Iyada oo nadiifnimo sare leh, caabbinta kulaylka aadka u fiican, iyo isku halaynta la xaqiijiyay, waxay hubisaa waxqabadka xasilloon ee dhalaalidda muhiimka ah, koritaanka crystal, iyo hababka foornada heerkul sare. Sida hormuudka soo saaraha Shiinaha iyo alaab-qeybiyaha High Purity Quartz Crucible, Semixlab wuxuu si daacad ah u rajeynayaa inuu noqdo lammaanahaaga muddada-dheer ee Shiinaha.

Codsiyada tafatiran ee Quartz Quartz Crucible oo nadiif ah

1. Habka Czochralski (CZ).

Habka Czochralski waa habka ugu muhiimsan ee lagu soo saaro monocrystalline silicon ingots, kuwaas oo markii dambe loo jarjaray weelal loogu talagalay wareegyada isku dhafan iyo qalabka korontada. Habkan, polysilicon waxaa la dhigayaa gudaha weel quartz ah oo lagu dhalaaliyo heerkul ka sarreeya 1,420 ° C.

Doorka Quartz Crucible:

● Waxay siisaa weel kiimikaad ahaan qallafsan oo u adkeysa diiqada kulaylka ee ba'an inta lagu jiro dhalaalid joogto ah.

● Waxay xaqiijisaa ku faafidda wasakhda hoose ee silikoonka dhalaalaysa, isaga oo ka hortagaya wasakhowga aan la rabin.

● Daahfurnaanteeda indhaha iyo xasilloonida qaabdhismeedkeeda waxay awood u siinaysaa la socodka saxda ah iyo jiidashada kareemka lebbiska ah.

● Waxay yaraynaysaa sii daynta ogsijiinta iyo abuuritaanka xumbo, labaduba waxay muhiim u yihiin soo saarista xinjiro aan cillad lahayn.

La'aanteed quartz nadiif ah oo sarreeya, habka CZ wuxuu halis ugu jiraa soo saarista maraqa wasakhaysan macdan ama cillado yaryar, oo si toos ah u saameeya waxqabadka qalabka semiconductor.

2. Nidaamyada Doping iyo dhalaalay

Doping-ku waa hordhaca wasakh gaar ah oo silikoon dhalaalaysa si loo hagaajiyo socodka korantada (n-nooca ama p-nooca), kaas oo qeexaya shaqada aaladaha semiconductor. Talaabadani waxay caadi ahaan dhacdaa marka silikoonku uu ku dhalaaliyo weel quartz ah.

Doorka Quartz Crucible:

● Wuxuu u shaqeeyaa sidii weel falcelin deggan oo u adkeysanaya soo-bandhigidda dopant (tusaale, boron, fosfooraska, arsenic) iyadoon kiimikaad la falgelin.

● Waxay ku ilaalisaa isku mid ahaanshaha kulaylka ee dhalaalka, taas oo muhiim u ah gaaritaanka fiirsashada saxda ah ee kristanta.

● Waxay ka hortagtaa wasakhaynta isdhaafka iyada oo ay ugu wacan tahay nadiifnimadeeda sare ee gaarka ah, hubinta sifooyinka korantada ee joogtada ah ee maraqyada.

● Waxay u adkaysataa kulaylka iyo qaboojinta soo noqnoqda inta lagu guda jiro dhaq-dhaqaaqyo badan oo aan isbeddel lahayn.

Iyada oo awood u siinaysa jawi nadiif ah oo xasilan, quartz crucible waxay hubisaa in aaladaha semiconductor ay buuxiyaan shuruudaha adag ee iska caabbinta iyo sidaha nolosha.

3. Oxidation & Foornooyinka Faafinta

Oxidation iyo fidinta waa laba hab oo heerkul sare ah oo lagu dabaqo maraqa silikoon si loo sameeyo lakabyo dahamiya (SiO₂) ama soo bandhig atomyada dopant. Talaabooyinkani waxay u baahan yihiin habaynta foornada si ay u ilaaliso nadiif, deggan, iyo jawiga la xakameeyey. Quartz crucibles ayaa lagama maarmaan u ah nidaamyadan.

Doorka Quartz Crucible:

● Waxay siisaa xakamaynta maraqa ama kiimikooyinka hoos yimaada kulaylka kulul ilaa 1,200°C.

● Waxay ilaalisaa daacadnimada kiimikaad ee oksaydhaynta ama jawiga hodanka ku ah dopant, ka hortagga wasakhaynta marawaxadaha.

● Waxay xaqiijisaa xasilloonida farsamada iyo iska caabinta microcracking inta lagu jiro muddada dheer ee foornada.

● Dhammaystirka dusha sare ee siman iyo sinnaanta sare waxay yaraynaysaa jiilka walxaha, oo muhiim u ah qanjidhada semiconductor sare.

Adigoo isticmaalaya qolofyada quartz ee nadiifka ah ee oksaydhka iyo foornooyinka faafinta, soosaarayaashu waxay gaadhaan tayada dusha sare ee wafer, cufnaanta cilladda oo yaraatay, iyo dhalidda aaladda sare.
