Complete crystallization of a thin film with a single laser scan
- 總結
- Crystallization of semiconductor thin films is used in the manufacture of many devices, including thin film transistors, image sensors, and liquid crystal displays. Methods such as sequential lateral solidification (SLS) use laser irradiation to fabricate high quality polycrystalline films with large, uniform crystal grains. However, the many iterative steps of irradiation and translation required impede high-throughput production. By providing methods that allow translation of both the film and the laser during irradiation, this technology allows complete crystallization of a thin film with a single scan.
