Photoresist o loʻo faʻaaogaina i le taimi nei i le gaosiga ma le gaosiga o faʻataʻitaʻiga faʻataʻitaʻi lelei i totonu o faʻamatalaga faʻamatalaga optoelectronic. O le tau o le photolithography e tusa ma le 35% o le faagasologa atoa o le gaosiga o chip, ma o le taimi e faʻaaogaina ai le 40% i le 60% o le faagasologa atoa o chip. O le fa'agasologa autu i le gaosiga o semiconductor. E tusa ma le 4% o le aofaʻi o tau o mea gaosi mea e gaosia ai ata ma o mea autu ia mo le gaosiga o le semiconductor integrated circuit manufacturing.
Ole fua ole tuputupu aʻe ole maketi photoresist a Saina e maualuga atu nai lo tulaga faʻavaomalo. E tusa ai ma faʻamatalaga mai le Prospective Industry Research Institute, o loʻu atunuʻu i le lotoifale o le photoresist i le 2019 e tusa ma le 7 piliona yuan, ma o le aofaʻi o le tuputupu aʻe talu mai le 2010 ua oʻo i le 11%, lea e sili atu le maualuga nai lo le faʻatupulaia o le lalolagi. Ae ui i lea, o le sapalai i le lotoifale e na o le tusa ma le 10% o le vaega o le lalolagi, ma o le suiga i totonu o le atunuu ua ausia aemaise lava mo PCB photoresists maualalo. O le fua faatatau o le ola tutoatasi o photoresists i le LCD ma semiconductor fanua e matua maualalo lava.
O le Photoresist ose fa'asolo fa'akalafi e fa'aogaina ai le solubility eseese pe a mae'a le fa'amama malamalama e fa'afeiloa'i ai le mamanu matapulepule i le mea'ai. E masani ona aofia ai le photosensitive sui (photoinitiator), polymerizer (photosensitive resin), solvent ma faʻaopoopoga.
O mea mata o photoresist e tele lava resin, solvent ma isi additives. Faatasi ai ma i latou, o le solvent tala mo le tele o vaega, e masani lava e sili atu i le 80%. E ui lava o isi mea faʻaopoopo e faʻatatau i lalo ifo o le 5% o le tele, o mea autu ia e fuafua ai uiga faʻapitoa o photoresist, e aofia ai photosensitizers, surfactants ma isi mea. I le faagasologa o le photolithography, o le photoresist o loʻo faʻapipiʻi tutusa i luga o mea eseese e pei o le silicon wafers, tioata ma uʻamea. A maeʻa ona faʻaalia, atinaʻe ma faʻapipiʻi, o le mamanu i luga o le mask e faʻafeiloaʻi i le ata e fai ai se mamanu geometric e fetaui lelei ma le mask.
Photoresist e mafai ona vaevaeina i ni vaega se tolu e tusa ai ma ona fanua talosaga lalo: semiconductor photoresist, panel photoresist ma PCB photoresist.
