Abstract

The invention provides a gas supply system of a semiconductor manufacturing device and a gas supply integration unit. The gas supply system is used for supplying predetermined gas from a gas supply source to a processing part of a semiconductor manufacturing device. The gas supply system is provided with a gas supply flow path connected to the gas supply source and the processing part. The gas supply flow path comprises a plurality of fluid control devices (hand valve, reducing valve, manometer, check valve, first stop valve, second stop valve, quality flow controller and gas filter) and flow path components connected between the fluid control devices and forming gas flow paths. The flow path components are made of carbon material. Thereby, when corrosive gas is supplied to the processing part, mixing of metallic pollutants relative to a substrate to be processed may be inhibited.

Description

[0001] This patent application claims the priority of Japanese Patent Application No. 2007-045973 filed on February 26, 2007 as a Japanese application. The entire disclosure content of this prior application is incorporated by reference as a part of this specification. technical field [0002] The invention relates to a gas supply system and a gas supply integrated unit of a semiconductor manufacturing device. Background technique [0003] For example, a semiconductor manufacturing apparatus such as a diffusion apparatus, an etching apparatus, or a sputtering apparatus has a gas supply system for supplying gas from a processing gas supply source such as a gas cylinder to a processing unit. Then, by performing a process for manufacturing a semiconductor device using a gas supplied from the gas supply system, for example, a film forming process and an etching process using a predetermined gas, surface treatment is performed on a substrate to be processed such as a semiconducto...
