1.He rereke te ahua, te kaupapa me te whakamahinga o nga angiangi epitaxial me nga maramara.
I. Te ahua rereke
1, angiangi epitaxial: epitaxial angiangi e tohu ana ki tetahi kiriata karaihe kotahi i tupu i runga i te tïpako tïpako kua wera ki te pāmahana e tika ana.
2, maramara: maramara he taputapu semiconductor ahua totoka.Ko te maramara katoa ka kapi ki te kapia epoxy.
Tuarua, he rereke te kaupapa
1, angiangi epitaxial: ko te kaupapa o te angiangi epitaxial ko te taapiri i nga hiko ki te epitaxial kia pai ai te hiri me te kapi o te hua.
2, maramara: ko te kaupapa o te maramara he huri i te hiko hiko ki te hiko marama mo te rama.
E toru, nga whakamahinga rereke
1, angiangi epitaxial: epitaxial angiangi e tika ana mo te tukanga waenganui me te tukanga hoki o te maramara arahina, kahore reira, e kore e taea ki te hanga i te wherikotanga teitei wherikotanga.
2, maramara: maramara ko te rauemi matua mo te hanga rama arahina, mata LED, LED backlight.
2.He aha te maramara?
Ko te maramara he hikohiko whakauru microelectronic nui, ka taea hoki te kiia he IC;arä he putanga taiawhio kua whakaitihia ki te taumata nano (haumano o te mirimita).Ko te taha o mua o te poari ara iahiko kua taia he maha nga momo momo reo irirangi, tae atu ki nga triodes, diodes, capacitors, electrolytic, parenga, kaiwhakahaere waenga-huringa, whakawhiti, whakakaha hiko, kaitahuri, whiriwhiringa, aha atu. ko nga taiawhio kua taia me nga hononga konutai kua taia ki te papa muka waro.Ko te hua matua o te hangarau microelectronics me te whānuitanga o nga tono.Ko nga maramara kei roto i o maatau rorohiko e whakamahia ana, waea waea, hua hiko, taputapu hiko, aha atu;he maha nga wa e kiia ana e te tangata nga iahiko whakauru he maramara.
3.Ko te hanganga rawa o roto o te maramara
Ko te maramara he kupu whanui mo te hua wae hikohiko, he mea hanga mai i nga rawa hiko (te nuinga o te hiona), kei roto nga pūnga iahiko, parenga, ngongo, me nga whakawhiti.Ko te semiconductor he matū kei waenga i te kaikawe, penei i te parahi, e tere haere ai te hiko, me te insulator, ano he rapa, kaore i te kawe hiko.
