Aluminum Nitride

Aluminum Nitride

Aluminum Nitride substrates possess thermal gradient properties that allow for superior heat uniformity. These chemically "clean" substrates meet tough clean room environment requirements for the semiconductor, medical and other stringent applications. Heaters applied to this substrate are extremely versatile due to the ability to formulate heaters that have good mechanical strength with low inertial mass. Extremely powerful heaters from very small sizes can be fabricated with the ability to reach temperatures in excess of 500°C in a matter of seconds and cool down almost as rapidly. Heaters have been tested with watt densities of over 500 watts per square inch.
