Abstract
The utility model relates to the technical field of semiconductor production, in particular to an auxiliary material which is low in value and easy to consume. The auxiliary material is a crystal pulling tube easy to fix. The crystal pulling tube easy to fix comprises a crystal pulling tube body. The crystal pulling tube body is made of glass and of a tubular structure with one closed end and one opened end. The crystal pulling tube easy to fix is characterized in that positioning structures which are concave in the middle are arranged outside the crystal pulling tube body. The positioning device is of a concave annular structure or the two positioning structures are of plane structures which are arranged on the two sides of the crystal pulling tube body. The two positioning structures are arranged on the crystal pulling tube body and adjacent to the two ends of the crystal pulling tube body. The crystal pulling tube has the advantages of being capable of ensuring normal production, easy to position and strong when placed in a crystal pulling furnace.
Description
Technical field
The utility model relates to the semiconductor fabrication techniques field, relates to a kind of low value easily subsidiary material, particularly a kind of crystal pulling tube of consumption.
Background technology
During use, raw material is put into to crystal pulling tube, and crystal pulling tube is placed in crystal pulling furnace and processes, in prior art, the crystal pulling tube periphery does not have locating device, rely on the furnace chamber restriction crystal pulling tube of crystal pulling furnace,, add the man-hour crystal pulling furnace and ceaselessly swing, do not have the crystal pulling tube of location to tend to occur the phenomenon misplaced, crystal pulling tube easily breaks, and impact is normally produced, and also can waste raw material.
Summary of the invention
The purpose of this utility model is exactly for above-mentioned shortcoming, provides a kind of and can guarantee that normal production, location are easy to easily fixedly crystal pulling tube.
The technical solution of the utility model is achieved in that easily fixedly crystal pulling tube, comprise the crystal pulling tube body, the crystal pulling tube body is that the end that glass is made seals, the tubular structure of an end opening, it is characterized in that: the locating structure that depression is arranged in the middle of described crystal pulling tube body exterior.
Further say, described locating device is the ring structure of depression.
Perhaps, described locating structure is the planarized structure in crystal pulling tube body both sides.
Further say, described locating structure is two, and two locating structures arrange near two ends at the crystal pulling tube body.
The beneficial effects of the utility model are: such crystal pulling tube has can guarantee normal production, it is easy to locate, not breakable advantage in crystal pulling furnace.
The accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Wherein: 1, crystal pulling tube body 2, locating structure.
