The 4-inchi mkulu-kuyera theka-insulated silikoni carbide awiri mbali kupukuta mbale zimagwiritsa ntchito 5G kulankhulana ndi madera ena, ndi ubwino kuwongolera wailesi pafupipafupi osiyanasiyana, kopitilira muyeso-atali kuzindikira, odana kusokoneza, mkulu-liwiro, lalikulu mphamvu kufala uthenga ndi ntchito zina, ndipo amatengedwa ngati zipangizo zabwino microwave mphamvu.

Silicon carbide (SiC) ndi zinthu zopangira semiconductor zomwe zimapangidwa ndi zinthu za carbon ndi silicon, ndipo ndi chimodzi mwazinthu zabwino zopangira zida zotentha kwambiri, zothamanga kwambiri, zamphamvu kwambiri komanso zamagetsi. Poyerekeza ndi zinthu zachikhalidwe za silicon (Si), gulu loletsedwa la silicon carbide ndi kuwirikiza katatu kuposa silicon; matenthedwe madutsidwe ndi 4-5 nthawi silicon; mphamvu yowonongeka ndi 8-10 nthawi ya silicon; ndi ma elekitironi machulukitsidwe kutengeka mlingo ndi 2-3 nthawi ya pakachitsulo, amene amakwaniritsa zofuna za makampani amakono kwa mkulu-mphamvu, mkulu-voteji, ndi mkulu-pafupipafupi, ndipo makamaka ntchito kupanga mkulu-liwiro, mkulu-pafupipafupi, mkulu-mphamvu ndi kuwala-kutulutsa zigawo zamagetsi, ndi m'madera ake otsika ntchito monga anzeru, gululi mphamvu, photo volta kumunda mphamvu kulankhulana. ya zida zamagetsi, ma silicon carbide diode ndi ma MOSFET ayamba kugulitsidwa.

Ubwino wa SiC wafer / SiC gawo lapansi

Kukana kutentha kwakukulu. The choletsedwa gulu m'lifupi mwake pakachitsulo carbide ndi 2-3 nthawi ya pakachitsulo, kotero ma elekitironi sangadumphe pa kutentha kwambiri ndipo akhoza kupirira kutentha ntchito patali, ndi matenthedwe madutsidwe pa silicon carbide ndi 4-5 nthawi silicon, kupangitsa kukhala kosavuta dissipate kutentha kwa chipangizo ndi kulola kwa apamwamba kuchepetsa kutentha ntchito. Makhalidwe a kutentha kwambiri amatha kuonjezera mphamvu zowonjezera mphamvu, pamene amachepetsa zofunikira pazitsulo zowonongeka, zomwe zimapangitsa kuti terminal ikhale yopepuka komanso yochepa.

High voltage resistance. Mphamvu yakuwonongeka kwa Silicon carbide ndi kuwirikiza ka 10 kuposa ya silicon, zomwe zimapangitsa kuti izitha kupirira ma voltages apamwamba, ndikupangitsa kuti ikhale yoyenera pazida zamagetsi zamagetsi.

High-frequency resistance. Silicon carbide ali kawiri machulukitsidwe elekitironi kutengeka mlingo wa pakachitsulo, chifukwa zipangizo zake mu ndondomeko shutdown kulibe mu zochitika panopa kuukoka, akhoza bwino kusintha chipangizo kusintha pafupipafupi, kukwaniritsa chipangizo miniaturisation.

Kutaya mphamvu zochepa. Silicon carbide imakhala yotsika kwambiri pakukana poyerekeza ndi zida za silicon, kutayika kochepa kwa conduction; pa nthawi yomweyo, bandiwifi mkulu wa pakachitsulo carbide kwambiri amachepetsa kutayikira panopa, kutaya mphamvu; Komanso, silicon carbide zipangizo mu ndondomeko shutdown kulibe mu kukoka chodabwitsa panopa, otsika lophimba imfa.
