I ka lilo ʻana o nā kaapuni i hoʻohui ʻia i ʻoihana ʻāina koʻikoʻi, ua noiʻi ʻia a hoʻomohala ʻia nā mea semiconductor he nui, a ʻo Aluminum Nitride ʻo ia kekahi o nā mea semiconductor maikaʻi loa.
Aluminum Nitride mau ano hana
Loaʻa i ka Aluminum Nitride (AlN) nā hiʻohiʻona o ka ikaika kiʻekiʻe, kiʻekiʻe ka nui resistivity, kiʻekiʻe insulation voltage, coefficient o ka hoʻonui thermal, hoʻohālikelike maikaʻi me ka silicon, a me nā mea ʻē aʻe. ma ke kahua o nā mea hoʻopili uila seramika a me nā mea hoʻopihapiha, e ulu nui nei i nā makahiki i hala iho nei, a ʻoi aku kāna hana ma mua o ka alumina. He maikaʻi ka hana holoʻokoʻa holoʻokoʻa o nā seramika Aluminum Nitride, kūpono no nā substrates semiconductor a me nā mea hoʻopihapiha hoʻopihapiha, a loaʻa iā ia ka mana hoʻohana nui i ka ʻoihana uila.
Hoʻohana i ka Aluminum Nitride
1. Nā polokalamu kelepona piezoelectric
Loaʻa i ka Aluminum Nitride ka resistivity kiʻekiʻe, ka conductivity thermal kiʻekiʻe, a me ka coefficient haʻahaʻa o ka hoʻonui e like me ke silicon, ʻo ia ka mea kūpono no nā mea uila kiʻekiʻe a me ka mana kiʻekiʻe.
2. Electronic packaging substrate materiales
ʻO Beryllium Oxide, Alumina, Silicon Nitride, a me Aluminum Nitride kekahi o nā mea maʻamau i hoʻohana ʻia no nā substrates seramika.
Ma waena o nā mea seramika i hiki ke hoʻohana ʻia e like me nā mea substrate, ʻo Silicon Nitride ceramics ka mea kiʻekiʻe kiʻekiʻe o ka flexural ikaika, maikaʻi ke pale ʻana i ka lole, a me nā ʻano mīkini piha maikaʻi loa o nā mea seramika, ʻoiai ʻo kā lākou coefficient o ka hoʻonui wela ka mea liʻiliʻi loa. Aluminum Nitride ceramics loaʻa kiʻekiʻe thermal conductivity, maikaʻi thermal haʻalulu kū'ē, a mau nō ka maikaʻi mechanical waiwai ma kiʻekiʻe wela. Hiki ke ʻōlelo ʻia, mai ka manaʻo o ka hana, ʻo Aluminum Nitride a me Silicon Nitride i kēia manawa ka mea kūpono loa no ka hoʻohana ʻana e like me nā mea hoʻopili uila uila, akā loaʻa iā lākou kahi pilikia maʻamau: kiʻekiʻe ko lākou kumukūʻai.
3. Ke noi i nā mea hoʻomāmā
Ma ke ʻano o ka hoʻololi ʻana o ka photoelectric, ua loaʻa i ka nitride aluminika (AlN) kahi bandgap semiconductor band pololei ka laulā o 6.2 eV, ʻoi aku ka kiʻekiʻe ma mua o ka indirect bandgap semiconductor. Hoʻohana ʻia ʻo AlN, ma ke ʻano he polū nui a me ka ultraviolet light-emitting material, i ka ultraviolet a me ka hohonu ultraviolet light-emitting diodes, ultraviolet laser diodes, ultraviolet detectors, etc. hoʻonā, a hiki ke hoʻololi mau ʻia ka ʻāpana o kona ʻāpana ternary a i ʻole quaternary alloy mai ka pūʻulu ʻike ʻia a i ka pūna ultraviolet hohonu, e lilo ia i mea koʻikoʻi kiʻekiʻe.
4. Hoʻohana i nā mea substrate
ʻO AlN crystal ka substrate kūpono no GaN, AlGaN, a me nā mea epitaxial AlN. Hoʻohālikelike ʻia me nā substrate sapphire a i ʻole SiC, ʻoi aku ka maikaʻi o AlN a me GaN i ka hoʻohālikelike wela a me ka hoʻohālikelike kemika, a ʻoi aku ka liʻiliʻi o ke koʻikoʻi ma waena o ka substrate a me ka papa epitaxial. No laila, hiki i nā kristal AlN e like me GaN epitaxial substrates ke hoʻohaʻahaʻa nui i ka defect density i loko o ka mea hana a hoʻomaikaʻi i kāna hana, i loaʻa kahi manaʻo maikaʻi loa o ka noi i ka hoʻomākaukau ʻana i nā mea uila uila kiʻekiʻe, kiʻekiʻe-frequency, a me ka mana kiʻekiʻe. Eia kekahi, me ka hoʻohana ʻana i nā kristal AlN ma ke ʻano he substrate material AlGaN epitaxial me nā ʻāpana alumini kiʻekiʻe (Al) hiki ke hoʻemi pono i ka defect density i ka papa epitaxial nitride a hoʻomaikaʻi nui i ka hana a me ke ola o nā mea nitride semiconductor. Ma muli o AlGaN, ua hoʻohana pono ʻia kahi mea ʻike makapō kiʻekiʻe.
5. Hoʻohana i nā seramika a me nā mea refractory
Hiki ke hoʻohana ʻia ka Aluminum Nitride i ka sintering ceramic structural; ʻO ka alumini Nitride ceramics ʻaʻole wale ʻoi aku ka maikaʻi o ka mechanical a me ka ikaika flexural ma mua o Al2O3 a me BeO ceramics, akā ʻoi aku ka kiʻekiʻe o ka paʻakikī a me ke kūpaʻa corrosion. ʻē aʻe nā ʻāpana pale-corrosion kiʻekiʻe. Eia kekahi, hiki ke hoʻohana ʻia nā seramika AlN maʻemaʻe no nā aniani aniani ʻole, me nā waiwai optical maikaʻi loa, e like me nā seramika māmā no nā mea uila uila a me nā mea hana no nā puka makani infrared kiʻekiʻe a me ka hoʻoponopono ʻana i ka pale wela.
