Photoresist ke mokhoa oa ho fetisa litšoantšo o sebelisang ho qhibiliha ho fapaneng ka mor'a karabelo e bobebe ho fetisetsa mohlala oa mask ho substrate. Haholo-holo e entsoe ka li-photosensitive agent (photoinitiator), polymerizer (photosensitive resin), solvent le addititive.
Lisebelisoa tse tala tsa photoresist ke haholo-holo resin, solvent le li-additives tse ling. Har'a tsona, li-solvents li nka karolo e kholo ka ho fetisisa, hangata e fetang 80%. Le hoja li-additives tse ling li nka karolo e ka tlaase ho 5% ea boima, ke lisebelisoa tsa bohlokoa tse khethollang thepa e ikhethang ea photoresist, ho akarelletsa le photosensitizers, surfactants le lisebelisoa tse ling. Ts'ebetsong ea photolithography, photoresist e koahetsoe ka ho lekana holim'a likaroloana tse fapaneng tse kang li-wafers tsa silicon, khalase le tšepe. Ka mor'a ho pepeseha, nts'etsopele le etching, mohlala oa mask o fetisetsoa filiming ho etsa mokhoa oa geometri o lumellanang ka ho feletseng le mask.
Photoresist e ka aroloa ka mekhahlelo e meraro ho latela likarolo tsa eona tse tlase tsa kopo: semiconductor photoresist, phanele photoresist le PCB photoresist.
Semiconductor photoresist
Hajoale, KrF/ArF e ntse e le sesebelisoa sa mantlha sa ho sebetsa. Ka nts'etsopele ea lipotoloho tse kopantsoeng, theknoloji ea photolithography e fetile tsoelo-pele ho tloha G-line (436nm) lithography, H-line (405nm) lithography, I-line (365nm) lithography, ho ea botebong ba ultraviolet DUV lithography (KrF248nm le ArF193nm), Ho qoelisoa ka 193nm hammoho le theknoloji ea litšoantšo tse ngata (32nm-7nm), ebe ho feteletsa ultraviolet (EUV, <13.5nm) lithography, esita le non-optical lithography (electron beam exposure, ion beam exposure), le mefuta e fapaneng ea li-photoresist tse nang le wavelengths tse tsamaellanang joalo ka ha li-photosensitive wavelengths le tsona li sebelisitsoe.
Mmaraka oa photoresist o na le boemo bo phahameng ba khatello ea maikutlo indastering. Likhamphani tsa Majapane li na le monyetla o felletseng lefapheng la li-photoresists tsa semiconductor. Baetsi ba ka sehloohong ba semiconductor photoresist ba kenyelletsa Tokyo Ohka, JSR, Sumitomo Chemical, Shin-Etsu Chemical ea Japane; Semiconductor ea Dongjin Korea Boroa; le DowDuPont United States, eo har'a eona lik'hamphani tsa Majapane li nkang karolo ea 70% ea 'maraka. Mabapi le lihlahisoa, Tokyo Ohka e etella pele mafapheng a g-line/i-line le Krf photoresists, ka likarolo tsa mmaraka tsa 27.5% le 32.7% ka ho latellana. JSR e na le karolo e phahameng ka ho fetisisa ea mmaraka tšimong ea Arf photoresist, ho 25.6%.
Ho latela ponelopele ea Fuji Economic, matla a lefats'e a tlhahiso ea glue ea ArF le KrF e lebelletsoe ho fihla ho lithane tse 1,870 le 3,650 ka 2023, ka boholo ba mmaraka bo ka bang limilione tse likete tse 4.9 le li-yuan tse limilione tse likete tse 2.8. Phaello e kholo ea baeta-pele ba lifoto tsa Majapane JSR le TOK, ho kenyelletsa le photoresist, ke hoo e ka bang 40%, eo litšenyehelo tsa thepa e tala ea photoresist li etsang hoo e ka bang 90%.
