I. Ntchito Zazikulu ndi Ntchito za Molybdenum
Molybdenum ndi siliva-yoyera yoyera yokhala ndi mawonekedwe owoneka bwino komanso makemikolo, kupangitsa kuti igwiritsidwe ntchito kwambiri m'malo osiyanasiyana. Zotsatirazi ndizomwe zimagwiritsidwa ntchito ndi ntchito za molybdenum:
1. Makampani a Zitsulo: Molybdenum imayang'anira mafakitale azitsulo, omwe amawerengera pafupifupi 80% ya mowa wonse wa molybdenum. Imawonjezera mphamvu yachitsulo, kulimba, kukana kuvala, komanso kukana dzimbiri, zomwe zimapangitsa kuti zigwire bwino ntchito komanso moyo wautali wautumiki. Mwachitsanzo, molybdenum-yokhala ndi zitsulo zosapanga dzimbiri imagwiritsidwa ntchito kwambiri m'malo ochita dzimbiri monga mafakitale a mankhwala ndi zam'madzi.
2. Makampani a Chemical: Mankhwala a Molybdenum amagwiritsidwa ntchito kwambiri ngati chothandizira pamakampani opanga mankhwala. Mwachitsanzo, molybdenum disulfide ingagwiritsidwe ntchito ngati chothandizira hydrodesulfurization ndi hydrocarbon cracking, pamene molybdenum oxide amagwiritsidwa ntchito popanga mitundu yosiyanasiyana ya inki ndi utoto.
3. Zamagetsi Zamagetsi: Molybdenum imagwiritsidwa ntchito ngati ma elekitirodi pamakampani opanga zamagetsi. Chifukwa cha -kukhazikika kwake kwa kutentha komanso kusinthasintha kwamagetsi kwabwino, ma elekitirodi a molybdenum amagwiritsidwa ntchito kwambiri pazida zamagetsi monga ma electron chubu, transistors, ndi rectifiers. Molybdenum imagwiritsidwanso ntchito popanga zinthu zotenthetsera ndi zishango za kutentha m'ng'anjo za vacuum.
II. Njira Zofunikira Zogwiritsira Ntchito Molybdenum mu Semiconductor Manufacturing
Ndi kupita patsogolo kofulumira kwaukadaulo wa semiconductor, kugwiritsa ntchito molybdenum m'gawoli kwafalikira kwambiri. Zotsatirazi ndi njira zitatu zazikulu zogwiritsira ntchito molybdenum popanga semiconductor:
1. Kuyika kwa ion: Pochita izi, molybdenum imagwiritsidwa ntchito ngati gwero la ayoni. Kuyika kwa ion ndi njira yokhazikitsira ma atomu a dopant mu zowotcha za silicon, zomwe zimatha kusintha mawonekedwe a wafer. Chifukwa cha malo ake osungunuka kwambiri komanso kukana kwa dzimbiri, molybdenum imatha kupirira momwe mpweya wa dopant ndi kukokoloka kwa plasma mkati mwa chipindacho, motero kuwonetsetsa kukhazikika ndi mphamvu ya kuyika kwa ion.
2. Zipangizo za Molecular beam epitaxy: Molecular beam epitaxy ndiukadaulo-wolondola kwambiri,{2}}wapamwamba kwambiri wa semiconductor kukula. Pochita izi, molybdenum imagwiritsidwa ntchito ngati zida za baffles, zosungira gawo lapansi, ndi zigawo zina mkati mwa chipinda chopumuliramo. Chifukwa cha kuuma kwake kwakukulu komanso kusalala, molybdenum imatsimikizira kulondola komanso kusasinthika kwa kapangidwe ka semiconductor crystal.
3. Masks a Photolithography: Panthawi yojambula zithunzi, chinthu chimagwiritsidwa ntchito ngati chigoba kuti chiteteze madera ena pa silicon wafer kuchokera ku photoresist. Chojambula cha Molybdenum chimagwiritsidwa ntchito kwambiri ngati chigoba cha photolithography chifukwa cha kulondola kwambiri, kubwerezabwereza, komanso kukana kwa dzimbiri.
