Parizvino, mheremhere iri kukura yekuchengetedzwa kwezvakatipoteredza nekuchengetedza simba kwaunza motokari dzemagetsi emagetsi matsva. Zvishandiso zvepasuru yemagetsi epamusoro zvinoita basa rakasimba pakudzora kumhanya kwemotokari uye kuchengetedza kushandura AC neDC. Kuchovha bhasikoro kwepamusoro-frequency kwakaisa zvinodiwa zvakasimba pakubvisa kupisa kwemagetsi ekurongedza, ukuwo kuomarara nekusiyana-siyana kwenzvimbo yekushanda kunoda zvekurongedzerwa kuti zvive zvakanaka zvinodzivirira kupisa kwekupisa uye simba guru kuti riite basa rinotsigira. Pamusoro pezvo, nekukurumidza kuvandudzwa kwemagetsi emagetsi tekinoroji emazuva ano, ayo anoratidzwa nemagetsi akakwira, yakakwira ikozvino, uye yakakwira frequency, kupisa kwekudziya kwemamodule emagetsi akaiswa kune iyi tekinoroji kwave kunetsa. Zvishandiso zveceramic substrate mumagetsi ekurongedza masisitimu ndiwo kiyi yekubvisa kupisa kwakanaka, ivo zvakare vane simba rakakura uye kuvimbika mukupindura kuoma kwenzvimbo yekushanda. Iwo makuru eceramic substrates ayo akagadzirwa-zhinji uye akashandiswa zvakanyanya mumakore achangopfuura ndeye Al2O3, BeO, SiC, Si3N4, AlN, nezvimwe.
Al2O3 Ceramic inoita basa rakakosha muindasitiri yekubvisa kupisa kwepasi zvichienderana negadziriro yayo iri nyore yekugadzirira, kuvharisa kwakanaka uye kushivirira kwepamusoro. Zvakadaro, kudzika kwemafuta eAl2O3 hakugone kuzadzisa zvinodiwa pakuvandudzwa kwesimba repamusoro uye mudziyo wemagetsi wakakwira, uye unoshanda chete kunzvimbo yekushanda ine zvinodiwa zvekubvisa kupisa kwakaderera. Uyezve, iyo yakaderera kubhenda simba zvakare inodzikamisa chiyero chekushandisa cheAl2O3 ceramics sematanho ekupisa kupisa.
BeO ceramic substrates ine high thermal conductivity uye yakaderera dielectric nguva dzose kuti isangane nezvinodiwa zvehunobudirira kupisa kupisa. Asi hazvikodzeri kukushandisa kwakakura nekuda kwehupfu hwayo, hunokanganisa hutano hwevashandi.
AlN Ceramic inoonekwa sechinhu chemumiriri chechikamu chekupisa kupisa nekuda kwekukwira kwayo kwekushisa. Asi AlN ceramic ine pasina thermal shock resistance, nyore deliquescence, kusimba kwakaderera uye kuomarara, izvo zvisingakodzeri kushanda munzvimbo yakaoma, uye zvinonetsa kuona kuvimbika kwekushandisa.
SiC ceramic ine high thermal conductivity, nekuda kwekurasikirwa kwayo kwedielectric yakakwira uye low breakdown voltage, haikodzere maapplication ari muhigh frequency and voltage operating environments.
Si3N4 inozivikanwa seyakanakisa ceramic substrate material ine high thermal conductivity uye kuvimbika kwakanyanya kumba nekune dzimwe nyika. Kunyangwe iyo inodziya conductivity yeSi3N4 ceramic substrate yakadzikira zvishoma pane iyo yeAlN, simba rayo rekuchinjika uye kuomarara kwekutsemuka kunogona kusvika zvakapetwa kaviri izvo zveAlN. Zvichakadaro, iyo yekupisa conductivity yeSi3N4 ceramic yakanyanya kukwirira kupfuura iyo yeAl2O3 ceramic. Pamusoro pezvo, iyo coefficient of thermal expansion yeSi3N4 ceramic substrates iri pedyo neiyo yeSiC crystals, 3rd generation semiconductor substrate, izvo zvinoita kuti ienderane zvakanyanya kugadzikana neSiC crystal material. Inogadzira Si3N4 iyo inosarudzika zvinhu zveyakakwira yekupisa conductivity substrates yechitatu chizvarwa SiC semiconductor magetsi emagetsi.
