The High Purity Quartz Crucible for Melting ke Semixlab e etselitsoe ho fihlela litlhoko tse thata tsa semiconductor ea sejoale-joale le tlhahiso ea photovoltaic. Ka bohloeki bo phahameng, ho hanyetsa mocheso o babatsehang, le ho tšepahala ho netefalitsoeng, e tiisa ts'ebetso e tsitsitseng ho pholletsa le ho qhibiliha ho hoholo, khōlo ea kristale, le mekhoa ea sebōpi se phahameng sa mocheso. Joaloka moetsi ea ka sehloohong oa Sechaena le mofani oa thepa ea High Purity Quartz Crucible, Semixlab e lebeletse ka tieo ho ba molekane oa hau oa nako e telele Chaena.

Likopo tse qaqileng tsa High Purity Quartz Crucible

1. Ts'ebetso ea Czochralski (CZ).

Ts'ebetso ea Czochralski ke mokhoa o ka sehloohong oa ho hlahisa li-ingots tsa silicon tsa monocrystalline, tseo hamorao li arotsoeng ka li-wafers bakeng sa lipotoloho tse kopantsoeng le lisebelisoa tsa matla. Ts'ebetsong ena, polysilicon e kenngoa ka har'a crucible ea quartz mme e qhibilihisoa mocheso o ka holimo ho 1,420 ° C.

Karolo ea Quartz Crucible:

● E fana ka setshelo se inelang ka lik'hemik'hale se mamellang khatello e feteletseng ea mocheso nakong ea ho qhibiliha ho tsoelang pele.

● E netefatsa hore litšila li kena ka har'a silicon e qhibilihisitsoeng, e thibelang tšoaetso e sa batleheng ea dopant.

● Ponahatso ea eona ea optical le botsitso ba sebopeho li thusa ho beha leihlo ka nepo le ho hula ka mokhoa o ts'oanang oa kristale.

● E fokotsa ho tsoa ha oksijene le ho hlahisa bubble, ka bobeli ba bohlokoa bakeng sa ho hlahisa li-ingots tse se nang sekoli.

Ntle le crucible ea quartz e hloekileng haholo, ts'ebetso ea CZ e kotsing ea ho hlahisa li-wafers tse nang le tšilafalo ea tšepe kapa li-micro-defects, tse amang ts'ebetso ea sesebelisoa sa semiconductor ka kotloloho.

2. Mekhoa ea Doping le Melting

Doping ke kenyelletso e laoloang ea litšila tse itseng ka har'a silicon e qhibilihisitsoeng ho lokisa conductivity ea eona ea motlakase (n-type kapa p-type), e hlalosang ts'ebetso ea lisebelisoa tsa semiconductor. Mohato ona hangata o etsahala ha silicon e qhibiliha ka har'a crucible ea quartz.

Karolo ea Quartz Crucible:

● E sebetsa e le sekepe se tsitsitseng se khonang ho mamella ho kenngoa ha dopant (mohlala, boron, phosphorus, arsenic) ntle le ho sebelisana le lik'hemik'hale.

● E boloka ho tšoana ha mocheso ha ho qhibiliha, e leng ntho ea bohlokoa bakeng sa ho finyella tšebelisano e nepahetseng ea dopant ho pholletsa le kristale.

● E thibela tšilafalo ka lebaka la bohloeki ba eona bo phahameng ka ho ikhethang, e netefatsa hore lisebelisoa tsa motlakase li lula li le teng ka har'a li-wafer.

● E mamella ho futhumatsa le ho pholisa khafetsa nakong ea li-doping tse ngata ntle le deformation.

Ka ho nolofalletsa tikoloho e hloekileng le e tsitsitseng ea doping, crucible ea quartz e tiisa hore lisebelisoa tsa semiconductor li finyella litlhoko tse thata bakeng sa ho hanyetsa le bophelo bohle ba mojari.

3. Oxidation & Diffusion Furnaces

Oxidation le diffusion ke mekhoa e 'meli ea mocheso o phahameng e sebelisoang ho li-wafers tsa silicon ho etsa likarolo tse sireletsang metsi (SiO₂) kapa ho hlahisa liathomo tse dopant. Mehato ena e hloka litlhophiso tsa sebōpi tse bolokang moea o hloekileng, o tsitsitseng le o laoloang. Li-crucible tsa quartz li bohlokoa lits'ebetsong tsena.

Karolo ea Quartz Crucible:

● E fana ka tšireletso bakeng sa li-wafers kapa lik'hemik'hale tlas'a libaesekele tse matla tse fihlang ho 1,200°C.

● E boloka lik'hemik'hale li sebetsa sebakeng se nang le oksijene kapa sepakapaka se nang le dopant, e thibelang ho silafala ha liphaphatha.

● E netefatsa botsitso ba mochine le ho hanyetsa microcracking nakong ea nako e telele ea sebōpi.

● Qetello ea eona e boreleli le homogeneity e phahameng e fokotsa tlhahiso ea likaroloana, e leng ea bohlokoa bakeng sa node e tsoetseng pele ea semiconductor.

Ka ho sebelisa li-crucible tsa quartz tse hloekileng ka har'a libopi tsa oxidation le diffusion, bahlahisi ba fumana boleng bo holimo ba bokaholimo, bofokoli bo fokotsehileng, le tlhahiso e phahameng ea lisebelisoa.
