Title: Takuya Hamaguchi: Semiconductor Device and Testing Innovations.

Introduction

Takuya Hamaguchi is an inventor based in Tokyo, Japan, associated with Mitsubishi Electric Corporation. His patent work includes semiconductor device manufacturing and methods for testing semiconductor chips. His listed portfolio includes 4 patents.

Latest Patents

“Semiconductor Device and Manufacturing Method Therefor” describes a design that separates an organic protective film from a metallic film used for a solder joint. The spacing is at least half the protective film’s thickness. This arrangement is intended to reduce stress on the metallic film during sinter joining and help prevent cracking in the solder-connection film.

“Semiconductor Chip Testing Method and Semiconductor Chip Testing Device” presents a testing approach that evaluates chips on wafers or across a related group of wafers. It calculates the fraction of defective chips at corresponding wafer addresses and can change a chip’s result from non-defective to defective when that address’s fraction meets or exceeds a specified threshold.

Career Highlights

Hamaguchi’s listed inventions address two stages of semiconductor production: reliable solder connections in device manufacturing and data-informed screening during chip testing. Both focus on identifying or reducing potential sources of failure.

Collaborations

Hamaguchi is associated with Mitsubishi Electric Corporation. His listed coworkers include Tetsujiro Tsunoda and Hideki Haruguchi.

Conclusion

Takuya Hamaguchi’s patent work reflects a focus on semiconductor manufacturing reliability and chip-testing methods, with inventions aimed at preventing connection failures and improving defect identification.
