Abstract

A method for crystallizing a semiconductor thin film is provided. The method includes continuously irradiating an energy beam on a semiconductor thin film while scanning at a given speed. The energy beam is scanned in parallel lines while keeping pitches of not larger than an irradiation radius of the energy beam to grow band-shaped crystal grains in a direction different from a scanning direction of the energy beam.
