Patent ID: 7980003

Claim:
A heat processing method using a heat process by use of a heat processing apparatus, which comprises a heating plate configured to heat a substrate, a cover configured to surround a space above the heating plate, a first gas flow forming mechanism configured to form first gas flows within the space above the heating plate, and a second gas flow forming mechanism configured to form second gas flows within the space above the heating plate, the method comprising: placing a target substrate on the heating plate and surrounding the space above the heating plate by the cover; and then performing a heat process on the target substrate by heating the target substrate by the heating plate, wherein the heat process is performed along with first and second states of gas flows sequentially set in this order while heating the target substrate by the heating plate, the first state uses the first gas flow forming mechanism to form, as the first gas flows, downward flows of gas uniformly supplied onto an upper surface of the target substrate to uniformize the heat process over the target substrate, and the second state uses the second gas flow forming mechanism to form, as the second gas flows, sideward flows of gas along the upper surface of the target substrate by exhausting gas from the space above the heating plate to exhaust and remove at least one of gas and sublimed substances generated from the target substrate.
