He aha nā hemahema o ka papa epitaxial silicon carbide
na ka luna hoʻomalu ma 24-06-05
ʻO ka ʻenehana koʻikoʻi no ka ulu ʻana o nā mea epitaxial SiC ʻo ia ka ʻenehana kaohi kīnā mua, ʻoi aku hoʻi no ka ʻenehana kaohi kīnā i maʻalahi i ka hāʻule ʻana o ka hāmeʻa a i ʻole ka hōʻino ʻana o ka hilinaʻi. ʻO ke aʻo ʻana i ke ʻano o nā hemahema substrate e hoʻonui ana i ka epi...

ʻO ka ʻenehana ulu ʻokiʻoki a me ka ulu ʻana o ka epitaxial-Ⅱ
na ka luna hoʻomalu ma 24-05-30
2. Ka ulu ʻana o ka ʻili lahilahi Epitaxial Hāʻawi ka substrate i kahi papa kākoʻo kino a i ʻole ka papa alakaʻi no nā mea mana Ga2O3. ʻO ka papa koʻikoʻi aʻe ʻo ia ka papa kahawai a i ʻole ka papa epitaxial i hoʻohana ʻia no ke kū'ē ʻana i ka voltage a me ka lawe ʻana i ka mea lawe. I mea e hoʻonui ai i ka voltage breakdown a hoʻemi i ka con...

ʻO ka ʻenehana ulu epitaxial a me ke aniani hoʻokahi o Gallium oxide
na ka luna hoʻomalu ma 24-05-30
Ua loaʻa i nā semiconductors bandgap ākea (WBG) i hōʻike ʻia e ka silicon carbide (SiC) a me ka gallium nitride (GaN) ka nānā nui ʻia. Loaʻa i ka poʻe nā manaʻolana kiʻekiʻe no nā manaʻolana noi o ka silicon carbide i nā kaʻa uila a me nā pūnaewele mana, a me nā manaʻolana noi o ka gallium...

He aha nā pale loea i ka silicon carbide? II
na ka luna hoʻomalu ma 24-05-22
ʻO nā pilikia loea i ka hana paʻa ʻana i nā wafers silicon carbide kiʻekiʻe me ka hana paʻa: 1) ʻOiai pono e ulu nā kristal i kahi ʻano sila wela kiʻekiʻe ma luna o 2000°C, kiʻekiʻe loa nā koi kaohi mahana; 2) ʻOiai ua loaʻa i ka silicon carbide ...

He aha nā keʻakeʻa loea i ka silicon carbide?
na ka luna hoʻomalu ma 24-05-22
ʻO ka hanauna mua o nā mea semiconductor e hōʻike ʻia e ka silicon kuʻuna (Si) a me ka germanium (Ge), ʻo ia ke kumu no ka hana ʻana i ka kaapuni hoʻohui. Hoʻohana nui ʻia lākou i nā transistors a me nā mea ʻike haʻahaʻa haʻahaʻa, alapine haʻahaʻa, a me ka mana haʻahaʻa. ʻOi aku ma mua o 90% o nā huahana semiconductor...

Pehea e hana ʻia ai ka pauka SiC micro?
na ka luna hoʻomalu ma 24-05-13
ʻO ke aniani hoʻokahi SiC kahi mea semiconductor hui pū ʻia ʻo Group IV-IV i haku ʻia me ʻelua mau mea, ʻo Si a me C, ma kahi lakio stoichiometric o 1: 1. ʻO kona paʻakikī ka lua wale nō i ka daimana. ʻO ke ʻano hoʻemi kalapona o ka silicon oxide e hoʻomākaukau ai iā SiC e pili nui ana i ka formula hopena kemika ma lalo nei...

Pehea e kōkua ai nā papa epitaxial i nā polokalamu semiconductor?
na ka luna hoʻomalu ma 24-05-13
ʻO ke kumu o ka inoa epitaxial wafer ʻO ka mea mua, e hoʻolaha kākou i kahi manaʻo liʻiliʻi: ʻo ka hoʻomākaukau ʻana o ka wafer e pili ana i ʻelua mau loulou nui: ka hoʻomākaukau ʻana o ka substrate a me ke kaʻina hana epitaxial. ʻO ka substrate kahi wafer i hana ʻia me ka mea semiconductor single crystal. Hiki i ka substrate ke komo pololei i ka wafer manufactur...

Hoʻolauna i ka ʻenehana hoʻokomo ʻili lahilahi kemika (CVD)
na ka luna hoʻomalu ma 24-05-06
ʻO ka Chemical Vapor Deposition (CVD) kahi ʻenehana waiho ʻili lahilahi koʻikoʻi, i hoʻohana pinepine ʻia e hoʻomākaukau i nā ʻano kiʻiʻoniʻoni hana like ʻole a me nā mea papa lahilahi, a hoʻohana nui ʻia i ka hana semiconductor a me nā ʻoihana ʻē aʻe. 1. Ke kumu hana o CVD I ke kaʻina hana CVD, kahi precursor gas (hoʻokahi a i ʻole...
