  • Patent number: 6886442
    Abstract: An apparatus for punching CMP machine backing film. The apparatus comprises a base, a first plate, and a second plate. The base holds the backing-film. The first plate is disposed on the base in a manner such that it moves between a first position and a second position. The first plate abuts the backing-film when it is located at the second position. The second plate, having a plurality of punches, is disposed on the base in a manner such that it moves between a third position and a fourth position. The first plate is located at the first position when the second plate is located at the third position. The first plate is located at the second position when the second plate is located at the fourth position so that the punches pass through the first plate to punch the backing-film.

  • Patent number: 6832422
    Abstract: An apparatus for assembling a post-CMP cleaning brush. The post-CMP cleaning brush is provided with a brush core and an outer brush, and the outer brush is provided with a hollow portion. The apparatus comprises a base, a fixed member, a sliding member, a plurality of posts, and an actuating device. The base holds the brush core and the outer brush, and the fixed member is disposed on the base. The sliding member is disposed on the base in a manner such that it is located at the opposite side of the fixed member relative to the outer brush disposed on the base. The posts, disposed on the sliding member, pass through the fixed member and the hollow portion of the outer brush so as to assist the brush core in passing through the hollow portion of the outer brush. The actuating device connects with the brush core so as to pass the brush core through the hollow portion of the outer brush and separate the posts, inserted into the outer brush, from the outer brush.
