Pakali pano, mkokomo womwe ukukula wofuna kuteteza chilengedwe ndi kuteteza mphamvu wachititsa kuti magalimoto amagetsi atsopano adziŵike bwino. Zipangizo zamagetsi zamphamvu kwambiri zimagwira ntchito yofunika kwambiri pakuwongolera liwiro lagalimoto ndikusunga ma AC ndi DC. Kuthamanga kwapang'onopang'ono kwapang'onopang'ono kumayika zofunikira pakuchotsa kutentha kwapaketi yamagetsi, pomwe zovuta ndi kusiyanasiyana kwa malo ogwirira ntchito zimafunikira zolongedza kuti zikhale ndi mphamvu zotha kutenthedwa ndi kutentha kwambiri kuti zithandizire. Kuonjezera apo, ndi chitukuko chofulumira cha zamakono zamakono zamagetsi zamagetsi, zomwe zimadziwika ndi magetsi apamwamba, apamwamba kwambiri, komanso maulendo apamwamba, kutentha kwa kutentha kwa ma modules amphamvu omwe amagwiritsidwa ntchito pa teknolojiyi kwakhala kovuta kwambiri. Zida za ceramic zomwe zili m'makina opaka pakompyuta ndizomwe zimafunikira pakuchotsa kutentha moyenera, zimakhalanso ndi mphamvu zambiri komanso zodalirika potengera zovuta zomwe zimagwirira ntchito. Magawo akuluakulu a ceramic omwe apangidwa mochuluka komanso ogwiritsidwa ntchito kwambiri m'zaka zaposachedwa ndi Al2O3, BeO, SiC, Si3N4, AlN, etc.
Al2O3 ceramic imagwira ntchito yofunika kwambiri potengera kutentha kwa gawo lapansi potengera njira yake yosavuta yokonzekera, kutchinjiriza bwino komanso kukana kutentha kwambiri. Komabe, kutsika kwa matenthedwe a matenthedwe a Al2O3 sikungakwaniritsidwe zofunika za kakulidwe ka chipangizo chamagetsi okwera kwambiri, ndipo kumagwira ntchito kumalo ogwirira ntchito komwe kuli ndi zofunikira zoziziritsira kutentha pang'ono. Kuphatikiza apo, mphamvu yopindika yotsika imachepetsanso kuchuluka kwa ma ceramics a Al2O3 ngati magawo otenthetsera kutentha.
Magawo a BeO ceramic amakhala ndi matenthedwe apamwamba komanso otsika kwambiri a dielectric kuti akwaniritse zofunikira pakuwotcha koyenera. Koma sizothandiza kugwiritsa ntchito kwakukulu chifukwa cha kawopsedwe kake, komwe kumakhudza thanzi la ogwira ntchito.
AlN ceramic imadziwika kuti ndi chinthu chothandiza pochotsa kutentha chifukwa cha kuchuluka kwa matenthedwe ake. Koma AlN ceramic ili ndi kulephera kupirira kutenthedwa kwa kutentha, kunyozeka kosavuta, kulimba kwapang'onopang'ono ndi kulimba mtima, zomwe sizingathandize kugwira ntchito m'malo ovuta, ndipo ndizovuta kutsimikizira kudalirika kwa mapulogalamu.
SiC ceramic ili ndi matenthedwe okwera kwambiri, chifukwa cha kutayika kwa dielectric kwambiri komanso voteji yocheperako, siyoyenera kugwiritsa ntchito m'malo othamanga kwambiri komanso magetsi.
Si3N4 imadziwika ngati chinthu chabwino kwambiri cha ceramic substrate chokhala ndi matenthedwe apamwamba komanso odalirika kwambiri kunyumba ndi kunja. Ngakhale matenthedwe a Si3N4 ceramic substrate ndi otsika pang'ono kuposa a AlN, mphamvu yake yosinthika komanso kulimba kwa fracture kumatha kufika kuwirikiza kawiri kuposa AlN. Pakadali pano, kutentha kwa Si3N4 ceramic ndikokwera kwambiri kuposa Al2O3 ceramic. Kuphatikiza apo, gawo la kukula kwa matenthedwe a Si3N4 ceramic substrates ndi lofanana ndi la SiC crystals, 3rd generation semiconductor substrate, lomwe limathandiza kuti lifanane kwambiri ndi SiC crystal material. Zimapangitsa Si3N4 kukhala chinthu chokondedwa cha magawo apamwamba otenthetsera matenthedwe a zida zamagetsi za 3rd SiC semiconductor power.
