DEFINITION

Classification: 505/410

With material removal by etching, laser ablation, or mechanical abrasion:

(under subclass 300) Process wherein material is removed from a substrate (a) through chemical reaction, (b) by vaporization or decomposition due to the application of a laser, or (c) by mechanically wearing or grinding away a portion of preform to produce a pattern or shape.

(1) Note. Completely dissolving a metal portion of a metal-clad superconducting composite structure or completely dissolving a mask or resist is considered proper for this subclass and its indents.

(2) Note. Mechanically grinding to completely reduce a preform to particulate is excluded from this subclass.
