Embonini ye-semiconductor esheshayo, ukugcina izimo zemvelo ezinembile kubalulekile ezinqubweni zokukhiqiza ezisezingeni eliphezulu.I-Molecular Beam Epitaxy (MBE), inqubo ebalulekile ekwakhiweni kwe-semiconductor, izuza kakhulu ekuthuthukisweni kobuchwepheshe bokupholisa, ikakhulukazi ngokusebenzisa i-nitrogen ewuketshezi kanyeamapayipi afakwe i-vacuum cleaner (VIP)Le bhulogi ihlola indima ebalulekile yeI-VIPekuthuthukiseni I-MBEizinhlelo zokusebenza, kugcizelelwa ukusebenza kahle nokuthembeka kwayo.
Ukubaluleka Kokupholisa ku-MBE
I-Molecular Beam Epitaxy (MBE)kuyindlela elawulwa kakhulu yokufaka izendlalelo zama-athomu ku-substrate, ebalulekile ekukhiqizeni amadivayisi e-semiconductor afana nama-transistors, ama-laser, namaseli elanga. Ukuze kufezwe ukunemba okuphezulu okudingekayo ku-MBE, ukugcina amazinga okushisa aphansi azinzile kubalulekile. I-nitrogen ewuketshezi ivame ukusetshenziselwa le njongo ngenxa yezinga layo eliphansi kakhulu lokubila elingu--196°C, okuqinisekisa ukuthi ama-substrate ahlala emazingeni okushisa adingekayo ngesikhathi senqubo yokufaka.
Indima Ye-Nitrogen Ewuketshezi Ku-MBE
I-nitrogen ewuketshezi ibalulekile ezinqubweni ze-MBE, ihlinzeka ngendlela yokupholisa eqhubekayo eqinisekisa ukuthi ukufakwa kwenzeka ngaphandle kokushintshashintsha kokushisa okungafuneki. Lokhu kuzinza kubalulekile ekukhiqizeni izinto ze-semiconductor ezisezingeni eliphezulu, njengoba ngisho nokushintshashintsha okuncane kokushisa kungaholela emaphutheni noma ekungahambelani kwezingqimba zama-athomu. Ukusetshenziswa kwe-nitrogen ewuketshezi kusiza ukufeza izimo ze-vacuum eziphakeme kakhulu ezidingekayo ze-MBE, ukuvimbela ukungcola nokuqinisekisa ubumsulwa bezinto.
Izinzuzo Zamapayipi Afakwe I-Vacuum Insulated (VIP) ku-MBE
Amapayipi afakwe ugesi (i-VIP)ziyintuthuko ekuthuthweni okuphumelelayo kwe-nitrogen ewuketshezi. Lawa mapayipi aklanywe ngesendlalelo se-vacuum phakathi kwezindonga ezimbili, okunciphisa kakhulu ukudluliselwa kokushisa futhi kugcina izinga lokushisa le-nitrogen ewuketshezi lihlala likhona njengoba lisuka endaweni yokugcina izinto liye ohlelweni lwe-MBE. Lo mklamo unciphisa ukulahleka kwe-nitrogen ewuketshezi ngenxa yokuhwamuka, okuqinisekisa ukutholakala okuqhubekayo nokuthembekile kwemishini ye-MBE.
Ukusebenza Kahle Nokusebenza Kahle Ngezindleko
UkusebenzisaI-VIPkuIzinhlelo zokusebenza ze-MBEinikeza izinzuzo eziningana. Ukulahlekelwa ukushisa okuncishisiwe kusho ukuthi kudingeka i-nitrogen encane ewuketshezi, kunciphisa izindleko zokusebenza kanye nokuthuthukisa ukusebenza kahle. Ngaphezu kwalokho, izici zokuvikela ukushisa zeI-VIPkunegalelo endaweni yokusebenza ephephile ngokunciphisa ingozi yokubanda kanye nezinye izingozi ezihlobene nokuphatha izinto ezibangela ukucasuka.
