Abstract

An exposure device includes a laser source, a first spatial light modulator, a second spatial light modulator and a controller. The laser source is provided for emitting a laser. The first spatial light modulator is irradiated by the laser and used for modulating the phase of the laser irradiated on the first spatial light modulator before reflecting the laser. The second spatial light modulator is irradiated by the laser reflected from the first spatial light modulator and used for modulating the amplitude of the laser irradiated on the second spatial light modulator before reflecting the laser. The laser reflected by the second spatial light modulator is irradiated on a photoresist layer to form an exposure pattern.
