Title: Innovations of Yoshimitsu Tamura
Introduction
Yoshimitsu Tamura is a prominent inventor based in Chiba, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 5 patents. His work focuses on improving semiconductor memory devices and contact barrier applications.
Latest Patents
One of his latest patents is a semiconductor memory device with antifuse. The objective of this invention is to provide a type of semiconductor memory device whose antifuse can be formed without any additional film manufacturing process. A first electrode is formed by a first polysilicon film on a semiconductor substrate, and a second polysilicon film is deposited on the surface of the first polysilicon film. The first electrode, a dielectric film formed on the surface of the first electrode, and a second electrode form a capacitor in the memory cell. An antifuse, with the same configuration as the capacitor, is formed in the semiconductor memory device. Because there is no need to use an additional film, the manufacturing cost is low, and the antifuse can be easily arranged. It is also possible to form the antifuse by using Tungsten-nitride for contact barrier application instead of depositing the second polysilicon film on the surface of the first polysilicon film.
