Abstract
The utility model relates to a tool in the technical field of semiconductor production, in particular to a crystalline grain selection screen. The crystalline grain selection screen comprises a screen cloth body, a soft protecting layer is arranged on the outside of each of warps and wefts of the screen cloth body, and the soft protecting layer is a plastic layer or a flocking layer. The crystalline grain selection screen has the advantages that the screen can not abrade crystalline grains during usage, and product quality can not be affected.
Description
Technical field
The utility model relates to the apparatus in semiconductor fabrication techniques field, and particularly a kind of crystal grain is selected sieve.
Background technology
Semiconductor grain is the fritter that three telluriumizations, two bismuths are made; qualified product is square structure; need in the production crystal grain is screened; in the prior art; the sieve that uses is common sieve, and the screen cloth of sieve is steel like this, and protective layer is not established on the surface of screen cloth; in the process of screening, can make the crystal grain wearing and tearing, affect product quality.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of and does not affect product quality, can select sieve to the crystal grain that crystal grain screens.
The technical solution of the utility model is achieved in that crystal grain selects sieve, comprises screen body, it is characterized in that: there is the soft protective layer of one deck every warp and the parallel outside of described screen body.
Say that further described soft protective layer is plastic layer or spray suede layer.
The beneficial effects of the utility model are: such crystal grain is selected sieve and is had the advantage that can not wear and tear on crystal grain, not affect product quality when using.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the cross section structure schematic diagram of warp or parallel.
Wherein: 1, screen body 2, warp 3, parallel 4, soft protective layer.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.
As shown in Figure 1, crystal grain is selected sieve, comprises screen body 1, it is characterized in that: there is the soft protective layer 4 of one deck the every warp 2 of described screen body 1 and parallel 3 outsides.
Say that further described soft protective layer 4 is plastic layer or spray suede layer.
Claims (2)
1. crystal grain is selected sieve, comprises screen body, it is characterized in that: there is the soft protective layer of one deck every warp of described screen body and parallel outside.
