Patent ID: 8178821

Claim:
A substrate treating apparatus for treating substrates with a treating liquid, comprising: a treating tank for storing the treating liquid, and treating the substrates as immersed in the treating liquid; a chamber surrounding said treating tank; a supply device for supplying an inert gas containing an organic solvent into said chamber; a lift mechanism vertically movable, while supporting the substrates, between a process position in said treating tank and a wait position above said treating tank and inside said chamber; a tank temperature control device arranged and operable for heating said treating tank and having a tank temperature control jacket attached to outer surfaces of said treating tank; a chamber temperature control device for controlling temperature of said chamber; and a control device configured for causing said tank temperature control device and said chamber temperature control device to perform heating treatment, with the substrates being immersed in the treating liquid stored in said treating tank, at least while the inert gas containing the organic solvent is supplied from said supply device; wherein said tank temperature control jacket includes three temperature control attachments substantially U-shaped in plan view and thereby shaped to match shapes of a pair of opposite side surfaces and of a front surface of said treating tank, said three temperature control attachments being attached in contact with said side surfaces and said front surface of said treating tank.
