Title:
MIXTURE GAS SUPPLY DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/101934
Kind Code:
A1
Abstract:
Disclosed is a mixture gas supply device for a semiconductor manufacturing device that prevents despread of other gas types toward the process gas supply line, and facilitates acceleration of gas exchange of the manifold and the process chamber of the mixture gas supply device. In a mixture gas supply device, a plurality of gas supply lines, comprising flow volume control devices and outlet-side switching valves (VO), are positioned in parallel arrangement, linking the gas outlets of each respective outlet-side switching valve (VO) to a manifold (1), and the gas supply line in a location near a mixed gas outlet of the manifold (1) is made so as to supply low flow volume gas. The outlet side of the flow volume control devices and the intake side of the outlet-side switching valves (VO) are linked in an airtight manner via mounts (19), further comprising flow volume control device outlet-side linking fittings (22) and gas paths (19a). Small hole portions (26) are disposed in some flow paths (24) upon the outlet-side linking fittings (22), and/or in flow paths (25) that communicates with the outlet-side switching valves (VO) and mixed gas flow through holes (20) of the manifold (1). It is possible to prevent despread of other gases to the upstream side of either the outlet-side switching valves (VO) or the flow volume control devices, and to rapidly substitute gas to the process chamber (6) that links to the mixed gas outlet (2) of the manifold (1).
