Definitions
- the invention relates to a method for separating wafers from a wafer stack, as they are present in particular after sawing a wafer block and detachment from a beam, for example glass, as well as a device suitable for carrying out this method.
- the stack of wafers is erected after detachment from a beam to which the wafers or the wafer block were fastened, so that the individual wafers are stacked on top of one another. Then the very thin and thus very sensitive wafers are individually removed by hand and placed on a transport path for further transport for subsequent processing.
- the invention has for its object to provide a method mentioned above and a device mentioned above, with the NEN problems of the prior art can be avoided and in particular a fast and very careful separation of goods from a wafer stack is possible.
- the invention it is provided that from the top attacking means of movement on the wafer stack or on the uppermost resting wafer, which are rotating or circumferentially formed and have a suction surface which is directed downward. At this suction surface, the uppermost wafer is applied, wherein the investment of the wafer on the suction surface or thus on the movement means by vacuum or suction can be enhanced.
- the movement means or the suction surface via static friction on the one hand and the negative pressure on the other hand sufficient force can be exerted on the wafer to detach it despite adhesive action on the wafer stack and wegzutransport Schl.
- This adhesion is effected by adhesion due to water on the wafer stack and between the individual wafers, in particular by hydrogen bonds formed there.
- step a) water is pumped from obliquely below the uppermost wafer against its leading edge.
- appropriately designed water nozzles are advantageously provided, at least one, but particularly advantageously two or more. Their effect is that can be separated and fanned out by the water jet, which can even be immersed in water and act there, the leading edges of several adhering wafers.
- step b) the wafers are guided by the moving means via a stripping device, which is designed so that it rests from below on the underside of the moving wafer or the plurality of engaged wafers.
- This stripping device presses the wafer or wafers against the movement means or the suction surface. Further, while the upper surface of the uppermost wafer is moved away from the wafer stack by the moving means, it generates a braking action on the underside of these wafers.
- This scraping device thus also serves to further singulate a plurality of wafers moved away from the wafer stack at one time. If only a single wafer is actually located on the movement means, then the braking action of the stripping device is insufficient to hold it or to detach it from the movement means.
- the stripping device thus serves, similar to the aforementioned irradiation with water, for separating a plurality of gripped wafers. After performing at least one of the two steps described above, the wafer is brought by the movement means on a transport path and then transported on.
- the movement means is first irradiated with water and then or behind the scraper is arranged.
- the moving means may be formed in one embodiment of the invention so that they have a movable circulating belt. It advantageously extends over a greater length, particularly advantageously towards a subsequent transport path, approximately parallel to the upper side of the wafer stack. Then, the aforementioned suction surface is on the movable band or is formed by this, so that when approaching the uppermost wafer to the moving means they rest with the suction surface as fully as possible on the upper side of the uppermost wafer.
- a moving means may be formed radartig or at least have a wheel or a roller.
- a plurality of such wheels or rollers are then arranged one behind the other to form an elongate moving means having a plurality of contact points between the moving means and the wafer top to exert sufficient force on the uppermost wafer so that it can be detached from the wafer stack and transported away.
- At least two similar movement means are provided and arranged side by side or in parallel. They advantageously have a distance from one another or at least two identical movement means are therefore provided, so that said distance or a corresponding gap is provided between them.
- the moving means advantageously have closed surfaces just to form the aforesaid suction surfaces, in the area of said space therebetween a perforated surface is provided which is particularly advantageously rigid and has apertures or holes. At this perforated surface or at the openings a suction effect is generated from above, for example, as a simple suction with a corresponding negative pressure. This will cause the top of the upper - O -
- the perforated surface is advantageously arranged slightly above the suction surfaces, since this perforated surface is advantageously rigid or flat as a plate.
- the movement means could also have openings, for example as a kind of perforated band, and then a negative pressure should be generated from above by suction in order to suck in the upper side of the wafer. In general, it is possible to immerse the wafer stack in water during separation or grasping with the movement means, so that the wafers can be separated more easily.
- the water jet can be aerated to support the separation of the wafer from the wafer stack or contain air or gas bubbles.
- This venting can be generated by introducing air or gas into the water jet or into a nozzle for the water jet.
- This is for example possible in a similar way as the venting of the outlet of a faucet on aeration devices, such as those produced by the company Neoperl in mesh or mesh form.
- Such a ventilated water jet has the advantage that not only the pure water pressure may fan out the leading edges of the uppermost wafer of the wafer stack, but air bubbles can get between individual wafers and thereby the adhesion effect can be canceled.
