VIEW PORT AND INGOT GROWING APPARATUS INCLUDING THE SAME

摘要

The present invention relates to a view port and an ingot growing apparatus comprising the same. The view port comprises: a body part communicated with an inner chamber; a first window arranged on the body part and transmitting lights inputted from the outside of the chamber; a window purge mounting the first window and forming an air curtain by using gas sprayed internally; and a second window disposed between the window purge and the body part and fixed by an intermediate structure. It is possible to prevent contamination sources from being deposited to the inner wall of the chamber and the first window as the flow of the sprayed gas is circulated easily in a lower portion of the first window, and the sprayed gas is concentrated to be discharged into the inner chamber through the second window.
