Abstract:
1. A heat treatment system for a semiconductor device, the heat treatment system comprising: a loading unit for conveying the semiconductor device and a support plate, on which the semiconductor device is rested, after preheating the semiconductor device and the support plate at a predetermined preheating temperature, wherein the loading unit includes a susceptor, which has at an upper center portion thereof insulative slots and on which the support plate is placed, a heating device for heating the susceptor, a lifting device for moving the susceptor up and down, and a horizontal conveyance device for horizontally moving the support plate; a heating unit including at least two furnaces, the temperatures of which are individually controlled and increased step by step up to a predetermined heat treatment temperature for the semiconductor device, wherein the semiconductor device is adapted to be conveyed to the heating unit from the loading unit and heated at the predetermined heat treatment temperature by the heating unit; a cooling unit including at least two furnaces, the temperatures of which are individually controlled and decreased step by step and between the predetermined heat treatment temperature and a predetermined cooling temperature, wherein the semiconductor device is adapted to be conveyed to the cooling unit from the heating unit and cooled at the predetermined cooling temperature by the cooling unit; and an unloading unit for discharging the semiconductor device, after uniformly cooling the semiconductor device at a predetermined unloading temperature.
