molybdenum wafer molybdenum daimana pepa ma CVD

ʻO ka wehewehe pōkole:

ʻO ka helu heheʻe kiʻekiʻe o Molybdenum, ka hana wela a me ka inertness kemika e kūpono ia no nā noi CVD kahi koʻikoʻi ke kūpaʻa kiʻekiʻe o ka wela a me ke kūʻē ʻana i ka reactivity kemika. Hiki ke hoʻohana ʻia kēia mau ʻāpana no ka hana ʻana i nā mea semiconductor, nā uhi kiʻiʻoniʻoni lahilahi a me nā mea i hoʻokumu ʻia i daimana no nā ʻano ʻenehana a me nā noiʻi noiʻi.

He aha ke ʻano CVD no nā daimana?

ʻO ke ʻano o ka hoʻoheheʻe ʻana i ka mahu (CVD) o ke daimana e pili ana i ka hoʻohana ʻana i kahi kaʻina hana kemika e synthesize i kahi kiʻi daimana a i ʻole ka uhi ʻana i kahi kaiapuni i hoʻomalu ʻia. Ma kēia ʻano hana, hoʻokomo ʻia kahi hui kinoea, ka mea maʻamau i loaʻa nā kinoea hydrocarbon e like me ka methane, i loko o kahi keʻena pane me kahi mea pani e like me nā wafers molybdenum a i ʻole nā wafers daimana. Hoʻohana ʻia ke kinoea e nā ʻano like ʻole, e like me ka wela a i ʻole ka plasma, e wāwahi i nā molekala hydrocarbon a waiho i nā ʻātoma kalapona ma luna o ka substrate, e hopena i ka ulu ʻana o nā kristal daimana.

Hāʻawi ke kaʻina hana CVD o daimana i nā pono he nui, me ka hiki ke hana i nā pale daimana kiʻekiʻe me ka mana pololei o ka mānoanoa, ka like a me ka haku mele. ʻAe ia i ka waiho ʻana o nā kiʻi daimana ma nā ʻano mea substrate like ʻole, hiki ke hana i nā ʻāpana i uhi ʻia i daimana no nā ʻano ʻenehana a me nā noiʻi noiʻi.

Ma ke ʻano holoʻokoʻa, ʻo ke ʻano CVD o daimana he ʻano hana maʻamau a hoʻohana nui ʻia no ka hana ʻana i nā kiʻi ʻoniʻoni daimana synthetic a me nā uhi me nā waiwai i hana ʻia, e hoʻolilo iā lākou i mea waiwai i nā ʻoihana e like me ka uila, nā mea ʻoki ʻoki, a me nā lole pale pale.

He aha ka paʻakikī o ka uhi CVD?

Hiki ke ʻokoʻa ka paʻakikī o ka hoʻoheheʻe ʻana i ka mahu (CVD) ma muli o nā mea kikoʻī i waiho ʻia a me nā ʻāpana hana i hoʻohana ʻia. Eia nō naʻe, ʻike ʻia nā pale CVD no ko lākou ʻano paʻakikī, ʻoi aku ma mua o ko nā uhi hoʻoheheʻe kino kino (PVD).

No nā pale daimana CVD, ʻoi aku ka nui o ka paʻakikī. ʻO ka daimana kekahi o nā mea paʻakikī loa i ʻike ʻia, a ʻo nā uhi daimana CVD he ʻoi aku ka paʻakikī i ʻoi aku ma mua o nā ʻano o nā ʻano pale. ʻO ka paʻakikī o nā uhi daimana CVD e ana maʻamau me ka hoʻohana ʻana i ka paʻakikī paʻakikī Vickers a mai 8000 HV a ʻoi aku ma luna o 10000 HV, e lilo ia i mea paʻakikī a paʻakikī loa.

No nā'āpana CVD'ē a'e, e like me ka carbide a i'ole ka nitride-based coatings, hiki ke ki'eki'e ka pa'akikī, e hā'awi ana i ka pale lole maika'i a me ka lō'ihi i nā'ano hana'oihana.

Ma ke ʻano holoʻokoʻa, waiwai ʻia nā uhi CVD no ko lākou paʻakikī ʻokoʻa, e kūpono ana iā lākou no nā noi kahi e hoʻopaʻa ʻia ai ke kūpaʻa, ke kūpaʻa kiʻekiʻe, a me ka hana lōʻihi.
