Izindlela ezintathu ezinkulu zokukhula kwekristalu ye-SiC
Njengoba kuboniswe ku-Fig. 3, kunezindlela ezintathu ezivelele ezihlose ukunikeza i-SiC single crystal ngekhwalithi ephezulu kanye nokusebenza kahle: i-liquid phase epitaxy (LPE), i-physical vapor transport (PVT), kanye ne-high-temperature chemical vapor deposition (HTCVD). I-PVT inqubo esungulwe kahle yokukhiqiza i-SiC sin...Funda kabanzi -
Isingeniso esifushane se-semiconductor yesizukulwane sesithathu i-GaN kanye nobuchwepheshe be-epitaxial obuhlobene
1. Ama-semiconductor esizukulwane sesithathu Ubuchwepheshe be-semiconductor besizukulwane sokuqala bathuthukiswa ngokusekelwe ezintweni ze-semiconductor ezifana ne-Si ne-Ge. Buyisisekelo sezinto ezibonakalayo sokuthuthukiswa kwama-transistors kanye nobuchwepheshe besekethe ehlanganisiwe. Izinto ze-semiconductor zesizukulwane sokuqala zabeka...Funda kabanzi -
Amabhiliyoni angu-23.5, i-super unicorn kaSuzhou iya e-IPO
Ngemva kweminyaka engu-9 yokuhweba, i-Innoscience iqoqe imali engaphezu kwezigidigidi eziyisithupha zama-yuan, futhi inani layo lifinyelele kuma-yuan ayizigidigidi ezingama-23.5. Uhlu lwabatshalizimali lude njengezinkampani eziningi: i-Fukun Venture Capital, i-Dongfang State-owned Assets, i-Suzhou Zhanyi, i-Wujian...Funda kabanzi -
Imikhiqizo eboshwe nge-tantalum carbide ithuthukisa kanjani ukumelana nokugqwala kwezinto?
I-Tantalum carbide coating iwubuchwepheshe bokwelapha ubuso obusetshenziswa kakhulu obungathuthukisa kakhulu ukumelana nokugqwala kwezinto. I-Tantalum carbide coating inganamatheliswa ebusweni be-substrate ngezindlela ezahlukene zokulungiselela, njengokufakwa komphunga wamakhemikhali, i-physica...Funda kabanzi -

Ucwaningo lokulingisa ngezinombolo ngomphumela we-graphite enezimbobo ekukhuleni kwekristalu ye-silicon carbide
Inqubo eyisisekelo yokukhula kwekristalu ye-SiC ihlukaniswe ngokufakwa kwe-sublimation kanye nokubola kwezinto zokusetshenziswa ekushiseni okuphezulu, ukuthuthwa kwezinto zesigaba segesi ngaphansi kwesenzo se-gradient yokushisa, kanye nokukhula kabusha kwe-gas phase substances kukristalu yembewu. Ngokusekelwe kulokhu,...Funda kabanzi -
Izinhlobo zeGraphite Ekhethekile
I-graphite ekhethekile iwubumsulwa obuphezulu, ukuminyana okuphezulu kanye nezinto ze-graphite ezinamandla aphezulu futhi inokumelana okuhle kakhulu nokugqwala, ukuqina kokushisa okuphezulu kanye nokuqhuba kahle kukagesi. Yenziwe nge-graphite yemvelo noma yokwenziwa ngemva kokwelashwa kokushisa okuphezulu kanye nokucutshungulwa kokucindezela okuphezulu...Funda kabanzi -
Ukuhlaziywa kwemishini yokufaka ifilimu encane - izimiso kanye nokusetshenziswa kwemishini ye-PECVD/LPCVD/ALD
Ukufakwa kwefilimu encane kuwukumboza ungqimba lwefilimu ezintweni eziyinhloko ze-semiconductor. Le filimu ingenziwa ngezinto ezahlukahlukene, njenge-insulating compound silicon dioxide, i-semiconductor polysilicon, ithusi lensimbi, njll. Imishini esetshenziselwa ukumboza ibizwa ngokuthi i-thin film deposition...Funda kabanzi -
Izinto ezibalulekile ezinquma ikhwalithi yokukhula kwe-silicon ye-monocrystalline - insimu yokushisa
Inqubo yokukhula kwe-silicon e-monocrystalline yenziwa ngokuphelele ensimini yokushisa. Insimu enhle yokushisa ikhuthaza ukuthuthukisa ikhwalithi yamakristalu futhi inokusebenza kahle kwe-crystallization okuphezulu. Ukwakheka kwensimu yokushisa kunquma kakhulu izinguquko kuma-gradient okushisa...Funda kabanzi
