Title: Kazuhide Hasebe: Innovator in Semiconductor Technology
Introduction
Kazuhide Hasebe is a notable inventor based in Yamanashi-ken, Japan. He has made significant contributions to the field of semiconductor technology, particularly in the formation of silicon films and doped polysilicon films. With a total of two patents to his name, Hasebe's work has implications for the manufacturing of micronized devices.
Latest Patents
Hasebe's latest patents include a method for forming doped polysilicon films and a method for forming silicon films. The method for forming doped polysilicon films involves loading a number of wafers into a reaction vessel on a wafer boat. Monosilane gas, phosphine gas, and N.sub.2 O gas are supplied to create an amorphous silicon film doped with phosphorus. The wafers are then annealed in a different reaction tube to polycrystallize the amorphous silicon film. Oxygen generated by the decomposition of N.sub.2 O is incorporated into the film, serving as nuclei for silicon crystals, which enhances the uniformity of resistance values in micronized devices. The second patent, a method for forming silicon films, retains semiconductor wafers in a wafer boat, which is then loaded into a process tube of a vertical thermal processing apparatus. The process tube is heated to temperatures between 300°C and 530°C in a depressurized atmosphere, while a disilane gas flows at a rate of 300 SCCM or more to form silicon films.
