Latest Patents

Hirata's latest patents showcase his inventive prowess and focus on enhancing manufacturing processes. One of his notable inventions is a method of making a layer containing magnetic material. This involves forming a magnetic material layer on a substrate and utilizing a magnetic head to scan an etching region, thereby arranging magnetic polarization uniformly. Furthermore, he developed a technique that allows for the separation of the layer into a ferromagnetic region, where polarization aligns in one direction, and a feeble magnetic region, where it's not. The ferromagnetic region is subsequently removed by exploiting differences in etching rates tied to the magnetic field densities of the two regions.

Another significant patent addresses methods for determining the end of cleaning in semiconductor manufacturing. This innovative process involves monitoring impedance or temperature changes in a semiconductor substrate's process chamber during plasma discharge cleaning. By detecting an abrupt shift in either parameter, the precise end of the cleaning process can be determined, enhancing efficiency and reliability in semiconductor manufacturing.
