Abstract:
Exemplary substrate processing systems may include a body that defines processing and transfer regions. The systems may include a liner atop the body. The systems may include a faceplate atop the liner. The systems may include a support within the body. The support may be vertically translatable between process and transfer positions. The support may include a plate having a heater. The support may include a shaft coupled with the plate. The support may include a bowl about the shaft below the plate. The bowl may be in alignment with the liner. The support may include springs that push the bowl upward as the support translates to the process position. The support may include straps that couple the plate and bowl. The support may include a hard stop. The bowl may contact the liner in the process position and may be spaced apart from the liner in the transfer position.
