20090201622 | Detachable electrostatic chuck for supporting a substrate in a process chamber - A substrate support has an electrostatic chuck comprising an electrostatic puck with a dielectric covering an electrode capable of being charged to energize a process gas. The chuck has a frontside surface to receive a substrate and a base plate having an annular flange. A spring loaded heat transfer plate contacts the base plate, and has a fluid channel comprising first and second spiral channels. A pedestal is below the heat transfer plate. | 08-13-2009 |
20110017424 | HEAT EXCHANGE PEDESTAL WITH COATING OF DIAMOND-LIKE MATERIAL - A substrate heat exchange pedestal comprises: (i) a support structure having a contact surface comprising a coating of a diamond-like material, and (ii) a heat exchanger in the support structure, the heat exchanger capable of heating or cooling a substrate. | 01-27-2011 |
20130153412 | APPARATUS FOR ENABLING CONCENTRICITY OF PLASMA DARK SPACE - In some embodiments, substrate processing apparatus may include a chamber body; a lid disposed atop the chamber body; a target assembly coupled to the lid, the target assembly including a target of material to be deposited on a substrate; an annular dark space shield having an inner wall disposed about an outer edge of the target; a seal ring disposed adjacent to an outer edge of the dark space shield; and a support member coupled to the lid proximate an outer end of the support member and extending radially inward such that the support member supports the seal ring and the annular dark space shield, wherein the support member provides sufficient compression when coupled to the lid such that a seal is formed between the support member and the seal ring and the seal ring and the target assembly. | 06-20-2013 |
20140326184 | COOLING PEDESTAL WITH COATING OF DIAMOND-LIKE CARBON - A cooling pedestal for supporting a substrate, comprises a support structure having cooling conduits to flow a fluid therethrough to cool the substrate, and a contact surface comprising a coating of a diamond-like carbon. The coating comprises (i) a coefficient of friction of less than about 0.3, (ii) an average surface roughness of less than about 0.4 micrometers, and (iii) a microhardness of at least about 8 GPa. | 11-06-2014 |
