- the present invention relates to a novel wafer isolation device that can safely, easily and reliably separate a wafer from an adjacent lower wafer.
- semiconductor wafers hereinafter simply referred to as “wafers”
- wafers such as thin silicon wafers sliced and cut out from a silicon ingot or the like are then subjected to various kinds of processing to become final products.
- a large number or a plurality of wafers are stacked to form a wafer stack (commonly referred to as a coin stack), and the wafers are separated one by one from the wafer stack. It is usually processed for each wafer.
- liquid such as oil adheres to the wafer surface after various treatments, for example, as if abrasive containing slurry (slurry) remains on the surface of the wafer sliced from the ingot. Often. When a large number or a plurality of wafers are stacked, the surface tension of these liquids existing on the wafer surface allows the wafers to move to the side, but to move upward from the adjacent lower wafer. It is difficult to pull apart.
- the present inventor has proposed a wafer in which a large number or a plurality of wafers are stacked.
- the edge of the uppermost wafer of the stack is warped upward, fluid is blown between the lower surface of the uppermost wafer and the upper surface of the adjacent lower wafer, and the uppermost wafer is raised.
- We have proposed a wafer isolation device that isolates a wafer see Japanese Patent Application Laid-Open No. Hei 9-164152).
- the central part of the uppermost wafer W1 of the wafer laminate WS in which a plurality of wafers or a plurality of wafers are laminated is a wafer pressing means 2
- the peripheral portion of the wafer W1 is attracted by the wafer suction means 22a and 22b to warp the peripheral portion of the wafer W1 upward, and adjacent to the lower surface of the uppermost wafer W1
- Fluid F water and / or air
- the fluid ejecting means 24a and 24b is blown into the gap D between the upper surface of the lower wafer W2 and the upper surface wafer W1 by the fluid ejecting means 24a and 24b.
- W1 is isolated from the wafer stack WS.
- wafers could be easily and reliably separated one by one from the wafer stack.However, an accident that the wafer was broken at the portion indicated by the symbol A in Fig. 6 could occur. was there.
- the center of the disk-shaped wafer Wa is pressed by the wafer holding means 20 while passing through the center of the wafer.
- the two peripheral points of the opposing wafer are vacuum-sucked by the wafer suction means 22a and 22b so that the peripheral edge of the wafer Wa is warped upward.
- a bending stress is generated at a portion along a line segment perpendicular to the line segment (the line segment indicated by the symbol A-A 'in Fig. 7 (a)). Since a semiconductor wafer such as a silicon wafer is a brittle material, it is very brittle to such a bending stress, and may be broken at a portion where the bending stress occurs.
- Fig. 7 (b) in the case of a solar cell manufacturing wafer Wb, whose production has been increasing in recent years, the wafer itself is processed into a substantially square shape, so that the wafer By vacuum-adsorbing the two points on the periphery in the opposite direction to warp the wafer periphery upward, it is even more difficult than in the case of a general disk-shaped wafer Wa (see Fig. 7 (a)). It is brittle against bending stress, and is very susceptible to cracking along the line indicated by A-A 'in Fig. 7 (b).
- An object of the present invention is to provide a wafer isolation apparatus capable of safely, easily and surely isolating a wafer, and improving a processing speed for isolating a wafer.

At least two pairs facing each other While the upper edge of the wafer is warped upward at two or more pairs of suction positions, and the fluid is interposed between the lower surface of the uppermost wafer and the upper surface of the adjacent lower wafer. A fluid is blown by the jetting means, and the wafer of the uppermost layer is raised to isolate the wafer.

They must be in a relationship, preferably in a positional relationship of intersecting at an angle of 70 to 110 degrees, most preferably in a perpendicular or substantially orthogonal position relationship.

- Liquids such as slurry at the time of slicing remain adhered to a thin-layered silicon wafer or the like sliced and cut from a silicon ingot or the like. Since it is in a semi-dry state, it becomes extremely unstable due to failure of suction by wafer suction means or incomplete suction. Thus, as described above, if the suction position is washed by ejecting the liquid from the vacuum suction nozzle, problems such as suction failure and incomplete suction can be eliminated.
- the wafer suction means is a vacuum suction nozzle having a liquid jetting function, and that a pipe connected to the vacuum suction nozzle is cleaned by jetting a liquid from the vacuum suction nozzle.
- the wafer The remaining liquid such as slurry at the time of the chair is adhering.
