Title: Keizo Hasebe: Innovator in Semiconductor Technology
Introduction
Keizo Hasebe is a prominent inventor based in Kofu, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of 11 patents. His innovative work has advanced the methods used in film formation processes, which are crucial for semiconductor manufacturing.
Latest Patents
One of Hasebe's latest patents involves a film forming method and apparatus. In this invention, a solvent of a resist solution is dropped from a solvent supply nozzle onto the surface of a semiconductor wafer held by a spin chuck. The semiconductor wafer is then rotated by the spin chuck to spread the resist solution evenly across its surface. Simultaneously, the resist solution is dropped from a resist solution supply nozzle onto the wafer, following the solvent. During this process, the processing space is isolated from the outer atmosphere by closing a lid of a processing vessel, and a sprayed solvent is supplied into the processing space. This setup fills the processing space with a mist of solvent, which suppresses the evaporation of the solvent from the resist solution. As a result, a film of the resist solution is formed with a uniform thickness extending to the edge of the semiconductor wafer.