Ukuqina Kwenqubo Okuthuthukisiwe
I-VIPiqinisekisa ukuthi i-nitrogen ewuketshezi ihlala ekushiseni okulinganayo kulo lonke uhambo lwayo oluya e-Uhlelo lwe-MBELokhu kuzinza kubaluleke kakhulu ekugcineni izimo eziqinile ezidingekayo ekukhiqizweni kwe-semiconductor okunembe kakhulu. Ngokuvimbela ukuguquguquka kwezinga lokushisa,I-VIPkusiza ukukhiqiza izendlalelo eziningi ze-semiconductor ezifanayo nezingenamaphutha, okuthuthukisa ikhwalithi iyonke kanye nokusebenza kwemikhiqizo yokugcina.
Imishini ye-HL Cryogenic: Ukuhola Indlela Ngezinhlelo Zokujikeleza Kwe-Nitrogen Ezithuthukisiwe
I-HL Cryogenic Equipment Co., Ltd ithuthukise futhi yacwaninga ubuchwepheshe obusezingeni eliphezuluUhlelo Lokujikeleza Kwe-Nitrogen Yoketshezioluqala ethangini lokugcina bese luphela ngemishini ye-MBE. Lolu hlelo lufeza imisebenzi yokuthuthwa kwe-nitrogen ewuketshezi, ukukhishwa kokungcola, ukunciphisa ingcindezi kanye nokulawula, ukukhishwa kwe-nitrogen, kanye nokusetshenziswa kabusha. Yonke inqubo iqashwa yizinzwa ze-cryogenic futhi ilawulwa yi-PLC, okuvumela ukushintshana phakathi kwezindlela zokusebenza okuzenzakalelayo kanye nezindlela zokusebenza ngesandla.
Njengamanje, lolu hlelo lusebenzisa imishini ye-MBE ngokuzinzile evela kubakhiqizi abaphambili njenge-DCA, i-RIBER, kanye ne-FERMI.Imishini ye-HL Cryogenic'Uhlelo oluthuthukisiwe luqinisekisa ukuhlinzekwa okuthembekile nokuphumelelayo kwe-nitrogen ewuketshezi, okuthuthukisa ukusebenza kanye nokuzinza kwezinqubo ze-MBE.
Isiphetho
Embonini ye-semiconductor, ikakhulukazi Izinhlelo zokusebenza ze-MBEukusetshenziswa kwe-nitrogen ewuketshezi kanyeamapayipi afakwe i-vacuum cleaner (VIP)kuyinto ebaluleke kakhulu.I-VIPakugcini nje ngokuthuthukisa ukusebenza kahle kanye nokusebenza kahle kwezinhlelo zokupholisa kodwa futhi kuqinisekisa ukuzinza nokunemba okudingekayo ekwenziweni kwe-semiconductor esezingeni eliphezulu. Njengoba isidingo samadivayisi e-semiconductor athuthukile siqhubeka nokukhula, ukusungula izinto ezintsha kuI-VIPubuchwepheshe kanye nezinhlelo ezithuthukisiwe njengalezo ezakhiwe yi-Imishini ye-HL Cryogenicizodlala indima ebalulekile ekuhlangabezaneni nezidingo eziqinile zemboni kanye nokuqhuba intuthuko yesikhathi esizayo.
Ngokusebenzisa izinzuzo zeI-VIPfuthiImishini ye-HL Cryogenic'sokuthuthukisiweUhlelo Lokujikeleza Kwe-Nitrogen Yoketshezi, abakhiqizi be-semiconductor bangafinyelela ukuvumelana okukhulu, ukusebenza kahle, kanye nokuphepha ezinqubweni zabo ze-MBE, ekugcineni banikele ekuthuthukisweni kwamadivayisi kagesi esizukulwane esilandelayo.
