Ifotoresist okwangoku isetyenziswa ngokubanzi ekusetyenzweni nasekuveliseni iisekethe zemizobo entle kwishishini lolwazi lwe-optoelectronic. Iindleko zenkqubo ye-photolithography i-akhawunti malunga ne-35% yenkqubo yonke yokuvelisa i-chip, kwaye ixesha lokusetyenziswa libalelwa kwi-40% ukuya kwi-60% yenkqubo yonke ye-chip. Yinkqubo engundoqo kwimveliso ye-semiconductor. I-Photoresist imathiriyeli ithatha malunga ne-4% yexabiso lilonke lemathiriyeli yokwenziwa kwetshiphu kwaye zizinto eziphambili zokwenziwa kwesekethe edibeneyo ye-semiconductor.
Izinga lokukhula kwemarike ye-photoresist yaseChina iphezulu kunenqanaba lehlabathi. Ngokwedatha evela kwiZiko loPhando loShishino olulindelekileyo, unikezelo lwelizwe lam lwe-photoresist ngo-2019 lwalumalunga neebhiliyoni ezisi-7 zeeyuan, kwaye izinga lokukhula elihlanganisiweyo ukusukela ngo-2010 lifikelele kwi-11%, eliphezulu kakhulu kunezinga lokukhula kwehlabathi. Nangona kunjalo, unikezelo lwasekhaya lubalelwa kuphela malunga ne-10% yesabelo sehlabathi, kwaye ukutshintshwa kwasekhaya kuye kwaphunyezwa ikakhulu kwi-photoresists ye-PCB ephantsi. Izinga lokuzanelisa kwe-photoresists kwi-LCD kunye nemimandla ye-semiconductor iphantsi kakhulu.
Ifotoresist sisixhobo sokudlulisa umzobo esisebenzisa ukunyibilika okwahlukileyo emva kokusabela kokukhanya ukuhambisa ipateni yemaski kwi-substrate. Ubukhulu becala yenziwe nge-agent ye-photosensitive (photoinitiator), i-polymerizer (i-photosensitive resin), i-solvent kunye ne-additive.
Izinto eziluhlaza ze-photoresist ziyi-resin, i-solvent kunye nezinye izongezo. Phakathi kwazo, i-solvent akhawunti yeyona nxalenye inkulu, ngokubanzi ngaphezu kwe-80%. Nangona ezinye izongezo zibalelwa ngaphantsi kwe-5% yobunzima, zizinto eziphambili ezibonisa iimpawu ezizodwa ze-photoresist, kubandakanywa i-photosensitizers, i-surfactants kunye nezinye izinto. Kwinkqubo ye-photolithography, i-photoresist ifakwe ngokulinganayo kwii-substrates ezahlukeneyo ezifana ne-silicon wafers, iglasi kunye nentsimbi. Emva kokuvezwa, uphuhliso kunye nokudibanisa, iphethini kwimaski idluliselwa kwifilimu ukwenza ipateni yejometri ehambelana ngokupheleleyo nemaski.
I-Photoresist inokwahlulwa ibe ngamacandelo amathathu ngokwemimandla yesicelo esezantsi: i-semiconductor photoresist, i-photoresist yephaneli kunye ne-PCB photoresist.
Semiconductor photoresist
Okwangoku, i-KrF/ArF iseyeyona nto iphambili yokusetyenzwa. Ngophuhliso lweesekethe ezidibeneyo, iteknoloji ye-photolithography iye yahamba ngophuhliso oluvela kwi-G-line (436nm) lithography, i-H-line (405nm) lithography, i-I-line (365nm) lithography, ukuya kwi-ultraviolet DUV lithography enzulu (KrF248nm kunye ne-ArF193nm), Ukuntywiliselwa kwe-193nm kunye netekhnoloji yokucinga ezininzi (32nm-7nm), kwaye emva koko igqithise I-ultraviolet (EUV, <13.5nm) i-lithography, kunye ne-non-optical lithography (i-electron beam exposure, i-ion beam exposure), kunye neentlobo ezahlukeneyo ze-photoresists ezinamaza ahambelanayo njengamaza e-photosensitive nazo zisetyenzisiwe.
Imakethi ye-photoresist inenqanaba eliphezulu lokugxila kwishishini. Iinkampani zaseJapan zinenzuzo ngokupheleleyo kwicandelo le-semiconductor photoresists. Abavelisi abaphambili be-semiconductor photoresist baquka iTokyo Ohka, JSR, iSumitomo Chemical, iShin-Etsu Chemical eJapan; I-Dongjin Semiconductor eMzantsi Korea; kunye neDowDuPont eMelika, phakathi kwazo iinkampani zaseJapan zithatha malunga ne-70% yesabelo semarike. Ngokumalunga neemveliso, i-Tokyo Ohka ikhokela kwiinkalo ze-g-line / i-line kunye ne-Krf photoresists, kunye nezabelo zemarike ze-27.5% kunye ne-32.7% ngokulandelanayo. I-JSR inesona sabelo siphezulu semarike kummandla we-Arf photoresist, kwi-25.6%.
