Abstract:
1. A scanning exposure apparatus using a microlens array, comprising: a microlens array being arranged above a substrate to be subjected to exposure and having a plurality of unit microlens arrays arranged by being stacked on top of one another, the unit microlens arrays configured having each of a plurality of microlenses arranged two-dimensionally therein; a mask arranged above the microlens arrays and having a prescribed exposure pattern formed thereon; an exposure light source for irradiating an exposure light on the mask; and a movement member for moving at least a portion of the unit microlens arrays so that the optical axis of the component microlenses thereof is shifted relative to the other unit microlens arrays, wherein the exposure position on the substrate is adjusted using the microlens array by shifting the optical axis between the unit microlens arrays, and wherein the microlens array is configured from four unit microlens arrays, and is configured to shift the microlens optical axis between the unit microlens arrays of a first layer and a second layer, and the unit microlens arrays of a third layer and a fourth layer.
