Aluminum Nitride substrates possess thermal gradient properties that allow for superior heat uniformity. These are chemically "clean" substrates meeting the tough clean room environment for the semiconductor, medical and other very stringent applications. Heaters laid down on this substrate are extremely versatile due to the ability to formulate heaters that have good mechanical strength with low inertia mass. Extremely powerful heaters from very small sizes (0.05 sq.in. to approximately 40 sq.in.) can be fabricated with the ability to reach temperatures in excess of 500°C (for short repetative cycles) 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.