Baetsi ba li-photoresist tsa lapeng ba kenyelletsa Shanghai Xinyang, Nanjing Optoelectronics, Jingrui Co., Ltd., Beijing Kehua, le Hengkun Co., Ltd. Hajoale, ke Beijing Kehua le Jingrui Co., Ltd. feela ba nang le bokhoni ba ho hlahisa ka bongata setsebi sa lifoto tsa KrF. , 'me lihlahisoa tsa Beijing Kehua li fanoe ho SMIC. Morero oa 19,000 tons/year ArF (dry process) photoresist projeke e ntseng e hahuoa Shanghai Xinyang e lebelletsoe ho fihlela tlhahiso e felletseng ka 2022.
Panel photoresist
Photoresist ke sesebelisoa sa bohlokoa bakeng sa tlhahiso ea liphanele tsa LCD. Ho latela basebelisi ba fapaneng, e ka aroloa ka sekhomaretsi sa RGB, BM glue, OC glue, PS glue, TFT glue, jj.
Li-panel photoresists haholo-holo li kenyelletsa mekhahlelo e mene: TFT wiring photoresists, LCD/TP spacer photoresists, color photoresists le black photoresists. Har'a tsona, li-photoresists tsa lithapo tsa TFT li sebelisetsoa wiring ea ITO, 'me li-photoresists tsa LCD/TP li sebelisoa ho boloka botenya ba thepa ea kristale ea mokelikeli pakeng tsa likarolo tse peli tsa khalase tsa LCD kamehla. Li-photoresist tsa mebala le li-photoresists tse ntšo li ka fana ka li-filters tsa mebala mesebetsi ea ho fana ka mebala.
Mmaraka oa phanele oa photoresist o hloka ho tsitsa, mme tlhokahalo ea li-photoresists tsa mebala e etella pele. Ho lebelletsoe hore thekiso ea lefats'e e tla fihla ho lithane tse 22,900 mme thekiso e tla fihla ho $ 877 milione ka 2022.
Lithekiso tsa li-photoresists tsa TFT panel, li-photoresists tsa LCD/TP spacer, le li-photoresist tse ntšo li lebelletsoe ho fihla ho US $321 milione, US $251 milione, le US $199 milione ka ho latellana ka 2022. Ho ea ka likhakanyo tsa Zhiyan Consulting, boholo ba 'maraka oa lefatše lohle oa photoresist bo tla fihla. RMB 16.7 bilione ka 2020, ka sekhahla sa kholo e ka bang 4%. Ho ea ka likhakanyo tsa rona, 'maraka oa photoresist o tla fihla ho RMB 20,3 limilione tse likete ka 2025. Har'a bona, ka ho fetisoa ha setsi sa indasteri ea LCD, boholo ba maraka le sekhahla sa sebaka sa LCD photoresist naheng ea heso se lebelletsoe ho eketseha butle-butle.
PCB photoresist
PCB photoresist e ka aroloa ka enke e phekolang ea UV le enke ea spray ea UV ho latela mokhoa oa ho roala. Hajoale, barekisi ba enke ba lapeng ba PCB ba fihletse phetoho ea lapeng butle-butle, 'me lik'hamphani tse kang Rongda Photosensitive le Guangxin Materials li tseba mekhoa ea bohlokoa ea theknoloji ea PCB.
TFT photoresist ea malapeng le semiconductor photoresist ba ntse ba le mothating oa pele oa ho hlahloba. Jingrui Co., Ltd., Yak Technology, Yongtai Technology, Rongda Photosensitive, Xinyihua, China Electronics Rainbow, le Feikai Materials kaofela li na le meralo lebaleng la TFT photoresist. Har'a bona, Feikai Materials le Beixu Electronics li rerile bokhoni ba tlhahiso ea ho fihla ho lithane tse 5,000 / selemo. Yak Technology e kene 'marakeng ona ka ho fumana karolo ea LG Chem ea color photoresist,' me e na le melemo ho liteishene le theknoloji.
