Abstract:
An exposure apparatus for projecting a mask pattern of a mask onto a photosensitive substrate, said exposure apparatus comprising:a substrate stage which is two-dimensionally movable along an upper surface of a substrate base while carrying said photosensitive substrate thereon;substrate stage cable-relaying means for securing thereto a cable connected to said substrate stage and being movable in the same two-dimensional directions as those of said substrate stage;supporting means for supporting said substrate stage cable-relaying means;vibration insulating means for insulating vibration that transfers from said supporting means to said substrate base; andfirst driving means for controlling an amount of movement of said substrate stage cable-relaying means such that relative positions of said substrate stage and said substrate stage cable-relaying means with respect to each other are always kept constant.
