ABSTRACT:
A heat treatment apparatus achieves a uniform and rapid temperature rise of an object to be processed. A plurality of double-end lamps heat the object to be processed so as to apply a heat treatment process to the object. A plurality of reflectors reflect radiation heat of the double-end lamps toward the object to be processed. Each of the double-end lamps includes a rectilinear light-emitting part and at least two double-end lamps among the plurality of double-end lamps are arranged along a longitudinal direction of the light-emitting part, or each of the double-end lamps includes a rectilinear light-emitting part and the plurality of double-end lamps are arranged so that the light-emitting parts are parallel to each other and positioned in at least two stages.
