Title: Crystallization method for semiconductor film and manufacturing method for semiconductor device

Filed: 2008-01-11
Abstract: <P>PROBLEM TO BE SOLVED: To uniformize plane orientation of crystal grains of a semiconductor film cristallized by irradiation with a linear laser beam, and to manufacture with a high yield, a crystalline semiconductor wherein the plane orientation of crystal grains is uniform.  <P>SOLUTION: A base insulating film, a semiconductor film and a cap film are formed on a substrate. A laser beam oscillated from a laser such as a continuous oscillation laser is converged to the linear laser beam having a width of 5 μm or less by a cylindrical lens of aspheric surface or a gradient index lens. By applying the linear laser beam to completely melt the semiconductor film, and scanning with the linear laser beam, the completely-melted semiconductor film is lateral-grown. Since the width of the linear beam is so narrow as to have 5 μm or less, the width of the semiconductor in a liquid form also has narrow width, and generation of turbulent flow in the semiconductor in the liquid form is suppressed. Thereby, a growth direction of adjoining crystal grains is uniformized without disturbance, so that plane orientation of the lateral-grown crystal grains is uniform.  <P>COPYRIGHT: (C)2008,JPO&INPIT
