Sei Masisitimu Ekuendesa Gas eUHP Ari Akakosha Zvikuru?
Mukugadzira ma semiconductor—maitiro akadai se etching, CVD, ion implantation, uye lithography—magasi e process anofanira kunge akachena zvakanyanya, kazhinji 99.9999% (6N) kana kunyange 99.99999% (7N). Kunyangwe tsvina shoma pa ppb (zvikamu pa bhiriyoni) kana ppt (zvikamu pa trillion)—senge hunyoro kana oxygen—zvinogona kukonzera zvikanganiso zvinouraya senge gate oxide thinning, metallic voids, kana short circuits pama wafers, zvichikonzera kupwanyika kwenzvimbo dzese.
Saka basa reUHP gas delivery system nderekutakura magasi kubva kunobva gasi kuenda kuchinhu chekugadzirisa pasina kusvibiswa, kudzivirira kusvibiswa uye kubuda kwemvura panzvimbo imwe neimwe.
Sei EP Tubing Ichiva Mutsipa weUHP Systems?
Machubhu eEP (Electropolished) anogadzirwa nesimbi isingatsvedzeri iyo inopetwa nemagetsi, zvichiita kuti mukati muite segirazi. Izvi zvinoita kuti ive "tsinga" inokosha pakuparadzirwa kwegasi reUHP.
Kuchena Kwepamusoro - Kudzivirira Panobva
Kugadziriswa kweEP kunoderedza kuomarara kwemukati meganda (Ra) kusvika pa 0.13 µm - 0.25 µm kana kudzika. Kupera uku kwakapfava kunobvisa matombo madiki diki nenzvimbo dzinonyungudika, zvichisiya nzvimbo yekuti zvidimbu, maayoni esimbi, kana hunyoro zvinamire.
Kuramba Kuora Kwakawedzerwa - Kuchengetedza Kuchena
Danho re electropolishing rinobvisa tsvina pamusoro pevhu uye rinogadzira layer isina kusvibiswa ine chrome-oxide yakawanda, zvichivandudza zvakanyanya kupesana nemagasi anoparadza akadai seCl₂, CF₄, uye HCl. Izvi zvinodzivirira ngura yemadziro emapaipi inogona kugadzira tunhu tudiki kana kusvibiswa negasi.
Kubudirira Kwekuyerera Kwakavandudzwa uye Kukurumidza Kubvisa Mvura
Rusvingo rwemukati rwakatsetseka runoderedza kuramba kwemvura uye runokurumidza kucheneswa kwesisitimu uye kuchinjana negasi. Muzviitiko zvinoda kuchinjana negasi nekukurumidza, izvi zvinopfupisa nguva yekutenderera uye zvinowedzera simba remagetsi.
Zvinhu Zvepamusoro - "Korona" Standard
Machubhu eEP emhando yepamusoro anogadzirwa nesimbi isingatsvedzeri ye316L VIM-VAR (Vacuum Induction Melting + Vacuum Arc Remelting). Maitiro aya ekunyungudutsa kaviri anoita kuti simbi yesimbi ive yakachena zvakanyanya, inova ndiyo chinhu chikuru chinodiwa kuti EP ibudirire.
Maitiro Ekushandisa Kiyi
•
Maitiro Epakati- Kuendeswa kwemagasi akachena kwazvo anoshandiswa pakuchenesa, CVD, ion implantation, uye lithography.
•
Magasi Akakosha– Kubata zvakachengeteka magasi anobvira, ane chepfu, kana anoparadza akadai seSiH₄, PH₃, Cl₂, uye BCl₃. Kune magasi ane njodzi huru, machubhu eEP ane containment mbiri anowanzo shandiswa (chubhu yemukati yegasi, jaketi rekunze rinobviswa kana kucheneswa nenitrogen kuti rionekwe kana richibuda).
•
Zvishandiso Zvakakosha- Inoshandiswa mumapaneru ekugovera gasi (VMBs), makabati egasi, uye mahoko ezvishandiso zvekugadzirisa uko nzvimbo dzemukati dzakachena zvakanyanya dzinofanirwa kucheneswa.
Kunze kweTubing: Zvimwe Zvakakosha paSisitimu Yese yeUHP
Kuti ive nechokwadi chekuti yakavimbika zvakakwana, sisitimu inofanirawo kusanganisira:
•
Kukwevera kweOrbital otomatiki zvizere- Inoitwa muISO Kirasi 5 (Kirasi 100) kana mumakamuri ekuchenesa ari nani, zvichibvisa kusiyana kwekunamira kwesimbi nemaoko uye njodzi dzekusvibiswa.
•
Zvishandiso zveSimbi Yese– Dzakadai semhando dzeVCR® kana W‑Seal, idzo dzinoshandisa magasket esimbi kuti dzisaburitse mvura zvachose.
•
Kuchenesa & Kurongedza Zvakasimba– Machubhu eEP anowanzo chenurwa nemvura yakachena, oomeswa, uye ocheneswa nenitrogen asati aiswa mumabhegi maviri mupakeji yemukamuri rakachena kuti arambe akachena kusvika aiswa.
EP tube haisi pombi chete—ndiyo nzira yekutanga yekudzivirira mukupa gasi re semiconductor. Pamusoro payo panyorova zvakanyanya, kuramba ngura kwakanyanya, uye kuchena kwezvinhu zvepamusoro zvinokanganisa zvakananga kugadzirwa kwewafer, kuvimbika kwemidziyo, uye purofiti yakanaka kwazvo. Munyika ine ma sub‑5nm nodes uye bhajeti remadhiragi akasimba, EP tube haisi yekusarudza—ndiyo yepakutanga.
