Abstract

Provided are a heating device, a substrate processing apparatus, and a method of manufacturing a semiconductor device. The heating device comprises: a heating element including a mountain part and a valley part that are alternately connected in plurality in a meander shape with both ends being fixed; holding body receiving parts respectively installed at ends of the valley parts and formed as cutout parts having a width larger than a width of the valley part; an insulating body installed at an outer circumference of the heating element; a holding body disposed in the holding body receiving part and fixed to the insulating body; the heating element having a ring shape; the insulating body installed in a manner of surrounding the outer circumference of the heating element; and a fixation part configured to fix the heating element to an inner wall of the insulating body.

Description

technical field [0001] The present invention relates to a heating device, a substrate processing device for processing a substrate, and a method of manufacturing a semiconductor device. Background technique [0002] As one step of a method of manufacturing a semiconductor device such as a DRAM, a substrate processing step of heating and processing a substrate such as a silicon wafer is performed. This step is carried out by a substrate processing apparatus having a processing chamber for accommodating and processing a substrate, and a heating device for heating the processing chamber. The heating device has an annular heat generating body surrounding the periphery of the processing chamber and an annular heat insulator provided on the periphery of the heat generating body. On the upper and lower ends of the heating element, a plurality of peaks and valleys (notches) are alternately connected, whereby the heating element is formed in a meandering shape (for example, refer to...
