Latest Patents

Taniguchi's latest patents include the "Laser Beam Projection Mask" and the "Laser Beam Machining Method and Laser Beam Machine Using Same." The laser beam projection mask features three rectangular-shaped slits as transmission areas. These slits are arranged sequentially in the X direction at specified intervals, with the width decreasing in the order of the slits. The transmission coefficients of these areas are designed to conform to a temperature distribution curve of a silicon film.

The second patent involves a semiconductor thin film crystallization device and method. In this innovation, a first laser beam is emitted in a pulsed manner at a high repetition frequency and is focused onto a substrate to create a slit-like beam spot. A second laser beam is also emitted in a pulsed manner, overlapping with the first beam spot. This method allows for the crystallization of a semiconductor thin film, resulting in a crystal surface that is exceptionally flat, has minimal defects, and features large crystal grains.
