Chidule cha Photoresist
Photoresist, yomwe imadziwikanso kuti photoresist, imatanthauza chinthu chopyapyala chomwe kusungunuka kwake kumasintha chikakumana ndi kuwala kwa UV, ma elekitironi, ma ion beams, ma X-rays, kapena ma radiation ena.
Imapangidwa ndi utomoni, choyambitsa kuwala, chosungunulira kuwala, monomer, ndi zina zowonjezera (onani Gome 1). Utomoni ndi choyambitsa kuwala ndi zinthu zofunika kwambiri zomwe zimakhudza magwiridwe antchito a kuwala. Umagwiritsidwa ntchito ngati chophimba choletsa dzimbiri panthawi ya njira yowunikira kuwala.
Pokonza malo a semiconductor, kugwiritsa ntchito photoresist yoyenera kungapangitse chithunzi chomwe mukufuna pamwamba pake.
Gome 1.
| Zosakaniza za Photoresist | Magwiridwe antchito |
| Chosungunulira | Zimapangitsa kuti photoresist ikhale yamadzimadzi komanso yosasinthasintha, ndipo sizikhudza kwambiri mphamvu ya photoresist. |
| Woyambitsa zithunzi | Imadziwikanso kuti photosensitizer kapena photocuring agent, ndi gawo losavuta kumva kuwala mu zinthu zotsutsa kuwala. Ndi mtundu wa mankhwala omwe amatha kuwola kukhala ma free radicals kapena ma cations ndikuyambitsa ma chemical cross-linking reactions mu ma monomers atatha kuyamwa ultraviolet kapena mphamvu yowoneka ya kuwala kwa wavelength inayake. |
| Utomoni | Ndi ma polima osagwira ntchito, ndipo amagwira ntchito ngati zomangira kuti agwirizanitse zipangizo zosiyanasiyana mu photoresist pamodzi, zomwe zimapatsa photoresist mphamvu zake zamakaniko ndi zamakemikolo. |
| Monomer | Amadziwikanso kuti active diluents, ndi mamolekyu ang'onoang'ono okhala ndi magulu ogwira ntchito omwe amatha kupangidwa ndi polymerizable ndipo ndi mankhwala otsika a molekyulu omwe amatha kutenga nawo mbali mu polymerization reactions kuti apange ma resins okwera kwambiri a molekyulu. |
| Zowonjezera | Amagwiritsidwa ntchito kuwongolera mphamvu zenizeni za mankhwala a photoresists. |
Opanga ma photoresist amagawidwa m'magulu awiri akuluakulu kutengera chithunzi chomwe amapanga: chabwino ndi choipa. Panthawi yolimbana ndi kuwala, pambuyo powonekera ndi kupangidwa, magawo owonekera a utoto amasungunuka, zomwe zimasiya magawo osawonekera. Chophimba ichi chimaonedwa ngati chotsutsa kuwala. Ngati magawo owonekera akadali pomwe magawo osawonekera akusungunuka, utotowo umaonedwa ngati wotsutsa kuwala. Kutengera ndi gwero la kuwala ndi magwero a kuwala, ma photoresist amagawidwanso m'magulu a UV (kuphatikiza ma photoresist abwino ndi oipa a UV), ma photoresist a deep UV (DUV), ma photoresist a X-ray, ma photoresist a electron beam, ndi ma photoresist a ion beam.
Photoresist imagwiritsidwa ntchito makamaka pokonza mapangidwe osalala m'mapanelo owonetsera, ma circuits ophatikizidwa, ndi zida zapadera za semiconductor. Ukadaulo wopanga wa photoresist ndi wovuta, wokhala ndi mitundu yosiyanasiyana ya zinthu ndi ma specifications. Kupanga ma circuits ophatikizidwa m'makampani amagetsi kumapereka zofunikira zolimba pa photoresist yomwe imagwiritsidwa ntchito.
Ever Ray, kampani yopanga zinthu yokhala ndi zaka 20 yodziwika bwino popanga ndi kupanga ma resin otha kuchiritsidwa, ili ndi mphamvu yopangira matani 20,000 pachaka, mzere wonse wazinthu, komanso luso losintha zinthu. Mu photoresist, Ever Ray ili ndi resin ya 17501 ngati gawo lalikulu.
