3 nti Dia76.2 hli SiC substrates HPSI Prime Research thiab Dummy qib

Cov khoom siv hluav taws xob: hais txog qhov tsis kam ntawm 15 ~ 30mΩ-cm silicon carbide substrate. Cov silicon carbide epitaxial wafer uas cog los ntawm cov khoom siv hluav taws xob silicon carbide substrate tuaj yeem ua rau cov khoom siv hluav taws xob ntxiv, uas siv dav hauv cov tsheb fais fab tshiab, photovoltaics, smart grids, thiab kev thauj mus los ntawm tsheb ciav hlau.

Semi-insulating substrate yog hais txog lub substrate silicon carbide uas muaj resistivity siab dua 100000Ω-cm, feem ntau yog siv rau hauv kev tsim cov gallium nitride microwave xov tooj cua zaus, thiab yog lub hauv paus ntawm kev sib txuas lus wireless.

Nws yog ib qho tseem ceeb hauv kev sib txuas lus wireless.

Cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob semi-insulating silicon carbide siv rau hauv ntau yam khoom siv hluav taws xob thiab cov khoom siv fais fab, suav nrog tab sis tsis txwv rau cov hauv qab no:

Cov khoom siv semiconductor muaj zog heev (conductive): Silicon carbide substrates muaj lub zog tawg siab thiab thermal conductivity, thiab tsim nyog rau kev tsim cov transistors muaj zog siab thiab diodes thiab lwm yam khoom siv.

Cov khoom siv hluav taws xob RF (semi-insulated): Silicon Carbide substrates muaj qhov ceev hloov pauv siab thiab lub zog kam rau siab, tsim nyog rau cov ntawv thov xws li RF fais fab amplifiers, microwave khoom siv thiab cov hloov pauv zaus siab.

Cov khoom siv Optoelectronic (semi-insulated): Silicon carbide substrates muaj qhov sib txawv ntawm lub zog thiab kev ruaj khov thermal siab, tsim nyog rau kev ua photodiodes, lub hnub ci hlwb thiab laser diodes thiab lwm yam khoom siv.

Cov ntsuas kub (conductive): Silicon carbide substrates muaj cov thermal conductivity siab thiab thermal stability, tsim nyog rau kev tsim cov sensors kub siab thiab cov cuab yeej ntsuas kub.

Cov txheej txheem tsim khoom thiab daim ntawv thov ntawm silicon carbide conductive thiab semi-insulating substrates muaj ntau yam teb thiab peev xwm, muab cov hauv kev tshiab rau kev txhim kho cov khoom siv hluav taws xob thiab cov khoom siv fais fab.
