Abstract

An apparatus for heat treatment of a wafer. The apparatus includes a heating chamber having a heat source. A cooling chamber is positioned adjacent to the heating chamber and includes a cooling source. A wafer holder is configured to move between the cooling chamber and the heating chamber through a passageway and one or more shutters defines the size of the passageway. The one or more shutters are movable between an open position where the wafer holder can pass through the passageway and an obstructing position which defines a passageway which is smaller than the passageway defined when the shutter is in the open position.
