Patent number: 10106914Abstract: The present disclosure controls the heat source unit such that a to-be-processed object in which a hydrogen-containing to-be-processed layer is formed is irradiated with light in two stages, and thus the electrical characteristics of a semiconductor device may be suppressed and prevented from being deteriorated due to hydrogen. That is, ultraviolet light (UV) which is firstly radiated may induce a chemical reaction for separating Si—H bonds in the to-be-processed layer, and infrared light (IR) which is secondly radiated may induce a thermal reaction for vaporizing the separated hydrogen from the Si—H bonds. As such, both a chemical reaction for separating bonds of hydrogen and other ions in the to-be-processed layer and a thermal reaction for vaporizing hydrogen are performed, and thus hydrogen may be more easily removed than a temperature at which hydrogen is vaporized from the to-be-processed layer by only a thermal reaction.Type: GrantFiled: March 25, 2016Date of Patent: October 23, 2018Assignee: AP SYSTEMS INC.Inventors: Pil Seong Jeong, Sang Hyun Ji, Sung Yong Lee, Yong Woo Han
