Method and apparatus for controlling sample temperature

摘要

This invention relates to a method and apparatus for controlling temperature of a sample and is intended to prevent a sample from being deformed by the pressure of a heat transmission gas by mounting and fixing the sample being mounted and processed in a vacuum on and to the sample stand and supplying the heat transmission gas to the gap between the under surface of the sample thus fixed and the sample stand; effectively control the temperature of the sample being processed in a vacuum by limiting the size of the gap between the under surface of the sample and the sample stand; and make the heat transmission gas least affect the process by limiting the flow of the heat transmission gas in the vacuum process chamber.
