I-Semicera's P-uhlobo lwe-SiC Substrate Wafer yinxalenye ephambili yokuphuhlisa izixhobo zombane kunye ne-optoelectronic. Ezi wafers ziyilelwe ngokukodwa ukubonelela ukusebenza okongeziweyo kumandla aphezulu kunye nobushushu obuphezulu, ukuxhasa imfuno ekhulayo yezinto ezisebenzayo nezizinzileyo.
I-P-type doping kwii-wafers zethu ze-SiC iqinisekisa ukuphuculwa kombane kunye nokuhamba kwe-carrier carrier. Oku kubenza bafaneleke ngokukodwa kwizicelo kumandla ombane, ii-LED, kunye neeseli ze-photovoltaic, apho ukulahlekelwa kwamandla aphantsi kunye nokusebenza okuphezulu kubaluleke kakhulu.
Yenziwe ngeyona migangatho iphezulu yokuchaneka kunye nomgangatho, ii-wafers ze-SiC zohlobo lwe-Semicera zibonelela ngokufana komphezulu okugqwesileyo kunye neziphene ezincinci. Ezi mpawu zibalulekile kumashishini apho ukungaguquguquki kunye nokuthembeka kubalulekile, njengendawo ye-aerospace, izithuthi, kunye namacandelo amandla ahlaziyekayo.
Ukuzinikela kweSemicera ekuveliseni izinto ezintsha kunye nokugqwesa kuyabonakala kuhlobo lwethu lwe-P-SiC Substrate Wafer. Ngokudibanisa ezi wafers kwinkqubo yakho yokuvelisa, uyaqinisekisa ukuba izixhobo zakho ziyaxhamla kwiipropathi ezikhethekileyo zobushushu kunye nezombane ze-SiC, zibenza basebenze ngokufanelekileyo phantsi kweemeko ezinzima.
Utyalo-mali kuhlobo lwe-P-uhlobo lwe-SiC Substrate Wafer ithetha ukukhetha imveliso edibanisa inzululwazi yemathiriyeli ephuma phambili nobunjineli obucokisekileyo. I-Semicera izinikele ekuxhaseni isizukulwana esilandelayo setekhnoloji ye-elektroniki kunye ne-optoelectronic, ibonelela ngezinto ezibalulekileyo ezifunekayo kwimpumelelo yakho kwishishini le-semiconductor.
