Daughter 30 is etched and is damaged, and is conducive to improve the service life of support arm 132.Certainly, in some embodiments, support arm 132
Material can be not limited to embodiments discussed above, and can be made as needed of suitable etch-resistant material.
It is appreciated that support arm 132 step structure 1322 limit workpiece 20 displacement and be unfavorable for travelling workpiece 20 with
Workpiece 20 is made to pass in and out etch chamber 11.Second support device 14 can before the etch or etching is completed rear support workpiece 20 and risen,
Support arm 132 declines so that workpiece 20 moves at this time.During etching, workpiece 20 may the influence generation temperature change of subject plasma 30
Change and cause 20 softening transform of workpiece, therefore, support arm 132 rises in etching process and the second support device 14 declines, and avoids
Second support device 14 be in direct contact workpiece 20 so that 20 back side out-of-flatness of workpiece and influence 20 yield of workpiece.
In some embodiments, the second support device 14 includes spaced multiple support columns 142.Support column 142
Penetrating electrode plate 12 simultaneously is configured to that workpiece 20 is supported to lift.
It, can before the etch or rear support work is completed in etching in this way, support column 142 is arranged between two support arms 132
Part 20 rises.It is appreciated that support column 142 supports one end of workpiece 20 to be located at same supporting plane, workpiece 20 can be placed on
It is lifted on supporting plane.In addition, support column 142 can be uniformly arranged, be conducive to steadily support workpiece 20 in this way.
Specifically, in some embodiments, multiple support columns 142 are in array distribution.In this way, the support column of array distribution
142 on same line the distance of two neighboring support column 142 it is equal so that the support force that workpiece 20 is subject to is uniformly distributed, together
Sample is conducive to steadily support workpiece 20.Certainly, in some embodiments, the distribution mode of support column 142 can also be according to work
The size and shape of part 20 is configured.
In some embodiments, the quantity of support column 142 can be according to the shape, size and weight and support of workpiece 20
Enabling capabilities of column 142 etc. are converted.
Also referring to Fig. 2, Fig. 3 and Fig. 4, in some embodiments, support arm 132 includes being arranged on step structure
Shock absorber part 1326 on 1322.
In this way, support arm 132 is used to support workpiece 20, the higher material of generally use hardness is made, and workpiece 20 is directly put
It puts and is easily damaged on support arm 132.Shock absorber part 1326 is provided on step structure 1322 can cause support arm 132
Cushioning effect can be played during stress during support workpiece 20, workpiece 20 is reduced or avoided and damages.
In some embodiments, the first support device 13 is formed through support arm 132 and connects support slot 1324
Venthole 1328.
In this way, during etching, workpiece 20 may subject plasma 30 influence to generate temperature change, etching machines 10 can lead to
It crosses venthole 1328 and conveys cooling gas to workpiece 20 so that the part that workpiece 20 is placed on step structure 1322 can be by cold
But the influence of gas and keep lower temperature, be conducive to keep 20 stable structure of workpiece and being etched.
In the illustrated embodiment, 1328 vertical connection support slot 1324 of venthole.Shock absorber part 1326 can be rubber pad.
In this way, shock absorber part 1326 is usually the highly elastic material with reversible deformation, such as rubber pad can protect workpiece 20
It is not easy to be supported 132 active force of arm in etching process and damage.
In some embodiments, shock absorber part 1326 and venthole 1328 are arranged at intervals.
In this way, shock absorber part 1326 and the interval of venthole 1328 enable venthole 1328 to convey cooling gas to workpiece 20
So as to keep lower temperature.
Specifically, in some embodiments, shock absorber part 1326 is 3, venthole 1328 is 2.Shock absorber part 1326 and logical
Stomata 1328 is arranged alternately.Certainly, in other embodiments, the quantity of shock absorber part 1326 and the quantity of venthole 1328 can roots
It is converted according to the size of the size of support arm 132, the size of shock absorber part 1326 and venthole 1328.
In some embodiments, shock absorber part 1326 can be in cone.In this way, workpiece 20 contacts the vertex of cone, erosion is reduced
The contact area of shock absorber part 1326 and workpiece 20 during quarter, meanwhile, increase cooling gas and the contact area of workpiece 20, be conducive to lose
Carve workpiece 20.
