Nā noi keramika alumina i ka hana ʻana o Semiconductor

He kuleana koʻikoʻi ko nā keramika alumina i ka hana semiconductor, ʻike nui ʻia kāna noi ma nā ʻano aʻe:

Ka mua,Noi maka hoʻopili ʻana o ka hāmeʻa

He kiʻekiʻe ka conductivity thermal o nā keramika alumina, ka insulation uila maikaʻi a me ka ikaika kiʻekiʻe, e lilo ia i mea kūpono no ka hoʻopili ʻana i nā hāmeʻa semiconductor.

1. Ke alakaʻi wela kiʻekiʻe: hiki i ka ʻōpala keramika alumina ke hoʻomaikaʻi maikaʻi i ka hana wela o ka hāmeʻa, e hōʻemi i ka hoʻohana ʻana i ka mana, a laila e hoʻomaikaʻi ai i ke kūpaʻa a me ka hilinaʻi o nā hāmeʻa semiconductor.

2. Hoʻopaʻa uila: he mea hoʻopaʻa uila maikaʻi loa nā keramika alumina, hiki ke kū'ē i ke au kiʻekiʻe loa, e pale pono ana i nā mea semiconductor mai ka haʻalulu uila a i ʻole kaapuni pōkole a me nā hemahema ʻē aʻe.

3. Ikaika kiʻekiʻe: he paʻakikī kiʻekiʻe loa nā keramika alumina, ʻo ka paʻakikī Mohs he 9, ʻo ka lua wale nō i ka daimana, e kū pono ana i ke kaomi nui a me ka hopena he kūʻē kiʻekiʻe i ka haki ʻana.

Eia kekahi, kokoke ke koina o ka hoʻonui ʻana o ka thermal o nā keramika alumina i ka silicon (Si), kahi mea e kūpono ai i ka hōʻemi ʻana i ke kaumaha thermal a me ka hoʻomaikaʻi ʻana i ke kūpaʻa o ka hāmeʻa.

Ka lua,Noi maka mea substrate

Hoʻohana nui ʻia nā substrates keramika alumina i ka hana semiconductor. , ʻO kāna mau hiʻohiʻona:

1. ʻO ka hoʻokele wela maikaʻi loa: hiki i ka substrate alumina ceramic ke hoʻoili koke i ka wela i ka poho wela, e hoʻemi ana i ka mahana o ka hāmeʻa a hoʻomaikaʻi i ka pono.

2. Ikaika mechanical kiʻekiʻe: he ikaika mechanical kiʻekiʻe ka substrate alumina ceramic, hiki ke kū'ē i ka haʻalulu o waho a me ka haʻalulu, e hōʻoia i ka hana paʻa o nā mea semiconductor.

3. Hana hoʻokaʻawale kiʻekiʻe: loaʻa i ka substrate alumina ceramic ka hoʻokaʻawale uila maikaʻi, hiki ke hōʻoia i ka palekana o nā mea semiconductor i ke kaiapuni kiʻekiʻe a i ʻole ke au kiʻekiʻe.

Eia kekahi, ʻo ka substrate keramika alumina, e like mepā i hoʻopili ʻia me ka wafer chemshun 99.7% alumina, loaʻa iā ia ke kūpaʻa kemika maikaʻi a me ke kūpaʻa i ka corrosion, hiki ke hōʻoia i ka hilinaʻi o nā mea semiconductor i nā ʻano ʻino.

Ke kolu,Noi maka mea lawe ʻāpana

ʻO ka mea lawe ʻāpana seramika alumina ma ke ʻano he mea lawe ʻāpana semiconductor, nona nā ʻano penei:

1. ikaika kiʻekiʻe a me ka conductivity thermal kiʻekiʻe: hiki ke hōʻemi pono i ka mahana hana o ka chip, hoʻomaikaʻi i ke kūpaʻa a me ke ola o ka chip.

2. Hana hoʻokaʻawale kiʻekiʻe: Loaʻa i ka mea lawe ʻāpana keramika alumina ka hoʻokaʻawale uila maikaʻi, hiki ke pale i ka hoʻopilikia uila a i ʻole ka pōkole pōkole ma waena o ka ʻāpana a me nā ʻāpana ʻē aʻe.

3. ʻO ke koina o ka hoʻonui wela e kokoke ana i ko silicon (Si): he mea kūpono ia no ka hōʻemi ʻana i ke kaumaha wela a me ka hoʻomaikaʻi ʻana i ka hilinaʻi o ka chip.

He kuleana koʻikoʻi ko nā keramika alumina i ka hana semiconductor me kāna hana maikaʻi loa. Mai ka hoʻopili ʻana i nā hāmeʻa a hiki i nā mea substrate a hiki i ka mea lawe chip a pēlā aku, ua hōʻike nā keramika alumina i ka waiwai noi kiʻekiʻe. Me ka hoʻomohala mau ʻana o ka ʻoihana semiconductor, e ʻoi aku ka nui o ka hoʻohana ʻana o nā keramika alumina, e hāʻawi i ke kākoʻo ikaika no ka holomua o ka ʻoihana semiconductor. He loea ʻo Ltd. i ka hana ʻana i nā keramika alumina ʻoihana. Welina mai e hoʻokaʻaʻike mai iā mākou.