Ngokwengqikelelo yeFuji Economic, umthamo weglu yehlabathi jikelele weArF kunye neKrF kulindeleke ukuba ufikelele kwi-1,870 kunye ne-3,650 yeetoni ngo-2023, kunye nobukhulu bemarike obuphantse buzibhiliyoni ezi-4.9 kunye ne-2.8 yeebhiliyoni zeeyuan. Umda wengeniso yengeniso yeenkokeli zaseJapan ze-photoresist JSR kunye ne-TOK, kubandakanywa ne-photoresist, malunga ne-40%, apho iindleko ze-photoresist izinto eziluhlaza zenza malunga ne-90%.
Abavelisi be-semiconductor photoresist basekhaya baquka iShanghai Xinyang, iNanjing Optoelectronics, iJingrui Co., Ltd., iBeijing Kehua, kunye neHengkun Co., Ltd. Okwangoku, yiBeijing Kehua kunye neJingrui Co., Ltd. kuphela ezikwaziyo ukuvelisa ngobuninzi i-KrF photoresist. , kunye neemveliso zeBeijing Kehua zinikezelwe kwi-SMIC. I-19,000 yeetoni / ngonyaka i-ArF (inkqubo eyomileyo) iprojekthi ye-photoresist esakhiwa e-Shanghai Xinyang kulindeleke ukuba ifikelele kwimveliso epheleleyo ngo-2022.
Iphaneli yefotoresist
Ifotoresist sisixhobo esiphambili sokwenza ipaneli yeLCD. Ngokwabasebenzisi abahlukeneyo, inokwahlulwa ibe yiglue ye-RGB, iglue ye-BM, iglue ye-OC, iglu ye-PS, iglu ye-TFT, njl.
I-Panel photoresists ikakhulu ibandakanya iindidi ezine: i-TFT yocingo yokufota, i-LCD/TP spacer photoresists, i-photoresists yemibala kunye ne-photoresists emnyama. Phakathi kwazo, ii-TFT wiring photoresists zisetyenziselwa i-ITO wiring, kunye ne-LCD/TP precipitation photoresists zisetyenziselwa ukugcina ubukhulu bezinto zekristale yolwelo phakathi kwee-substrates ezimbini zeglasi ye-LCD engaguqukiyo. Iifotoresist zemibala kunye neefotoresist ezimnyama zinokunika izihluzi zemibala imisebenzi yokubonisa umbala.
Imarike ye-photoresist yephaneli kufuneka izinzile, kwaye imfuno ye-photoresists yombala ikhokela. Kulindeleke ukuba intengiso yehlabathi ifikelele kwiitoni ezingama-22,900 kwaye intengiso iya kufikelela kwi-US $877 yezigidi ngo-2022.
Ukuthengiswa kwee-photoresists zephaneli ye-TFT, i-LCD/TP spacer photoresists, kunye ne-photoresist emnyama kulindeleke ukuba ifikelele kwi-US $ 321 yezigidi, i-US $ 251 yezigidi, kunye ne-US $ 199 yezigidi ngokulandelelanayo ngo-2022. Ngokoqikelelo lwe-Zhiyan Consulting, i-panel ye-global photoresist ubukhulu buya kufikelela. I-RMB 16.7 yeebhiliyoni ngo-2020, ngesantya sokukhula malunga ne-4%. Ngokoqikelelo lwethu, imarike photoresist iya kufikelela RMB 20.3 billion ngo 2025. Phakathi kwabo, kunye nokudluliselwa LCD iziko ishishini, ubungakanani imarike kunye nezinga lendawo ye-LCD photoresist kwilizwe lam kulindeleke ukuba kancane kancane ukwanda.
PCB photoresist
I-PCB photoresist inokohlulwa ibe yi-inki yokunyanga ye-UV kunye ne-inki yokutshiza ye-UV ngokwendlela yokwaleka. Okwangoku, ababoneleli be-inki be-PCB basekhaya baye bazuza ngokuthe ngcembe endaweni yasekhaya, kwaye iinkampani ezifana ne-Rongda Photosensitive kunye ne-Guangxin Materials ziye zakwazi ubugcisa obuphambili be-inki ye-PCB.
I-photoresist ye-TFT yasekhaya kunye ne-semiconductor photoresist isekwinqanaba lokuqala lokuhlola. Jingrui Co., Ltd., Yak Technology, Yongtai Technology, Rongda Photosensitive, Xinyihua, China Electronics Rainbow, kunye neFeikai Materials zonke zinezakhiwo kwintsimi ye-TFT photoresist. Phakathi kwazo, i-Feikai Materials kunye ne-Beixu Electronics zicwangcise umthamo wokuvelisa ukuya kuthi ga kwi-5,000 yeetoni / ngonyaka. I-Yak Technology ingene kule marike ngokufumana icandelo le-photoresist yombala we-LG Chem, kwaye ineenzuzo kwiitshaneli kunye nobuchwepheshe.
Kumashishini anemiqobo ephezulu kakhulu yobugcisa efana ne-photoresist, ukufezekisa ukuphumelela kwinqanaba lobugcisa kusisiseko, kwaye okwesibini, ukuphuculwa okuqhubekayo kweenkqubo kuyafuneka ukuhlangabezana neemfuno zophuhliso olukhawulezayo lweshishini le-semiconductor.
