Abstract
The utility model discloses a molybdenum rod for a monocrystal furnace, which comprises a rod body, wherein the upper end of the rod body is fixedly sleeved in a wire-drawing sleeve; an arc hook-shaped groove is formed on the side wall at the upper end of the rod body; a pin shaft, transversely penetrating the hook-shaped groove, is arranged in the wire-drawing sleeve; a steel wire is connected to the upper end of the wire-drawing sleeve; and a seed crystal is fixed at the lower end of the rod body. By adopting a buckling structure, the molybdenum rod provided by the utility model has the advantages that the mounting is more convenient and quicker, the service life is prolonged, and the manufacturing cost is reduced.
Description
Technical field
The utility model relates to and utilizes polycrystalline to lift out the silicon single crystal field, specifically belongs to the molybdenum bar of single crystal growing furnace.
Background technology
At present, czochralski crystal growing furnace is a most important product line in the crystal growth equipment, makes artificial lens with it, and crystalline growth velocity is the highest, realizes MC the most easily, has therefore also obtained to use the most widely.In order to grow large size and high-quality monocrystalline, human all advanced means of almost having used.Integrated material, machinery, electric, computingmachine, the many-sided high-end knowledge and technology of magnetic on single crystal growing furnace.Silicon single crystal generally is used to make unicircuit and other electronic components as a kind of semiconductor material.Most semiconductor silicon single crystal body adopts the vertical pulling method manufacturing.
The utility model content
The purpose of the utility model provides a kind of molybdenum bar of single crystal growing furnace, adopts the buckle-type structure, and easier for installation quick, prolong work-ing life, and production cost reduces.
The technical scheme of the utility model is following:
The molybdenum bar of single crystal growing furnace includes barred body, and the upper end permanent sleeve of barred body is loaded in the wire drawing cover; Have arcual hook groove on the upper end sidewall of said barred body; Be provided with the bearing pin that passes across the hook groove in the wire drawing cover, the upper end of wire drawing cover is connected with steel wire, and the lower end of barred body is fixed with seed crystal.
The lower end of described barred body is provided with groove, and seed crystal is fixed in the groove.
Adopt the buckle-type structure between wire drawing cover of the utility model and the barred body, easier for installation quick, prolong work-ing life, and production cost reduces.