- a further advantageous effect of this jet of water is that, as described in detail below for the stripping device, it can also serve to press a wafer against the suction surface.
- the water jet has an angle to the horizontal between 20 ° and 70 °. Particularly advantageous, this angle can be between 35 ° and 60 °. - D -
- One possibility for forming a said stripping device may be to attach a type of upwardly directed brush below the transport path of the wafer to the movement means downstream of the wafer stack.
- the brushes should be made of a soft enough material so that the delicate wafers are not damaged or scratched. On the other hand, they should just be able to exert a certain braking effect when one or more wafers are guided past the movement means.
- a certain displacement of the wafers may already have taken place against the transport direction by the water jet.
- the stripping device can reinforce this, so that a separation is simplified.
- a wiping device may be formed revolving or rotating, for example, again as a roll or as a band. It can engage the underside of a wafer or wafers adjacent to the moving means, and decelerate the lowermost wafer or pull it slightly away from the upper ones.
- a transport path for further transport of the wafers is advantageously designed as a roller conveyor. However, it can also bands or the like. exhibit.
- the transport path for depositing and further transport of the wafer behind the stripping device is designed so that it also serves for further separation of still at least partially superimposed wafers. For this purpose, it may have several sections, which lie one behind the other in the transport direction and each have an increasing speed.
- step a) or b) a group of, for example, three or four wafers, which still partially adhere to one another, is displaced by the upstream water jet nozzle and the stripping device so that the uppermost wafer with its front canopy te protrudes a good distance over the lower wafer, this is first taken from the respective following section of the transport path. If this section is faster than the previous one and if there is a speed difference, then it is additionally pulled away from the other wafers, either completely or at least a little further. By providing a plurality of such sections, each of which increasingly has a faster speed, a secure separation of several wafers ultimately takes place. For this purpose, it is also advantageous if the surface or upper side of the transport path is formed strongly adhering in conjunction with the undersides of the wafer.
- a further improvement in the removal of individual wafers from the wafer stack can be achieved by moving the wafer stack up and down in a manner of oscillating movement or evenly. This can be done with a repeat time of a few seconds, for example three to five seconds. A rash or amplitude should be a maximum of 10mm, preferably about 5mm. If a time similar to the aforesaid repetition time in the range of a few seconds is selected as the cycle time for the removal of a wafer from the wafer stack, then it can be set that each time the wafer stack reaches its vertex, the uppermost wafer strikes against the moving means or the suction surface is pressed, which then does not have to move down. The gripping action or adhesion should occur very quickly because of continuous suction.
- FIG. 1 is a side view of a schematic functional structure of a device according to the invention for explaining the method according to the invention
- Fig. 2 is a plan view of moving means in the form of two parallel belts with a broken surface in between and
- FIG. 3 shows a modification of the moving means of FIG. 2 with a single band with perforated surface. - y -
- FIG. 1 shows a device 11 according to the invention, with which individual wafers 12 are removed from a wafer stack 16 and transported away for further transport for further processing.
- the wafers 12 are shown with their upwardly facing top 14 and a left leading edge 13. They are stacked on the wafer stack 16 which is located on or in a cassette 17. This in turn is attached to or in a lifting device 18.
- the cassette 17 with the wafer stack 16 is introduced by means not shown in the lifting device 18, which in turn is arranged in a water tank 21 filled with water 20. It can be seen that the upper side 14 of the uppermost wafer 12 of the wafer stack 16 is approximately at the level of the edges of the water tank 20 or slightly below.
- the water tank 20 may have a certain overflow, which ensures that, for example, by refilling the water 21 from below, the individual wafer 12 and the wafer stack 16 floats or is fanned slightly upwards and a certain water circulation is ensured.
- DI water or cleaning solution may be included.
- the dashed arrow next to the lifting device 18 illustrates that it moves up and down with the aforementioned movement, for example at a distance or with a movement time of a few seconds and a maximum movement height of 10 mm.
- moving means 23 which have a circulating in a clockwise direction band 24 or two of them next to each other.
- a surface 25 of the belt 24 forms the aforementioned suction surface 25.
- a suction device 27 By means of a suction device 27, a negative pressure is applied such that the upper side 14 of the uppermost wafer 12 of the wafer carrier Pelt 16 is pressed against the belt 24 or its suction surface 25 and is then detected by the latter and is moved to the left away from the wafer stack 16.
- a water nozzle 29 is shown whose jet direction is directed at an angle of approximately 45 ° to the horizontal against the leading edge 13 of the uppermost wafer 12 on the wafer stack 16.
