Hais txog epitaxial wafers, Tuam Tshoj tau ua tiav cov txiaj ntsig zoo. Rau inch silicon carbide epitaxial khoom tuaj yeem muab tau hauv zos, thiab ib pawg ntawm cov khoom siv silicon carbide wafer tuaj yeem tsim lossis tsim. Piv txwv li, Ruineng's silicon carbide diode cov khoom thiab silicon carbide epitaxial khoom upstream ntawm kev lag luam saw twb tau sib tw ncaj qha nrog cov tuam txhab thoob ntiaj teb sab saum toj hauv kev lag luam txawv teb chaws.
Hais txog SiC cov khoom siv hluav taws xob, feem ntau ntawm cov khoom siv hluav taws xob siv los ntawm cov khoom siv hluav taws xob hauv tsev SiC raug xa tawm. 600-1700V SiC SBD thiab MOSFET tau ua lag luam txawv teb chaws, nrog cov khoom tseem ceeb hauv qab 1200V. Kev tshawb fawb thiab kev loj hlob ntawm 600-3300V SiC SBD nyob rau hauv Suav teb tau ua tiav thawj zaug, thiab nws tseem raug coj los siv rau hauv kev lag luam. Tib lub sijhawm, kev tshawb fawb thiab kev tsim kho ntawm 1200V / 50A SiC MOSFET kuj tau ua tiav. 6-inch SiC fais fab khoom siv kab ntawm CRRC Times, Century Golden Light, Ntiaj Teb Lub Zog Hluav Taws Xob Internet Tshawb Fawb, thiab CLP 55 Lub Tsev Haujlwm tau pib.
Raws li lub teb chaws nrog cov ntawv thov semiconductor loj tshaj plaws nyob rau hauv lub ntiaj teb, Tuam Tshoj tau paub txog qhov tseem ceeb ntawm kev tsim peb-tiam dav bandgap semiconductor kev lag luam. Cov kws tshaj lij kev lag luam tau kwv yees tias nyob rau tsib xyoos tom ntej no, Tuam Tshoj txoj kev lag luam semiconductor thib peb yuav nkag mus rau "lub sijhawm ncov". Kuv vam tias ntau lub lag luam tuaj yeem nqis peev hauv ntau qhov kev sib txuas ntawm silicon carbide kev lag luam saw, thiab tib lub sijhawm, kuv vam tias cov lag luam hauv kev lag luam tuaj yeem tsom mus rau kev tsim cov tshuab silicon carbide. Mature technology thiab cov khoom txhim khu kev qha yog lub hauv paus tseem ceeb ntawm kev tsim kho kev lag luam.
