Abstract
Abstract A charge-coupled device package comprises a substrate of dielectric material and a charge-coupled device die mounted on one main face of the substrate. The substrate is placed in heat exchange relationship with a cold sink, such as a bath of LN 2 . A temperature sensor senses the temperature at a location on the main face that is in close proximity ot the die. A film resistor is adhered to the opposite main face of the substrate and receives a current that depends upon the temperature sensed by the sensor.
