Nā hoʻohana ʻana o ka tungsten hexafluoride (WF6)

Hoʻokomo ʻia ʻo Tungsten hexafluoride (WF6) ma ka ʻili o ka wafer ma o ke kaʻina CVD, hoʻopiha i nā auwaha hoʻohui metala, a hana i ka pilina metala ma waena o nā papa.

E kamaʻilio mua kākou no ka plasma.ʻO Plasma kahi ʻano mea i haku ʻia me nā electrons manuahi a me nā ion i kau ʻia.Aia ia ma ke ao holoʻokoʻa a manaʻo pinepine ʻia ʻo ia ka ʻehā o ke ʻano o ka mea.Kapa ʻia ʻo ia ka mokuʻāina plasma, i kapa ʻia ʻo "Plasma".Loaʻa i ka plasma ka conductivity uila kiʻekiʻe a he hopena hoʻohui ikaika me ke kahua electromagnetic.He kinoea ionized hapa ia, i haku ʻia me nā electrons, nā ion, nā radical manuahi, nā ʻāpana kū ʻole, a me nā photon.ʻO ka plasma ponoʻī he hui kūʻokoʻa uila i loaʻa nā mea kino a me nā mea kemika.

ʻO ka wehewehe pololei ma lalo o ka hana o ka ikehu kiʻekiʻe, e lanakila ka mole i ka ikaika van der Waals, ka ikaika paʻa kemika a me ka ikaika Coulomb, a hōʻike i ke ʻano o ka uila kūʻokoʻa holoʻokoʻa.I ka manawa like, ʻo ka ikehu kiʻekiʻe i hāʻawi ʻia e waho e lanakila i nā mana ʻekolu i luna.ʻO ka hana, nā electrons a me nā ion e hōʻike i kahi mokuʻāina manuahi, hiki ke hoʻohana artificially ma lalo o ka modulation o kahi māla magnetic, e like me ka semiconductor etching process, CVD process, PVD a me IMP process.

He aha ka ikehu kiʻekiʻe?Ma ke kumumanaʻo, hiki ke hoʻohana ʻia ka wela kiʻekiʻe a me ka RF kiʻekiʻe.ʻO ka ʻōlelo maʻamau, ʻaneʻane hiki ʻole ke loaʻa ka wela kiʻekiʻe.He kiʻekiʻe loa kēia koi wela a kokoke paha i ka mahana o ka lā.ʻAʻole hiki ke hoʻokō i ke kaʻina hana.No laila, hoʻohana pinepine ka ʻoihana i ka RF kiʻekiʻe e hoʻokō ai.Hiki i ka Plasma RF ke kiʻekiʻe e like me 13MHz+.

Hoʻopili ʻia ʻo Tungsten hexafluoride ma lalo o ka hana o kahi māla uila, a laila waiho ʻia ka mahu e kahi māla magnetic.Ua like nā ʻātoma W me ka hulu kuisa hoʻoilo a hāʻule i lalo i ka lepo ma lalo o ka hana a ka umekaumaha.Me ka mālie, waiho ʻia nā ʻātoma W i loko o nā lua, a hoʻopiha piha ʻia i loko o nā lua e hana i nā pilina metala.Ma waho aʻe o ka waiho ʻana i nā ʻātoma W i loko o nā lua, e waiho pū ʻia lākou ma ka ʻili o ka Wafer?ʻAe, maopopo.Ma ka ʻōlelo maʻamau, hiki iā ʻoe ke hoʻohana i ke kaʻina hana W-CMP, ʻo ia ka mea a mākou e kapa ai i ke kaʻina hana wili mīkini e wehe.Ua like ia me ka hoʻohana ʻana i kahi pulumu e kahili i ka papahele ma hope o ka hau nui.Holoi ʻia ka hau ma ka honua, akā mau ka hau i loko o ka lua ma ka honua.I lalo, like like.
