Title: Takashi Tanakajima: Innovator in Semiconductor Wafer Processing

Introduction

Takashi Tanakajima is a prominent inventor based in Gunma, Japan. He has made significant contributions to the field of semiconductor wafer processing, holding a total of 2 patents. His innovative approaches have enhanced the efficiency and effectiveness of wafer handling and cleaning processes.

Latest Patents

Tanakajima's latest patents include a "Method for handling or processing semiconductor wafers" and an "Automatic cleaning apparatus for wafers." The first patent describes a method for handling wafers one at a time without the need for transporting them in a carrier. This method involves carrying the wafers to a loader assembly in a horizontal orientation, where they are then erected into a vertical orientation using stopper pins and a suction arm. This vertical positioning allows for efficient gripping by a transportation robot, which uses grooved gripping arms to minimize the force applied to the wafers. The cleaning process includes baths that support the wafers in a near-vertical orientation, ensuring effective cleaning without floating. A brush cleaning bath allows for simultaneous cleaning of both sides of the wafer, while a drying bath using infrared light completes the cleaning procedure.

The second patent, the "Automatic cleaning apparatus for wafers," follows a similar process, emphasizing the ability to clean wafers one at a time without the need for carriers. This apparatus also utilizes a loader assembly and a suction arm to achieve vertical orientation, ensuring that the wafers are cleaned efficiently and effectively.
