Hoʻomaka a hoʻohana ʻia ka huahana: Hoʻokomo ʻia nā ʻāpana 41 o 4 mau hola substrate, hoʻohana ʻia no ka ulu ʻana o LED me ka kiʻiʻoniʻoni epitaxial polū-'ōmaʻomaʻo.

Kahi o ka mea hana o ka huahana: i loko o ke keʻena pane, e pili pono ana me ka wafer

ʻO nā huahana o lalo: nā ʻāpana LED

Makeke hope nui: LED

1. Kiʻekiʻe wela oxidation kū'ē:
ʻOi aku ka maikaʻi o ka pale ʻana i ka oxidation i ka wā e kiʻekiʻe ai ka mahana e like me 1600 ℃.
2. Maʻemaʻe kiʻekiʻe: hana ʻia e ka hoʻoheheʻe ʻana i ka mahu ma lalo o ke kūlana chlorination kiʻekiʻe.
3. Erosion kū'ē: kiʻekiʻe paakiki, paʻaʻiliʻili, maikaʻi particles.
4. Ke kū'ē i ka corrosion: acid, alkali, paʻakai a me nā mea hoʻoulu.
