Ubwato bwa Quartz Wafer ni iki?

Ubwato bwa Quartzni igikoresho cyihariye gikoreshwa mu gukora semiconductor, cyane cyane mu gutwara no gutwara wafer za silicon mu bushyuhe bwinshi. Bitewe n'uko zirwanya ubushyuhe bwinshi kandi zigakomera, ubwato bwa quartz wafer bukoreshwa cyane mu bintu byinshi bikenewe mu buryo bunonosoye kandi bugezweho. Ubusanzwe bukorwa mu bikoresho bya quartz bifite isuku nyinshi (SiO2), bidatuma ubushyuhe buhora neza gusa mu bushyuhe bwinshi ahubwo binatuma imiti ihora ihindagurika, bikarinda imyuka cyangwa imiti kwanduza wafer.
Mu gikorwa cyo gukora ibikoresho bya semiconductor, cyane cyane muri fotolithography, thin film deposition, etching n'izindi gahunda, wafers zigomba gutunganywa ku bushyuhe bwinshi kandi akenshi zikenera gukora ibikorwa mu kirere cyihariye. Muri iki gikorwa, wafer boat, nk'umutwaro, ishobora gushyigikira no gutwara wafers neza, ikareba ko ubuso bwa wafer butanduye kandi ikagabanya kwangirika cyane.

Porogaramu

1.Gukora ibikoresho bya semiconductor
Inganda za semiconductor ni zo zikoreshwa cyane mu bwato bwa quartz wafer. Ubwato bwa Wafer bukunze gukoreshwa mu gukora ibyuma bihuza (IC), harimo no gushyiramo icyuma gito (nk'ingufu za chemical na physical vapor deposition) ndetse no gukoresha ubushyuhe bwinshi nko gushyiramo oxidation na annealing. Muri ibi bikorwa, ubwato bwa wafer bufite inshingano zo gutwara wafers mu buryo bumwe muri reactor no kugenzura ko zishyushye neza mu gihe cyose cy'igikorwa.
2. Gushyira umwuka mu kirere (CVD)
Mu buryo bwa CVD, ubwato bwa quartz bushobora gutwara wafers mu buryo butajegajega ku bushyuhe bwinshi kugira ngo habeho ingano imwe y’ibice byayo kandi bigabanye kwanduzanya kwa shimi. Bitewe n’imiterere y’ubwato bwa wafers, bushobora kwirinda kubangamirana kw’ibinyabutabire mu gihe cya CVD, bityo bukagenzura ubwiza bwa wafers.
3. Uburyo bwo gufunga
Annealing ni igikorwa gisanzwe mu gikorwa cyo gukora semiconductor, gikubiyemo gushyushya wafer kugira ngo ikureho stress imbere cyangwa isane n'ibindi bintu. Boti za Quartz wafer zikoreshwa muri ubu buryo mu gutwara wafer no kwemeza ko zishyushya neza mu itanura.
4. Gukura kw'amakristaro
Mu gukora ibikoresho bimwe na bimwe bigezweho, ubwato bwa quartz bushobora no gukoreshwa mu mikorere yo gukura kwa kristu, cyane cyane mu mikurire ya kristu imwe ya silicon n'ibindi bikoresho bya semiconductor. Muri ubu buryo, ubushobozi bwo guhangana n'ubushyuhe bwinshi n'ubudahangarwa bw'imiti bwa kristu ni ingenzi cyane.

Igishushanyo mbonera cy'ubwato bwa quartz wafer kigomba kuzuza ibisabwa byinshi:

• Ubudahangarwa bw'ubushyuhe bwinshi:Ahantu ho gushonga kw'ibikoresho bya quartz hari hejuru ya 1600°C, bituma ikomeza kugumana ubusugire bw'umubiri n'ubw'imiti mu bidukikije birimo ubushyuhe bwinshi.
• Ubudahangarwa bw'ihungabana ry'ubushyuhe:Quartz ifite ubushobozi bwo kwihanganira ubushyuhe, ishobora kwitwara neza mu gihe cy’impinduka z’ubushyuhe, kandi ntikunda gucikagurika.
• l Nta mwanda uhumanya:Quartz ni ibikoresho bisukuye cyane bishobora gukumira kwanduza ubuso bwa wafer. Mu gikorwa cyo gukora semiconductor, ubwandu buto bushobora gutera inenge ku bicuruzwa, bityo guhitamo ibikoresho bya quartz ni ingenzi cyane.

