<p>A heat treatment apparatus for performing heat treatment of processing objects at a time without changing the interior configuration of a conventional clean room even when the processing objects are large-sized. The heat treatment apparatus is installed in a clean room. The heat treatment apparatus includes: a heat treatment furnace including a vertical processing chamber having a furnace opening at the top and adapted to house and heat-treat processing objects, a heat insulator that surrounds the circumference of the processing chamber, and a heater provided on the inner peripheral surface of the heat insulator; a lid for closing the furnace opening of the processing chamber; and a holding tool, hung via a heat-retaining cylinder from the lid, for holding the processing objects in multiple stages. The heat treatment furnace of the heat treatment apparatus, for the most part in the height direction, lies beneath the floor of the clean room.</p> |
