Patent number: 11934126Abstract: A heating device includes a first rotator, a heater including a base and a heat generator, and a second rotator contacting the first rotator. The heat generator adjacent to the base defines a heat generation area having one edge close to one edge of the base in a longitudinal direction of the base. A length between the one edge of the base and the one edge of the heat generation area is longer than a length between the other edge of the base and the other edge of the heat generation area. The second rotator has one edge close to the one edge of the heat generation area. A length between the one edge of the second rotator and the one edge of the heat generation area is shorter than a length between the other edge of the second rotator and the other edge of the heat generation area.Type: GrantFiled: October 11, 2022Date of Patent: March 19, 2024Assignee: RICOH COMPANY, LTD.Inventors: Yasunori Ishigaya, Keitaro Shoji, Tomoya Adachi, Daisuke Hirano

Publication number: 20240071793Abstract: In a substrate processing apparatus according to the present invention, a heating mechanism for heating a substrate includes a gas discharge nozzle arranged in an internal space, a heater attached to an outer wall of a chamber, and a pipe feeding to the discharge nozzle. An observing mechanism includes a light source part and an image pickup part which are arranged at a separation position away from an attachment portion in the outer wall of the chamber. Thus, the light source part and the image pickup part become less susceptible to an effect of heat generated by the heater. In other words, it is possible to prevent the reduction in the observation accuracy due to an effect of temperature change.Type: ApplicationFiled: August 7, 2023Publication date: February 29, 2024Inventors: Shuhei NEMOTO, Kazuhiro SHOJI, Daisuke HISHITANI, Yusuke SATO, Tomomitsu NISHIMURA