Ni gute wahitamo ubwato bwa Quartz Wafer?

1. Umubare n'ingano ya wafers
Uburyo butandukanye bwo gukora bufite ibisabwa bitandukanye ku bwato bwa wafer. Muri rusange, ingano y'ubwato bwa wafer, umubare w'aho buherereye, nibindi bigomba kugenwa hashingiwe ku bunini n'ingano y'ubwafer bugomba gutunganywa. Wafer nyinshi zishobora kugira ingaruka ku gukwirakwiza ubushyuhe n'uburyo bungana, bityo rero hakenewe kwitabwaho neza mu gihe cyo gushushanya no guhitamo.
2. Ibikoresho bya quartz bifite isuku nyinshi
Bitewe n’uko isuku ikenewe cyane mu ikorwa rya semiconductor, guhitamo ibikoresho bya quartz bifite isuku nyinshi ni ingenzi cyane. Quartz ifite isuku nke ishobora kwanduza wafers, bigatuma ireme ry’ibicuruzwa rigabanuka.
3. Ubudahangarwa bw'ubushyuhe
Mu buryo bumwe na bumwe, ubwato bwa wafer bugomba guhindagurika kenshi hagati y’ubushyuhe butandukanye, bityo ubushobozi bwo guhangana n’ubushyuhe ni ingenzi cyane. Ibikoresho bya Quartz ubwabyo bifite ubushobozi bwo guhangana n’ubushyuhe, ariko ubushobozi bwo guhangana n’ubushyuhe bw’ubwato bwa quartz bwakozwe n’inganda zitandukanye bushobora gutandukana.
4. Ubudahangarwa bw'inkongi n'ubudahangarwa bw'imiti
Ibikoresho bya shimi bikoreshwa mu nganda za semiconductor akenshi birangiza cyane, bityo ubwato bwa quartz wafer bugomba kugira ubushobozi bwo gupima ubuziranenge kugira ngo hirindwe ingaruka z’ibi bintu bya shimi.
5. Ikiguzi n'igihe cy'ubuzima
Kubera ko ibikoresho byo gutwara quartz bikorera ahantu hashyuha cyane, bikunze kwangirika. Kubwibyo, igihe bimara ni ikintu kigomba kwitabwaho. Guhitamo ubwato bwo gutwara quartz buhendutse bishobora kugabanya ikiguzi cyo gukoresha mu gihe kirekire.

 Nigute wakora neza ubwato bwa Quartz Wafer?

1. Isuku
Mu gihe cyo gukoresha, ubwato bwa quartz bushobora gukusanya ibintu bimwe na bimwe bya shimi cyangwa uduce duto, bishobora kugira ingaruka ku bwiza bwa wafer. Kubwibyo, ni ngombwa cyane gusukura ubwato bwa wafer buri gihe. Uburyo busanzwe bwo gusukura burimo gukoresha imashini zisukura hakoreshejwe ikoranabuhanga, gukaraba aside, no gusukura isuku, nibindi.
2. Reba niba hari imivuniko n'ibyangiritse
Bitewe n'uko ubwato bwa quartz buhura n'ubushyuhe bwinshi cyane n'umuvuduko wa mekanike, bishobora kwangirika cyangwa kwangirika nyuma yo gukoreshwa igihe kirekire. Suzuma buri gihe imiterere y'ubwato bwa wafer kandi usimbuze ibice byangiritse ku gihe kugira ngo wirinde ibibazo mu gihe cyo kubukora.
3. Irinde ubushyuhe bukabije
Nubwo quartz ifite ubushobozi bwo guhangana n’ubushyuhe bwinshi, ishobora kwangirika mu bihe bimwe na bimwe bikomeye. Kubwibyo, mu gihe ikora, ni ngombwa kwitondera kwirinda ubushyuhe bwinshi cyane n’ubushyuhe bwinshi.
