Patent ID: 8496780

Claim:
An apparatus for depositing a film, the apparatus comprising: a chamber body having a processing region defined therein; a first vaporizer; a vapor delivery system connecting the first vaporizer and the processing region with a first vapor path of less than approximately three feet from the first vaporizer through the vapor delivery system to the processing region; a chamber lid disposed on the chamber body; a showerhead coupled to the chamber lid; and a seal interfacing with the chamber body and the chamber lid, wherein the chamber lid further comprises: a body having an inner body region and a circumscribing outer body region; a first temperature control zone defined in the outer body region and in thermal contact with the seal, the first temperature control zone including an annular coolant fluid passageway disposed radially outward of the showerhead and proximate an outer perimeter of the chamber lid and the seal; and a second temperature control zone defined in the inner body region, the second temperature control zone abutting and in thermal communication with the processing region and the first temperature control zone, the second temperature control zone including an annular resistive heater disposed radially inward of the coolant fluid passageway and above the showerhead, the resistive heater disposed in an annular groove formed in a top of the chamber lid, the groove formed radially inward of an outer edge of the showerhead.
