ABSTRACT:
An ultraviolet irradiating apparatus for emitting ultraviolet light toward a work piece. The work piece, e.g. a semiconductor wafer, is held by a ring-shaped frame through an ultraviolet sensitive adhesive tape applied to the back surface of the wafer. The apparatus includes an ultraviolet irradiating section having a regulating member disposed in a lower position of a support base. The regulating member is provided to limit a downward displacement of the wafer.
