Abstract

We report a new non-invasive optical technique for the measurement of the absolute temperature of silicon wafers in a rapid thermal processing environment. The method is based on the temperature dependence of the infrared absorption of silicon. Unlike pyrometry, the method can be used with a quartz processing chamber, and it is well-suited to the temperature range of 400 °C to 800 °C. Temperature resolution on the order of one degree can be achieved, and the method can easily be applied to homoepitaxial and certain heteroepitaxial growth cycles.
