Iindaba-Iprojekthi ye-Chip Mbe igqityiwe kule minyaka idlulileyo

Itekhnoloji

Imolekyuli ye-molecrour pitaxy, okanye i-mbe, yindlela entsha yokukhula kweefilimu eziphezulu eziphezulu zeekristale kumakristali. Kwiimeko ze-ertra-figuum ephezulu, ngesitovu sokufudumeza sixhotyisiwe nazo zonke iintlobo zezinto ezifunekayo kwaye zivelise i-steam, ngemingxunya eyenziwe emva komgangatho ofanelekileyo we-amomic okanye i-molecroule ye-substrate ye-crystal, ukulawula i-molecroule ye-crystal, ukulawula i-molecrour beam Ukuskena kobungakanani kwangaxeshanye, kunokwenza iimolekyuli okanye iiatom kwi-crystal yokulungelelanisa ukwenza ifilimu ecekeceke yokuqina "kukukhula".

Ukusetyenziswa kwesiqhelo kwezixhobo ze-MBE, ukucoceka okuphakamileyo, uxinzelelo oluphantsi kunye ne-witrogen ye-Ultra ecocekileyo kufuneka iqhubekeke ngokuqhubekayo igumbi lokupholisa kwezixhobo. Ngokubanzi, itanki elibonelela nge-nitrogen yolwelo linengcinezelo yemveliso phakathi kwe-0.3MPA kunye ne-0.8MPAID nitrogen kwi-1,liquid nitrogen kwi-nitrogen ngexesha lokuhamba kwepayipile. Nje ukuba i-nitrogen yolwelo enomlinganiselo wamanzi wegesi malunga ne-1: 700 ihluthwe ngombhobho, iya kuhlala isixa esikhulu sendawo yokuhamba nge-nitrogen kwaye inciphise ukuhamba kwe-nitrogen yenitrogen. Ukongeza, kwitanki yokugcina i-nitrogen ye-nitrogen, kusenokwenzeka ukuba kunokwenzeka ukuba ubekeke. Kwipipili ye-nitrogen ye-nitrogen, ubukho bomoya omanzi buya kukhokelela kwisizukulwane somkhenkce. Ukuba ezi zinto zingcolileyo zikhutshiwe kwizixhobo, ziya kubangela umonakalo ongalindelekanga kwizixhobo.

Ke ngoko, i-nitrogen ye-nitrogen kwitanki yokugcina engaphandle ithuthwa kwiworkshop ye-MBE ngokusebenza okuphezulu, uzinzo, i-nitrogen, i-itrogen, i-itrogen, i-iiyure ezingama-24 ingaphazamiseki, inkqubo yokulawula ezothutho yile Imveliso efanelekileyo.

Ukutshatisa izixhobo ze-MBE

Ukusukela ngo-2005, izixhobo ze-HL Cry Gygenic (HL CHECE) sele ifanelekile kwaye iphucule le nkqubo kwaye isebenzisane nabavelisi be-MBE yamanye amazwe. Abavelisi besixhobo se-MBE, kubandakanya i-DCA, i-reber, ibe nobudlelwane obunentsebenziswano nenkampani yethu. Abavelisi besixhobo se-MBE, kubandakanya i-DCA kunye ne-reber, basebenzise inani elikhulu leeprojekthi.

I-Riber SA nguMboneleli oBalulekileyo weHlabathi weMolecroulaxy Seam Eptaxy (MBE) kunye neenkonzo ezinxulumene nophando lwezixhobo ze-semiconductor kunye nezicelo zemveliso. Isixhobo seRiber Mbe sinokuthi ifake iingqimba zamatye anqabileyo zezinto ezikwinqanaba, kulawulo oluphezulu kakhulu. Izixhobo ze-vacuum ze-HL Cry Griogenic Izixhobo (Hl Cryso) zixhotywe nge-riber yodwa ezona zixhobo zikhulu yi-riber 6000 kunye neyona incinci kwaye ithathelwe ingqalelo ngabathengi.

I-DCA ye-oxide yehlabathi. Ukusukela ngo-1993, ukuphuculwa okucwangcisiweyo kweendlela zobuchule be-oxidation, ukufudumeza okwenziwe nge-antioxidant kunye nemithombo ye-antioxidant yenziwa. Ngesi sizathu, iilebhu ezininzi ezikhokelayo zikhethe itekhnoloji ye-Dca oxide. I-Commaite semiconductor Mbe Systems zisetyenziswa kwihlabathi liphela. Inkqubo ye-vJ ijikeleza i-nitrogen yesixhobo se-HL Crygenagesic (HL CHWO) kunye nezixhobo ze-MBE zeemodeli ezininzi ze-DCA zinamava ahambelana neeprojekthi ezininzi, ezifana nemodeli ye-P600, i-SGC800, i-SGC800 njl njl.
