Abstract: An apparatus includes a reaction chamber installed in a reaction furnace; a discharge port for removing from the reaction chamber reaction byproducts formed during producing of the semiconductor device; a heater for generating heat to the reaction chamber; and a hot fluid supply unit for introducing heat from the heater and the reaction chamber into the discharge port. The hot fluid supply unit further comprises a fluid container for receiving a heat transfer fluid. The apparatus includes a hot fluid generator adjacent the reaction chamber in the reaction furnace. The hot fluid generator defines a fluid channel for conveying the heat transfer fluid and transfers heat generated from the heater and the reaction chamber to the heat transfer fluid supplied from the fluid container. The apparatus also includes a heat transfer element for transferring heat to the discharge port using the heat transfer fluid supplied from the hot fluid generator.

Abstract: An apparatus for manufacturing a semiconductor device and a method of manufacturing a capacitor of a semiconductor device prevents the decrease of the surface area of a hemispherical grained (HSG) film formed on a lower electrode of the capacitor of the semiconductor device due to the abrasion of the HSG film during a subsequent cleaning process. The method of manufacturing a capacitor includes: forming a lower electrode of a capacitor of a semiconductor device over a specific structure formed on a semiconductor substrate; forming a hemispherical grained (HSG) film on an exposed surface of the lower electrode; stabilizing the HSG film in order to prevent the decrease of the surface area of the HSG film due to the abrasion of the HSG film during subsequent cleaning. The apparatus for manufacturing a semiconductor device includes a first process chamber for formation of the HSG film on a lower electrode of a capacitor of the semiconductor device and a second process chamber which stabilizes the HSG film.

Abstract: An apparatus for low pressure chemical vapor deposition for fabricating a semiconductor device comprises a group of reaction chambers, a group of high-vacuum pumps connected to the reaction chambers, a group of gate valves connected to the high-vacuum pumps, and a low-vacuum pump connected to the gate valves. There are fewer gate valves than high-vacuum pumps. A method for fabricating a semiconductor device using the above apparatus includes the sequence and duration of opening gate valves, injecting reaction gases, and pumping with the low vacuum pump. According to the present invention, since the number of pumps is reduced, the cost for installation, operation and maintenance of the semiconductor device fabrication apparatus is reduced.
