Claim Text:
1. A light-exposure device, comprising: a light source for emitting pulsed laser light; a mask on which a pattern to be exposed is formed; a microlens array on which a plurality of microlenses for resolving an upright equal-magnification image on a substrate is aligned in a first direction, being a horizontal direction, and is provided in a plurality of rows at a prescribed horizontal pitch in a second direction, being a vertical direction; an optical system for guiding the laser light from said light source through said mask to said microlens array; a drive device for moving said substrate in said second direction relative to said mask and said microlens array; a switch device for shifting and successively switching a relative positional relationship between said microlens array and said mask in said second direction by an amount of said horizontal pitch of said microlenses; and a controller for controlling the movement of said substrate by said drive device, the switching of the relative positional relationship between said microlens array and said mask by said switch device, and a timing of irradiation with said laser light, wherein said controller successively repeats the following procedures so that the exposure pattern of said mask is transferred to an entirety of the exposure region of said substrate:
