Substrate treatment installation with adjustable thermal insulation for controlling substrate temperature

A substrate treatment installation comprising:

• a vacuum chamber, a substrate treatment device within the vacuum chamber, a substrate transport device within the vacuum chamber for transporting a substrate along a longitudinal direction in a substrate transport plane past the substrate treatment device, and a substrate temperature controlling device within the vacuum chamber for controlling temperature of the substrate, the substrate temperature controlling device comprising cooling means for absorbing heat on one side of the substrate transport plane, and insulation means selectively displaceable between at least two different operative positions to vary extent of thermal shielding of the cooling means relative to the substrate transport plane, by the insulation means.
