Abstract:
1. A vacuum-processing method using a vacuum-processing apparatus comprising a vacuum vessel whose inside being capable of being evacuated, a processing chamber arranged in said vacuum vessel and a heater for heating a circumferential wall of said processing chamber, a cooling plate located outside the processing chamber and arranged at a position to oppose said circumferential wall of said processing chamber for cooling said circumferential wall of said processing chamber, and a mechanism for moving said cooling plate so as to change a distance between said cooling plate and said circumferential wall of said processing chamber, characterized in that said vacuum-processing method comprises the steps of (a) arranging a substrate in said processing chamber, (b) subjecting said substrate arranged in said processing chamber to a surface treatment while maintaining said substrate at a prescribed temperature and introducing a processing gas into said processing chamber, and (c) restraining a temperature rise of said circumferential wall of said processing chamber which is occurred in said step (b), by virtue of a heat exchange action between said cooling plate and said circumferential wall of said processing chamber.