- a water jet 30 generated by this water nozzle 29 can be aerated by aeration means (not shown). Even if the water jet 30 is generated, so to speak, in the midst of the water 21 of the water tank 20, nevertheless a beam effect can be achieved, which is ready for fanning the leading edges or the wafer 12 serves at the top of the wafer stack 16, in particular the detachment of if possible only one wafer 12 or as less wafer 12 from the wafer stack 16 by means of the movement means 23 to effect.
- the movement means 23 guide the one or more wafers 12 via an aforementioned stripping device, which is designed as a brush 32. It advantageously extends over the entire width of a wafer 12 or of the wafer stack 16 and has upwardly directed bristles, which may possibly also be directed somewhat against the transport direction of the wafer 12.
- the underside 15 of a wafer 12, which together with other wafers 12 has been released as a small stack from the wafer stack 16 by the movement means 23, abuts against the brush, it brakes it in relation to the other wafers or at least in relation to top wafer 12, which rests directly on the suction surface 25.
- a plurality of still adhering wafers 12 can be singulated or at least shifted relative to one another such that their leading edges 13 have a certain distance, for example several Centimeters, to each other.
- the suction of the suction device 27 or further, not shown here, suction devices is also provided above the brush 32. It can thereby be achieved that, so to speak, wafers 12 braked or detached from the brush 32 by the movement means 23 are subsequently gripped again by the suction surface 25 and are transported further to the left.
- the movement means 23 lead beyond the brush 32.
- a first conveyor belt 35 is provided and thereafter a second conveyor belt 37, etc.
- the first conveyor belt 35 has some distance both to the moving means 23 and to the brush 32. It is obvious that at least after the brush 32, in the case where a plurality of wafers 12 adhere to the suction surface 25, their leading edges 13 are shifted to the right. This means that first of all the wafer 12 adhering directly to the suction surface 25 reaches the first conveyor belt 35 or rests on it.
- This first conveyor belt 35 runs at a significantly higher speed than the moving means 23, for example, twice the speed.
- the remaining wafers are still braked by the brush 32. This also causes the uppermost wafer 12 to be pulled away as a single wafer and then rests individually on the first conveyor belt 35.
- the second conveyor belt 37 following directly behind the first conveyor belt 35 again runs at a considerably higher speed, for example at least twice the speed.
- the effect due to the speed difference is similar to that of the brush 32, namely, the speed difference serves to grip the leftmost wafer 12 first as well and from other wafers, which rest with their bottom 15 still on the first conveyor belt 35, pull away.
- the wafers 12 typically have a thickness of just over 200 ⁇ m and edge lengths of between 100 and 200 mm in a rectangular or approximately square format.
- FIG. 2 is a Thomasaufsicht on a median plane of a section through the movement means 23 shown in FIG. 1.
- the moving means 23 comprise two similar belts 24a and 24b, which run side by side at a certain distance, which is smaller than their width, and are driven by wheels 26a and 26b.
- the outer surfaces or surfaces of the bands 24a and 24b form the above-described suction surface 25. This is not necessarily to mean that this surface 25 suck itself, but that the tops 14 of the wafer 12 are applied by suction against it.
- a perforated plate 39 Over the gap between the bands 24a and 24b extends a perforated plate 39 with a plurality of small holes 40, for example, with a diameter of a few millimeters.
- three intake devices 27 Above the perforated plate 39 are three intake devices 27, for example in the manner of pipes. These suck with negative pressure, namely water 21 from the water tank 20. At the same time suck it but also through the holes 40, the top 14 of the uppermost wafer 12 from the wafer stack 16 at. This thus moves upwards or remains attached to the suction surfaces 25 of the bands 24a and 24b, while still being pulled up by the suction. Since the wafer 12 but should not be present at the perforated plate 39 directly, but - IO ⁇
- the wafer 12 is shown here in dashed lines in a position as it is located on the wafer stack 16.
- more than two bands 24 could be provided side by side and then a plurality of perforated plates 39 in between.
- the bands 24 could also, as previously mentioned, be provided wheels.
- ribbons are clearly preferred.
- FIG. 3 A modification of movement means is shown in FIG. 3 with movement means 123, which have a single band 124.
- This band 124 runs on two wheels 126, similar to the bands in Fig. 2. Since no distance between the bands is provided and thus no perforated plate can be used as shown in Fig. 2, the band 124 is itself formed open or broken Holes 140, for example, similar to those of the perforated plate 39 of FIG. 2.
- suction device 27 can be continued in tube form in FIG. 2 directly upwards, they must be led away in Fig. 3 to the side, quasi out of the circumferential loop of the belt 124 out.
