Kuki sisitemu zo gutanga gaze za UHP ari ingenzi cyane?
Mu nganda zikora ibikoresho bya semiconductor—nk'uburyo bwo gushushanya, CVD, gushyiramo ion, na lithography—imyuka igomba kuba ifite ubuziranenge buhanitse cyane, akenshi 99.9999% (6N) cyangwa 99.99999% (7N). Ndetse n'ibintu bihumanya biri ku rwego rwa ppb (ibice kuri miliyari) cyangwa ppt (ibice kuri tiriyari)—nk'ubushuhe cyangwa ogisijeni—bishobora gutera inenge zikomeye nko kugabanya gate oxide, ububobere bw'icyuma, cyangwa imiyoboro migufi ku byuma bya wafer, bishobora gusibanganya ahantu hose.
Intego ya sisitemu yo gutanga imyuka ya UHP rero ni ugutwara imyuka iva ku isoko ijya mu gikoresho cyo kuyitunganya nta kwangirika mu buryo buboneye, hirindwa kwandura no gusohoka ahantu hose.
Kuki EP Tubing iba inkingi y'umugongo wa UHP Systems?
Umuyoboro wa EP (Electropolished) ukorwa mu cyuma kitagira umugese gikoreshwa mu gusiga irangi ry’amashanyarazi, bigatanga ubuso bw’imbere bumeze nk’indorerwamo. Ibi bituma uba "umutsi" w’ingenzi mu gukwirakwiza gaze ya UHP.
Isuku y'ikirenga - Kwirinda aho umuntu aturuka
Gutunganya EP bigabanya ubukana bw'imbere mu buso (Ra) kugeza kuri 0.13 µm – 0.25 µm cyangwa munsi yayo. Ubu buryo bworoshye cyane bukuraho imyenge mito cyane n'ahantu ho gukurura, bigatuma nta mwanya w'uduce duto, iyoni z'ibyuma, cyangwa ubushuhe byo gufatana.
Ubudahangarwa bw'Ingeso - Kubungabunga Isuku
Intambwe yo gutunganya amashanyarazi ikuraho imyanda yo hejuru kandi igakora urwego rudafite chrome oxide nyinshi, ikongera cyane ubudahangarwa ku myuka yangiza nka Cl₂, CF₄, na HCl. Ibi birinda ingese ku nkuta z'imiyoboro ishobora gutera uduce duto cyangwa kwanduza imyuka.
Kongera ubushobozi bwo gukoresha amazi neza no kuyasukura vuba
Urukuta rw'imbere rworoshye rugabanya ubushobozi bwo kudakora neza kw'amazi kandi rwihutisha gusukura no gusimbuza gazi. Mu bikorwa bisaba guhinduranya gazi vuba, ibi bigabanya igihe cyo gukora kandi byongera umusaruro mwiza.
Ibikoresho by'Icyubahiro - Igipimo cya "Ikamba"
Imiyoboro ya EP y’ubuziranenge ikorwa mu cyuma cya VIM-VAR cya 316L (Vacuum Induction Melting + Vacuum Arc Remelting). Ubu buryo bwo gushonga kabiri butuma icyuma cy’ibanze gisukura cyane, ari na cyo kintu cy’ingenzi kugira ngo EP igere ku musaruro mwiza.
Ingero z'Ishyirwa mu Bikorwa ry'Ingenzi
•
Inzira z'ingenzi– Gutanga imyuka ikora neza cyane kugira ngo ikoreshwe mu gushushanya, CVD, ishyirwamo iyoni, na lithography.
•
Imyuka yihariye– Gufata neza imyuka ishobora gushya, uburozi, cyangwa yangiza nka SiH₄, PH₃, Cl₂, na BCl₃. Ku myuka iteje akaga cyane, imiyoboro ya EP ikoreshwa inshuro ebyiri ikunze gukoreshwa (umuyoboro w'imbere wa gaze, umuyoboro w'inyuma wavanwamo cyangwa ugasukurwa na azote kugira ngo ugenzure amazi asohoka).
•
Ibikoresho by'ingenzi– Ikoreshwa mu bikoresho byo gukwirakwiza gazi (VMBs), mu makabati ya gazi, no mu bikoresho byo gutunganya aho ubuso bw'imbere busukuye cyane ari ngombwa.
Uretse Tubing: Ibindi by'ingenzi kugira ngo sisitemu yuzuye ya UHP ikoreshwe
Kugira ngo habeho ubuziranenge busesuye, sisitemu igomba kandi kuba irimo:
•
Gusudira mu buryo bwikora ku buryo bwikora– Bikorerwa mu cyumba cy’isuku cya ISO 5 (Icyiciro cya 100) cyangwa mu byumba byiza kurushaho, bikuraho ihindagurika ry’ubusugudi n’ibyago byo kwandura.
•
Ibikoresho byo gupfuka isura by'icyuma cyose– Nk’ubwoko bwa VCR® cyangwa W, bushingiye ku byuma bitagira amashanyarazi kugira ngo bitavamo amazi.
•
Isuku n'ibipfunyika mu buryo bwimbitse– Imiyoboro ya EP isanzwe isukurwa n'amazi meza cyane, ikamishwa, hanyuma igasukurwa na azote mbere yo gushyirwa mu mapaki abiri mu cyumba gisukuye kugira ngo igumane ubuziranenge bwayo “nk’uko yoherejwe” kugeza igihe ishyiriwe.
Imiyoboro ya EP si umuyoboro gusa—ni wo murongo wa mbere w’uburinzi mu gutanga gaze ya semiconductor. Ubuso bwayo bworoshye cyane, kurwanya ingese cyane, hamwe n’ubuziranenge bw’ibikoresho bigira ingaruka ku musaruro wa wafer, kwizera ibikoresho, ndetse n’inyungu rusange. Mu isi y’uduce duto twa 5nm n’ingengo y’imari igenda irushaho kuba nto, imiyoboro ya EP si amahitamo—ni ishingiro.
