He aha ka SEMICONDUCTOR?
ʻO ka mea semiconductor kahi mea uila e hoʻohana ana i ka hoʻokele uila akā loaʻa nā ʻano i waena o ka mea hoʻokele, e like me ke keleawe, a me ka insulator, e like me ke aniani.Ke hoʻohana nei kēia mau mea hana i ka hoʻokele uila i loko o ke kūlana paʻa e kūʻē i ke kūlana kinoea a i ʻole ka thermionic emission i loko o kahi ʻūhā, a ua hoʻololi lākou i nā paipu māmā i ka hapa nui o nā noi hou.
ʻO ka hoʻohana maʻamau o nā semiconductor i loko o nā pahu kaapuni hoʻohui.ʻO kā mākou mau mea hoʻopili helu hou, me nā kelepona paʻa a me nā papa, aia paha nā piliona o nā semiconductors liʻiliʻi i hui pū ʻia ma nā pahu hoʻokahi i hoʻopili ʻia ma kahi wafer semiconductor hoʻokahi.
Hiki ke hoʻololi ʻia ka conductivity o kahi semiconductor ma nā ʻano like ʻole, e like me ka hoʻokomo ʻana i kahi pā uila a i ʻole ka mākēneki, ma ka wehe ʻana iā ia i ka mālamalama a i ʻole ka wela, a i ʻole ma muli o ka hoʻololi ʻana i ka mīkini o kahi doped monocrystalline silicon grid.ʻOiai he kikoʻī kikoʻī ka wehewehe ʻenehana, ʻo ka manipulation o semiconductors ka mea i hiki ai i kā mākou hoʻololi kikohoʻe i kēia manawa.
Pehea ka hoʻohana ʻana o ka alumini ma nā semiconductors?
He nui nā waiwai o ka alumini e lilo ia i koho mua no ka hoʻohana ʻana i nā semiconductors a me nā microchips.No ka laʻana, ʻoi aku ka maikaʻi o ka alumini i ka silicon dioxide, kahi mea nui o semiconductors (ʻo ia kahi i loaʻa ai ka inoa ʻo Silicon Valley).ʻO ia nā waiwai uila, ʻo ia hoʻi ka haʻahaʻa haʻahaʻa o ka uila a hana maikaʻi no ka hoʻopili ʻana me nā kaula uea, ʻo ia kekahi pono o ka alumini.ʻO ka mea nui hoʻi he maʻalahi ke kūkulu ʻana i ka alumini i nā kaʻina etch maloʻo, kahi hana koʻikoʻi i ka hana ʻana i nā semiconductor.ʻOiai nā metala ʻē aʻe, e like me ke keleawe a me ke kālā, hāʻawi ʻoi aku ka maikaʻi o ka corrosion a me ka paʻakikī uila, ʻoi aku ka maikaʻi ma mua o ka alumini.
ʻO kekahi o nā noi nui loa no ka alumini i ka hana ʻana i nā semiconductors i ke kaʻina o ka ʻenehana sputtering.Hoʻokō ʻia ka ʻāpana lahilahi o nā mānoanoa nano o nā metala maʻemaʻe kiʻekiʻe a me ke silika i nā wafers microprocessor ma o ke kaʻina hana o ka hoʻoheheʻe kino kino i kapa ʻia ʻo sputtering.Hoʻokuʻu ʻia nā mea mai kahi pahu hopu a waiho ʻia ma kahi ʻāpana substrate o ke silikoni i loko o kahi keʻena maloʻo i hoʻopiha ʻia me ke kinoea e kōkua i ke kaʻina hana;ʻO ka maʻamau he kinoea inert e like me argon.
ʻO nā papa kākoʻo no kēia mau pahuhopu i hana ʻia me ka alumini me nā mea maʻemaʻe kiʻekiʻe no ka waiho ʻana, e like me tantalum, keleawe, titanium, tungsten a i ʻole 99.9999% alumini maʻemaʻe, i hoʻopaʻa ʻia i ko lākou ʻili.Hoʻokumu ʻia ke kiʻi kiʻi kiʻi kiʻi kiʻi a i ʻole kemika o ka ʻili conductive o ka substrate i nā ʻōnaehana kaapuni microscopic i hoʻohana ʻia i ka hana a ka semiconductor.
ʻO ka alumini alumini maʻamau i ka hana semiconductor ʻo 6061. No ka hōʻoia ʻana i ka hana maikaʻi loa o ka alloy, ma ke ʻano maʻamau e hoʻopili ʻia kahi papa anodized pale i ka ʻili o ka metala, kahi e hoʻonui ai i ka pale ʻana i ka corrosion.
No ka mea ʻo ia nā mea pono kūpono, pono e nānā pono ʻia ka corrosion a me nā pilikia ʻē aʻe.Ua ʻike ʻia kekahi mau mea e kōkua ai i ka corrosion i nā mea semiconductor, no ka laʻana i ka hoʻopili ʻana iā lākou i loko o ka plastic.
