Nekukurumidza kusimudzira kweindasitiri yepasirese semiconductor, maitiro ekugadzira chip apinda zvizere munguva yenanometer. Mune iyi yakanyatso kugadzirwa maitiro, chero miniti kushanduka kwezvakatipoteredza kana kusachena kwezvinhu kunogona kutungamira mukukweshwa kwebatch rese rewafers. Naizvozvo, magetsi ehunyanzvi magasi uye akanyanya-kuchena magasi emaindasitiri anoita basa risingadzokerike. Pakati pavo, high kuchena mvura argon rave chinhu chakakosha chinodyiwa mukushanda kwezuva nezuva kwema semiconductor machira nekuda kweyekupedzisira makemikari inertness uye yakanaka yemuviri zvimiro.

Ichi chinyorwa chinozoongorora zvakadzama mashandisirwo emvura argon mukugadzira chip maitiro uye nekupa dhizaini rekutenga dhairekitori rezvikwata zvemabhizinesi ekutengesa.

Core Zvishandiso: Nei Liquid Argon Isingaparadzaniswi kubva kuSemiconductor Kugadzira?

MuFront-End-of-Line (FEOL) semiconductor yekugadzira maitiro, liquid argon yemasemiconductors inonyanya kuiswa mumatanho anotevera epakati anotaridza goho rechigadzirwa:

• Physical Vapor Deposition (PVD) / Sputtering: Ultra-pure argon gasi, yakaumbwa negasi yemvura argon, ndiyo inonyanya kushanda gasi muPVD sputtering process. Mukamuri yevacuum, maargon ions anokwidziridzwa nemunda wemagetsi kubhomba zvinhu zvakanangwa, zvichiita kuti maatomu anonangwa abviswe uye aise zvakaenzana pawafer kuti agadzire firimu resimbi. Kuchena kwepamusoro chinhu chinodiwa kuti ive nechokwadi chekuwanda uye kuenderana kwemagetsi kwefirimu.

• Yakanyatsochengeteka Inert Inodzivirira Atmosphere: Munguva yekudhonza monocrystalline silicon (yakadai seCzochralski process) uye yakakwirira-tembiricha annealing maitiro, silicon inopindirana nyore neokisijeni pakupisa kwakanyanya. Naizvozvo, argon gasi inofanirwa kugara ichiunzwa kutsiva mhepo, ichipa nharaunda inert yakakwana yakaparadzaniswa neokisijeni uye mwando, nekudaro ichiva nechokwadi chekukura kwakakwana kwesilicon crystal lattice.

• Cryogenics uye Wafer Yekuchenesa Tekinoroji: Mumaitiro epamberi akadai seExtreme Ultraviolet (EUV) lithography, iyo yekupedzisira-yakaderera tembiricha yemvura argon (inofashaira nzvimbo -186°C) dzimwe nguva inoiswa kune inotonhodza masisitimu emidziyo chaiyo. Panguva imwe chete, argon aerosol tekinoroji inoshandiswawo kunanometer-chiyero chemuviri chidiki-yekuchenesa pane wafer nzvimbo, iyo inogona kusabvisa-inoparadza kubvisa maminetsi echinhu.

Hunhu Hwunotema Goho: Iwo Mamiriro Akasimba ePamusoro-Kuchena Liquid Argon

Iyo semiconductor indasitiri yezvinodiwa zvezvakagadzirwa zvakakasharara. Zvakajairwa maindasitiri-giredhi yemvura argon kazhinji inongoda kusvika pakuchena kwe99.9% kana 99.99%, asi izvi zviri kure nekuzadzisa zvinodiwa zvekugadzira chip. For vanokwanisa yakakwirira kuchena mvura argon, kuchena kwekutanga kunodiwa kuti isvike 99.999% (5N), uye mumanode epamusoro, inotoda kusvika 99.9999% (6N) kana kupfuura.

Chinonyanya kukosha ndechekudzora kusachena. Zvirimo zveokisijeni, nitrogen, mwando, mahydrocarbon akazara (THC), uye trace metal ions zvinofanirwa kudzorwa zvakanyanya pappb (zvikamu pabhirioni) kana kunyange ppt (zvikamu patiririyoni). Kunyangwe kana imwe miniti yetsvina yakasanganiswa mupombi yegasi, inoumba micro-defects pane wafer pamusoro, zvichikonzera chip mapfupi maseketi kana kudonha kwazvino, kudonhedza pasi mwero wegoho uye kuunza kurasikirwa kukuru kwehupfumi.

Procurement Guide: Maitiro ekuongorora uye kusarudza Nyanzvi Liquid Argon Supplier?

Tichifunga nezvekuita basa repamusoro-kuchena magasi mukushanda kwemitsara yekugadzira, kutsvaga nekuchengetedza anonyatso kwanisa uye anokwanisa mvura argon mutengesi ibasa rekutanga rekutenga nekutengesa cheni zvikwata. Paunenge uchiongorora vangangove vatengesi, zvinokurudzirwa kutarisa pane zvinotevera zviyero zvitatu:

Yakasimba Hunhu Kudzora uye Kuedza Kugona: Vatengesi vakanaka vanofanirwa kuve vakashongedzerwa nepamusoro-tier trace yekuongorora michina yakadai seGasi Chromatographs (GC) uye Mass Spectrometers (MS). Vanofanira kukwanisa kupa COA yakadzama (Chitupa cheKuongorora) chebatch yega yega kuti ive nechokwadi chekuenderana mukuchena pakati pekutakura.

Yakasimba Yekugovera Chain Resilience uye Delivery Kugadzikana: Machira anowanzo shanda 24/7/365, uye mutengo wepasi-nguva wakakwira zvakanyanya. Naizvozvo, vatengesi vanofanirwa kuve nehukuru hwenzvimbo yekuchengetedza mvura, ngarava yavo ye cryogenic tanker marori, uye yakazara contingency hurongwa hwekuvimbisa kwe emergency.

Yepamberi Containers uye Anti- "Secondary Kusvibiswa" Tekinoroji: Hazvina mhosva kuti kuchena kwegesi kwakakwirira sei, hazvina maturo kana yakasvibiswa panguva yekufambisa. Iyo inotarisisa inofanirwa kunge iri pane emutengesi's cryogenic kuchengetedza matangi uye tanker yemukati madziro ekurapa tekinoroji (senge yakamboitwa Electropolishing/EP kurapwa), pamwe neStandard Operating Procedures (SOP) yevhavha uye pombi yekuchenesa panguva yekuzadza uye kutamisa matanho, kuve nechokwadi chekuti kuchena kwakanyanya kunogona kuendeswa zvakananga kubva kuchirimwa kuenda kumutengi.

Mhedziso

Pasi pekuenderera mberi kwekufambira mberi kweMutemo waMoore, yakakwira kuchena kwemvura argon haingori chinhu chinobatika, asiwo "isingaonekwe escort" yepamberi semiconductor maitiro. Kuongorora nekusarudza nesainzi a liquid argon mutengesi iine simba rakazara rekuona iyo yepamusoro-mhando uye yakagadzikana yekupihwa kwemvura argon kune semiconductors ndiyo yakakosha yekona yeese semiconductor yekugadzira bhizinesi kuvandudza maitiro egoho uye kuhwina mumakwikwi emusika wepasi rose.
