Abstract: PURPOSE: A method of growing a semiconductor thin film is to deposit amorphous silicon dopped high concentration impurity on a natural oxide film and accelerates decomposition of the oxide film with heat treatment, thereby reducing annealing temperature and increasing crystallizing ability and the decomposition of the oxide. CONSTITUTION: An amorphous silicon film(32) dopped high concentration impurity is deposited on a natural oxide(34) film of a substrate. The substrate deposited on the amorphous silicon film is annealed so that the natural oxide film is resolved and mono-crystallized. After mono-crystallizing the amorphous silicon, the annealing temperature is lowered and then a mono-crystalline silicon thin film(33) is deposited. In the depositing process, the amorphous silicon has a thickness of at least 20nm. The depositing process is performed at a temperature of below 500 deg.C. The impurity is an n type or a p type such as B, P, As and Sb. The annealing process is performed for few seconds at a temperature of at least 700 deg.C or more. The impurity is implanted with a concentration of 1x10¬19/cm8-5x10¬22/cm.

Abstract: PURPOSE: A vertical ultra-vacuum chemical deposition apparatus is provided to sufficiently improve productivity, by growing a high-quality thin film at a low pressure of 10¬-3 Torr and a low temperature of 500 deg.C and by simultaneously disposing 50 wafers. CONSTITUTION: A growth chamber(100) maintains uniformity of growth of an epitaxial layer at a high vacuum and minimizes heat transferred from a wafer, having a quartz tube of a dual structure. A wafer transfer chamber(200) includes a vertical transfer apparatus for vertically transferring the wafer in which the epitaxial growth layer is formed, connected to the lower portion of the growth chamber. A buffer chamber(300) prevents stress from being applied to a transfer gear by a pressure difference with a wafer transfer chamber in vertically transferring the wafer, installed in the lower portion of the wafer transfer chamber. A loadlock chamber(400) reduces contamination from the exterior in growing the epitaxial growth layer and horizontally transfers the wafer having the epitaxial growth layer to the exterior, connected to a side of the wafer transfer chamber.
