Abstract: The invention provides a substrate processing apparatus using a composite material which permits avoidance of occurrence of damages caused by the difference in thermal expansion between different materials and can be with stand the use at high temperatures. The substrate processing apparatus for processing a substrate is partially (for example, a substrate mounting stage) composed of a composite material 11 consisting of a matrix 12 comprising a ceramics member made of, for example, cordierite ceramics, aluminum nitride and/or a texture filled with an aluminum-based material (for example, aluminum or aluminum and silicon), and a ceramics layer (comprising, for example, Al2O3 and/or AlN) provided on the surface of the matrix 12.
