The fixed abrasive grain processed device and fixed abrasive grain process manner, and the fixed abrasive grain processed device which

摘要

Disclosure relates to a fixed abrasive-grain processing device and a method of fixed abrasive-grain processing used for producing a semiconductor wafer, and a method for producing a semiconductor wafer which make the surface of the semiconductor wafer possible to have preferable flatness and which can prevent the number of steps and the installation area of facilities from increasing. The producing of semiconductor wafers (W) uses a fixed abrasive-grain processing device (1) including a lower fixed abrasive-grain layer (21) that is adjacent to the top surface of the lower surface-plate (2) and that grinds the top surfaces of the plurality of semiconductor wafers (W); an upper fixed abrasive-grain layer (31) that is adjacent to the bottom surface of the upper surface-plate (3) and that grinds the bottom surfaces of the plurality of semiconductor wafers (W); a carrier plate (4) that is horizontally interposed between the lower surface-plate (2) and the upper surface-plate (3) and that includes a plurality of holes (4a) each accommodating one of the plurality of semiconductor wafers (W); and a carrier rotating device (40) that circularly moves the carrier plate (4), wherein the lower fixed abrasive-grain layer (21) and the upper fixed abrasive-grain layer (31) include fixed abrasive grain (21b, 31b) having a diameter of 4 µm or less and being dispersed and fixed in elastic members (21a, 31a).
