    • PROBLEM TO BE SOLVED: To provide a polishing device capable of carrying out polishing with higher accuracy. SOLUTION: The polishing device carries out polishing of a workpiece W by pressing the workpiece W to a polishing cloth 11 through an elastic sheet body 36 with a pressing force to a carrier 28 by a second pressing means and an inner pressure force of a first fluid chamber 38 by fluid supplied to the first fluid chamber 38. The fluid downwardly supplied into the first fluid chamber 38 flows horizontally outward in the first fluid chamber 38, strikes a side wall 22a of a recess 23 to flow upward, and is discharged outward from each fluid discharge port 44, so that a fluid supply member 31 keeps parallelism with the elastic sheet body 36 by moving to follow the movement of the elastic sheet body 36 and centering is carried out in the first fluid chamber 38.

    • PROBLEM TO BE SOLVED: To provide a double-side grinding apparatus capable of uniformly grinding a wafer and also reducing occurrence of flaws on an outer peripheral part of the wafer to the minimum extent possible. SOLUTION: A coating layer 51 with a predetermined width and a required thickness is formed of a wear-resistant material along a periphery of a through hole 49 on upper and lower surfaces of a carrier body 44a. In addition, a shock-absorbing ring 53 made of resin with the same thickness as that of the carrier body 44a and with a required width is attached to an inner peripheral wall of the through hole 49. The wafer 55 is held in the shock-absorbing ring 53. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供能够均匀研磨晶片的双面研磨装置,并且还可以最小程度地减少晶片的外周部分上的缺陷的发生。 解决方案:具有预定宽度和所需厚度的涂层51由承载体44a的上表面和下表面上的通孔49的周边的耐磨材料形成。 此外,在通孔49的内周壁上安装有由具有与载体主体44a相同的厚度的树脂制成的并具有所需宽度的减震环53。 吸收环53.版权所有(C)2011,JPO&INPIT

    • PROBLEM TO BE SOLVED: To provide a polishing device capable of releasing stress in an elastic material, preventing the elastic material from peeling, eliminating the variation and fluctuation of tensile strength to a backing material, and polishing a workpiece accurately and evenly. SOLUTION: In Fig.3, an elastic thin film 30 is composed of a two-layered film consisting of sheet-like elastic material 42 and a sheet-like backing material 44 bonded to the lower surface of the elastic material 42 and holding the workpiece 24 on a lower surface thereof. The elastic material 42 is formed in a ring-like shape with the center portion hollowed. COPYRIGHT: (C)2011,JPO&INPIT
    • 要解决的问题:提供一种能够释放弹性材料中的应力的抛光装置,防止弹性材料剥离,消除了与背衬材料的拉伸强度的变化和波动,并且准确均匀地研磨工件。 解决方案:在图3中,弹性薄膜30由片状弹性材料42和粘合到弹性材料42的下表面的片状背衬材料44组成的两层薄膜构成, 将工件24保持在其下表面上。 弹性材料42形成为具有中心部分中空的环状形状。 版权所有(C)2011,JPO&INPIT
