Beschreibung
Zusammenfassung:	A method of forming a chemical mechanical polishing pad composite polishing layer is provided, including: providing a first polishing layer component of a first continuous non-fugitive polymeric phase having a plurality of periodic recesses; discharging a combination toward the first polishing layer component at a velocity of 5 to 1,000 m/sec, filling the plurality of periodic recesses with the combination; allowing the combination to solidify in the plurality of periodic recesses forming a second non-fugitive polymeric phase giving a composite structure; and, deriving the chemical mechanical polishing pad composite polishing layer from the composite structure, wherein the chemical mechanical polishing pad composite polishing layer has a polishing surface on the polishing side of the first polishing layer component; and wherein the polishing surface is adapted for polishing a substrate.
