Zusammenfassung: | A heat shield plate for a substrate annealing apparatus is provided with a horizontally supported flat-plate-like substrate 1, a heater 5 positioned above the substrate to heat the upper surface of the substrate with radiation heat, and a heat shield plate 10 horizontally movable between a shielding position where the substrate is shielded from heater and an open position out of the shielding position. The heat shield plate 10 is composed of a structural member 12 made of a low thermal expansion material (carbon composite material) which is hardly deformed due to a temperature difference in the shielding position, and a heat insulating member 14 which covers the upper surface of the structural member and keeps the surface at an allowable temperature or below. |
