Abstract
The utility model discloses an integrated heat-shielding lifting appliance comprising a body part positioned in a separating valve. The integrated heat-shielding lifting appliance is characterized by also comprising a seed crystal clamping head specially used for suspending seed crystals and a heat-shielding hook used for suspending the heat shield; the seed crystal clamping head and the heat-shielding hook are arranged at the bottom of the body and extend into a furnace cover. The integrated heat-shielding lifting appliance combines the seed crystal clamping head and the heat-shielding hook together organically, and is non-interfering between the two types of functions. Therefore, integrated heat-shielding lifting appliance greatly saves more operating steps and operation time, not only improves safety of the operation, but also greatly reduces the production cost.
Description
Technical field
The utility model relates to the suspender that is used to hang heat shielding in a kind of single crystal growing furnace, particularly be a kind of suspention seed crystal and integral type heat shielding suspender that hangs two functions of heat shielding of integrating.
Background technology
In the growth of monocrystal semiconductor, mostly be to utilize Czochralski method manufacturing (being called for short CZ) method.In this method, high-purity polycrystalline is packed in the quartz crucible by certain requirement, heat quartz crucible then, polysilicon is wherein dissolved, next will melt silicon and lower the temperature slightly, giving must condensate depression, wait molten silicon static determinacy after, the standard silicon single crystal of one Gent system (being seed crystal usually) is contacted gold with molten silicon carry out seeding, seeding begins shouldering (it is big that boule diameter becomes) behind suitable length, promptly beginning after a while changes shoulder, promptly enters the isodiametric growth stage subsequently, this time length in stage can be very long, length on crystal pulling is decided, and reaching design requirements can finish up, crystal bar cooling after ending finishes, take out single crystal, promptly finish a crystal pulling.
How improving crystal pulling efficient in the above-mentioned crystal pulling process and cutting down the consumption of energy is the emphasis of this area research always, in known patent documentation and the actual monocrystal stove that uses, special-purpose heat shielding and the special-purpose heat shielding suspenders of adopting more, as shown in Figure 1, special-purpose heat shielding suspender 1 is installed in the segregaion valve 2 and extends in the bell 3, and the hook 11 on the special-purpose heat shielding suspender 1 is sling heat shielding 4 and is suspended in the bell 3.Owing to after having changed material, will from segregaion valve 2, take out with special-purpose heat shielding suspender 1, destroyed the vacuum of body of heater, cause body of heater gas leakage and cause normally crystal pulling, and after the heat shielding suspender 1 that takes out special use is changed seed crystal, from newly stablize this process, approximately want about more than one hour consuming time again, increased the expenditure of the electricity charge, thermal field cost, again because the long time, the transparent layer thickness of understanding the attenuate quartz crucible like this reduced the chance of successfully pulling out monocrystalline.
The utility model content
The utility model has overcome above-mentioned shortcoming, and a kind of suspention seed crystal and integral type heat shielding suspender that hangs two functions of heat shielding and one of collecting is provided.
To achieve these goals, the utility model is to realize by the following technical solutions:
Integral type heat shielding suspender, it comprises a body part that is positioned at segregaion valve, it is characterized in that, comprise that also one is specifically designed to the seed chuck of suspention seed crystal and in order to suspend the heat shielding hook of described heat shielding in midair, seed chuck and heat shielding hook are installed in the bottom of described body and extend in the bell.
The utility model integral type heat shielding suspender is that seed chuck and heat shielding suspension hook are combined, and two functions are not all disturbed mutually.Save a lot of operation stepss greatly, saved the time of operation, both improved the security of operation, significantly reduced production cost again.
Description of drawings
Describe the utility model in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structure and the scheme of installation of existing heat shielding suspender.
Fig. 2 is the structure and the scheme of installation of the utility model integral type heat shielding suspender.
Embodiment
For technique means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with embodiment, further set forth the utility model.
With reference to figure 1, integral type heat shielding hook of the present utility model, it comprises body 100 parts that are positioned at segregaion valve 2, comprise that also one is specifically designed to the seed chuck 110 of suspention seed crystal 5 and links up with 120 in order to the heat shielding of suspention heat shielding 4, seed chuck 110 and heat shielding hook 120 are installed in the bottom of body 100 and extend in the bell 3.Heat shielding 4 hangs on the top of bell 3 by heat shielding hook 120, and seed crystal 5 is suspended in the heat shielding 4 by seed chuck 110.
The use of heat shielding 4 should be commonplace in solar-electricity magnetic sheet manufacturing, its effect can reduce single crystal growing furnace power consumption, improve the speed that becomes brilliant, flow direction of rectification argon gas or the like.Referring to Fig. 1, when using heat shielding 4 in the past, during changing material in order not influence heat shielding suspender 1 hang-up of usually that heat shielding 4 usefulness shapes are the similar special use with seed chuck 110 of charge amount, open upper furnace body again behind the intact material of waiting and take out this special-purpose heat shielding suspender 1, load onto seed crystal and continue crystal pulling, this way must be destroyed the body of heater vacuum and take out suspender from segregaion valve 2 tops, so destroyed the vacuum of body of heater, cause body of heater gas leakage and cause normally crystal pulling, take out the heat shielding suspender simultaneously and change seed crystal 5 again from the about needs of new uncertain this process about hour, efficient and low.
Adopt integral type heat shielding suspender of the present utility model, changing material and crystal pulling all carries out in single crystal growing furnace, saved and opened the operation that bell is reinstalled seed chuck 110, after at first changing the material end, decline heat shielding 4, assemble after making heat shielding 4 arrive the position of setting, seed chuck 110 beginning preheatings when the silicon liquid temp is stable, make heat shielding 4 give full play to the effect that reduces the single crystal growing furnace power consumption, improves the speed that becomes brilliant like this, this integrated operation of finishing, need not open single crystal growing furnace, and the vacuum of not destroying body of heater is carried out the crystal pulling process rapidly.
More than show and described ultimate principle of the present utility model and principal character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification sheets just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
