Abstract
A system for fabricating a semiconductor device structure includes a tool comprising a chamber and a platform within the chamber configured to receive a semiconductor device structure thereon. The tool further includes a heating and cooling system in operable communication with the platform and configured to control a temperature of the platform. The heating and cooling system comprises a cooling system including a cold tank for containing a cold thermal transfer fluid, the cold tank configured to be in fluid communication with the platform, thermal transfer fluid supply piping, and thermal transfer fluid return piping, a heating system including a hot tank for containing a hot thermal transfer fluid having a higher temperature than the cold thermal transfer fluid, the hot tank configured to be in fluid communication with the platform, the thermal transfer fluid supply piping, and the thermal transfer fluid return piping, and at least one temporary storage tank configured to receive at least some of the cold thermal transfer fluid or the hot thermal transfer fluid from at least the thermal transfer fluid return piping after switching a thermal load from the platform from one of the…
