Embodiment
Below in conjunction with the accompanying drawing in the present invention, the technical scheme in the present invention is clearly and completely described.
The method of nozzle movement in a kind of Wafer cleaning process is embodiments, provides of the present invention first.The method comprises the following steps:
Detect the rotating speed RPM of disk.As shown in Figure 1, disk is positioned on disk plummer, and disk plummer rotates and drives disk synchronous axial system.
Detect effective cleaning width x of nozzle spray.In another embodiment, the sequencing of above-mentioned two steps can be replaced.That is, effective cleaning width x of nozzle spray is first detected; Then the rotating speed RPM of disk is detected, i.e. (60 seconds) number of revolutions per minute.
Preferably, before the effective cleaning width x step detecting nozzle spray, also comprise adjustment nozzle spray drop point, make water spray drop point fall within wafer pivot to improve cleaning quality.
According to the rotating speed of disk and effective cleaning width x moving nozzle of nozzle spray.As shown in Figure 2, if r is the radius of disk, l is the length across full wafer disk, is equivalent to 2r, then arm of spraying water completes a range, and to move required number of times be l/x, or 2r/x.It is 60/RPM (unit: second) that disk revolves the required time that turns around.
In order to improve the cleaning efficiency of cleaning machine, disk revolves Integratively cleaning of having turned around, and the time required is like this shortest, i.e. l/x=1, or 2r/x=1.Therefore, in Wafer cleaning process provided by the invention, nozzle moves in moving method, and the required cleaning shortest time is t=l/x60/RPM.Therefore, in implementation process, arm of can spraying water when the moving range of arm of spraying water covers full wafer disk completes and once moves, and each region of disk can be cleaned once.Then disk rotating speed with the pass of water spray arm translational speed is:
v＝l/t·2＝2r/t·2＝2r·RPM/60·x/2r·2＝[RPM·x/60]·2
Above-mentioned v is the translational speed of water spray arm, and the namely translational speed of nozzle, unit is mm/second.V=l/t2, take advantage of 2 to be because l is length across full wafer disk, be equivalent to 2r, namely often circle has cleaned 2 times, take advantage of 2 be equivalent to speed doublings then wash number reduce by half.
In an illustrative embodiment, suppose that disk rotating speed is 300RPM, water spray effective width is 0.01inch (0.254mm), then
v＝[RPM·x/60]·2＝[300·0.254/60]·2＝1.27·2＝2.54mm/sec
That is, for when arm translational speed of spraying water is more than 2.54mm/sec, just may there is blind area in Wafer cleaning; Although during Wafer cleaning, water spray arm can not only have swing once, but can swing a period of time back and forth, and water spray arm translational speed is too fast or can reduce the effect of cleaning, and subregion is not yet cleaned to; On the other hand, arm translational speed of spraying water crosses the production capacity and efficiency that can reduce machine slowly.
Because disk moves and moves with arm of spraying water is relative, the effect that disk does not move water spray arm movement moves with disk and the effect of arm not movement of spraying water is the same.Therefore, the method for disk movement in a kind of Wafer cleaning process is embodiments, provides of the present invention second.The method comprises the following steps:
Step one: the rotating speed RPM detecting disk, i.e. (60 seconds) number of revolutions per minute.
Step 2: the effective cleaning width x detecting nozzle spray.It will be understood by those of skill in the art that the sequencing of above-mentioned two steps can be replaced.That is, effective cleaning width x of nozzle spray is first detected; Then the rotating speed RPM of disk is detected.
Step 3: according to the rotating speed of disk and effective cleaning width x removable wafer of nozzle spray.As shown in Figure 2, if r is the radius of disk, l is the length across full wafer disk, is equivalent to 2r, then arm of spraying water completes a range, and to move required number of times be l/x, or 2r/x.In Wafer cleaning process provided by the invention, disk moves in moving method, and the required cleaning shortest time is t=l/x60/RPM.Therefore, in implementation process, can complete and once move by disk when the moving range of arm of spraying water covers full wafer disk, each region of disk can be cleaned once.Then disk rotating speed with the pass of water spray arm translational speed is:
v＝l/t·2＝2r/t·2＝2r·RPM/60·x/2r·2＝[RPM·x/60]·2
Above-mentioned v is the translational speed of disk, and unit is mm/second.V=l/t2, take advantage of 2 to be because l is length across full wafer disk, be equivalent to 2r, namely often circle has cleaned 2 times, take advantage of 2 be equivalent to speed doublings then wash number reduce by half.
In an illustrative embodiment, suppose that disk rotating speed is 300RPM, water spray effective width is 0.01inch (0.254mm), then
v＝[RPM·x/60]·2＝[300·0.254/60]·2＝1.27·2＝2.54mm/sec
That is, for when disk translational speed is more than 2.54mm/sec, just may there is blind area in Wafer cleaning; Maintenance water spray arm is motionless and disk moves, and can reduce the effect of cleaning when disk translational speed is too fast, subregion is not yet cleaned to, and disk translational speed crosses the production capacity and efficiency that can reduce machine slowly.
