Abstract:
1. A projection exposure apparatus comprising: a projection exposure mask which includes a first mask pattern for exposing a member to form a continuous pattern thereon and a second mask pattern for exposing the member to form a discontinuous pattern thereon, one of the first and second mask patterns being a reflecting type mask and the other mask pattern being a transmitting type mask pattern; a projection system which projects light from the reflecting type mask pattern and light from the transmitting type mask pattern onto the member; a first illumination system which irradiates light to the reflecting type mask pattern from one side of the projection exposure mask; a second illumination system which irradiates light to the transmitting type mask pattern from the opposite side of the one side of the projection exposure mask; and a substrate stage which moves the member in a direction substantially orthogonal to a projection light axis of the projection system.
