ʻO ka hoʻopilikino pono ʻana o ke kumu alakaʻi

ʻO ka papa alakaʻi IC he ʻenehana hana papa kaapuni paʻi e hoʻopili ai i nā uwea a me nā ʻāpana uila ma o ke alakaʻi metala.Hoʻohana nui ʻia kēia ʻenehana i ka hana ʻana i nā ʻāpana hoʻohui (IC) a me nā papa kaapuni paʻi i nā mea uila.E hoʻolauna kēia ʻatikala i ka noi a me nā pono o nā papa alakaʻi IC, a e ʻimi i ka noi a me ka hoʻohana ʻana i ka photolithography i ka hana ʻana i ka papa alakaʻi IC a me nā mea i hoʻohana ʻia.

ʻO ka mea mua, ʻo ka ʻenehana alakaʻi IC kahi ʻenehana maikaʻi loa e hiki ke hoʻomaikaʻi nui i ka paʻa a me ka hilinaʻi o nā mea uila.Ma ka hana IC, ʻo nā papa alakaʻi he ala pili uila hilinaʻi e hōʻoia i ka pili pono ʻana o nā mea uila ma ka papa kaapuni i ka chip nui.Eia kekahi, hiki i nā papa alakaʻi IC ke hoʻomaikaʻi i ka hilinaʻi o nā papa kaapuni no ka mea hiki iā lākou ke hana i nā papa kaapuni i ʻoi aku ka ikaika mechanical a ʻoi aku ka maikaʻi o ka corrosion.

ʻO ka lua, ʻo ka photolithography kahi ʻenehana maʻamau no ka hana ʻana i nā papa alakaʻi IC.Hoʻokumu ʻia kēia ʻenehana i ke kaʻina photolithography, ka mea e hana ana i nā papa alakaʻi ma o ka wehe ʻana i nā kiʻi ʻoniʻoni ʻoniʻoni metala i ka mālamalama a laila hoʻopaʻa ʻia me kahi hopena kemika.Loaʻa i ka ʻenehana Photolithography nā mea maikaʻi o ka precision kiʻekiʻe, ka maikaʻi kiʻekiʻe, a me ke kumu kūʻai haʻahaʻa, no laila ua hoʻohana nui ʻia ia i ka hana ʻana i ke alakaʻi IC.

I ka hana ʻana o ke kumu alakaʻi IC, ʻo ka mea nui i hoʻohana ʻia he kiʻi ʻoniʻoni metala.Hiki ke keleawe, aluminika, a gula paha, a me nā mea ʻē aʻe.Hoʻomākaukau ʻia kēia mau kiʻi ʻoniʻoni ʻoniʻoni metala e nā ʻenehana hoʻoheheʻe kino kino (PVD) a i ʻole nā ​​ʻenehana hoʻoheheʻe kino (CVD).I ka hana ʻana i ka pahu alakaʻi IC, ua uhi ʻia kēia mau kiʻi ʻoniʻoni metala ma ka papa kaapuni a laila kālai ʻia e ka ʻenehana photolithography e hana i nā papa alakaʻi maikaʻi.

I ka hopena, he kuleana koʻikoʻi ka ʻenehana alakaʻi alakaʻi IC i nā polokalamu uila hou.Ma ka hoʻohana ʻana i ka ʻenehana photolithography a me nā mea kiʻiʻoniʻoni ʻoniʻoni metala, hiki ke hana ʻia nā papa alakaʻi kiʻekiʻe, kiʻekiʻe kiʻekiʻe, a me nā kumu kūʻai.ʻO ka maikaʻi o kēia ʻenehana ʻo ia ka hiki ke hoʻomaikaʻi i ka hilinaʻi a me ka paʻa o nā mea uila, a laila e hāʻawi i ka hoʻomohala ʻana i ka ʻenehana uila hou.
