PROBLEM TO BE SOLVED: To provide a jig for measurement and a wire saw, in which workability is improved and a working efficiency is improved thanks to no need of adjustment each time a workpiece is mounted on a workpiece support section, of the posture of the workpiece relative to the wire saw.SOLUTION: The wire saw includes: a workpiece support section 27 capable of adjusting the position around an axis extending in the vertical direction; and a jig for workpieces detachably attached to the workpiece support section 27 through a plurality of clamp fittings 30 having the positioning function. In place of the jig for workpieces, the jig for measurement 42 is provided to be detachably attached to the workpiece support section 27 through the clamp fittings 30. The jig for measurement 42 is equipped with a camera 44 for detecting the position of a wire 25 between main rollers of the wire saw. The position of the workpiece support section 27 is adjusted based on the position of the wire 25 detected by the camera 44, and the clamp fittings 30 are positioned to predetermined positions relative to the wire 25.

PROBLEM TO BE SOLVED: To provide an apparatus and a method for separating, deflecting and conveying board-shaped substrates (3) such as a solar wafer.SOLUTION: An apparatus (1) for separating, deflecting and conveying the plurality of board-shaped substrates (3), each having a shape of a substrate stack (5), disposed in liquid successively in an aligned manner in a transfer direction, comprises belt conveyors (9) disposed in a vertical direction, including at least two conveyor belts (11, 11''). A conveyance region (10) of the belt conveyors (9) is disposed on a forward side (12) of one end of the stack (5) in parallel to a forward side (12). Each belt conveyor (9) includes a vacuum apparatus (16). A substrate (3) in the top forward position of the stack (5) is capable of being sucked to at least a first conveyor belt (11) by the vacuum apparatus (16). At least the two conveyor belts (11, 11'') of the belt conveyors (9) in the vertical direction are disposed mutually on an identical plane in an adjacent region.

PROBLEM TO BE SOLVED: To provide a semiconductor wafer separation unit for definitely separating sliced wafers one by one and the wafers are not damaged by separation.SOLUTION: The semiconductor wafer separation unit includes a separation tank 1 where a separation liquid containing particles P is circulating. As a result, sludge such as a cooling agent or slicing swarf remaining between sliced wafers are removed from spaces between the wafers and discharged from the bottom of the separation tank 1 as slurry. Additionally, the particles P enter and stay in the spaces between the wafers when the sludge is removed from the spaces between the wafers thereby preventing the wafers from sticking with each other and maintaining a clearance between the wafers constant.

PROBLEM TO BE SOLVED: To provide a processing method of a wafer which can improve processing efficiency and also to provide a processing device used for the processing method of the wafer.SOLUTION: The processing method of the wafer includes a wafer processing step in which an ingot 11 is cut off to form a wafer 31, and a planarization step in which the surface of the wafer 31 is polished and flattened. The planarization step includes a reforming layer forming/polishing step in which the wafer 31 is disposed at a wafer holding part 32, the wafer 31 is processed while being rotated, the heat quantity is applied to a portion to be polished out of the wafer 31 to form a reforming layer 31a, and a polishing tool 33 is abutted on the portion to which the heat quantity is applied out of the wafer 31 to polish while being rotated.
Abstract:
PROBLEM TO BE SOLVED: To scribe small-sized brittle material substrates in good work properties. SOLUTION: On a table 106, a plurality of the brittle material substrates 107a-107i are positioned each by a positioning pin 109 and arranged. A recipe data table is held in advance in each brittle material substrate. The brittle material substrate and a scribe head are moved relatively on the basis of the recipe data table, and an inner cutting scribe or an outer cutting scribe is carries out in each substrate. In this way, scribing work of a plurality of sheets can be carried out all together by automatic operation. COPYRIGHT: (C)2010,JPO&INPIT
