摘要:
Semiconductor device manufacturing equipment has a vacuum system that enhances the fluency of the gas being discharged from a chamber of the equipment. The vacuum system has a vent line, and a throttle valve that includes a vent line opening and closing member oriented so that it is readily opened by a concentrated flow of gas in the vent line. The vacuum system may include a heating unit that heats the vent line through which the gas passes. Still further, a bend in the vent line upstream of the vent line opening and closing member may have a gently curved shape and/or may subtend an angle of less than 90°. As a result, the efficiency of the ventilation of the process chamber is improved, making it easier to control the pressure of the process chamber and minimizing the contamination of the throttle valve and the vent line.
摘要:
Semiconductor device manufacturing equipment is installed using a mock-up of the equipment. First, a full-scale layout drawing of the equipment is prepared. Also, a mock-up of the equipment is fabricated. The mock-up has wiring and pipe connectors of the same type as those of the main equipment. The layout drawing is placed on the floor of the site at which the main equipment is to be installed. Then the mock-up is placed at the same location where the main equipment is to be installed, as represented in the layout drawing, with the wiring and pipe connectors of the mock-up located at the same positions where the wiring and pipe connectors of the main equipment will be located. The wiring and piping of the semiconductor manufacturing equipment is installed, and ends of the wiring and piping are connected to the wiring and pipe connectors of the mock-up. Then the wiring and piping are inspected. Subsequently, the mock-up is disassembled and removed, and the main equipment is set in place at the same location from which the mock-up was removed. Finally, the wiring and piping are connected with the wiring and pipe connectors of the main equipment. Thus, the semiconductor device manufacturing equipment can be quickly placed in operation once the main, apparatus of the equipment is procured.
