Title:
SUBSTRATE HEATING SYSTEM
Document Type and Number:
Japanese Patent JP3042229
Kind Code:
B2
Abstract:

PURPOSE: To provide a highly efficient downsized substrate heating system for heating a substrate, e.g. a semiconductor wafer, in vacuum while introducing a specific material gas thus forming a thin film on the substrate in which high temperature heating can be carried out for a long time while controlling the heating temperature accurately and easily.
CONSTITUTION: A plurality of circular infrared lamps having different diameters are arranged concentrically on a same plane to form a planar heater 5 having circular profile similar to that of a substrate 4. The substrate 4 is heated from the atmospheric side through a heating window 2 closing a vacuum vessel 1 containing the substrate 4 airtightly at the open end face thereof thus making a relatively wide space of the substrate 4 available at the central part of a temperature measuring heater.
