Abstract:
1. A photo-induced process apparatus comprising: a reaction chamber housing comprising an upper plate including a first opening through which light is transmitted, and a support for supporting a sample or a substrate; a light source comprising a light emission plane that faces the first opening so that the light is irradiated into the reaction chamber through the first opening; a transparent film installation and storage chamber housing disposed between the light emission plane of the light source and the reaction chamber the transparent film installation and storage chamber housing comprising a lower plate and an upper plate, wherein the lower plate includes a second opening and the upper plate includes a third opening and wherein the lower plate of the transparent film installation and storage chamber housing is connected to the upper plate of the reaction chamber such that the first opening and second opening are aligned; a transparent film installed in the transparent film installation and storage chamber housing to prevent blurring of a light emission surface of the light source; a first flange having a fourth opening wherein an edge of the light emission plane of the light source is attached to the first flange along a perimeter of the fourth opening; a second flange which is connected along a perimeter of the third opening of the upper plate of the installation and storage chamber housing; an extension and contraction portion comprising upper and lower third flanges connected to end portions of the extension and contraction portion, wherein the upper third flange is connected to the first flange and wherein the lower third flange is connected to the second flange, wherein the reaction chamber housing, the transparent film installation and storage chamber housing, the extension and contraction portion, and the first flange with the light source, connected together form a single sealed space that can maintain a vacuum, and enable the light source to move up and down without breaking the vacuum; and a driving unit for moving the light source up and down.
