2 inch Sic silicon carbide substrate 6H-N Rudzi 0.33mm 0.43mm kupolisha kwemativi maviri Kupisa kwakanyanya kunoshandisa simba shoma

2 inch Sic silicon carbide substrate 6H-N Rudzi 0.33mm 0.43mm kupolisha kwemativi maviri Kupisa kwakanyanya Kushandiswa kwesimba shoma Mufananidzo Wakatsanangurwa

Tsananguro pfupi:

Silicon carbide (SiC) chinhu chinopa mukana wakakura wekushandisa semiconductor chine thermal conductivity yakanaka uye chemical stability.6H-Nzvinoratidza kuti chimiro chayo chekristaro chine hexagonal (6H), uye "N" inoratidza kuti imhando yeN-type semiconductor material, iyo inowanzo kuwanikwa nekushandisa nitrogen.
Substrate yesilicon carbide ine hunhu hwakanaka hwekudzivirira kumanikidzwa kwakanyanya, kudzivirira kupisa kwakanyanya, kushanda kwema frequency akawanda, nezvimwewo. Kana tichienzanisa nezvigadzirwa zvesilicon, mudziyo wakagadzirwa nesilicon substrate unogona kuderedza kurasikirwa ne80% uye kuderedza saizi yemudziyo ne90%. Panyaya yemotokari itsva dzesimba, silicon carbide inogona kubatsira mota itsva dzesimba kuwana huremu hwakareruka uye kuderedza kurasikirwa, uye kuwedzera huwandu hwekutyaira; Mumunda wekutaurirana kwe5G, inogona kushandiswa kugadzira michina ine chekuita nayo; Mukugadzira simba re photovoltaic kunogona kuvandudza mashandiro ekushandura; Munda wekufambisa njanji unogona kushandisa hunhu hwawo hwekupisa kwakanyanya uye hwekudzivirira kumanikidzwa kwakanyanya.

Zvinhu zvirimo

Izvi zvinotevera ndizvo zvinoitwa ne 2inch silicon carbide wafer

1. Kuomarara: Kuomarara kweMohs kunenge 9.2.
2. Chimiro chekristaro: chimiro chejira remativi matanhatu.
3. Kupisa kwakanyanya: kupisa kweSiC kwakanyanya kupfuura kwesilicon, izvo zvinobatsira kuti kupisa kuparare zvakanaka.
4. Mukana webhendi wakafara: mukana webhendi weSiC unenge 3.3eV, wakakodzera kushandiswa pakupisa kwakanyanya, mafrequency akawanda uye simba rakawanda.
5. Kukanganiswa kwesimba remagetsi uye kufamba kwemaerekitironi: Kukanganiswa kwakanyanya kwesimba remagetsi uye kufamba kwemaerekitironi, zvakakodzera zvishandiso zvemagetsi zvine simba zvinobudirira zvakaita seMOSFET neIGBTs.
6. Kugadzikana kwemakemikari uye kuramba mwaranzi: yakakodzera nharaunda dzakaoma dzakadai semuchadenga nekudzivirira nyika. Kuramba makemikari zvakanaka, acid, alkali nezvimwe zvinonyungudutsa makemikari.
7. Simba guru remuchina: Simba guru remuchina kana tembiricha yakakwira uye mamiriro ekumanikidzwa akakwira.
Inogona kushandiswa zvakanyanya mumidziyo yemagetsi ine simba guru, mafrequency akawanda uye tembiricha yepamusoro, senge ma ultraviolet photodetectors, ma photovoltaic inverters, ma PCU emotokari dzemagetsi, nezvimwewo.

Wafer ye silicon carbide ye 2inch ine mashandisirwo akasiyana-siyana.

1. Zvishandiso zvemagetsi zvine simba: zvinoshandiswa kugadzira MOSFET, IGBT nezvimwe zvishandiso zvine simba guru, zvinoshandiswa zvakanyanya mukushandura simba uye mota dzemagetsi.

2. Zvishandiso zveRf: Mumidziyo yekutaurirana, SiC inogona kushandiswa muma amplifiers ane frequency yakakwira uye ma amplifiers eRF power.

3. Zvishandiso zvemagetsi: zvakaita semaLED akavakirwa paSIC, kunyanya mukushandiswa kwebhuruu ne ultraviolet.

4.Masensa: Nekuda kwekupisa kwayo kwakanyanya uye kusakwanisa kushandisa makemikari, maSiC substrates anogona kushandiswa kugadzira masensa ekupisa kwakanyanya uye mamwe mashandisirwo emasensa.

5. Zvemauto nendege: nekuda kwekudzivirira kupisa kwakanyanya uye hunhu hwayo hwesimba rakawanda, yakakodzera kushandiswa munzvimbo dzakanyanya.

Nzvimbo huru dzekushandisa dze6H-N type 2 "SIC substrate dzinosanganisira mota itsva dzemagetsi, nzvimbo dzekutumira nekushandura magetsi ane voltage yakakwira, zvinhu zvichena, zvitima zvinomhanya zvakanyanya, mota, inverter yemagetsi, simba remagetsi rinotenderera nezvimwewo.

XKH inogona kugadziriswa nehukobvu hwakasiyana zvichienderana nezvinodiwa nevatengi. Kune nzira dzakasiyana dzekurapa pamusoro pechinhu nekupolisha. Mhando dzakasiyana dzekushandisa mushonga (senge nitrogen doping) dzinotsigirwa. Nguva yekutumira imavhiki maviri kusvika mana, zvichienderana nemaitiro azvo. Shandisa zvinhu zvekurongedza zvinodzivirira static uye anti-seismic foam kuti uve nechokwadi chekuti substrate yakachengeteka. Pane nzira dzakasiyana dzekutumira, uye vatengi vanogona kutarisa mamiriro ezvekufambisa zvinhu munguva chaiyo kuburikidza nenhamba yekutevera yakapihwa. Ipa rutsigiro rwehunyanzvi uye masevhisi ekubvunza kuti uve nechokwadi chekuti vatengi vanogona kugadzirisa matambudziko panguva yekushandisa.
