ʻO ke kūlana hoʻohana i kēia manawa o ka uhi semiconductor vacuum

E like me kā mākou ʻike, ʻo ka wehewehe ʻana o ka semiconductor he conductivity ma waena o nā conductors maloʻo a me nā insulators, resistivity ma waena o ka metala a me ka insulator, ʻo ia ka mea maʻamau i ka lumi wela i loko o ka laulā o 1mΩ-cm ~ 1GΩ-cm. nā mea hana, nā mea uila a me nā hana hoʻomohala ʻē aʻe. He kuleana koʻikoʻi ka uhi semiconductor vacuum.

Hōʻike ʻia nā semiconductor e ko lākou mau hiʻohiʻona intrinsic, ka mahana a me ka ʻike haumia. Hoʻokaʻawale ʻia nā mea hoʻoheheʻe semiconductor vacuum mai kekahi i kekahi ma muli o kāna mau mea hoʻohui. Hoʻokumu ʻia nā mea a pau ma luna o ka boron, carbon, silicon, germanium, arsenic, antimony, tellurium, iodine, etc., a me kekahi mau GaP, GaAs, lnSb, etc.

ʻO ka hoʻoheheʻe ʻana i ka ʻūhā, ka uhi ʻana i ka sputtering, ka uhi ion a me nā mea hana ʻē aʻe hiki ke hana i ka uhi semiconductor. ʻOkoʻa kēia mau mea hoʻopili i kā lākou hana hana, akā hana lākou a pau i ka semiconductor material coating material i waiho ʻia ma ka substrate, a ma ke ʻano he mea o ka substrate, ʻaʻohe koi, hiki ke lilo i semiconductor a i ʻole. Eia kekahi, hiki ke hoʻomākaukau ʻia nā uhi me nā ʻano uila like ʻole a me ka optical e ka diffusion haumia a me ka implantation ion ma ka ʻili o ka substrate semiconductor i kahi ākea. Hiki ke hana ʻia ka ʻāpana lahilahi e like me ka uhi semiconductor ma ka laulā.

ʻO ka uhi ʻana i ka semiconductor vacuum he mea nui ia i ka uila inā paha no nā mea hana a i ʻole passive. Me ka hoʻomau mau ʻana o ka ʻenehana uhi semiconductor coating, hiki ke hoʻokele pololei i ka hana kiʻiʻoniʻoni.

I nā makahiki i hala iho nei, ua holomua wikiwiki ka uhi amorphous a me ka uhi polycrystalline i ka hana ʻana i nā mea paʻi kiʻi kiʻi kiʻi, nā paipu hopena i hoʻopili ʻia, a me nā pūnaewele solar kiʻekiʻe. Eia kekahi, ma muli o ka hoʻomohala ʻana o ka uhi semiconductor vacuum a me ke kiʻi ʻoniʻoni ʻoniʻoni o nā mea ʻike, kahi e hōʻemi nui ai i ka paʻakikī o ke koho ʻana i nā mea a me ka hoʻomaʻamaʻa ʻana i ke kaʻina hana. Ua lilo nā lako hoʻoheheʻe semiconductor i mea pono no nā noi semiconductor. Hoʻohana nui ʻia nā mea hana no ka uhi ʻana i ka semiconductor o nā mea kāmela, nā pūnaewele lā, nā transistors i uhi ʻia, ka hoʻokuʻu ʻana o ka māla, ka kukui cathode, ka hoʻokuʻu electron, nā mea ʻike kiʻi ʻoniʻoni, etc.

Hoʻolālā ʻia ka laina hoʻoheheʻe magnetron sputtering me kahi ʻōnaehana hoʻokele piha piha, kahi pānaʻi hoʻopā kanaka-machine maʻalahi a intuitive. Hoʻolālā ʻia ka laina me kahi papa hana piha e hoʻokō i ka nānā piha ʻana i ke kūlana hana no nā ʻāpana laina hana holoʻokoʻa, ka hoʻonohonoho hoʻonohonoho hoʻonohonoho kaʻina, ka pale hana a me nā hana alarm. ʻO ka ʻōnaehana uila holoʻokoʻa palekana, hilinaʻi a paʻa. Hoʻolako ʻia me luna a me lalo ʻelua ʻaoʻao magnetron sputtering target a i ʻole ʻōnaehana pale ʻaoʻao hoʻokahi.

Hoʻohana nui ʻia nā mea hana i nā papa kaapuni seramika, chip high-voltage capacitors a me nā pani pani ʻē aʻe, ʻo nā wahi noi nui nā papa uila uila.
