Yiziphi ezinye izinto ezisetshenziswayo zezingxenye zegranite kumishini ye-semiconductor?Yiziphi izinzuzo kanye nokubi zalezi zinto ezihlukile uma kuqhathaniswa negwadle?

I-Granite ibe yinto evame ukusetshenziswa embonini ye-semiconductor ngenxa yezakhiwo zayo ezinhle kakhulu zemishini, ukuqina kokushisa, kanye ne-coefficient ephansi yokwanda okushisayo.Kodwa-ke, ngesidingo esihlala sikhula sokunemba okuphezulu nokukhiqiza, ezinye izinto ezisetshenziswayo ziye zavela njengezinketho ezisebenzayo zokwenziwa kwezingxenye zemishini ye-semiconductor.Kulesi sihloko, sizohlola ezinye zezinto ezihlukile zezingxenye ze-granite kumishini ye-semiconductor futhi siqhathanise izinzuzo kanye nokubi.

Ezinye Izinto Ezisetshenziswayo Zezingxenye Zegwadle

1. Izinto ze-Glass-ceramic

Izinto ze-Glas-ceramic, ezifana ne-Zerodur ne-Cervit, zithole ukusetshenziswa okubanzi embonini ye-semiconductor ngenxa ye-coefficient yazo ephansi yokwandisa okushisayo, eseduze naleyo ye-silicon.Ngakho-ke, lezi zinto zinganikeza ukuzinza okungcono kokushisa kanye nokunemba okuthuthukisiwe enqubweni yokwenziwa kwe-semiconductor.I-Zerodur, ikakhulukazi, inezinga eliphezulu le-homogeneity nokuzinza, okwenza ifanele ukukhiqizwa kwemishini ye-lithography.

Izinzuzo:

- I-coefficient ephansi yokwandisa okushisayo
- Ukunemba okuphezulu nokuzinza
- Ifanele izicelo ezisezingeni eliphezulu

Ububi:

- Izindleko eziphakeme uma ziqhathaniswa negwadle
- I-brittle uma iqhathaniswa, ingase ibangele izinselele ekukhiqizeni nasekuphatheni

2. I-Ceramics

Izinto ze-Ceramic, njenge-aluminium oxide (Al2O3), i-silicon carbide (SiC), ne-silicon nitride (Si3N4), zinezakhiwo ezinhle kakhulu zemishini, ukumelana nezinga lokushisa eliphezulu, kanye ne-coefficient ephansi yokwandisa okushisayo.Lezi zakhiwo zenza izitsha zobumba zibe zilungele izingxenye zemishini ye-semiconductor ezidinga ukuzinza okuphezulu nokunemba okushisayo, njengezigaba ze-wafer nama-chucks.

Izinzuzo:

- Ukuqina okuphezulu kokushisa namandla
- I-coefficient yokwandisa okushisayo ephansi
- High ukugqoka ukumelana kanye inertness amakhemikhali

Ububi:

- Kungaba brittle futhi athambekele ekuqhekekeni, ikakhulukazi ngesikhathi machining kanye nokusingatha
- Ukwenza imishini nokupholishwa kwezitsha zobumba kungaba inselele futhi kudle isikhathi

3. Izinsimbi

Izinto ezisekelwe ensimbi, njengensimbi engagqwali kanye ne-titanium, zisetshenziselwe ezinye izingxenye zemishini ye-semiconductor ngenxa yokusebenza kwazo okuhle kakhulu namandla aphezulu.Zivame ukusetshenziselwa izinhlelo zokusebenza lapho ukuzinza okuphezulu kwe-thermal kungadingeki, njengezingxenye zegumbi, ama-couplings, nama-feedthroughs.

Izinzuzo:

-Machinability Good kanye weldability
- Amandla aphezulu kanye ne-ductility
- Izindleko eziphansi uma ziqhathaniswa nezinye izinto ezisetshenziswayo

Ububi:

- I-coefficient yokwandisa ukushisa okuphezulu
- Ayizifanele izicelo zokushisa okuphezulu ngenxa yezinkinga zokwanda kwezinga lokushisa
- Iyakwazi ukugqwala futhi ingcoliswe

Isiphetho:

Kafushane, nakuba i-granite ibe yinto ethandwayo ezingxenyeni zemishini ye-semiconductor, kuye kwavela ezinye izinto, ngayinye inezinzuzo eziyingqayizivele kanye nokubi.Izinto ze-Glas-ceramic zinembe kakhulu futhi zizinzile kodwa zingaba brittle.I-Ceramics inamandla futhi inokuqina okuhle kakhulu kwe-thermal kodwa ingaba brittle, okuwenza kube inselele kakhulu ukuwenza.Izinsimbi azibizi, ziyasebenziseka, futhi zine-ductile, kodwa zine-coefficient ephezulu yokwanda okushisayo futhi zisengozini yokugqwala nokungcola.Lapho ukhetha izinto zokwakha ze-semiconductor, kubalulekile ukucabangela izidingo ezithile zohlelo lokusebenza bese ukhetha izinto ezilinganisa izindleko, ukusebenza, nokuthembeka.
