Abstract
A heat treatment unit comprises a heat plate made of aluminum nitride which is excellent in heat conductivity and strength inside thereof. The entire circumference of the heat plate is supported by a supporting member which is excellent in thermal insulation. The heat treatment unit is equipped with a nozzle for blowing dry air against the reverse side of the heat plate. When a temperature of the heat plate is lowered, the dry air is blown from the nozzle, thereby quickly lowering the temperature of the heat plate.
