4H-N 8 inch SiC substrate wafer Silicon Carbide Dummy Research grade 500um makulidwe Chithunzi Chowonetsedwa

Kufotokozera Kwachidule:

Ma wafer a silicon carbide amagwiritsidwa ntchito mu zipangizo zamagetsi monga ma power diode, ma MOSFET, zipangizo zama microwave amphamvu kwambiri, ndi ma RF transistors, zomwe zimathandiza kusintha mphamvu bwino komanso kuyang'anira mphamvu. Ma wafer a SiC ndi ma substrates amagwiritsidwanso ntchito mu zamagetsi zamagalimoto, machitidwe a ndege, ndi ukadaulo wa mphamvu zongowonjezwdwanso.

Kodi mumasankha bwanji ma Silicon Carbide Wafers ndi ma SiC Substrates?

Posankha ma wafer ndi ma substrate a silicon carbide (SiC), pali zinthu zingapo zofunika kuziganizira. Nazi mfundo zofunika:

Mtundu wa Zinthu: Dziwani mtundu wa zinthu za SiC zomwe zikugwirizana ndi ntchito yanu, monga 4H-SiC kapena 6H-SiC. Kapangidwe ka kristalo komwe kamagwiritsidwa ntchito kwambiri ndi 4H-SiC.

Mtundu wa Doping: Sankhani ngati mukufuna doping ya SiC yopangidwa ndi doping kapena yosapangidwa. Mitundu yodziwika bwino ya doping ndi N-type (n-doped) kapena P-type (p-doped), kutengera zomwe mukufuna.

Ubwino wa Crystal: Yesani mtundu wa kristalo wa ma wafer a SiC kapena ma substrates. Ubwino womwe mukufuna umatsimikiziridwa ndi magawo monga kuchuluka kwa zolakwika, mawonekedwe a crystallographic, ndi kuuma kwa pamwamba.

Chidutswa cha Wafer: Sankhani kukula koyenera kwa wafer kutengera momwe mwagwiritsira ntchito. Kukula kofala kumakhala mainchesi awiri, mainchesi atatu, mainchesi anayi, ndi mainchesi asanu ndi limodzi. Chidutswa cha wafer chikakhala chachikulu, mupeza phindu lalikulu pa wafer iliyonse.

Kukhuthala: Ganizirani makulidwe omwe mukufuna a ma wafer a SiC kapena ma substrate. Makulidwe omwe amagwiritsidwa ntchito nthawi zambiri amakhala kuyambira ma micrometer ochepa mpaka mazana angapo a ma micrometer.

Kuyang'ana: Dziwani momwe kristalographic imayenderana ndi zofunikira za pulogalamu yanu. Ma directions odziwika bwino ndi monga (0001) ya 4H-SiC ndi (0001) kapena (0001̅) ya 6H-SiC.

Kumaliza Pamwamba: Yesani kutsiriza kwa pamwamba pa ma wafer a SiC kapena substrates. Pamwamba pake payenera kukhala posalala, posalala, komanso popanda mikwingwirima kapena zodetsa.

Mbiri ya Wogulitsa: Sankhani wogulitsa wodalirika yemwe ali ndi luso lalikulu popanga ma wafers ndi ma substrates apamwamba a SiC. Ganizirani zinthu monga luso lopanga, kuwongolera khalidwe, ndi ndemanga za makasitomala.

Mtengo: Ganizirani za mtengo wake, kuphatikizapo mtengo wa wafer kapena substrate ndi zina zowonjezera zomwe zingawononge kusintha.

Ndikofunikira kuwunika mosamala zinthu izi ndikufunsa akatswiri amakampani kapena ogulitsa kuti muwonetsetse kuti ma wafer ndi ma substrate a SiC omwe mwasankha akukwaniritsa zofunikira zanu.
