3. Habka nuugista
Annealing waa hawlgal caadi ah oo ka dhaca habka wax soo saarka semiconductor-ka, kaas oo ku lug leh kululaynta wafer-ka si loo sii daayo cadaadiska gudaha ama loo hagaajiyo cilladaha qaarkood. Doonyaha wafer-ka Quartz ayaa loo isticmaalaa habkan si loo qaado wafer-ka loona hubiyo inay helaan daaweyn kulayl oo isku mid ah foornada.
4. Kobaca kiristaalka
Soo saarista agabyo horumarsan, doonyaha quartz wafer ayaa sidoo kale loo isticmaali karaa hababka koritaanka kiristaalka, gaar ahaan koritaanka kiristaalka silikoon ee keli ah iyo agabka kale ee semiconductor-ka. Codsiyadan, iska caabbinta heerkulka sare iyo xasilloonida kiimikada ee doonyaha quartz ayaa muhiimad muhiim ah leh.
Naqshadaynta doomaha quartz wafer waxay u baahan tahay inay buuxiso shuruudo badan:
- Xasiloonida heerkulka sare:Barta dhalaalka ee walxaha quartz waxay ka sarreysaa 1600°C, taasoo u sahlaysa inay ilaaliso xasilloonida jireed iyo tan kiimikada ee jawiga heerkulka sare leh.
- Iska caabbinta shoogga kulaylka:Quartz wuxuu leeyahay iska caabin heer sare ah oo kulka ah, si dhakhso ah ayuu ula qabsan karaa isbeddellada heerkulka, mana u nugul yahay inuu dillaaco.
- l Wasakh la'aan:Quartz waa walax aad u saafi ah oo ka hortagi karta wasakhowga dusha sare ee wafer-ka. Habka wax soo saarka semiconductor-ka, wasakh kasta oo yar ayaa keeni karta cillado alaab ah, sidaa darteed xulashada walxaha quartz waa muhiimad muhiim ah.
Sidee loo doortaa Doonta Quartz Wafer?
1. Tirada iyo cabbirka buskudka
Habab kala duwan oo wax soo saar ah ayaa leh shuruudo kala duwan oo loogu talagalay doomaha wafer-ka. Guud ahaan, cabbirka doonida wafer-ka, tirada godadka, iwm. waa in lagu go'aamiyaa iyadoo lagu saleynayo cabbirka iyo tirada wafer-ka la farsameynayo. Wafer-ka xad-dhaafka ah wuxuu saameyn karaa qaybinta kulaylka iyo isku-midnimada, sidaa darteed waxaa loo baahan yahay tixgelin sax ah inta lagu jiro naqshadeynta iyo xulashada.
2. Walax saafi ah oo saafi ah
Maadaama shuruudaha nadaafadda ee aadka u sarreeya ee habka wax soo saarka semiconductor-ka, xulashada walxaha quartz-ka ee saafiga ah ayaa muhiimad weyn leh. Quartz-ka nadiifnimada hoose leh ayaa wasakheyn kara buskudka, taasoo horseedi karta hoos u dhac ku yimaada tayada badeecada.
3. Iska caabbinta shoogga kulaylka
Habab qaar, doonyaha wafer-ka ah waxay u baahan yihiin inay si joogto ah ugu kala beddelaan jawi heerkul oo kala duwan, sidaa darteed iska caabbinta shoogga kulaylka ayaa muhiimad weyn leh. Walxaha quartz-ka laftoodu waxay leeyihiin iska caabbin shoogga kulaylka oo wanaagsan, laakiin iska caabbinta shoogga kulaylka ee doonyaha wafer-ka quartz-ka ah ee ay soo saaraan soosaarayaal kala duwan way kala duwanaan karaan.
4. Iska caabbinta daxalka iyo xasilloonida kiimikada
Waxyaabaha kiimikada ee loo isticmaalo wax soo saarka semiconductor-ka badanaa waa kuwo aad u daxal badan, sidaa darteed doonyaha quartz wafer waxay u baahan yihiin inay yeeshaan xasillooni kiimiko oo sareysa si looga fogaado falcelinta walxahan kiimikada ah.
5. Qiimaha iyo Cimriga
Maadaama ay sideyaasha wafer-ka quartz ka shaqeeyaan jawi heerkul sare leh, waxay inta badan la kulmaan jirro iyo jeexjeex. Sidaa darteed, cimrigooda adeeggu sidoo kale waa arrin u baahan in la tixgeliyo. Doorashada doon wafer ah oo kharash-ool ah waxay si wax ku ool ah u yareyn kartaa kharashyada hawlgalka muddada-dheer.
Sidee loo ilaaliyaa Doonta Quartz Wafer?
1. Nadiifi
Inta lagu jiro habka isticmaalka, doonyaha quartz wafer waxay ururin karaan walxo kiimiko ah ama walxo yaryar, kuwaas oo saameyn kara tayada wafer-ka.

Sababtoo ah doonyaha quartz-ka ah waxaa la kulma heerkul aad u sarreeya iyo cadaadis farsamo, dildilaac ama xirasho ayaa dhici kara ka dib isticmaalka muddada dheer. Si joogto ah u hubi hufnaanta qaab-dhismeedka doonida wafer-ka ah oo beddel qaybaha dhaawacan si waqtigeeda ah si looga fogaado dhibaatooyinka inta lagu jiro habka wax soo saarka.
3. Ka hortag kulaylka xad-dhaafka ah
In kasta oo quartz uu leeyahay iska caabin shoog kuleyl oo wanaagsan, haddana waxaa laga yaabaa inuu wali dhaawacmo xaalado aad u daran awgood. Sidaa darteed, marka la shaqeynayo, waxaa lagama maarmaan ah in fiiro gaar ah loo yeesho ka fogaanshaha heerkulka aadka u sarreeya iyo shoog kuleyl.
