Ukuthandwa kwamagesi ahlanzekile aphezulu e-Ultra-High ngokukhiqizwa kwe-semiconductor

Amagesi wokuhlanza aphezulu aphezulu abalulekile kuwo wonke ama-semiconductor ahlinzekwa. Eqinisweni, ngendwangu ejwayelekile, amagesi ahlanzekile aphezulu yizindleko ezinkulu ezibonakalayo ngemuva kweSilicon uqobo. Ngemuva kokushoda kwe-chip ye-Global chip, imboni iyanda ngokushesha kunangaphambili - nesidingo samagesi aphezulu ahlanzekile ayanda.

Amagesi amaningi asetshenziswa kakhulu ekukhiqizweni kwe-semiconductor yi-nitrogen, i-helium, i-hydrogen kanye ne-argon.

Ni-irogen

UNitrogen wenza ama-78% omkhathi wethu futhi ugcwele kakhulu. Kuyenzeka futhi ukuthi ku-inert ngamakhemikhali futhi kungashayeli. Ngenxa yalokhu, i-nitrogen ithole indlela ethile yezimboni eziningi njengegesi esebenza ngemali engenazindleko.

Umkhakha we-semiconductor ungumthengi omkhulu we-nitrogen. Isitshalo sokukhiqiza se-semiconductor sanamuhla kulindeleke ukuthi sisebenzise amamitha ayi-50 000 amamitha ama-nitrogen ngehora. Emikhiqizweni ye-semiconductor, i-nitrogen isebenza njengenhloso ejwayelekile yokuhlanza nokuhlanza igesi, ukuvikela ama-silicon ama-silicon abucayi avela ku-oksijini esebenzayo kanye nomswakama emoyeni.

Alulimoni

I-Helium ingugesi we-inert. Lokhu kusho ukuthi, njenge-nitrogen, i-helium indert ngamakhemikhali - kepha futhi inenzuzo eyengeziwe yokuvuka okuphezulu okushisayo. Lokhu kuwusizo ikakhulukazi ekukhiqizweni kwe-semiconductor, okuvumela ukuthi kuqhube kahle ukushisa kude nezinqubo ezinamandla futhi kusize ukuvikela ngomonakalo oshisayo kanye nokusabela kwamakhemikhali okungafuneki.

I-hydrogen

I-Hydrogen isetshenziswa kakhulu kuyo yonke inqubo yokukhiqiza i-elekthronikhi, futhi ukukhiqizwa kwe-semiconductor akufani. Ikakhulu, i-hydrogen isetshenziselwa:

Ukuncishiswa: I-Silicon Wafers ngokuvamile ifudunyezwa emazingeni okushisa aphezulu futhi ipholile kancane ukulungisa (onamekho) isakhiwo se-crystal. I-Hydrogen isetshenziselwa ukudlulisa ukushisa ngokulinganayo ku-wafer futhi ukusiza ekwakheni kabusha isakhiwo se-crystal.

I-EpiTaxy: I-Hydrogen ehlanzekile ephakeme isetshenziswa njenge-ejenti encishisiwe ku-Epitaxial desition yezinto zokwenziwa ze-semiconductor ezifana ne-silicon ne-terlimanium.

Ukubekwa: I-Hydrogen ingadonswa kumafilimu e-silicon ukwenza isakhiwo sawo se-atomic siphazamiseka kakhulu, sisiza ukukhulisa umhlangano.

Ukuhlanza i-Plasma: I-Hydrogen Plasma isebenza ngokukhethekile ekususeni ukungcoliswa kweTin Kusuka kwimithombo ekhanyayo esetshenziswa e-UV Lithography.

Ingonona

I-Argon ingenye igesi enhle, ngakho-ke ikhombisa ukusatshalaliswa okufanayo okuphansi njenge-nitrogen ne-helium. Kodwa-ke, amandla we-argon aphansi ama-ionization enza kube lusizo kuzinhlelo zokusebenza ze-semiconductor. Ngenxa yokukhululeka kwayo kalula kwe-ionization, i-argen ivame ukusetshenziswa njengegesi eyinhloko ye-plasma ye-etch kanye nokusabela kokukhishwa kwe-semiconductor. Ngaphezu kwalokhu, i-argen isetshenziswa futhi kuma-lacers e-excermers we-UV Lithography.

Kungani kuhlanzekile kubalulekile

Imvamisa, intuthuko ebukhwini be-semiconductor itholwe ngokulinganisa kobukhulu, futhi isizukulwane esisha sobuchwepheshe be-semiconductor sibonakaliswa ngosayizi wesici esincane. Lokhu kuveza izinzuzo eziningi: ama-transistors amaningi ngevolumu enikeziwe, ama-cursi athuthukisiwe, ukusetshenziswa kwamandla okuphansi kanye nokushintsha okusheshayo.

Kodwa-ke, njengoba usayizi obucayi uncipha, amadivaysi e-semiconductor akhuphuka ngokwengeziwe. Emhlabeni lapho isikhundla sama-athomu ngakunye, imibundu yokubekezelela enephutha iqinile kakhulu. Ngenxa yalokhu, izinqubo zesimanje ze-semiconductor zidinga amagesi enqubo ngokuhlanzeka okuphezulu kakhulu.

I-WOFLY iyibhizinisi eliphakeme kakhulu lobuchwepheshe ku-Excurity System Engineering: Uhlelo lwe-Electronic Special System, uhlelo lokuhlinzekwa kwamakhemikhali oluningi, i-System System System, Ukukhetha I-System, Ukukhetha Izemishini, Izakhi Zakho, Ukufakwa kanye Ukwakhiwa kwesiza sephrojekthi, ukuhlolwa kohlelo lonke, ukulungiswa kanye neminye imikhiqizo esekelayo ngendlela ehlanganisiwe.
