Photoresist parizvino inoshandiswa zvakanyanya mukugadzirisa nekugadzira yakanaka graphic maseketi muindasitiri yeruzivo yeoptoelectronic. Mutengo weiyo photolithography process inosvika 35% yeiyo yese chip kugadzira process, uye nguva yekushandisa inotora 40% kusvika 60% yeiyo chip process yese. Ndiyo musimboti muitiro mukugadzira semiconductor. Photoresist zvinhu zvinoverengera inosvika 4% yemutengo wakakwana wekugadzira chip zvinhu uye ndizvo zvepakati zvekugadzira semiconductor yakabatanidzwa yedunhu kugadzira.
Mwero wekukura kwemusika weChina photoresist wakakwira kupfuura mwero wepasirese. Zvinoenderana nedata kubva kuProspective Indasitiri Research Institute, nyika yangu yemuno yephotoresist muna 2019 yaive mabhiriyoni manomwe eyuan, uye huwandu hwekukura kubva 2010 hwasvika 11%, iyo yakakwira zvakanyanya kupfuura mwero wekukura kwepasirese. Nekudaro, iyo yekugovera yemuno inongoverengera chete gumi muzana yemugove wepasirese, uye kutsiva kwepamba kwave kuwanikwa kunyanya kune yakaderera-yekupedzisira PCB photoresists. Iyo yekuzvimiririra mwero yephotoresists muLCD uye semiconductor minda yakaderera zvakanyanya.
Photoresist idhizaini yekufambisa svikiro inoshandisa kunyungudika kwakasiyana mushure mekuita kwechiedza kuendesa iyo mask pateni kune substrate. Iyo inonyanya kuumbwa nephotosensitive agent (photoinitiator), polymerizer (photosensitive resin), solvent uye additive.
Izvo zvigadzirwa zve photoresist zvakanyanya resin, solvent uye zvimwe zvinowedzera. Pakati pavo, solvent accounts yechikamu chikuru, kazhinji chinodarika 80%. Kunyangwe zvimwe zvinowedzerwa zvichiverengera isingasviki 5% yehuremu, iwo akakosha emidziyo inotaridza yakasarudzika zvimiro zvephotoresist, zvinosanganisira photosensitizers, surfactants uye zvimwe zvinhu. Muchiitiko chephotolithography, photoresist yakavharwa zvakaenzana pamasubstrates akasiyana sesilicon wafers, girazi nesimbi. Mushure mekuratidzwa, kusimudzira uye etching, iyo pateni pane mask inotamirwa kune iyo firimu kuti iite geometric pateni inoenderana zvachose nemasikisi.
Photoresist inogona kupatsanurwa muzvikamu zvitatu zvinoenderana neayo ezasi application minda: semiconductor photoresist, panel photoresist uye PCB photoresist.
Semiconductor photoresist
Parizvino, KrF/ArF ichiri iyo huru yekugadzirisa zvinhu. Nekuvandudzwa kwemasekete akabatanidzwa, tekinoroji yefotolithography yakapfuura nekuvandudzwa kubva kuG-line (436nm) lithography, H-line (405nm) lithography, I-line (365nm) lithography, kusvika pakadzika ultraviolet DUV lithography (KrF248nm uye ArF193nm), 193nm kunyudzwa pamwe neakawanda ekufungidzira tekinoroji (32nm-7nm), uyezve kunyanyisa. ultraviolet (EUV, <13.5nm) lithography, uye kunyange isiri-optical lithography (electron beam exposure, ion beam exposure), uye marudzi akasiyana-siyana emaphotoresist ane wavelengths anoenderana sezvo photosensitive wavelengths akaiswawo.
Musika wephotoresist une dhigirii repamusoro rekutariswa kwemaindasitiri. Makambani eJapan ane mukana wakakwana mumunda we semiconductor photoresists. Iwo makuru semiconductor photoresist vagadziri vanosanganisira Tokyo Ohka, JSR, Sumitomo Chemical, Shin-Etsu Chemical muJapan; Dongjin Semiconductor muSouth Korea; uye DowDuPont muUnited States, pakati pemakambani eJapan anotora 70% yemugove wemusika. Panyaya yezvigadzirwa, Tokyo Ohka inotungamira muminda yeg-line/i-line uye Krf photoresists, ine migove yemusika ye27.5% uye 32.7% zvichiteerana. JSR ine chikamu chepamusoro chemusika mumunda weArf photoresist, pa25.6%.
