Kusiyana pakati pa polysilicon ndi monocrystalline silicon

Silicon zinthu ndi zinthu zofunika kwambiri komanso zoyambira kwambiri mu ma semiconducy. Njira yovuta kupanga ya semiconducy yamakampani iyeneranso kuyamba chifukwa chopanga silic.

Moocrystalline silicon dzuwa lipenga

Moncrystalline silicon ndi mtundu wa utali wokhazikika. Pamene chinsalu chambiri chikafika, ma atomu a silikicon amakonzedwa mu diamondi yomanga ma crystal. Ngati ma crystal erclei amakula ndi mawonekedwe omwewo a ndege ya kristalo, mbewuzi zimaphatikizidwa ofanana ndi cystallry mu socrystalline.

Moncrystalline silicon ali ndi zinthu zakuthupi za quasi-zitsulo ndipo zakhala ndi mawonekedwe ofooka, omwe amawonjezeka ndi kutentha kwambiri. Nthawi yomweyo, monocrystalline silicon imakhalanso ndi mawonekedwe ofunikira a semi-carrical. Ultra-yoyera yancrystalline silicon ndi semictictic semicoctictor. Njira ya nducon yamphamvu ya monocrystal imatha kusintha powonjezera zigawo za ma ⅲa (monga Boron), ndi A Boron), ndi P-Villan Silicon Sermicon akhoza kupangidwa. Monga kuwonjezera pa truce za ⅴa (monga phosphorous kapena arsenic) amathanso kusintha simu yailicon semiconductor.

Polysiliconkuwala kwa dzuwa

Polysilicon ndi mtundu wa siteri yokhazikika. Pamene chinsalu chambiri chikakhazikika pansi pa zovuta zapamwamba, ma atomu a silcon amakonzedwa m'magawo ambiri a galasi la ma celendi. Ngati ma crystal erlic uwu akayamba kumera ndi makirtal osiyanasiyana, mbewuzi zimaphatikizana ndi crystallize kukhala polysicicon. Imakhala ndi sinayi ya Monocrystalline, yomwe imagwiritsidwa ntchito m'magawo zamagetsi ndi maselo a dzuwa, ndi silikaus, zomwe zimagwiritsidwa ntchito pazida zowonda komansoMa cell a SANDER Shoright

Kusiyana ndi kulumikizana pakati pa awiriwo

Ku Socrystalline silicon, mawonekedwe a galasi ndi yunifolomu ndipo amatha kuzindikirika ndi mawonekedwe apanja. Ku Socrystalline silicon, malo a kristalo a sampuli yonseyo amakhala osapitilira ndipo alibe malire a tirigu. Makristali akuluakulu amodzi ndi osowa kwambiri m'chilengedwe komanso ovuta kupanga labotale (onani Recystallization). Mosiyana ndi izi, maudindo a maatomu m'magulu a amorphous amangolekeredwa kuti asunge.

Polycrystalline ndi magawo a subcrystalline amakhala ndi makhiristo ambiri kapena ma microcrystals. Polysilicon ndi chinthu chopangidwa ndi makhiristo ambiri ang'onoang'ono. Maselo a Polycrystalline amatha kuzindikira mawonekedwe ndi zitsulo zowoneka. Semiconductor amakanema kuphatikizapo polysilicon polysilicon amasinthidwa kukhala monocrystalline silicon, kutanthauza kuti makhiristo olumikizidwa mwachisawawa amasandulika kukhala kristalo yayikulu. Sacrystalline silicon amagwiritsidwa ntchito popanga zida zambiri za microectronic zochokera ku Microectronic. Polysilicon amatha kukwaniritsa 99.9990% yoyera. Ultra-yoyera imagwiritsidwanso ntchito mu semiconducy mafakitale, monga 2 - mpaka 3-mita ndodo yayitali. M'makampani a microectronics, polysilicon ali ndi mapulogalamu ku masikelo onse a Macro ndi Micro. Njira zopanga za monocrystalline zimaphatikizapo njira ya Czeckorasky, dera losungunuka ndi bridgman.

Kusiyana pakati pa polysilicon ndi monocrystalline silicon kumawonekera makamaka mu thupi. Pankhani ya zamagetsi ndi zamagetsi, polysilicon ndi yotsika ku Monocrystalline silicon. Polysilicon itha kugwiritsidwa ntchito ngati zopangira zojambula za monrystalline silicon.

1. Malinga ndi anisotropy of makina, zowoneka bwino komanso zopatsa mphamvu, sizodziwikiratu kuposa soocrystalline silicon

2. Malinga ndi zamagetsi, zamagetsi za sikicon ya polycrystalline ndizosafunikira kwenikweni kuposa za monocrystalline silicon, kapena ngakhale palibe mawonekedwe amagetsi

3, pokhudzana ndi ntchito zamankhwala, kusiyana pakati pa awiriwo ndikochepa kwambiri, kugwiritsa ntchito polysilicon kwambiri
