ABSTRACT:
An integrated circuit (IC) temperature sensing device includes a temperature sensor positioned within a conductive temperature sensor housing and a thermal insulator surrounding the conductive temperature sensor housing. The sensor housing and thermal insulator are positioned within an IC temperature control block that heats or cools the IC. The temperature sensor housing comes into thermal contact with an IC undergoing burning-in, testing or programming. The temperature sensor housing provides a short thermal path between the IC under test and the temperature sensor. The thermal insulator thermally isolates the temperature sensor from the temperature control block so that the temperature sensor predominantly measures the temperature of the IC. The method of sensing the temperature of an IC includes actively changing the temperature of an IC with a heater or cooler, sensing the temperature of the IC with a temperature sensor positioned within a conductive sensor housing in thermal contact with the IC and thermally insulating the sensor housing and temperature sensor from the heater or cooler.
