SEMICONDUCTOR
Kedu ihe bụ SEMICONDUCTOR?
Ngwa semiconductor bụ ihe eletrọnịkị nke na-eji ntugharị eletriki mana nwere àgwà dị n'etiti nke onye nduzi, dịka ọla kọpa, na nke insulator, dị ka iko.Ngwa ndị a na-eji ọkụ eletrik na steeti siri ike na-emegide ikuku gas ma ọ bụ ikuku thermionic n'ime oghere, ha edochiela tubes na-ekpo ọkụ n'ọtụtụ ngwa ọgbara ọhụrụ.
Ihe kacha eji semiconductor eme ihe bụ na ibe sekit agbakwunyere.Ngwa mgbako ọgbara ọhụrụ anyị, gụnyere ekwentị mkpanaaka na mbadamba, nwere ike ịnwe ijeri obere semiconductor jikọtara na otu ibe ha niile jikọtara na otu semiconductor wafer.
Enwere ike ịmegharị conductivity nke semiconductor n'ụzọ dị iche iche, dị ka site na iwebata ọkụ eletrik ma ọ bụ magnetik, site n'ikpughe ya na ọkụ ma ọ bụ okpomọkụ, ma ọ bụ n'ihi nrụrụ igwe nke grid monocrystalline silicon doped.Ọ bụ ezie na nkọwa teknụzụ zuru oke, njikwa nke semiconductor bụ ihe mere mgbanwe dijitalụ anyị ugbu a kwe omume.
Kedu otu esi eji aluminom na semiconductors?
Aluminom nwere ọtụtụ ihe na-eme ka ọ bụrụ nhọrọ bụ isi maka iji na semiconductor na microchips.Dịka ọmụmaatụ, aluminom nwere njikọ dị elu na silicon dioxide, akụkụ bụ isi nke semiconductor (nke a bụ ebe Silicon Valley nwetara aha ya).Ọ bụ ihe ọkụ eletrik, ya bụ na ọ nwere nguzogide eletrik dị ala ma na-eme ka ọ bụrụ ezigbo kọntaktị na njikọ waya, bụ uru ọzọ nke aluminom.Ihe dịkwa mkpa bụ na ọ dị mfe ịhazi aluminom na usoro etch akọrọ, nzọụkwụ dị mkpa na ịme semiconductor.Ọ bụ ezie na ọla ndị ọzọ, dị ka ọla kọpa na ọlaọcha, na-enye nguzogide corrosion ka mma na ike eletriki, ha dịkwa oke ọnụ karịa aluminum.
Otu n'ime ngwa kachasị ewu ewu maka aluminom na mmepụta nke semiconductor bụ usoro nke teknụzụ sputtering.A na-arụzu obere oyi akwa nke nano ọkpụrụkpụ nke ọla ndị dị oke ọcha na silicon na microprocessor wafers site na usoro ntinye ikuku anụ ahụ mara dị ka sputtering.A na-ewepụ ihe site na ebumnuche ma tinye ya na akwa mkpuchi silicon n'ime oghere oghere nke jupụtara na gas iji nyere aka mee ka usoro ahụ dị mfe;na-abụkarị gas inert dị ka argon.
A na-eji aluminom mee efere nkwado maka ebumnuche ndị a nke nwere nnukwu ihe dị ọcha maka ntinye, dị ka tantalum, ọla kọpa, titanium, tungsten ma ọ bụ 99.9999% aluminom dị ọcha, jikọtara n'elu ha.Igwe ọkụ ma ọ bụ kemịkalụ etching nke ala na-eduzi mkpụrụ na-emepụta ụkpụrụ sekit microscopic ejiri na ọrụ semiconductor.
Ihe na-emekarị aluminum alloy na nhazi semiconductor bụ 6061. Iji hụ na arụmọrụ kachasị mma nke alloy ahụ, n'ozuzu, a ga-etinye oyi akwa anodized na-echebe n'elu igwe, nke ga-eme ka nkwụsị nke corrosion dịkwuo elu.
N'ihi na ha bụ ngwaọrụ ndị ziri ezi, corrosion na nsogbu ndị ọzọ ga-enyocha nke ọma.Achọpụtala ọtụtụ ihe na-enye aka na corrosion na ngwaọrụ semiconductor, dịka ọmụmaatụ ịkwakọ ha na rọba.
