Abstract
The present invention relates to an exposure device for forming circuit patterns onto a surface of an object. The exposure device includes at least one spatial light modulator which includes a plurality of reflection elements being arranged in a matrix fashion, at least one optical source which supplies exposure light to the reflection elements, and a bias voltage controller which applies a first voltage to the reflection elements, thereby setting the reflection elements to a first state and which does not apply a voltage to the reflection elements, thereby setting the reflection elements to a second state. In addition, the exposure light is delivered to the surface of the object in the first state, and the exposure light is not delivered to the surface of the object in the second state.
