Kumzi mveliso we-semicondcuctor oqinileyo, egcina iimeko zemo engqongileyo ibalulekile kwiinkqubo ezisemgangathweni.Imolekyuli i-pitam pitaxy (MB), indlela ebaluleke kakhulu kwi-semicondcuction, izibonelelo ezibonakalayo kwinkqubela phambili kwitekhnoloji yokupholisa, ngakumbi ngokusetyenziswa kwe-nitrogen yolwelo kwayevacuum pipes yombhobho (i-VIP). Le bhlog iphonononga indima ebalulekileyo yeI-vipekwandiseni MbeIzicelo, ekugxininiseni ukusebenza kwawo kunye nokuthembeka.
Ukubaluleka kokupholisa i-mbe
Imolekyuli i-pitam pitaxy (MB)Yindlela elawulwa kakhulu yokubeka ii-atomic Lawers kwi-subrest, ibalulekile ekuveliseni izixhobo ze-semiconductor njengokuhanjiswa, ii-issers, kunye neeseli zelanga. Ukufezekisa ngokuchanekileyo okufunekayo kwi-MBE, ukugcina amaqondo obushushu aphantsi afanelekileyo. I-nitrogen yolwelo ihlala isetyenziselwa le njongo ngenxa yendawo yayo yokubila ephantsi kakhulu -196 ° C, iqinisekisa ukuba amantshontsho ahlala ehleli kwiqondo lokungasebenzi.
Indima ye-nitrogen yolwelo kwi-mbe
I-nitrogen yolwelo ibalulekile kwiinkqubo ze-MBE, ibonelela ngendlela engaguqukiyo eqinisekisa ukuba i-Plates i-Profuys ivela ngaphandle kokutshintsha okungafunekiyo. Oku kuzinza kubalulekile ekuveliseni izixhobo eziphezulu ze-semicondcuctor, njengoko amaqondo obushushu amancinci anokukhokelela kwiziphene okanye ukungangqinelaniyo kwi-Atomic Laters. Ukusetyenziswa kwe-nitrogen ye-nitrogen kunceda ukufezekisa iimeko ze-Ultra-figh ye-Ultra ephezulu efunekayo kwi-MBE, ethintele ungcoliseko kunye nokuqinisekisa ubunyulu bezinto.
IINGXAKI ZEMPHODI YOKUGQIBELA YOKUGQIBELA (VIP) kwi-MBE
Vacuum pipes yombhobho (i-VIP)Ngaba luphambili kuhambo olusebenzayo lwe-nitrogen yolwelo. Le mibhobho yenzelwe ngomaleko we-vacuum phakathi kweendonga ezimbini, ukunciphisa ubushushu obushushu kunye nokugcina ubushushu be-biyogenic ye-nitrogen ye-nitrogen njengoko ihamba kwindawo ye-MBE. Olu luyilo lunciphisa ilahleko ye-nitrogen yolwelo ngenxa yokuphuma kwamanzi, ukuqinisekisa ukubonelelwa okungagungqiyo kunye nokuthembeka kwi-MBICTUS.
Ukusebenza kakuhle kunye nokusebenza ngendleko
UkusebenzisaI-vipngaphakathiIzicelo ze-MBEinika izibonelelo ezininzi. Ilahleko yokutshiswa okuncitshisiweyo kuthetha ukuba i-nitrogen encinci ye-nitrogen iyafuneka, ukwehlisa iindleko zokusebenza kunye nokuphucula ukusebenza kakuhle. Ukongeza, ipropathi yokufakelwa kweI-vipIgalelo kwindawo ekhuselekileyo yokusebenza ngokunciphisa umngcipheko weflostbite kunye nezinye iingozi ezinxulumene nokuphatha izixhobo ze-crygenic.
Inkqubo yokuphucula inkqubo
I-vipiqinisekisa ukuba i-nitrogen ye-nitrogen ihlala inobushushu oguqukayo kuhambo lwayo ukuya kwiInkqubo ye-MBE. Olu nzo luzinzo lubaluleke kakhulu ekugcineni iimeko ezingqongqo eziyimfuneko kwimveliso ye-semicondcuctonuct. Ngokuthintela ukuguquguquka kobushushu,I-vipinceda ekuveliseni iyunifomu engaphezulu kunye ne-demiconductor ye-semiconductor, yandisa umgangatho ngokubanzi kunye nokusebenza kweemveliso zokugqibela.
Izixhobo ze-HL Crygenagec: Ekhokelela kwindlela ngeenkqubo ze-nitrogen ze-nitrogen ze-nitrogen
Izixhobo ze-HL Crygenic CO.Inkqubo yokujikeleza kwe-nitrogen yezothuthoOko kuqala kwitanki yogcino kunye nokuphela ngezixhobo ze-MBE. Le nkqubo iyayiqonda imisebenzi yothutho lwe-nitrogen ye-nitrogen, ukukhutshwa koxinzelelo, ukuncitshiswa koxinzelelo kunye nommiselo, ukukhutshwa kwe-nitrogen, kunye nokurisayikilisha. Yonke le nkqubo ijongwa yi-Cryogenic Elekos kwaye ilawulwa yi-PLC, ivumela utshintsho phakathi kweendlela zomsebenzi ezenzekelayo kunye neendlela zomsebenzi.
Okwangoku, le nkqubo isebenza kakuhle kwizixhobo ze-MBE kubavelisi abakhokelayo abanjenge-DCA, irayisi kunye ne-fermi. Ukufakwa kweIzixhobo ze-HL Crygenic'Inkqubo ephambili iqinisekisa ukubonelela nge-nitrogen yolwelo, esebenzayo yokuphucula ukusebenza kunye nokuzinza kweenkqubo ze-MBE.
Ukuqukumbela
Kwicandelo le-semiconductor, ngakumbi kwi Izicelo ze-MBE, ukusetyenziswa kwe-nitrogen yolwelo kwayevacuum pipes yombhobho (i-VIP)Ingathandeki.I-vipAyiphumi nje kuphela ukusebenza nokusebenza kweendleko zeenkqubo zokupholisa kodwa ikwaqinisekisa uzinzo kunye nokuchaneka okufunekayo kwi-semicondctor ephambili ye-semicondufuctory. Njengoko imfuno yezixhobo eziphambili ze-semicondctor iqhubeka nokukhula, intsha ngaphakathiI-vipItekhnoloji kunye neenkqubo eziphambili ezifana nezo ziphuhlisweIzixhobo ze-HL CrygenicUya kudlala indima ebalulekileyo ekufezekiseni iimfuno ezingqongqo zeshishini kunye nokuqhuba inkqubela phambili yexesha elizayo.
Ngokufumana izibonelelo zeI-vipkwayeIzixhobo ze-HL Crygenic'sinobunkunkqeleInkqubo yokujikeleza kwe-nitrogen yezothutho, Abavelisi be-semiconductor banokuyifumana ukungqungqa ngakumbi, ukusebenza ngokukuko, kunye nokhuseleko kwiinkqubo zabo ze-MB, ekugqibeleni bafaka isandla kuphuhliso lwezixhobo ze-elektroniki ezilandelayo.
