Title: Innovations of Hatsuo Nakamura
Introduction
Hatsuo Nakamura is a prominent inventor based in Yokohama, Japan. He has made significant contributions to the field of semiconductor technology, holding a total of four patents. His work has had a lasting impact on the industry, particularly in the areas of pattern formation and wafer dicing.
Latest Patents
One of Nakamura's latest patents is a pattern forming system. This innovative system includes a reticule on which a pattern is formed on one or more chips. It features an apparatus for preliminarily arranging a plurality of shot regions of a main surface of a wafer in a matrix manner. This is particularly useful when regions where the pattern is formed by one shot are used as shot regions. Additionally, the system calculates the number of shot regions that constitute the matrix after sequentially moving the position of the shot regions. It also selects the optimal case in which the number of shot regions is minimized while maximizing the number of chips with a completely formed pattern. Another notable patent is a method of dicing a semiconductor wafer. This method involves creating a physical discontinuity on the surface of the wafer on both sides of a dicing line to limit the spreading of cracks and chips during the dicing process.
Career Highlights
Throughout his career, Nakamura has worked with several notable companies, including Tokyo Shibaura Denki and Toshiba Corporation. His experience in these organizations has allowed him to refine his skills and contribute to groundbreaking advancements in semiconductor technology.
