Title: Hot plate type baking apparatus
Inventor: TANAKA TSUTOMU
IPC: H01L21/027
Filed: 1986-03-18
Abstract: PURPOSE:To eliminate damages on the back surface of a substrate and the front surface of a hot plate by supporting part of a semiconductor substrate at a predetermined position on the front surface of the hot plate to provide a recess for containing the substrate, thereby correctly setting the substrate on the plate. CONSTITUTION:A recess 2 of a lateral width size or slightly wider than the width is formed at a predetermined position on the front surface of each hot plate 1 of a baking apparatus, and the recess 2 is opened at the front and rear edges of the plate 1. Oblique surfaces 4, 4 for supporting the lower edge 5 of a substrate 3 inclined from the bottom are formed at the corners of the bottom of the recess 2. Accordingly, since the substrate 3 is supported at the lower edge 5 in a horizontal state to the oblique surfaces 4, 4 to be contained in the recess 2, the lateral displacement of the substrate 3 is restricted to be set at a predetermined position on the plate 3. Since the substrate 3 is supported at the lower edges 5 by the oblique surfaces 4, 4, no dust is inserted between the substrate 3 and the plate 1. Thus, the damages to the back surface of the substrate 3 and plate 1 can be eliminated.
