- FIG. 2A and 2B are diagrams showing the configuration of a wafer jig of the present invention.
- FIG. 2A is a plan view
- FIG. 2B is a cross-sectional view taken along a line A of FIG. 2A.
- FIGS. 3A to 3D are diagrams showing a configuration of a gripping mechanism of a wafer jig of the present invention, wherein FIG. 3A is a plan view, FIG. 3B is a side view, and FIG. 3C is a rear view. 3D is a cross-sectional view taken along the line AA.
- FIG. 4A and 4B are diagrams showing the configuration of the energizing pins and the seal packing of the wafer jig of the present invention.
- FIG. 4A is a plan view
- FIG. 4B is a cross-sectional view taken along line CC.
- FIG. 5A and FIG. 5B are views for explaining a procedure for mounting a wafer on the stick jig of the present invention.
- FIG. 6A and 6B are diagrams showing the configuration of a wafer jig of the present invention, wherein FIG. 6A is a plan view and FIG. 6B is a side view.
- FIG. 2 is a diagram showing the configuration of a wafer jig.
- FIG. 2A is a plan view, and FIG.
- this mounting jig 10 is provided with a circular opening 12 at the center position of the plate-shaped jig main body 11, and a plurality of openings 12 are provided around the opening 12 (in the figure, (8 pieces) of wafers.
- FIG. 3 is a diagram showing the configuration of the gripping mechanism 13, FIG. 3A is a plan view, FIG. 3B is a side view, FIG. 3C is a rear view, and FIG. 3D is a sectional view taken along the line AA.
- the gripping mechanism 13 includes a pedestal 14, a hinge pin 15, a holder 16, and a coil spring 17, and the holder 16 is provided with both ends 14 a, 14 a of the pedestal 14 by the hinge pin 15.
- the tip 16a is urged by the coil panel 17 in the direction of the lower end surface of the pedestal 14 on the jig body side (see the arrow B in FIG. 3B).
- the pedestal 14 is fixed to the jig body 11 with screws 18 and 18.
- a resin cylinder 19 is interposed between the coil spring 17 and the hinge pin 15 as shown in FIG. 3D.
- the energizing pin 21 covered with the seal packing 20 is provided at the position where the tip 16 a of the holder 16 of the pedestal 14 opposes as shown in FIG. 4 c.
- Numeral 20 is made of, for example, silicon rubber or fluorine rubber, and is formed by molding around the enlarged diameter portion 21 a of the current supply pin 21.
- FIG. 4 A is a plan view
- the Figure 4 B Press rear portion 1 6 b and c gripping mechanism 1 3 of the holder 1 6 is a C-C cross-sectional view
- a holder 1 6 co Irubane 1 7 bullets It is piled on the spring force and pivots around the hinge pin 15 to open, and when released, the spring panel 17 pivots in the opposite direction to the hinge pin 15 and closes.
- the wafer W is sandwiched between the end of the energizing pin 21 and the end 16a of the holder 16 (see FIG. 3B).
- the seal packing 20 has a cylindrical shape and its tip comes into contact with the surface of the wafer W while being in contact with the conductive film formed on the W. Thus, the energizing pin 21 is completely sealed from the plating liquid by the seal packing 20. In particular, since the end of the seal packing 20 is formed in a trumpet shape, the end of the seal packing 20 comes into close contact with the surface of the wafer W and exerts its sealing action.
- a plurality of gripping mechanisms 13 simultaneously press the rear ends 16 b of the holders 16 of the wafer mounting jig, and a rectangular gripping mechanism.
- the wafer W is moved to the vicinity of the tips of the plurality of energizing pins 21 with a predetermined jig 23, and the jig 22 is lowered in this state. Is automatically positioned. That is, the surface of the holder 16 facing the edge of the wafer W is shaped so as to press the wafer W toward the center of the opening 12 by rotating about the hinge pin 15.
- FIG. 5 A when this c is a B- B cross section of FIG. 2 A, the seal packing 2 0 as described above in cylindrical shape which is by Uni molded surround the energizing pins 2 1, moreover the tip thereof Are formed in the shape of a flute, so that when they come into contact with the surface of the wafer W, the sealing area is small and the sealing surface pressure is high even if the pressing force is small, so that each of the energizing pins 21 is completely sealed.
- the opening 12 is not limited to a circular shape.
- the shape may be rectangular, for example, as shown in FIGS. 6A and 6B according to the shape of C, and a plurality of gripping mechanisms 13 may be disposed around the rectangular shape.
- various electronic components for energizing the wafer W through the energizing pins 21 are mounted on the plating jig 10, for example, at a portion D in FIG. 2, but the description is not directly related to the present invention. Omitted.
- a seal packing is provided so as to surround the periphery of each energizing pin, and each energizing pin is sealed by the seal packing when the wafer is gripped by the gripping mechanism. since it is configured, small sealing surface, because the sealing surface pressure with low pressure pressing is high, sealing performance is improved c
- the seal packing is formed by molding on the energizing pin, and the end thereof has a frusto-conical shape and has a predetermined dimension from the end of the energizing pin.
- the positional relationship of the tip of the seal packing is constant, and the stability of the seal is good.
- the wafer since the wafer is configured to be automatically positioned by opening and closing the gripping mechanism, a plurality of gripping mechanisms are simultaneously opened and closed, so that the wafer and the wafer are simultaneously positioned. availability on c industrial positioning of the mounting portion of the main luck jig is facilitated
- the present invention is useful for use in an apparatus that applies plating to a semiconductor wafer or the like.
