LED Iti/Iti
GaN Whakararuraru i runga i te Hangarau Silicon Micro LED Maramara
Whakaahuatanga Hua
He whānui ngā tūmanakohanga whanaketanga o te hangarau whakaaturanga hou o te Micro LED, ā, ka taea te whakamahi ki ngā mōhiti AR, HUD, rama waka ADB, whakaaturanga mārama me ētahi atu mara whānui. Ka taea e te hangarau Micro LED i runga ake i te papa silicon GaN 8-inihi me te anga taraiwa silicon CMOS te whakawhirinaki ki ngā taputapu me ngā tukanga ara iahiko whakauru kua pakeke, koinei te huarahi ahumahi e kore e taea te karo mō te hanga Micro-LED iti te utu, teitei te hua.
I runga i te tata ki te 20 tau o te kohikohinga ahumahi i roto i te mekameka LED papa silicon katoa, kua whakawhanakehia e mātou he papa silicon 4-inihi ki te 12-inihi InGaN-e hangai ana ki ngā anga epitaxial tata-ultraviolet, kikorangi, kakariki, me te whero mō ngā tono Micro LED, mai i te 365nm ki te 650nm. Kua mahia te arotautanga whānui i runga i ngā tohu ahumahi matua pēnei i te whai hua o te mārama, te ōritetanga, me te pono, ā, i runga i tēnei kaupapa, kua angitu te whakawhanake i ngā rarangi whakaaturanga micro-LED whero, kakariki, me te kikorangi.
E whakapau kaha ana te kamupene ki te whakarato i ngā maramara epitaxial Micro LED me ngā kōwae taputapu kounga teitei, he papa hiko silicon kounga teitei, ki ngā kiritaki huri noa i te ao, hei whakahaere i ngā tono mutunga kore a Metaverse.
Ngā Āhuatanga me ngā Painga
Mai i te tirohanga o te ahumahi, Mā te whakamahi i te hangarau GaN silicon nui-rahi hei whakarite i te Micro LED:
1. he maha ngā painga pēnei i te rahi nui, te utu iti, te tango i te papa kore-ngaro, me te hototahi ki ngā tukanga IC;
2. Ki te whakatauritea ki te papa 4-inihi, ka piki ake te putanga maramara Micro LED mō ia waeine horahanga papa mā te 25% me te papa 8-inihi;
3. Mā te whakamahi i tētahi papa silicon 8-inihi hei whakarite i te Micro LED, ko te utu BOM o ia wae whakaatu he 30% noa iho i tērā o tētahi otinga hapaira 4-inihi (tae atu ki te epitaxy, ngā maramara me te CMOS).
