Combining to the non VOC properties, this dibasic ester solvent is an excellent alternative to traditional product. For example, Rhodiasolv ® RPDE can substitute acetone (highly VOC solvent in Europe) in cleaning operation. This solvent can replace isophorone and glycol ether in order to reduce hygiene & environment impact for coil coating.
PGMEA is the solvent/thinner of almost all AZ ® and TI photoresists due to its low vapor pressure and its suppression of particle formation in the (further diluted) resist. Additionally, PGMEA is often used for edge bead removal, since its low vapor pressure prevents further thinning of the coated resist film.
