SiCOI Wafer (Silicon Carbide-on-Insulator) Awọn ohun-ini Akopọ
Awọn wafers SiCOI jẹ sobusitireti iran-iran tuntun ti o n ṣajọpọ Silicon Carbide (SiC) pẹlu Layer idabobo, nigbagbogbo SiO₂ tabi oniyebiye, lati mu ilọsiwaju ṣiṣẹ ni ẹrọ itanna agbara, RF, ati awọn fọto. Ni isalẹ ni alaye Akopọ ti awọn ohun-ini wọn ti a pin si awọn apakan bọtini:
| Ohun ini | Apejuwe |
| Ohun elo Tiwqn | Silicon Carbide (SiC) Layer ti a so sori sobusitireti idabobo (ni deede SiO₂ tabi oniyebiye) |
| Crystal Be | Ni deede 4H tabi 6H polytypes ti SiC, ti a mọ fun didara gara ga ati isokan |
| Itanna Properties | Aaye ina gbigbẹ giga (~ 3 MV / cm), bandgap jakejado (~ 3.26 eV fun 4H-SiC), lọwọlọwọ jijo kekere |
| Gbona Conductivity | Imudani ti o ga julọ (~ 300 W / m · K), ti o mu ki ilọkuro ooru ṣiṣẹ daradara |
| Dielectric Layer | Layer insulating (SiO₂ tabi oniyebiye) pese ipinya itanna ati dinku agbara parasitic |
| Darí Properties | Lile giga (~ 9 Mohs asekale), agbara ẹrọ ti o dara julọ, ati iduroṣinṣin gbona |
| Dada Ipari | Ni deede ultra-dan pẹlu iwuwo abawọn kekere, o dara fun iṣelọpọ ẹrọ |
| Awọn ohun elo | Awọn ẹrọ itanna agbara, awọn ẹrọ MEMS, awọn ẹrọ RF, awọn sensọ to nilo iwọn otutu giga ati ifarada foliteji |
Awọn wafers SiCOI (Silicon Carbide-on-Insulator) ṣe aṣoju igbekalẹ sobusitireti semikondokito to ti ni ilọsiwaju, ti o ni ipele tinrin didara giga ti ohun alumọni carbide (SiC) ti a so mọ Layer idabobo, ni igbagbogbo silikoni oloro (SiO₂) tabi oniyebiye. Ohun alumọni carbide jẹ semikondokito bandgap jakejado ti a mọ fun agbara rẹ lati koju awọn foliteji giga ati awọn iwọn otutu ti o ga, pẹlu iṣiṣẹ igbona ti o dara julọ ati líle ẹrọ ti o ga julọ, ti o jẹ ki o jẹ apẹrẹ fun agbara giga, igbohunsafẹfẹ giga, ati awọn ohun elo itanna iwọn otutu giga.
Layer idabobo ni awọn wafers SiCOI n pese ipinya itanna to munadoko, dinku agbara parasitic ni pataki ati awọn ṣiṣan jijo laarin awọn ẹrọ, nitorinaa imudara iṣẹ ẹrọ gbogbogbo ati igbẹkẹle. Ilẹ wafer ti wa ni didan ni deede lati ṣaṣeyọri didan ultra pẹlu awọn abawọn to kere, ipade awọn ibeere lile ti iṣelọpọ ẹrọ micro- ati nano-iwọn.
Eto ohun elo yii kii ṣe ilọsiwaju awọn abuda itanna ti awọn ẹrọ SiC ṣugbọn tun mu iṣakoso igbona pupọ ati iduroṣinṣin ẹrọ. Bi abajade, SiCOI wafers ti wa ni lilo pupọ ni ẹrọ itanna agbara, awọn paati igbohunsafẹfẹ redio (RF), awọn sensọ microelectromechanical (MEMS), ati ẹrọ itanna iwọn otutu giga. Lapapọ, awọn wafers SiCOI darapọ awọn ohun-ini iyasọtọ ti ara ti ohun alumọni carbide pẹlu awọn anfani ipinya itanna ti Layer insulator, pese ipilẹ pipe fun iran atẹle ti awọn ẹrọ semikondokito iṣẹ-giga.

SiCOI wafer ká Q&A
Q:kini SiCOI wafer
A:SiCOI wafer duro fun Silicon Carbide-on-Insulator wafer. O jẹ iru sobusitireti semikondokito kan nibiti Layer tinrin ti ohun alumọni carbide (SiC) ti so mọ Layer idabobo, nigbagbogbo silikoni oloro (SiO₂) tabi nigbami oniyebiye. Eto yii jọra ni imọran si awọn wafer Silicon-on-Insulator (SOI) ti a mọ daradara ṣugbọn nlo SiC dipo ohun alumọni.
