Abstract:
1. A substrate processing apparatus comprising: a light receiving chamber configured to process a substrate; a substrate support unit disposed inside the light receiving chamber to support the substrate; a lamp including: a lamp electrical wire; and a sealing part accommodating the lamp electrical wire therein to hermetically seal the lamp with a gas therein, the lamp being configured to irradiate the substrate supported by the substrate support unit with a light; a lamp receiving unit disposed outside the light receiving chamber to accommodate the lamp therein, the lamp receiving unit including: a lamp connection member connected to the lamp to supply an electric current through the lamp electrical wire; a heat absorption member covering the sealing part to absorb heat from the sealing part, the heat absorption member including a material having a thermal conductivity higher than that of the sealing part; and a base member fixing the heat absorption member, wherein the lamp connection member and the heat absorption member are inserted in the base member; and an external electrical wire connected to the lamp connection member to supply an electric current to the lamp connection member, wherein the sealing part of the lamp is covered by the heat absorption member, and wherein the heat absorption member covers the external electrical wire and is in contact with the external electrical wire.
