Embonini ye-semiconductor esheshayo, ukugcina izimo zemvelo ezinembile kubalulekile ezinqubweni zokukhiqiza ezisezingeni eliphezulu.I-Molecular Beam Epitaxy (MBE), indlela ebaluleke kakhulu ekwenziweni kwe-semiconductor, izuza kakhulu ekuthuthukisweni kobuchwepheshe bokupholisa, ikakhulukazi ngokusebenzisa i-nitrogen ewuketshezi kanyevacuum insulated amapayipi (VIP). Le bhulogi ihlola indima ebalulekile yeI-VIPekuthuthukiseni MBEizinhlelo zokusebenza, ezigcizelela ukusebenza kahle nokuthembeka kwayo.
Ukubaluleka Kokupholisa ku-MBE
I-Molecular Beam Epitaxy (MBE)iyindlela elawulwa kakhulu yokufaka izendlalelo ze-athomu ku-substrate, ebalulekile ekukhiqizeni amadivaysi e-semiconductor afana nama-transistors, ama-laser, namaseli elanga. Ukufeza ukunemba okuphezulu okudingekayo ku-MBE, ukugcina izinga lokushisa eliphansi elizinzile kubalulekile. I-nitrogen ewuketshezi ivamise ukusetshenziselwa le njongo ngenxa yokubilisa kwayo okuphansi kakhulu -196°C, okuqinisekisa ukuthi ama-substrates ahlala emazingeni okushisa adingekayo phakathi nenqubo yokubeka.
Iqhaza Le-Liquid Nitrogen ku-MBE
I-nitrogen ewuketshezi ibalulekile ezinqubweni ze-MBE, ihlinzeka ngendlela yokupholisa engaguquki eqinisekisa ukuthi ukufakwa kwenzeka ngaphandle kokuguquguquka okungafuneki kokushisa. Lokhu kuzinza kubalulekile ekukhiqizeni izinto zezinga eliphezulu ze-semiconductor, njengoba ngisho nokwehluka okuncane kwezinga lokushisa kungaholela ekulimaleni noma ekushintshaneni kwezendlalelo ze-athomu. Ukusetshenziswa kwe-nitrogen ewuketshezi kusiza ukufeza izimo ze-vacuum eziphezulu kakhulu ezidingekayo ku-MBE, ukuvimbela ukungcola nokuqinisekisa ukuhlanzeka kwezinto.
Izinzuzo ze-Vacuum Insulated Pipes (VIP) ku-MBE
Vacuum insulated amapayipi (VIP)ziyimpumelelo ekuthuthweni kwe-nitrogen ewuketshezi. Lawa mapayipi aklanywe nge-vacuum layer phakathi kwezindonga ezimbili, enciphisa ngokuphawulekayo ukudluliswa kokushisa nokugcina izinga lokushisa le-cryogenic le-nitrogen ewuketshezi njengoba lihamba lisuka kwisitoreji liye ohlelweni lwe-MBE. Lo mklamo unciphisa ukulahleka kwe-nitrogen ewuketshezi ngenxa yokuhwamuka, iqinisekisa ukutholakala okuzinzile nokuthembekile kumshini we-MBE.
Ukusebenza kahle kanye Nezindleko-Ngempumelelo
UkusebenzisaI-VIPphakathiMBE iziceloinikeza izinzuzo eziningana. Ukulahlekelwa ukushisa okuncishisiwe kusho i-nitrogen ewuketshezi encane edingekayo, ukwehlisa izindleko zokusebenza kanye nokuthuthukisa ukusebenza kahle. Ukwengeza, izakhiwo ze-insulation zeI-VIPukufaka isandla endaweni ephephile yokusebenza ngokunciphisa ubungozi besithwathwa nezinye izingozi ezihlobene nokuphatha izinto ze-cryogenic.
Ukuzinza Kwenqubo Okuthuthukisiwe
I-VIPiqinisekisa ukuthi i-nitrogen ewuketshezi ihlala ezingeni lokushisa elingashintshi phakathi nohambo lwayo lokuya e-Uhlelo lwe-MBE. Lokhu kuzinza kubaluleke kakhulu ekugcineni izimo eziqinile ezidingekayo ekukhiqizeni i-semiconductor enembayo ephezulu. Ngokuvimbela ukushintsha kwezinga lokushisa,I-VIPisiza ukukhiqiza izendlalelo eziningi ezifanayo nezingenasici ze-semiconductor, ithuthukisa ikhwalithi iyonke nokusebenza kwemikhiqizo yokugcina.
I-HL Cryogenic Equipment: Ehola Indlela Nge-Advanced Liquid Nitrogen Circulation Systems
I-HL Cryogenic Equipment Co., Ltd ithuthukise futhi yenza ucwaningo olusezingeni eliphezuluI-Liquid Nitrogen Transport Circulation Systemeqala ethangini lokugcina futhi iphele ngemishini ye-MBE. Lolu hlelo lubona imisebenzi yokuthuthwa kwe-nitrogen ewuketshezi, ukukhipha ukungcola, ukuncishiswa kwengcindezi nokulawula, ukukhishwa kwe-nitrogen, nokugaywa kabusha. Yonke le nqubo igadwe yizinzwa ze-cryogenic futhi ilawulwa yi-PLC, ivumela ukushintshwa phakathi kwezindlela zokuzenzakalela nezamabhukwana.
Njengamanje, lolu hlelo lusebenza ngokuzinzile kwemishini ye-MBE evela kubakhiqizi abahamba phambili abanjenge-DCA, i-RIBER, ne-FERMI. Ukufakwa kweI-HL Cryogenic Equipment's uhlelo oluthuthukisiwe luqinisekisa ukunikezwa okuthembekile nokusebenzayo kwe-nitrogen eyi-liquid, ithuthukisa ngokwengeziwe ukusebenza nokuzinza kwezinqubo ze-MBE.
Isiphetho
Embonini ye-semiconductor, ikakhulukazi ku MBE izicelo, ukusetshenziswa kwe-nitrogen ewuketshezi kanyevacuum insulated amapayipi (VIP)ibalulekile.I-VIPakugcini nje ngokuthuthukisa ukusebenza kahle kanye nokuphumelela kwezindleko zezinhlelo zokupholisa kodwa futhi kuqinisekisa ukuzinza nokunemba okudingekayo ekwenziweni kwekhwalithi ephezulu ye-semiconductor. Njengoba isidingo samadivayisi we-semiconductor athuthukisiwe siqhubeka nokukhula, ukusungulwa okushaI-VIPubuchwepheshe kanye nezinhlelo ezithuthukile ezifana nalezo ezithuthukiswe nguI-HL Cryogenic Equipmentizodlala indima ebalulekile ekuhlangabezaneni nezidingo eziqinile zemboni kanye nokuqhuba intuthuko yesikhathi esizayo.
Ngokusebenzisa izinzuzo zeI-VIPfuthiI-HL Cryogenic Equipment'seyinkimbinkimbiI-Liquid Nitrogen Transport Circulation System, abakhiqizi be-semiconductor bangakwazi ukufeza ukungaguquguquki okukhulu, ukusebenza kahle, nokuphepha ezinqubweni zabo ze-MBE, ekugcineni kube negalelo ekuthuthukisweni kwamadivayisi kagesi esizukulwane esilandelayo.
