory layers are optically coupled, enabling data written on one layer to be copied onto its adjacent layers through optical coupling.
