SUBSTRTE SUPPORT STRUCTURE, HEAT TREATMENT APPARATUS USING SAME, FIRST SHEET-LIKE OBJECT FOR USE IN THE SUBSTRATE SUPPORT STRUCTURE, METHOD OF MANUFACTURING THE SUBSTRATE SUPPORT STRUCTURE, HEAT TREATMENT APPARATUS, AND SUBSTRATE SUCKING METHOD

摘要

A heat treatment apparatus includes a support sheet placed on an upper surface of a heat-treating plate. The support sheet has, formed on an upper surface thereof, projections for contacting and supporting a substrate, and a lip for contacting edge regions of the substrate. The support sheet is formed by an etching process, and therefore areas of the sheet around the projections are recessed, rather than being perforated as in the case of laser processing. These heat-treating plate and support sheet constitute a substrate support structure capable of supporting the substrate properly.
