摘要:
A tubular product comprises a side section having outer surfaces disposed along a parallelogram and a bottom section formed on one end of the side section. The outer surfaces of the side section are pressure formed by a roller. The tubular product preferably is manufactured from a tubular material by a process comprising the use of a device having a roller that is configured to engage with a side section of the tubular material. The device also comprises a mandrel configured to position the tubular material so that the roller can apply pressure against at least a portion of the outer surfaces of the side section and can extend the side section of the tubular material to form the product.

A polishing device includes a polishing pad for polishing a wafer and a polishing head for holding the wafer. The polishing head has a retainer ring for retaining the wafer in the in-plane direction of the wafer, a membrane sheet for pressing the wafer against the polishing pad, and a head body for supporting the retainer ring and the membrane sheet. The retainer ring has a subordinate retainer member having a ring portion and a plurality of fins extending from the ring portion to retain the peripheral surface of the wafer. The subordinate retainer member has a thickness equal to the thickness of the wafer. The membrane sheet has a diameter larger than the wafer, and presses the wafer and the vicinity of the inner edge of the subordinate retainer member.
摘要:
A dresser adapted to a chemical mechanical polishing apparatus is used to perform dressing on a polishing pad for polishing a semiconductor wafer such that a circular-shaped support surface thereof is positioned opposite to and in contact with the polishing surface of the polishing pad. In the dresser, at least three polish retainers having band-like shapes are formed and elongated in radial directions from substantially the center of the support surface so as to form a plurality of sectorial regions. A plurality of parallel portions are formed in parallel with the polish retainer in each sectorial region. A plurality of band-shaped non-polish retainers are formed between the polish retainer and its parallel portion in each sectorial region. The dresser ensures adequate fuzziness of the polishing pad by way of dressing; hence, it is possible to maintain desired polishing performance of the polishing pad for a long time.
