发明名称 CMP PAD DRESSER HAVING LEVELED TIPS AND ASSOCIATED METHODS
摘要 ABSTRACT CMP pad dressers having leveled tips and associated methods are provided. In one aspect, for example, a CMP pad dresser can include a matrix layer and a monolayer of a plurality of superabrasive particles embedded in the matrix layer, where each superabrasive particle in the monolayer protrudes from the matrix layer. The difference in the protrusion distance between the highest protruding tip and the next highest protruding tip of the monolayer of superabrasive particles is less than or equal to about 20 microns, and the difference in protrusion distance between the highest 1% of the protruding tips of the monolayer of superabrasive particles are within about 80 microns or less.
