Abstract:
1. A heat transfer assembly of a substrate support for a substrate processing system, comprising: a heat spreading member that is sandwiched between a lower surface of a first contact plate and an upper surface of a second contact plate, the first contact plate having a lower surface that is thermally coupled to an upper surface of the heat spreading member, the second contact plate having an upper surface that is thermally coupled to a lower surface of the heat spreading member along a predominant portion of the lower surface of the heat spreading member, the heat spreading member having a greater thermal conductivity than the first and second contact plates, wherein the first contact plate is thermally coupled to a heat source disposed above the lower surface of the first contact plate, the second contact plate is thermally coupled to a heat sink along a predominant portion of a bottom surface of the second contact plate, and wherein the first and second contact plates reduce heat flux between adjacent components.
