Description
Technical field
Manufacture of solar cells technical field is the utility model is related to, more particularly to a kind of graphite boat stuck point for being easy to mark
And graphite boat.
Background technology
At present, among existing solar silicon cell production PECVD, usually used is graphite boat cylinder stuck point,
For blocking the silicon chip among graphite boat piece, to have better energization when carrying out exoelectrical reaction, nitride deposition is set to exist
The surface of silicon chip, form certain thickness silicon nitride film.
In solar cell manufacturing process, when carrying out silicon chip surface plated film, uncoated silicon chip is inserted into PECVD vacuum
On the loader of filming equipment, usual loader is realized by graphite boat, will without plated film silicon chip insert graphite boat, so
Afterwards, the graphite boat for being loaded with silicon chip is placed in PECVD vacuum coating equipment cavitys, silicon chip plated using pecvd process
Film.After plated film terminates, graphite boat is taken out out of vacuum coating equipment cavity, then will pass through the silicon chip of plated film again from graphite boat
Unload and take off.
It will be apparent that on silicon chip plated film be produce solar silicon cell necessary process, and graphite boat as commonly use
Silicon chip carries fixture, can not be substituted under current process conditions.Graphite boat is carried by the stuck point being arranged on graphite boat
Silicon chip to be coated, and traditional cylindrical stuck point, (blocked using the stuck point print on the silicon cell surface after this stuck point plated film
Point print profile) completely all the same (it is just the same that stuck point print is formed i.e. on silicon cell), it is different after the completion of so resulting in PE techniques
Normal silicon cell can not track corresponding graphite boat (because the stuck point print on silicon cell surface is consistent), be not easy to investigation and
Anomaly analysis.
I.e. specifically in the prior art, cylindrical stuck point include cylinder installation portion 1 and along installation portion be in mirror image
Distribution and co-axially fixed stuck point unit；Each stuck point unit include successively the supporting part 2 being fixedly connected with installation portion 1 and
The circular surface portion 3 being fixedly linked with supporting part；In general, stuck point is all to utilize its circular surface portion 3 and the place of supporting part 2
Carrying working face carry silicon cell A.It will be apparent that referring to traditional cylindrical stuck point three-dimensional view (such as Fig. 1) and bow
View (such as Fig. 2), because the edge in circular surface portion 3 has blocked silicon cell A, blocked so causing silicon cell A surfaces
Region shape is completely the same (being semicircular arc, referring to Fig. 3), and then the stuck point impression shape of the silicon cell formed is same
(being the stuck point print of semicircular arc, referring to Fig. 4 and Fig. 5).
Because above-mentioned all silicon cell stuck points are consistent, so result on all silicon cells after the completion of PE techniques
Stuck point print is same, so abnormal silicon cell can not track corresponding graphite boat (because the stuck point on silicon cell surface prints
It is consistent), it is not easy to investigation and anomaly analysis.
To sum up, how to overcome above-mentioned technological deficiency of the prior art is that the technology that those skilled in the art are badly in need of solving is asked
