Photoresist yog tam sim no dav siv nyob rau hauv kev ua thiab zus tau tej cov graphic circuits nyob rau hauv lub optoelectronic ntaub ntawv kev lag luam. Tus nqi ntawm cov txheej txheem photolithography suav txog li 35% ntawm tag nrho cov txheej txheem tsim cov nti, thiab lub sijhawm siv nyiaj rau 40% txog 60% ntawm tag nrho cov txheej txheem nti. Nws yog cov txheej txheem tseem ceeb hauv kev tsim khoom semiconductor. Photoresist cov ntaub ntawv suav txog li 4% ntawm tag nrho cov nqi ntawm cov khoom siv chips thiab yog cov ntaub ntawv tseem ceeb rau semiconductor integrated circuit manufacturing.
Qhov kev loj hlob ntawm Tuam Tshoj lub photoresist kev lag luam yog siab dua li thoob ntiaj teb. Raws li cov ntaub ntawv los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Lag Luam Yav Tom Ntej, kuv lub teb chaws cov khoom siv hauv zos ntawm photoresist hauv 2019 yog kwv yees li 7 billion yuan, thiab qhov sib xyaw ua ke ntawm kev loj hlob txij li xyoo 2010 tau mus txog 11%, uas yog ntau dua li kev loj hlob thoob ntiaj teb. Txawm li cas los xij, cov khoom siv hauv zos tsuas yog kwv yees li 10% ntawm lub ntiaj teb sib koom, thiab kev hloov pauv hauv tsev tau ua tiav rau qhov qis kawg PCB photoresists. Tus kheej-sufficiency tus nqi ntawm photoresists nyob rau hauv lub LCD thiab semiconductor teb yog tsawg heev.
Photoresist yog cov duab hloov pauv nruab nrab uas siv qhov sib txawv solubility tom qab lub teeb pom kev los hloov lub npog ntsej muag rau hauv substrate. Nws yog tsim los ntawm photosensitive tus neeg sawv cev (photoinitiator), polymerizer (photosensitive resin), hnyav thiab additive.
Cov ntaub ntawv raw ntawm photoresist feem ntau yog cob, hnyav thiab lwm yam additives. Ntawm lawv, cov kuab tshuaj suav nrog qhov loj tshaj plaws, feem ntau ntau dua 80%. Txawm hais tias lwm cov additives suav nrog tsawg dua 5% ntawm cov huab hwm coj, lawv yog cov ntaub ntawv tseem ceeb uas txiav txim siab cov khoom tshwj xeeb ntawm photoresist, suav nrog photosensitizers, surfactants thiab lwm yam ntaub ntawv. Hauv cov txheej txheem photolithography, photoresist yog sib npaug ntawm cov substrates sib txawv xws li silicon wafers, iav thiab hlau. Tom qab kis tau, kev loj hlob thiab etching, tus qauv ntawm lub npog ntsej muag raug xa mus rau hauv zaj duab xis los tsim cov qauv geometric uas sib haum rau lub npog ntsej muag.
Photoresist tuaj yeem muab faib ua peb pawg raws li nws daim ntawv thov nram qab no: semiconductor photoresist, vaj huam sib luag photoresist thiab PCB photoresist.
Semiconductor photoresist
Tam sim no, KrF / ArF tseem yog cov khoom siv tseem ceeb. Nrog rau kev txhim kho ntawm kev sib xyaw ua ke, photolithography thev naus laus zis tau dhau los ntawm kev txhim kho los ntawm G-line (436nm) lithography, H-line (405nm) lithography, I-line (365nm) lithography, kom tob ultraviolet DUV lithography (KrF248nm thiab ArF193nm), 193nm immersion ntxiv rau ntau yam kev yees duab (32nm-7nm), thiab tom qab ntawd mus rau ultraviolet ultraviolet (EUV, <13.5nm) lithography, thiab txawm tias tsis yog-optical lithography (electron beam raug, ion beam raug), thiab ntau hom photoresists nrog sib xws wavelengths raws li photosensitive wavelengths kuj tau. siv.
Kev ua lag luam photoresist muaj cov qib siab ntawm kev lag luam concentration. Cov tuam txhab Japanese muaj qhov txiaj ntsig zoo hauv thaj chaw ntawm semiconductor photoresists. Lub ntsiab semiconductor photoresist manufacturers suav nrog Tokyo Ohka, JSR, Sumitomo Chemical, Shin-Etsu Chemical hauv Nyiv; Dongjin Semiconductor hauv Kaus Lim Qab Teb; thiab DowDuPont hauv Tebchaws Meskas, ntawm cov tuam txhab Japanese tuav txog 70% ntawm kev ua lag luam. Nyob rau hauv cov nqe lus ntawm cov khoom, Tokyo Ohka coj nyob rau hauv lub teb ntawm g-line / i-line thiab Krf photoresists, nrog kev ua lag luam shares ntawm 27.5% thiab 32.7% feem. JSR muaj kev lag luam siab tshaj plaws hauv kev lag luam ntawm Arf photoresist, ntawm 25.6%.
