The 4-inch high-purity semi-insulated silikoni carbide iwiri mbali kupukuta mbale amagwiritsidwa ntchito makamaka 5G kulankhulana ndi zina, ndi ubwino kuwongolera wailesi pafupipafupi osiyanasiyana, kopitilira muyeso mtunda kuzindikira, anti-kusokoneza, mkulu-liwiro. , kutumiza zidziwitso zazikuluzikulu ndi ntchito zina, ndipo imawonedwa ngati gawo lapansi loyenera kupanga zida zamagetsi zama microwave.

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 electron saturation drift rate ndi 2-3 nthawi ya silicon, yomwe imakwaniritsa zofunikira zamakampani amakono amphamvu kwambiri, magetsi apamwamba, ndi maulendo apamwamba, ndipo amagwiritsidwa ntchito makamaka popanga kuthamanga kwambiri, mafupipafupi, magetsi apamwamba kwambiri komanso magetsi otulutsa kuwala, ndi madera ake ogwiritsira ntchito pansi pake amaphatikizapo gridi yanzeru, Magalimoto amagetsi atsopano, mphamvu ya mphepo ya photovoltaic, mauthenga a 5G, ndi zina zotero. ya zida zamagetsi, ma silicon carbide diode ndi ma MOSFET ayamba kugulitsidwa.

Ubwino wa SiC wafer / SiC gawo lapansi

Kukana kutentha kwakukulu. Gulu loletsedwa la silicon carbide ndi 2-3 nthawi ya silicon, kotero ma elekitironi sangathe kudumpha pa kutentha kwakukulu ndipo amatha kupirira kutentha kwapamwamba, ndipo matenthedwe a silicon carbide ndi 4-5 nthawi ya silicon, kupanga. ndikosavuta kutulutsa kutentha kuchokera ku chipangizocho ndikulola kutentha kocheperako kwambiri. 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 kusintha kusintha.
