Faahfaahinta Badeecada

Calaamadaha Alaabta

Tamarta VETSaxanka Garaafiga ee Silikoon Carbide, Saxanka, iyo Daboolka waxaa loo qaabeeyey inuu bixiyo waxqabad heer sare ah, isagoo bixinaya hawlgal la isku halleyn karo oo joogto ah inta lagu jiro isticmaalka dheeraadka ah, taasoo ka dhigaysa doorasho muhiim ah oo loogu talagalay codsiyada farsamaynta wafer-ka ee warshadaha semiconductor-ka.Saxanka Garaafiga ee Silicon CarbideWaxay leedahay iska caabbin kulayl oo aad u fiican, isku mid ahaanshaha kulaylka oo sarreeya, iyo xasillooni kiimiko oo heer sare ah, gaar ahaan xaaladaha heerkulka sare. Dhismaheeda saafiga ah, oo ay weheliso iska caabbinta nabaad-guurka oo horumarsan, ayaa ka dhigaya mid aan lagama maarmaan u ah deegaannada baahida badan leh sidaSumeeyayaasha MOCVD.

Astaamaha Muhiimka ah ee Saxanka Garaafiga ee Dahaadhka Silicon Carbide, Saxanka, iyo Daboolka

1. Iska caabinta oksaydhaynta Heerkulka Sare:Waxay u adkaysataa heerkulka ilaa 1700℃, taasoo u oggolaanaysa inay si kalsooni leh u shaqeyso xaaladaha daran.

2. Nadiifin Sare iyo Midayn Kulayl:Nadiifnimo joogto ah oo heer sare ah iyo xitaa qaybinta kulaylka ayaa muhiim u ah codsiyada MOCVD.

3. Iska caabinta Daxalka ee Gaarka ah:Waxay u adkaysataa asiidhyada, alkalis, cusbada, iyo walxaha kala duwan ee dabiiciga ah, iyadoo hubinaysa xasillooni muddo dheer ah deegaanno kala duwan.

4. Adkayn Sare iyo Dusha Sare ee Is haysta:Waxay leedahay dusha cufan oo leh walxo yaryar, taasoo hagaajinaysa adkeysiga guud iyo iska caabbinta xirashada.

5. Cimriga Adeegga ee La Dheereeyay:Waxaa loo sameeyay cimri dheer, iyadoo si ka wanaagsan sidii caadiga ahayd loo sameeyaySusceptors-ka graphite ee silikoon-ka ah ee lagu dahaadhay carbidejawiyada habaynta semiconductor-ka ee adag.
