Latest Patents

Uemori is associated with 1 patent, titled “Advanced Lift Method and Apparatus for Transferring Optical Devices Using Laser Emission and Photomask Techniques.” The invention describes using laser-induced forward transfer, or LIFT, to relocate optical devices from a sapphire donor substrate to a carrier substrate. By synchronizing the donor and receptor substrates’ movement and setting their speed ratio according to the devices’ array pitch and the display’s pixel pitch, the method can place devices at the required display pitch, including when the pitches are not integer multiples.

Career Highlights

The patent highlights Uemori’s work on adapting optical-device transfer processes to the precise spacing requirements of display manufacturing. It combines substrate movement control with laser transfer techniques.

Collaborations

The patent lists Masahiko Sato and Hiroshi Yamaoka as coworkers associated with the invention. Their collaboration reflects a shared effort to develop a method for accurately positioning optical devices on carrier substrates.

Conclusion

Nobutaka Uemori’s patent focuses on synchronizing substrate motion and laser transfer to place optical devices at display-ready pitches.
