Heat treatment device

摘要

A heat treatment device comprises a table of a thermal conductor located in a housing carrying an object of treatment thereon, and a treatment heat source located in the housing and by the table so that a bottom face of the table is opposite to a top face of the heat source, whereby the object of treatment in heat-treated through the table. An annular groove is formed in the top face of the heat source and evacuated so that the substrate and heat source are securely attached thereby increasing the heat conduction between them.
