Abstract:
1. A process for selectively removing material from a substrate comprising at least one layer, the process comprising: providing the substrate having materials thereon to an assembly comprising at least one nozzle tip, wherein the nozzle tip comprises a proximal end, a distal end, and a longitudinal axis extending from the proximal end to the distal end, the proximal end having an opening defined by a first edge and a second edge, the first edge being at an angle of from about 20 degrees to about 120 degrees relative to the axis, and the second edge being at an angle of from about 15 degrees to about 70 degrees relative to the axis; contacting the at least one nozzle tip with the substrate such that at least one of the first edge or the second edge of the nozzle tip penetrates the materials on the substrate; and moving the assembly in relation to the substrate to skive at least a portion of the substrate in contact with at least one nozzle tip, the nozzle tip being capable of skiving cross-linked materials on the substrate and removing all desired material in a single pass.
