I te tere o te whanaketanga o te umanga haurua-ira, kua tere te piki haere o te tauine o te umanga, ā, kei te whanake tonu ngā taputapu hanga haurua-ira ki te tika me te uaua. Nā te mea he pai ngā painga o ngā uku ki te pakeke teitei, te modulus elastic teitei, te ātete kakahu teitei, te whakamarumaru teitei, te ātete waikura, te iti o te whānui, me ētahi atu, ka taea te whakamahi hei wāhanga o te mīhini whakakanapa silicon, taputapu maimoatanga wera epitaxial/waikura/horapa, mīhini lithography, taputapu whakatakotoranga, taputapu whakairo haurua-ira, mīhini whakauru katote me ētahi atu taputapu, nō reira ko te rangahau me te whanaketanga me te hanga o ngā wāhanga uku tino tika ka pā tika ki te whanaketanga o te umanga haurua-ira. Kei te piki haere ngā whakaritenga hangarau mō tōna whakaritenga.
Alumina parakore teitei, 99.7%-99.9% alumina.
He kaha miihini teitei, he ātete kakahu teitei, he ārai hiko teitei, he pumau matū teitei, he ātete wera pai me te ātete waikura. I tēnei wā, ko te whakamahinga o te kōpae huri uku, te papa silicon semiconductor, te tikanga huri tino pai me te hou. Ka whakamahia te tukanga huri taha-rua hei huri i te papa silicon kua tapahia, ā, ka whakapai ake i te kounga o te papa huri mā te whakapai ake i te tukanga huri (rauemi kōpae, wai huri, pēhanga huri me te tere huri, me ētahi atu). Ina koa, ko te whakamahinga o ngā pereti uku hei utu mō ngā pereti rino maka, hei karo i te huri i te mata matua o te papa i puta mai i ngā whara, i te parahanga rānei, ka whakaiti i te whakaurunga o ngā katote konganuku, ka taea te whakaiti i te tukatuka o muri mai o te silicon, ka whakapoto i te wā tukanga (waikura) e whai ake nei, ka whakapai ake i te pai o te whakaputa, ka whakaiti i te ngaronga o te tukatuka silicon, ka tino whakapai ake i te whakamahinga o te silicon.
Pereti whakakanapa wafer alumina teiteie whakamahia ana i roto i ngā ahumahi haurua-ira, hinu, matū, photovoltaic, karaihe wai me ētahi atu ahumahi, pērā i ngā wāhanga mīhini, ngā wāhanga hiko, te kōpae whakapūngao ngaruiti, ngā rauemi whakamahana me ētahi atu wāhanga, ngā taputapu haurua-ira, ngā taputapu korehau, ngā taputapu hanga karaihe wai me ētahi atu wāhanga. He mea nui te whakamahinga o ngā uku alumina rahi nui me te tino parakore i roto i te ahumahi hapaira me te ahumahi maramara haurua-ira. He tautoko matua me te pau mō te whakakanapa matū miihini (CMP) o ngā anga hapaira me ngā anga silicon haurua-ira. Ka taea hoki te whakamahi i ngā uku alumina rahi nui me te tino parakore hei papa alumina mō te LCD.
