Shusaku Ozawa

Title: Shusaku Ozawa and Optical Device Transfer Innovation.

Introduction

Shusaku Ozawa is an inventor associated with Funabashi, Japan, and Shin-Etsu Chemical Ltd. His work includes a patented method for transferring optical devices onto a carrier substrate at a pitch suited to a display’s pixel layout.

Latest Patents

The supplied information lists one patent for Ozawa: “Advanced Lift Method and Apparatus for Transferring Optical Devices Using Laser Emission and Photomask Techniques.” The invention addresses cases where a display’s pixel pitch is not an integer multiple of the spacing between optical devices arranged on a sapphire donor substrate. It determines a movement-speed ratio between the donor and receptor substrates from their respective device pitches, then synchronizes laser-induced forward transfer (LIFT) with donor-substrate movement. This enables the devices to be placed on the carrier substrate at the display’s pixel pitch. Ozawa is credited with 1 patent in the information provided.

Career Highlights

Ozawa’s listed patent focuses on coordinating substrate movement and laser transfer to achieve precise optical-device placement. The supplied information identifies Shin-Etsu Chemical Ltd. as his company.

Collaborations

The supplied information names Masami Kurata and Masahiko Sato as Ozawa’s coworkers. It does not specify their roles in the patent or describe particular collaborative contributions.

Conclusion

Shusaku Ozawa’s listed invention addresses a key alignment challenge in transferring optical devices for display applications by synchronizing substrate movement with laser-based placement.
