Patent number: 8317966Abstract: Conditioning fluid flow into a proximity head is provided for fluid delivery to a wafer surface. An upper plenum connected to a plurality of down flow bores is supplied by a main bore. The down flow bores provide fluid into the upper plenum, and a resistor bore is connected to the upper plenum. The resistor bore receives a resistor having a shape so as to limit flow of the fluid through the resistor bore. A lower plenum connected to the resistor bore is configured to receive fluid from the resistor bore as limited by the resistor for flow to a plurality of outlet ports extending between the lower plenum and surfaces of the head surface. Fluid flowing through the upper plenum, the resistor bore with the resistor and the lower plenum is substantially conditioned to define a substantially uniform fluid outflow from the plurality of outlet ports, across the width of the proximity head.Type: GrantFiled: February 7, 2009Date of Patent: November 27, 2012Assignee: Lam Research CorporationInventors: Arnold Kholodenko, Cheng-Yu (Sean) Lin, Russell Martin
