Patent ID: 7097542

Claim:
A conditioning assembly for polishing a semiconductor wafer, comprising: a base with a first and a second side; a plurality of diamonds on the second side, wherein the diamonds comprise a geometry having between six and eight sides and at least two 90 degree vertices, wherein each of the at least two 90 degree vertices is formed by two edges that meet to form an angle of about 90 degrees; wherein the base has a diameter of between 0.5 and 1.5 inches; wherein the plurality of diamonds includes between 150 and 900 diamonds; wherein the diamonds are embedded within the base; and wherein the second set of vertices of the diamonds having any exterior angles of about 60 degrees or less are embedded in the base; wherein only two of the at least two 90 degree vertices having angles of about 90 degrees protrude from the base and protrude from the base by an approximately equal amount; and wherein all other vertices located on the diamond are positioned below the surface of the base.
