Abstract: In a continuous processing system, a controller of a heat treatment apparatus calculates a weight of each layer from input target film thicknesses of a phosphorous-doped polysilicon film (D-poly film) and an amorphous silicon film (a-Si film), and calculates activation energy of stacked films based on the calculated weight and activation energy. The controller prepares a stacked film model based on the calculated activation energy and a relationship of a temperature of each zone and film thicknesses of the D-poly film and the a-Si film, and calculates an optimum temperature of each zone by using the prepared stacked film model. The controller controls power controllers of heaters to set a temperature in a reaction tube to be the calculated temperature of each zone and forms stacked films on a semiconductor wafer by controlling a pressure adjusting unit, flow rate adjusting units, etc.

Abstract: A collecting unit is disposed on an exhaust passage of a semiconductor processing apparatus to collect by-products contained in an exhaust gas. The collecting unit includes a trap body detachably disposed inside a casing and configured to collect a part of the by-products. The trap body includes fins arrayed in a flow direction of the exhaust gas and having a surface on which a part of the by-products is deposited and trapped. The collecting unit further includes a receiving mechanism disposed inside the casing and configured to receive a part of the by-products that peels off from the trap body or an inner surface of the casing to prevent this part from being deposited on a bottom of the casing. The receiving mechanism is configured to allow a part of the by-products held thereon to be in contact with a cleaning gas from above and from below.
