Specific implementation mode
The utility model is described in further detail with specific implementation mode below in conjunction with the accompanying drawings：
Such as Fig. 3, Fig. 4, a kind of silicon wafer cleaning basket shown in fig. 5, main body is framework, and framework includes side plate 2, bottom support
Structure 4, cross bar 3, for loading silicon chip 1.
Side plate 2 has two pieces, is oppositely arranged.Lower support structure 4 is fixedly installed between two blocks of side plates 2, for propping up silicon
The feather edge of piece 1.Each side plate 2 is provided with hole, and in the frame stability and other functions for not influencing silicon wafer cleaning basket
In the case of, the perforated area on side plate 2 can be arranged more larger as possible, can minimize resistance of the side plate 2 to solution in this way
Gear acts on, to when carrying out alkali cleaning, making herbs into wool and cleaning to silicon chip 1 using the silicon wafer cleaning basket, be convenient for solution clear in silicon chip
The cycle washed inside and outside the gaily decorated basket exchanges so that contact of the silicon chip 1 with solution is more uniform, and then ensures the alkali corruption of silicon chip 1, making herbs into wool more
Add uniform, Wafer Cleaning more clean.
There is detent projection 5, and equidistant parallel is distributed between the protrusion 5 on cross bar 3 on cross bar 3, protrusion 5 is for being isolated silicon
Piece 1.Raised 5 quantity of isolation can be between 0~501, and raised 5 quantity, which increase, can load the quantity of silicon chip 1 and accordingly increase；It is practical
On, in the silicon wafer cleaning basket of the utility model, the specific number of protrusion 5 is not limited, specific number will basis
The demands such as 5 quantity of protrusion needed between 1 quantity of silicon chip loaded and every two adjacent silicon chips 1 are actually needed and set.
Detent projection 5 is diamond shape tooth, round tooth, square shaped teeth, oval tooth or shark tooth, the i.e. cross section of detent projection 5 on cross bar 3
Shape is diamond shape, circle, rectangular, oval or shark tooth form；Certainly, the cross section of protrusion 5 is not limited to above-mentioned shape, former
It is then upper so that protrusion 5 to the greatest extent and the contacts area of silicon chip 1 it is small as possible be preferred.
Preferably, when the cross section of protrusion 5 is rectangular, in cross section, rectangular diagonal line is set perpendicular to silicon chip 1
It sets；Alternatively, when the cross section of protrusion 5 is diamond shape, in cross section, a diagonal line of diamond shape is arranged perpendicular to silicon chip 1.Due to
Using above-mentioned silicon wafer cleaning basket load silicon chip 1 when, silicon chip 1 be inserted into protrusion 5 between, by protrusion 5 cross section in, side
The diagonal line of the diagonal line of shape either diamond shape is arranged perpendicular to silicon chip 1, then the silicon chip 1 being inserted between protrusion 5 only can be with protrusion 5
A seamed edge contact, i.e., silicon chip 1 and protrusion 5 between be only line contact or point contact；Compared to face contact for, line contact and
Point contact can ensure the contact area for having bigger between silicon chip 1 and solution, so that contact of the silicon chip 1 with solution is more equal
It is even abundant, to ensure that the alkali corruption making herbs into wool of silicon chip 1 is more uniform, Wafer Cleaning more clean.
It is equipped with four cross bars 3 between the side of two blocks of side plates 2, is respectively symmetrically fixedly mounted between two blocks of side plates 2, is used for
The lateral edges of silicon chip 1 are limited, and the protrusion 5 on two cross bars 3 for keeping both sides opposite is oppositely arranged；And every is mounted on two pieces of sides
The Inter cross bar 3 of the side of plate 2, protrusion 5 can be formed in vertical direction with 0 °~20 ° angles, i.e. silicon chip 1 after being put into side plate 2
0 °~20 ° angles.
Protrusion 5 can be fixed on cross bar 3, and raised 5 shapes are completely the same, and both sides correspond to the position of the protrusion 5 on cross bar 3
It is completely corresponding；The angle of the homonymy position formation certain angle of the protrusion 5 on two cross bars 3 up and down, when silicon chip 1 is put into and side
2 self-assembling formation of plate, 0 °~20 ° angles.The effect of protrusion 5 is exactly the position of fixed thin slice, is exactly after thin slice is put into referring to Fig. 5
Design sketch, allow thin slice that can keep heeling condition.
An at least cross bar 3, the top sides for limiting silicon chip 1 are detachably installed between the top of two blocks of side plates 2
Edge.The manual operations of dismounting mode, rotation angle or using the material for having certain elasticity stretch fixed mode by being bent dismounting
It is connect with side plate 2.
Using the utility model load silicon chip 1 when, by silicon chip 1 be inserted into protrusion 5 between after, the lateral edges of each silicon chip 1,
Feather edge and top edge are by respectively by cross bar 3, the support limit of lower support structure 4 and top cross bar 3, and per adjacent two
It can be isolated and fix by protrusion 5 between a silicon chip 1；Therefore, each silicon chip 1 can be reliably fixed and silicon chip 1
Between isolation effect it is fine.
Isolation and fixed card slot 105 can only be carried out in compared with the existing technology to the both sides of the edge position of silicon chip 1 (as schemed
Shown in 1) or sawtooth 205 (as shown in Figure 2) structure, protrusion 5 can allow silicon chip 1, heeling condition is formed under self gravitation effect,
This state is fixed by protrusion 5, so as to effectively avoid the adhesion of silicon chip 1, make the alkali corruption making herbs into wool of silicon chip 1 more uniformly,
Wafer Cleaning it is more clean.
Finally it should be noted that listed above is only specific embodiment of the utility model.Obviously, this practicality is new
Type is not limited to above example, can also there is many variations.Those skilled in the art can be from disclosed by the utility model
All deformations for directly exporting or associating in content, are considered as the scope of protection of the utility model.
