Abstract

A semiconductor device manufacturing method is provided for manufacturing semiconductor elements on a substrate through RTA (Rapid Thermal Annealing) using a lamp. A substrate is sequentially and preliminarily heated using a plurality of preliminary heating plates arranged for stepwise temperature rise before annealing the substrate using the RTA technique. After the heating process, a cooling step may be performed to the substrate to cool it stepwise. The annealing process can prevent a breakage in a substrate due to thermal stress, while the throughput increases.
