Abstract:
1. An exposure apparatus, which forms an exposure pattern on functional patterns formed on a surface of an object to be exposed corresponding to a plurality of mask patterns formed on a photomask by intermittently applying exposure light to the object to be exposed through the photomask each time the object to be exposed moves by a distance equal to an arrangement pitch of the functional patterns in a conveying direction while conveying the object to be exposed in the conveying direction, wherein the photomask is provided with a plurality of mask pattern columns formed by arranging the plurality of mask patterns in a line at a predetermined pitch in a direction substantially orthogonal to the conveying direction of the object to be exposed and formed at a pitch equal to an integral multiple of the arrangement pitch of the functional patterns in the same direction as the conveying direction of the object to be exposed, and a plurality of microlenses formed on a side of the object to be exposed corresponding to the mask patterns of the plurality of mask pattern columns to project reduced mask patterns on the object to be exposed, in which a subsequent mask pattern column and the microlenses corresponding to the column are formed so as to be shifted by a predetermined dimension in an arranging direction of the plurality of mask patterns such that it is possible to perform exposure by complementing a space between a plurality of exposure patterns formed by the mask pattern column located downstream in the conveying direction of the object to be exposed with a plurality of exposure patterns formed by the subsequent mask pattern column.
