Title: Norimasa Matsui: Innovations in Printing and Semiconductor Processing.

Introduction

Norimasa Matsui is an inventor associated with Kyoto, Japan, and Screen Holdings Co., Ltd. His work includes inventions in ink-jet printing and semiconductor wafer heat treatment. Matsui is credited with 2 patents.

Latest Patents

Matsui’s listed patents address equipment and methods for controlling airflow and temperature during manufacturing processes.

The patent “Ink-jet printer and ink-jet printing method” describes a printer that transports a base material along a path beneath an ink-ejection head. A base plate holds the head and contains an air-flow passage that directs air toward the transport path downstream of the ink-ejection port.

The patent “Heat treatment apparatus of light irradiation type” concerns heating a semiconductor wafer with continuous lighting followed by a flash of light. A light-absorption ring near the wafer’s edge absorbs infrared light during preliminary heating, helping compensate for heat loss and promote a uniform temperature across the wafer. The ring transmits visible light, reducing the risk of damage from the subsequent flash irradiation.

Career Highlights

Matsui’s listed inventions apply engineering solutions to two distinct manufacturing challenges: directing airflow in ink-jet printing and managing temperature distribution during semiconductor processing. Both patents describe apparatus features intended to support reliable operation.

Collaborations

Matsui’s listed coworkers include Takashi Kuroda and Tamio Fukui. His company affiliation is Screen Holdings Co., Ltd.

Conclusion

Norimasa Matsui’s patent work spans printing technology and semiconductor heat treatment, with a focus on practical equipment designs for controlling airflow and thermal conditions.
