Abstract

Rapid thermal cycling of substrates in low-pressure processing environments is achieved by movable temperature conditioners located outside the processing environments. The substrates are mounted on thermally conductive pedestals for processing in the low-pressure environment. The temperature conditioners are movable both into and out of thermal contact with the pedestals outside the low-pressure environment to regulate transfers of heat through the pedestals between the substrates and the temperature conditioners. A translatable cooler block with a high thermal mass and a large interface area with the pedestal can be used as a temperature conditioner for more rapidly withdrawing heat from the substrate.