Zvinoenderana nefungidziro yeFuji Economic, iyo yepasi rose yeArF neKrF glue yekugadzira inotarisirwa kusvika 1,870 uye 3,650 matani muna 2023, nehukuru hwemusika hunosvika mabhiriyoni 4.9 uye 2.8 bhiriyoni yuan. Iyo gross profit margin yevatungamiri veJapan photoresist JSR neTOK, kusanganisira photoresist, ingangoita 40%, iyo mutengo we photoresist mbishi zvinhu unosvika makumi mapfumbamwe%.
Vagadziri vepamusha semiconductor photoresist vagadziri vanosanganisira Shanghai Xinyang, Nanjing Optoelectronics, Jingrui Co., Ltd., Beijing Kehua, uye Hengkun Co., Ltd. Parizvino, Beijing Kehua neJingrui Co., Ltd chete ndivo vanokwanisa kugadzira KrF photoresist. , uye zvigadzirwa zveBeijing Kehua zvakapihwa kuSMIC. Iyo 19,000 matani / gore ArF (yakaoma process) photoresist chirongwa chiri kuvakwa muShanghai Xinyang inotarisirwa kusvika kuzara kugadzirwa muna 2022.
Panel photoresist
Photoresist chinhu chakakosha cheLCD pani kugadzira. Zvinoenderana nevashandisi vakasiyana, inogona kukamurwa kuita RGB glue, BM glue, OC glue, PS glue, TFT glue, nezvimwe.
Panel photoresists inonyanya kusanganisira zvikamu zvina: TFT wiring photoresists, LCD/TP spacer photoresists, color photoresists uye vatema photoresists. Pakati pazvo, TFT wiring photoresists inoshandiswa kune ITO wiring, uye LCD/TP precipitation photoresists inoshandiswa kuchengetedza ukobvu hwemvura yekristaro zvinhu pakati pemagirazi maviri substrates eLCD nguva dzose. Color photoresists uye vatema photoresists vanogona kupa mavara mafirita emavara ekupa mabasa.
Iyo mapaneru photoresist musika inoda kugadzikana, uye kudiwa kwemavara photoresists kuri kutungamira. Zvinotarisirwa kuti kutengesa kwepasirese kuchasvika 22,900 matani uye kutengesa kuchasvika US $ 877 miriyoni muna 2022.
Kutengeswa kweTFT panel photoresists, LCD/TP spacer photoresists, uye vatema photoresist vanotarisirwa kusvika US$321 miriyoni, US$251 miriyoni, uye US$199 miriyoni zvakateerana muna 2022. Maererano nefungidziro yeZhiyan Consulting, musika wepasi rose wepasi rose wephotoresist uchasvika. RMB 16.7 bhiriyoni muna 2020, nehuwandu hwekukura hunosvika 4%. Maererano nekufungidzira kwedu, misika ye photoresist ichasvika RMB 20.3 bhiriyoni ne 2025. Pakati pavo, nekuendeswa kweLCD industry centre, ukuru hwemusika uye chiyero chenzvimbo yeLCD photoresist munyika yangu zvinotarisirwa kuwedzera zvishoma nezvishoma.
PCB photoresist
PCB photoresist inogona kupatsanurwa kuita UV kurapa inki uye UV pfapfaidzo ingi zvinoenderana nekututira nzira. Parizvino, vatengesi veingi vePCB vepamba vakawana zvishoma nezvishoma kutsiva mudzimba, uye makambani akadai seRongda Photosensitive neGuangxin Materials akaziva tekinoroji yakakosha yePCB inki.
Domestic TFT photoresist uye semiconductor photoresist vachiri muchikamu chekutanga chekuongorora. Jingrui Co., Ltd., Yak Technology, Yongtai Technology, Rongda Photosensitive, Xinyihua, China Electronics Rainbow, uye Feikai Materials ese ane marongero mumunda weTFT photoresist. Pakati pavo, Feikai Materials uye Beixu Electronics vakaronga kugadzirwa kweanosvika zviuru zvishanu zvematani / gore. Yak Technology yakapinda mumusika uyu nekuwana iyo color photoresist division ye LG Chem, uye ine zvakanakira mumachaneli uye tekinoroji.
Kune maindasitiri ane zvakanyanyisa zvipingamupinyi zvehunyanzvi senge photoresist, kuwana mabhindauko padanho rehunyanzvi ndiyo hwaro, uye chechipiri, kuenderera mberi kwekuvandudza kwemaitiro kunodiwa kusangana nezvinodiwa zvekukurumidza kusimudzira kweindasitiri yesemiconductor.
Kugamuchirwa kune webhusaiti yedu yeruzivo rwechigadzirwa uye kubvunzana.
