Abstract:
1. A method of configuring a proximity head to transfer fluid through a plurality of fluid transfer flow paths in the head and onto a surface of a semiconductor wafer, the method comprising: (a) providing a first block with a first mating surface; (b) providing a second block with a second mating surface; (c) performing a first series of operations in the first block, the first series of operations including: (d) performing a second series of operations in the second block, the second series of operations including: (e) fusing the first and second mating surfaces to render the first and second blocks unitary with the plenum open to and between both the plurality of fluid transfer bores and the cross-shaped cross-section of the high resistance fluid flow path, the fusing defining the proximity head used to transfer fluids to the surface of the semiconductor wafer.
