A linear motor apparatus includes a movable member having a magnet, and a coil wound about the magnet so as to generate a drive force for driving the movable member and having a multi-layer structure formed by winding a foil-like conductor and an insulating layer. The foil-like conductor (i) has a plurality of partial coils having identical current application/rotation directions, and the plurality of partial coils are formed in such a way that the foil-like conductor forms a continuous, seamless strip, and (ii) is continuously wound in a multilayered, aligned state to form the coil, and adjacent layers of the foil-like conductor are insulated by the insulating layer.

Some of linear motors which constitute an exposure apparatus have coils each obtained by winding a copper foil wire as a foil-like conductor having an insulating layer around a core member in a multilayered structure. The coil is fixed to a positioning portion serving as the coil fixing portion of the linear motor by using the core member. The core member is formed from the same insulating material with low thermal conductivity as that of the positioning portion of a linear motor housing or a material with almost the same linear expansion coefficient.

An exposure apparatus includes a projection device for projecting a pattern drawn on a surface of a master, a stage apparatus which moves at least a substrate of the master and a substrate relative to the projection device, and an exposure device for repeatedly exposing the substrate to the pattern of the master. A plurality of pipes connected to movable units of the stage apparatus are joined to each other at partial outer surfaces of the pipes and constitute an integrated pipe array. Electrical cables or signal line cables connected to the movable unit pass through hollow portions of some of the pipes serving as the integrated pipe array.
