Latest Patents

Ikumi Kashiwagi holds a patent for a "Semiconductor thin film crystallization device and semiconductor thin film crystallization method." This invention involves a sophisticated process where a first laser beam is emitted in a pulsed manner at a high repetition frequency. The beam is converged onto a substrate to form a slit-like first beam spot. A second laser beam is then emitted to rise before and fall after the first beam, also converging onto the substrate. 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. The process significantly improves throughput in semiconductor production.
