Patent attributes
Heater module, and semiconductor manufacturing equipment in which the heater module is utilized, for raising the cooling speed of a post-heating heater markedly more than conventional, and that can contribute toward bettering and improving productivity, without accompanying scaling-up of and cost increases in the semiconductor manufacturing equipment. The heater module is furnished with heater part 1a for controlled heating of a wafer placed on its top face, and block part 3a provided to be shiftable relative to said heater part, for varying heat capacity in total with heater part 1a by abutting on or separating from the reverse surface of heater part 1a. By having the heat capacity of block part 3a be 20% or more of the total heat capacity of heater part 1a and block part 3a, the heater cooling speed can be made 10° C./min or more.
