Semicerawhakataki te850V High Power GaN-on-Si Epi Wafer, he pakaruhanga i roto i te auahatanga semiconductor. Ko tenei wafer epi matatau e whakakotahi ana i te kaha nui o Gallium Nitride (GaN) me te utu-whai hua o Silicon (Si), ka hangaia he otinga kaha mo nga tono ngaohiko teitei.
Āhuatanga matua:
•Te Whakahaere Ngaohiko Nui: I hangaia hei tautoko ki te 850V, he pai tenei GaN-on-Si Epi Wafer mo te tono hiko hiko, kia kaha ake ai te pai me te mahi.
•Whakanuia te Kiato Mana: Ma te pai o te hikohiko hiko me te kawe werawera, ka taea e te hangarau GaN nga hoahoa kiato me te pikinga o te hiko.
•Utu-Painga Rongoa: Ma te whakamahi i te silicon hei tïpako, ka tukuna e tenei angiangi epi he utu utu nui ki nga angiangi GaN tuku iho, me te kore e whakararu i te kounga me te mahi.
•Awhe Taupānga Whānui: He tino pai mo te whakamahi i nga kaitahuri hiko, RF amplifiers, me etahi atu taputapu hiko hiko teitei, e whakarite ana i te pono me te mauroa.
Te torotoro i te heke mai o te hangarau ngaohiko teitei me Semicera's850V High Power GaN-on-Si Epi Wafer. I hoahoatia mo nga tono tapahi-mata, ma tenei hua e whakarite kia mahi o taputapu hiko me te tino pai me te pono. Whiriwhiria a Semicera mo o hiahia reanga hikohiko.
