Abstract:
An apparatus for heating and cooling one or more semiconductor devices in a handler for testing semiconductor devices, the apparatus comprising:a mounting plate comprising a plurality of recesses configured to receive the one or more semiconductor devices; a heating plate installed adjacent to a lower surface of the mounting plate, wherein the heating plate comprises at least one heater installed therein, and wherein the heating plate is configured to provide heat to the mounting plate; a cooling plate installed adjacent to a lower surface of the mounting plate comprising a flow groove wherein a depth of the flow groove increases as the flow groove travels from an inlet thereof to an outlet thereof and wherein the flow groove is configured to receive cooling fluid from an external cooling fluid supply source, to distribute the cooling fluid throughout the cooling plate so as to uniformly cool the cooling plate, and to discharge the cooling fluid to an area outside of the cooling plate; a heating control device configured to control a level of heat provided by the heater and to control a heating temperature of the mounting plate; and a cooling control device configured to control an amount of cooling fluid fed to the cooling plate and to control a cooling temperature of the mounting plate.
