Kuyini ukugawula i-wafer?
ngumlawuli ngomhlaka-24-10-10
I-wafer kufanele idlule ezinguqukweni ezintathu ukuze ibe yi-chip yangempela ye-semiconductor: okokuqala, i-ingot efana nebhulokhi inqunywa ibe ama-wafer; enqubweni yesibili, ama-transistors aqoshwa ngaphambili kwe-wafer enqubweni yangaphambilini; ekugcineni, ukupakishwa kwenziwa, okungukuthi, ngenqubo yokusika...

Ukusetshenziswa kwe-silicon carbide ceramics ensimini ye-semiconductor
ngumlawuli ngomhlaka-24-10-10
Izinto ezikhethwayo zezingxenye ezinembile zemishini ye-photolithography Ensimini ye-semiconductor, izinto ze-silicon carbide ceramic zisetshenziswa kakhulu emishinini ebalulekile yokukhiqiza isekethe ehlanganisiwe, njengetafula lokusebenza le-silicon carbide, imigqa yokuqondisa, izibonisi, i-ceramic suction chuck, izingalo,...

Yiziphi izinhlelo eziyisithupha zesithando somlilo esisodwa sekristalu
ngumlawuli ngomhlaka-24-09-23
Isithando somlilo sekristalu esisodwa siwumshini osebenzisa i-graphite heater ukuncibilikisa izinto ze-polycrystalline silicon endaweni engenagesi (i-argon) futhi usebenzisa indlela yeCzochralski ukukhulisa amakristalu angahlukanisiwe. Ngokuyinhloko sakhiwe yizinhlelo ezilandelayo: Oomatshini...

Kungani sidinga i-graphite ensimini yokushisa yesithando sekristalu esisodwa
ngumlawuli ngomhlaka-24-09-23
Uhlelo lokushisa lwesithando sekristalu elilodwa eliqondile lubizwa nangokuthi insimu yokushisa. Umsebenzi wohlelo lwensimu yokushisa ye-graphite ubhekisela ohlelweni lonke lokuncibilikisa izinto ze-silicon nokugcina ukukhula kwekristalu elilodwa ekushiseni okuthile. Kalula nje, kuyi-grap ephelele...

Izinhlobo eziningana zezinqubo zokusika i-wafer ye-semiconductor yamandla
ngu-admin ngomhlaka-24-09-20
Ukusikwa kwe-wafer kungenye yezixhumanisi ezibalulekile ekukhiqizweni kwe-semiconductor yamandla. Lesi sinyathelo senzelwe ukuhlukanisa ngokunembile amasekethe noma ama-chips ahlanganisiwe ngamanye kuma-wafer e-semiconductor. Isihluthulelo sokusikwa kwe-wafer ukukwazi ukuhlukanisa ama-chips ngamanye ngenkathi kuqinisekiswa ukuthi isakhiwo esibucayi...

Inqubo ye-BCD
ngumlawuli ngomhlaka-24-09-18
Iyini inqubo ye-BCD? Inqubo ye-BCD iwubuchwepheshe benqubo ehlanganisiwe ene-chip eyodwa eyethulwa okokuqala yi-ST ngo-1986. Lobu buchwepheshe bungenza amadivayisi e-bipolar, CMOS kanye ne-DMOS ku-chip efanayo. Ukubukeka kwayo kunciphisa kakhulu indawo ye-chip. Kungashiwo ukuthi inqubo ye-BCD isebenzisa ngokugcwele...

Siyakwamukela kuwebhusayithi yethu ukuze uthole ulwazi lomkhiqizo kanye nokubonisana. Iwebhusayithi yethu: https://www.vet-china.com/ Njengoba izinqubo zokukhiqiza ze-semiconductor ziqhubeka nokwenza intuthuko, isitatimende esidumile esibizwa ngokuthi "uMthetho kaMoore" besilokhu sisakazwa embonini. Besi...

Inqubo yokuhlela amaphethini e-semiconductor
ngu-admin ngomhlaka-24-09-10
Ukucwilisa okumanzi kwasekuqaleni kwakhuthaza ukuthuthukiswa kwezinqubo zokuhlanza noma zokulahla umlotha. Namuhla, ukucwilisa okomile kusetshenziswa i-plasma sekuyindlela evamile yokucwilisa. I-Plasma yakhiwa ama-electron, ama-cation nama-radicals. Amandla asetshenziswa ku-plasma abangela ama-electron angaphandle...
