Quartz Diffusion Tube

Semixlab's Quartz Diffusion Tubooyinka waa saafi-sare, qaybaha kulaylka leh ee quartz-ka ah oo loogu talagalay fidinta, oksaydheynta, iyo habsocodyada nuugista ee wax soo saarka semiconductor. Waxaa loo farsameeyay si ay ugu shaqeeyaan xaaladaha kulaylka aadka u daran, tuubooyinkani waa qaybo lama huraan ah oo ku jira hababka foornada tooska ah iyo kuwa toosan ee loo isticmaalo unugyada qorraxda.

Ⅰ.Abuuritaanka agabka

Tuubooyinka faafinta waxaa laga sameeyay 99.995% silica fused saafi ah (SiO₂), oo laga keenay alaab-qeybiyeyaasha heerka-sare ee alaabta ceeriin waxaana lagu farsameeyay iyadoo la adeegsanayo farsamooyinka samaynta kulaylka lahaanshaha iyo soo celinta. Tani waxay hubinaysaa caabbinta gaarka ah ee shoogga kulaylka, xasiloonida kiimikada, iyo wasakhowga ugu yar ee ionic - arrimo muhiim ah oo lagu ilaalinayo wax-soo-saarka waferka iyo daacadnimada qalabka.

● Qalab: Silica Isku-dhafka ah ee Nadiifinta Sare leh

● Heerka wasakhda: ≤10 ppm ( wasakhda birta ah)

● Dhismaha Crystal: Amorphous

Ⅱ.Codsiyada muhiimka ah ee habaynta Semiconductor

Semixlab's Quartz Diffusion Tubooyinka waa lagama maarmaan noocyo kala duwan oo ah tillaabooyinka abuuritaanka semiconductor ee muhiimka ah, iyagoo door muhiim ah ka ciyaaraya gaaritaanka alaabada la doonayo iyo waxqabadka aaladda:

Nidaamyada Faafinta

Foornooyinka fidinta, tuubooyinkeenu waxay u adeegaan sida qolka falcelinta halkaasoo wasakhda dopant (tusaale, boron, fosfooraska, arsenic) lagu soo bandhigo maraqyada semiconductor ee heerkul sarreeya. Tuubooyinku waxay bixiyaan deegaan aan wasakhayn lahayn oo hermetically xiran si loo xakameeyo astaamaha doping-ka. Degganaanshahooda kulaylku waxay hubisaa qaybinta heerkulka isku midka ah, taasoo horseedaysa dhexgalka dopant joogto ah iyo firfircoonida, taas oo muhiim u ah qeexidda sifooyinka korantada ee qalabka.

Hababka oksidaynta

Inta lagu jiro oksaydhka kulaylka, maraqyada silikoonku waxay la kulmaan ogsijiin ama uumiga biyaha heerkulka sare ee tuubada quartz si ay u koraan lakab khafiif ah, lakabka dahaaran ee Silicon dioxide (SiO₂). Lakabkan SiO₂ wuxuu u shaqeeyaa sidii dielectric gate, lakabka go'doominta, ama lakabka passivation. Nadiifinta sare iyo xasiloonida cabbirka ee tuubooyinkeena ayaa muhiim u ah halkan, maadaama ay si toos ah u saameeyaan isku-dhafka, dhumucda, iyo tayada korantada ee lakabka oksaydhka, kuwaas oo aasaas u ah waxqabadka qalabka iyo kalsoonida.

Nidaamyada tirtiridda

Annealing waxaa loo isticmaalaa in lagu hagaajiyo burburka shabagga crystal ee ay sababtay ion implantation iyo in la dhaqaajiyo dopants la rakibay. Tuubooyinkeena quartz waxay bixiyaan jawi heerkul sare oo nadiif ah oo la xakameeyey lagama maarmaanka u ah tillaabooyinkan tirtiridda. Tilmaamaha kulaylka ee aadka u fiican ee quartz waxay xaqiijiyaan daaweynta kulaylka isku midka ah ee guud ahaan waferka, taasoo horseedaysa dhimista cillad wax ku ool ah iyo firfircoonida dopant-ka ugu fiican, taas oo si weyn u wanaajisa sifooyinka korantada ee qalabka iyo xasilloonida muddada dheer.