Raws li Fuji Economic kev kwv yees, lub ntiaj teb ArF thiab KrF kua nplaum tsim muaj peev xwm yuav tsum ncav cuag 1,870 thiab 3,650 tons hauv 2023, nrog rau kev lag luam loj ze li ntawm 4.9 billion thiab 2.8 billion yuan. Tag nrho cov nyiaj tau los ntawm Japanese photoresist thawj coj JSR thiab TOK, suav nrog photoresist, yog li 40%, ntawm cov nqi ntawm photoresist raw khoom suav txog li 90%.
Tuam Tshoj semiconductor photoresist manufacturers suav nrog Shanghai Xinyang, Nanjing Optoelectronics, Jingrui Co., Ltd., Beijing Kehua, thiab Hengkun Co., Ltd. Tam sim no, tsuas yog Beijing Kehua thiab Jingrui Co., Ltd. muaj peev xwm los tsim KrF photoresist loj , thiab Beijing Kehua cov khoom tau muab rau SMIC. Lub 19,000 tons / xyoo ArF (cov txheej txheem qhuav) photoresist project nyob rau hauv kev tsim kho nyob rau hauv Shanghai Xinyang xav kom ncav cuag tag nrho cov khoom nyob rau hauv 2022.
Vaj huam sib luag photoresist
Photoresist yog cov khoom tseem ceeb rau kev tsim vaj huam sib luag LCD. Raws li cov neeg siv sib txawv, nws tuaj yeem muab faib ua RGB kua nplaum, BM kua nplaum, OC kua nplaum, PS kua nplaum, TFT kua nplaum, thiab lwm yam.
Vaj huam sib luag photoresists feem ntau suav nrog plaub pawg: TFT thaiv photoresists, LCD / TP spacer photoresists, xim photoresists thiab dub photoresists. Ntawm lawv, TFT xov hlau photoresists yog siv rau ITO thaiv, thiab LCD / TP nag lossis daus photoresists yog siv los khaws cov thickness ntawm cov khoom siv lead ua kua ntawm ob lub iav substrates ntawm LCD tas li. Xim photoresists thiab dub photoresists tuaj yeem muab cov xim lim xim xim ua haujlwm.
Lub vaj huam sib luag photoresist kev lag luam yuav tsum muaj kev ruaj khov, thiab qhov kev thov rau xim photoresists yog thawj. Nws cia siab tias kev muag khoom thoob ntiaj teb yuav ncav cuag 22,900 tons thiab kev muag khoom yuav ncav cuag US $ 877 lab hauv 2022.
Kev muag khoom ntawm TFT vaj huam sib luag photoresists, LCD / TP spacer photoresists, thiab dub photoresists yuav tsum ncav cuag US $ 321 lab, US $ 251 lab, thiab US $ 199 lab nyob rau hauv 2022. Raws li Zhiyan Consulting qhov kwv yees, lub ntiaj teb no vaj huam sib luag photoresist kev lag luam loj yuav ncav cuag. RMB 16.7 billion hauv 2020, nrog kev loj hlob ntawm kwv yees li 4%. Raws li peb cov kev kwv yees, kev lag luam photoresist yuav ncav cuag RMB 20.3 billion los ntawm 2025. Ntawm lawv, nrog rau kev hloov ntawm LCD kev lag luam chaw, kev lag luam loj thiab localization tus nqi ntawm LCD photoresist nyob rau hauv kuv lub teb chaws yuav tsum maj mam nce.
PCB photoresist
PCB photoresist tuaj yeem muab faib ua UV curing number case thiab UV spray number case raws li txheej txheej txheej. Tam sim no, cov neeg muag khoom hauv PCB ink tau maj mam ua tiav kev hloov pauv hauv tsev, thiab cov tuam txhab xws li Rongda Photosensitive thiab Guangxin Materials tau paub txog cov thev naus laus zis tseem ceeb ntawm PCB number case.
Hauv tsev TFT photoresist thiab semiconductor photoresist tseem nyob rau theem pib tshawb nrhiav. Jingrui Co., Ltd., Yak Technology, Yongtai Technology, Rongda Photosensitive, Xinyihua, Tuam Tshoj Electronics Zaj sawv, thiab Feikai cov ntaub ntawv txhua tus muaj layouts nyob rau hauv lub tshav pob ntawm TFT photoresist. Ntawm lawv, Feikai Cov Khoom Siv thiab Beixu Electronics tau npaj muaj peev xwm tsim tau txog li 5,000 tons / xyoo. Yak Technology tau nkag mus rau hauv kev lag luam no los ntawm kev tau txais cov xim photoresist faib ntawm LG Chem, thiab muaj qhov zoo ntawm cov channel thiab thev naus laus zis.
Rau kev lag luam uas muaj kev cuam tshuam tsis zoo xws li photoresist, kev ua tiav ntawm cov txheej txheem yog lub hauv paus, thiab qhov thib ob, kev txhim kho txuas ntxiv ntawm cov txheej txheem yuav tsum tau ua kom tau raws li cov kev xav tau ntawm kev loj hlob sai ntawm kev lag luam semiconductor.
Zoo siab txais tos rau peb lub vev xaib kom paub cov khoom lag luam thiab kev sib tham.
