Embodiment
For above and other objects of the present invention, feature and advantage can be become apparent, a preferred embodiment cited below particularly, and conjunction with figs. are described in detail below:
Please refer to Fig. 2, is a profile, shows the wafer feeding device of first embodiment of the invention and the first step of wafer pan feeding method.
Wafer feeding device of the present invention is applicable to long length of side L, the long W of minor face and L〉wafer 10 of W, comprise a bed die 110 and a mold 120.
Bed die 110 has first nib 113 of a plurality of spaced funnel types, and each first nib 113 has width R respectively 11A upper shed 111 and width R 12A under shed 112, and R 11L〉R 12W.
120 of molds place on the bed die 110, have a plurality of second nibs 122 corresponding to each first nib 113, and respectively this second nib 122 has width R respectively 2Opening, and R 2L.In Fig. 1, first nib 113 does not overlap mutually with second fenestra 122; And in the subsequent step of wafer pan feeding method of the present invention, first nib 113 and second nib 122 are overlapped.
Wafer feeding device of the present invention optionally more comprises a bottom die 130, places bed die 110 times.Bottom die 130 has a plurality of the 3rd nibs 132 corresponding to first nib 113, and each the 3rd nib 132 has width R respectively 3Opening, and L R 3W.At this moment, the 3rd nib 132 is preferably with corresponding first nib 113 and overlaps.
As shown in Figure 2, in the wafer pan feeding method of first embodiment of the invention, at first wafer 10 is placed on the mold 120 of wafer feeding device of the present invention, shake wafer feeding device of the present invention then, be preferably vibrations in horizontal direction, make wafer 10 enter second nib 122 to grow the downward mode in limit.
Please refer to Fig. 3 then, remove wafer unnecessary on the mold 120 10, that is be the wafer 10 that does not enter second nib 122, for example can make the wafer feeding device of the present invention set angle that tilts, and remove the wafer that does not enter second nib 122 10 shown in Figure 2 by gravity.
Next, please refer to Fig. 4, make mold 120 and bed die 110 produce relative motion, A direction or its rightabout in the figure for example, first nib 113 and second nib 122 are overlapped, and make the wafer 10 in second nib 122 downward-sloping respectively, and enter the first corresponding nib 113 in the downward mode of minor face by gravity.
Next, please refer to Fig. 5, enter in the process of first nib 113 by second nib 122, can shake wafer feeding device of the present invention at wafer 10, the for example direction of the two arrow B in figure vibrations are so that wafer 10 enters the process of first nib 113 is more smooth and easy.In addition, when wafer feeding device of the present invention optionally disposed bottom die 130, its 3rd nib 132 coincided with the first corresponding nib 113 at this moment, and made the wafer 10 that enters first nib 113 in the downward mode of minor face be contained in the 3rd nib 132.At this moment, bottom die 130 can be unloaded from wafer feeding device of the present invention, the bottom die 130 that takes up wafer 10 is removed and carried out the step that follow-up step for example forms external electrode, and make wafer feeding device of the present invention be carried out the operation of next echelon immediately.
As mentioned above, by wafer feeding device of the present invention and wafer pan feeding method, can be that minor face is downward successfully with wafer 10 correctings, reach the purpose of the invention described above.
In first embodiment, when making wafer 10 enter second nib 122 to grow the downward mode in limit, if the direction that enters, when angle is not controlled, wafer 10 might not enter second nib 122 fully, and reduces the filling rate of second nib 122.Therefore, for the filling rate and then the lifting production capacity of better lifting wafer feeding device of the present invention, the wafer feeding device of following second embodiment of the invention is improved at mold 120.
Please refer to Fig. 6, is a profile, shows the wafer feeding device of second embodiment of the invention and the first step of wafer pan feeding method.
The wafer feeding device of second embodiment of the invention is applicable to long length of side L, the long W of minor face and L〉wafer 30 of W, it comprises a tabular mould 300, has a nib 310 through wherein, and nib 310 has width R uA upper shed 301, with width R bA under shed 302, satisfy R bL〉R uW, and nib 310 more comprises the first side wall and second sidewall.
Above-mentioned the first side wall has first limit 311 and 312, the first limits 311, second limit are downward-sloping from upper shed 301, accompanies a set angle with horizontal plane, is preferably to be less than or equal to 45; And second limit 312 extends upward under shed 302, intersects with first limit 311 and forms a salient angle 310a.
The second above-mentioned sidewall is then relative with above-mentioned the first side wall, have the 3rd limit 313, the 4th limit 314, with the 5th limit 315, the 3rd limit 313 is downward-sloping from upper shed 301, be in substantially parallel relationship to first limit 311, the 5th limit 315 extends upward under shed 302, and 314 on the 4th limit connects the 3rd limit 313 and the 5th limit 315, and forms a block 310b with the 5th limit 315, the air line distance of block 310b and salient angle 310a is X, and satisfies X 2〉=L 2+ W 2
The vertical view of the wafer feeding device of second embodiment of the invention is illustrated in Fig. 9.The upper shed 301 of nib 310 has the downward lead angle 301a in inclined-plane, can help wafer shown in Figure 6 30 to enter nib 310 by all directions.
Refer again to Fig. 6, wafer 30 enters after the nib 310, because the width of upper shed 301 is between the length on the long and short limit of wafer 30, so wafer 30 enters nib 310 with minor face, and its long edge first limit 311 and slides.
Next please refer to Fig. 7, the part of wafer 30 can touch link stopper 310b.And please refer to Fig. 8, and wafer 30 is because of being subjected to stopping of blocks of files 310b, and the part that it contacts with link stopper 310b just becomes a fulcrum; And because the air line distance of block 310b and salient angle 310a is X, and satisfy X 2〉=L 2+ W 2That is the air line distance of block 310b and salient angle 310a is more than or equal to the catercorner length of wafer 30, act on wafer 30 gravity this moment and can guarantee that by above-mentioned fulcrum makes wafer 30 rotations wafer 30 falls in the nib 310 to grow the downward mode in limit, promote the filling rate of wafer 30.
Though the present invention discloses as above with preferred embodiment; right its is not in order to qualification the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little change and retouching, so protection scope of the present invention is with being as the criterion that claims were defined.
