Photo active compound 원리
WebPhoto acid generators or cationic photoinitiators are chemical compounds which release, through decomposition, cationic species, proton, upon irradiation from light source. They … WebPhotoactive compound rich, highly diluted resists often show a accelerated ageing, sometimes accompanied by particle formation in the resist. Therefore, for resist film thicknesses < 500 nm, we recommend the AZ ® ECI 3007 for maximum adhesion or thermally stable high resolution AZ ® 701 MiR.
