Abstract

Provided is a raw gas supply system (6) for supplying a raw gas to a gas using system (2) set in a pressure-reduced atmosphere. The system comprises a material tank (40) for reserving a liquid material or a solid material, a material passage (46) connected at its one end to the material tank and at its other end to the gas using system, a carrier gas supply mechanism (54) for supplying a carrier gas to the inside of the material tank, ON / OFF valves (48 and 50) disposed midway of the material passage, a heater (64) for heating the material passage and the ON / OFF valves, and a temperature control unit (92) for controlling the heater. The material passage and the ON / OFF valves are formed of a metal material having an excellent heat conductivity.

Description

technical field [0001] The present invention relates to a film forming device for forming a thin film on the surface of a target object such as a semiconductor wafer, and a supply system for supplying a raw material gas thereto, and particularly relates to a device for supplying a useful semiconductor device by vaporizing a raw material with a low vapor pressure and not easily evaporated. Supply system of raw material gas and film forming device. Background technique [0002] Generally, when manufacturing a semiconductor device, in order to manufacture a desired device, various processes such as film formation and pattern etching are repeatedly performed on a semiconductor wafer. Nowadays, in accordance with the demands for higher integration and high miniaturization of semiconductor devices, both the line width and aperture are becoming finer. For wiring materials and embedding materials, it is necessary to further reduce the resistance due to the miniaturization of variou...
