Latest Patents
One of Ming-Hong Lee's latest patents focuses on "Thin film crystal growth by laser annealing." This innovative process involves transforming a layer of material from a first state to a second state through the application of energy from an energy beam. Specifically, it utilizes large direction- and location-controlled p-Si grain growth, which is achieved by recrystallizing amorphous silicon through superpositioned laser irradiation. The method employs a first laser beam to melt an amorphous silicon (a-Si) film, creating a temperature gradient. After an initial delay, a second laser beam with a shorter pulse duration is superpositioned with the first beam. This technique allows for spontaneous nucleation in the supercooled liquid-Si when the temperature drops below the nucleation threshold. The process is carefully controlled to ensure that grains nucleated in the periphery can grow into the liquid-Si, ultimately leading to the desired crystal structure.
