Abstract:
1. Dynamic burn-in equipment for conducting burn-in of semiconductor devices while burn-in signals are input to the semiconductor devices and the semiconductor devices are, accommodated in a burn-in chamber, the equipment comprising: an infrared measuring unit measuring surface temperatures of certain semiconductor devices among the semiconductor devices; and a control unit controlling the temperature inside the burn-in chamber to make an average internal temperature Tj of said certain semiconductor devices equal to a predetermined value, where Tj is calculated according to the sum of an average surface temperature Ts and a temperature difference ΔTj, wherein Ts is an average of the surface temperatures measured by the measuring unit, and ΔTj is a temperature difference between Tj and Ts that is obtained from the expression “(power source voltage)×(power source current)×(thermal resistance value of the semiconductor devices)”.
