Chigadzirwa Specification
Silicon carbide (SiC) is a compound semiconductor material inoumbwa nezvinhu kabhoni nesilicon, uye ndechimwe chezvinhu zvakanakira kugadzira tembiricha, high-frequency, high-power and high-voltage devices. Kana ichienzaniswa neyechinyakare silicon zvinhu (Si), iyo inorambidzwa bhendi yakafara yesilicon carbide yakapetwa katatu iyo yesilicon; thermal conductivity ndeye 4-5 nguva yesilicon; iyo yekuputsika voltage ndeye 8-10 nguva yesilicon; uye electron saturation drift rate ndeye 2-3 nguva yesilicon, iyo inosangana nezvinodiwa neindasitiri yemazuva ano ye-high-power, high-voltage, uye high-frequency, uye inonyanya kushandiswa kugadzira-high-speed, high-frequency, high-power uye chiedza-emitting electronic components, uye nzvimbo dzayo dzepasi pekushandisa dzinosanganisira smart, grid, photovoltaic field, 5G simba remhepo. yemidziyo yemagetsi, silicon carbide diodes uye MOSFETs dzatanga kushandiswa kutengeserana.
Zvakanakira zveSiC wafers / SiC substrate
High tembiricha kuramba. Iyo inorambidzwa bhendi upamhi hwesilicon carbide inopeta 2-3 kupfuura yesilicon, saka maerekitironi haanyanyi kusvetuka patembiricha yakakwira uye anogona kumira tembiricha yepamusoro yekushandisa, uye thermal conductivity yesilicon carbide ndeye 4-5 nguva yesilicon, zvichiita kuti zvive nyore kuburitsa kupisa kubva pachigadzirwa uye kubvumira kune yakanyanya kudzikisira tembiricha yekushandisa. Hunhu hwepamusoro-tembiricha hunogona kuwedzera zvakanyanya kuwanda kwesimba, uku ichidzikisa zvinodikanwa zveiyo kupisa dissipation system, zvichiita kuti terminal iwedzere kureruka uye miniaturised.
High voltage resistance. Silicon carbide's breakdown field strength is 10 times that of silicon, ichiita kuti ikwanise kumira nepamusoro-soro, zvichiita kuti ive yakakodzera kune yakakwirira-voltage michina.
High-frequency resistance. Silicon carbide ine zvakapetwa kaviri iyo saturation electron Drift rate yesilicon, zvichikonzera kuti zvigadziriso zvayo mukuvharwa hazvipo mune yazvino yekudhonza chiitiko, inogona zvinobudirira kuvandudza mudziyo wekuchinja frequency, kuti uwane mudziyo miniaturisation.
Kupera simba kwakaderera. Silicon carbide ine yakanyanya kuderera pa-kupikisa kana ichienzaniswa nesilicon zvinhu, yakaderera conduction kurasikirwa; panguva imwecheteyo, iyo yakakwirira bandwidth yesilicon carbide inoderedza zvakanyanya kudonha ikozvino, kurasikirwa kwesimba; uyezve, silicon carbide zvishandiso mukuvhara maitiro haipo mune yazvino dhiza chiitiko, yakaderera switching kurasikirwa.
