Abstract
Methods and systems for crystallizing a thin film provide an optics system configured to produce a laser spot beam directed towards the thin film and truncate the laser spot beam before the laser spot beam comes into contact with the thin film. The truncated laser spot beam is continually translated in a first direction while irradiating an amorphous silicon area of the thin film to generate a molten zone in the irradiated amorphous silicon area, where the thin film cools and solidifies to form crystal grains.
