Abstract
A crystallizing method of causing a phase shifter to phase-modulate a laser beam whose wavelength is 248 nm or 300 nm or more from an excimer laser unit into a laser beam with a light intensity profile having a plurality of inverted triangular peak patterns in cross section and of irradiating the pulse laser beam onto a substrate to be crystallized for crystallization. The substrate to be crystallized is such that one or more silicon oxide films which present absorption properties to the laser beam and differ in the relative proportions of Si and O are provided on a laser beam incident face.
