Kwishishini le-semiconductor elikhawulezayo, ukugcina iimeko ezichanekileyo zokusingqongileyo kubalulekile kwiinkqubo zokwenziwa komgangatho ophezulu.I-Molecular Beam Epitaxy (MBE), ubuchule obubalulekileyo kulwakhiwo lwe-semiconductor, luzuza kakhulu kwinkqubela phambili yetekhnoloji yokupholisa, ngakumbi ngokusetyenziswa kwenitrogen engamanzi kunyeimibhobho egqunywe ngevacuum (VIP). Le blog iphonononga indima ebalulekileyoVIPekuphuculeni MBEizicelo, igxininisa ukusebenza kakuhle nokuthembeka kwayo.
Ukubaluleka kokupholisa kwi-MBE
I-Molecular Beam Epitaxy (MBE)yindlela elawulwa kakhulu yokubeka iileya zeathom kwi-substrate, ibalulekile ekuveliseni izixhobo ze-semiconductor ezifana neetransistors, iilaser, kunye neeseli zelanga. Ukufezekisa ukuchaneka okuphezulu okufunekayo kwi-MBE, ukugcina amaqondo okushisa aphantsi okuzinzileyo kubalulekile. Initrogen elulwelo isoloko isetyenziselwa le njongo ngenxa yeqondo lokubila eliphantsi kakhulu elingu-196°C, iqinisekisa ukuba isubstrates zihlala kumaqondo obushushu ayimfuneko ngexesha lenkqubo yokugalelwa.
Indima yeNitrogen yolwelo kwi-MBE
Initrogen yolwelo iyimfuneko kwiinkqubo ze-MBE, ibonelela ngendlela yokupholisa engaguqukiyo eqinisekisa ukuba ukubekwa kwenzeka ngaphandle kokuguquguquka okungafunekiyo kwe-thermal. Olu uzinzo lubalulekile ekuveliseni izinto ezikumgangatho ophezulu we-semiconductor, njengoko nokwahluka okuncinci kwamaqondo obushushu kunokukhokelela kwiziphene okanye ukungangqinelani kumaleko eathom. Ukusetyenziswa kwe-nitrogen engamanzi kunceda ukufezekisa iimeko ze-vacuum ze-ultra-high ezifunekayo kwi-MBE, ukukhusela ukungcola kunye nokuqinisekisa ukucoceka kwezinto.
Izinto ezilungileyo zeMibhobho yeVacuum Insulated (VIP) kwi-MBE
Imibhobho egqunywe ngevacuum (VIP)ziyimpumelelo kuthutho olusebenzayo lwenitrogen engamanzi. Le mibhobho ziyilelwe kunye umaleko vacuum phakathi kweendonga ezimbini, ukunciphisa ngokuphawulekayo transfer ubushushu kunye nokugcina ubushushu cryogenic of ulwelo nitrogen njengoko ihamba ukusuka yokugcina ukuya kwinkqubo MBE. Olu yilo lunciphisa ilahleko yenitrogen engamanzi ngenxa yokumka komphunga, iqinisekisa unikezelo oluzinzileyo noluthembekileyo kwizixhobo zeMBE.
Ukusebenza ngokuSebenzayo kunye nokuSebenza kweendleko
UkusebenzisaVIPkwiizicelo MBEinikeza iingenelo ezininzi. Ilahleko yobushushu encitshisiweyo ithetha ukuba i-nitrogen engamanzi encinci iyafuneka, ukuthoba iindleko zokusebenza kunye nokuphucula ukusebenza kakuhle. Ukongeza, iipropathi ze-insulation zeVIPigalelo kwindawo ekhuselekileyo yokusebenza ngokunciphisa umngcipheko we-frostbite kunye nezinye iingozi ezinxulumene nokuphatha izinto ze-cryogenic.
Uzinzo lwenkqubo oluphuculweyo
VIPiqinisekisa ukuba ulwelo nitrogen uhlala kubushushu obuhambelanayo kulo lonke uhambo lwayo ukuyaInkqubo ye-MBE. Oku kuzinza kubaluleke kakhulu ekugcineni iimeko ezingqongqo eziyimfuneko kwimveliso ye-semiconductor echanekileyo. Ngokuthintela ukuguquguquka kobushushu,VIPinceda ukuvelisa iileya ze-semiconductor ezifanayo kunye nezingenasiphako, ukuphucula umgangatho kunye nokusebenza kweemveliso zokugqibela.
