4H-semi HPSI 2inch SiC substrate wafer wafer Wax soo saarka heerka cilmi baarista

4H-semi HPSI 2inch SiC substrate wafer Wax-soosaarka heerka cilmi baarista ee heerka hoose ee muuqaalka leh

Sharaxaad Gaaban:

2inch silicon carbide wafer substrate crystal waa walax wax qabad sare leh oo leh astaamo jireed iyo kiimiko oo aad u wanaagsan. Waxay ka samaysan tahay walxo silikoon carbide ah oo nadiif ah oo nadiif ah oo leh walxo kuleyl ah oo aad u fiican, xasilloonida farsamada iyo iska caabinta heerkulka sare. Waad ku mahadsan tahay habka diyaarinta saxda ah ee saxda ah iyo qalabka tayada sare leh, jajabkani waa mid ka mid ah qalabka la doorbido ee loogu talagalay diyaarinta qalabka elektaroonigga ah ee waxqabadka sare leh ee dhinacyo badan.

Substrate-ka silikoon carbide substrate-ka-dahaaran ee SiC

Substrate-ka Silicon carbide waxaa inta badan loo kala qaybiyaa nooca korantada iyo nus-insulating, substrate-ka silikoon carbide ee nooca n-nooca waxaa inta badan loo isticmaalaa LED-ka-ku-saleysan Epitaxial iyo aaladaha kale ee optoelectronic, aaladaha korantada ee SiC-ku-saleysan, iwm, iyo semi- Dahaarka SiC silikoon carbide substrate waxaa inta badan loo isticmaalaa soo saarista epitaxial ee aaladaha soo noqnoqda raadiyaha tamarta sare leh ee GaN. Intaa waxaa dheer ee nadiifinta-sare ee semi-dahaarka HPSI iyo SI semi-dahaarka waa ka duwan yahay,-nadiifinta sare-nadiifinta-xakamaynta-sare ee 3.5 * 1013 ~ 8 * 1015/cm3 kala duwan, oo leh dhaqdhaqaaqa elektarooniga sare; Semi-insulation waa maaddooyin iska caabin ah oo sarreeya, iska caabintu aad bay u sarraysaa, guud ahaan waxaa loo isticmaalaa substrates-ka aaladaha mikrowave-ka, aan shaqaynayn.

Waferka substrate-ka ah ee Silicon Carbide-dahadhka ah ee SiC wafer

Qaab dhismeedka kristal ee SiC wuxuu go'aamiyaa jirkiisa, marka loo eego Si iyo GaAs, SiC waxay u leedahay sifooyinka jirka; Baaxadda band ee mamnuuca ah waa mid weyn, oo ku dhow 3 jeer ka Si, si loo hubiyo in qalabku ku shaqeeyo heerkul sare oo hoos yimaada kalsoonida muddada-dheer; xoogga beerta burburku waa mid sare, waa 1O jeer ka mid ah Si, si loo hubiyo in awoodda danab qalabka, hagaajin qiimaha danab qalabka; heerka korantada korantada waa weyn yahay, waa 2 jeer ka Si, si loo kordhiyo inta jeer ee aaladda iyo cufnaanta awoodda; Heerarka kuleylku waa sarreeyaa, in ka badan Si, qulqulka kulaylku waa sarreeyaa, koorsada kulaylka ayaa sarreeya, ka-hortagga kuleylka ayaa sarreeya, ka badan Si, kuleylka kuleylka ayaa sarreeya. Dhaqdhaqaaqa kulaylka sare, in ka badan 3 jeer ka Si, kordhinta awoodda kulaylka ee qalabka iyo xaqiijinta yaraynta qalabka.
