Paper Abstract

In this study, we have developed a new set of cyan, magenta and yellow (CMY) dyed color filter materials to meet the need of digital photography applications. These new color filter materials consist of a dye, a photo sensitive polymer binder, photo initiators, and acrylic monomers in addition to safe solvents such as propylene glycol methyl ether (PGME) which allow deposition of thin film layers by standard spin-on coating techniques. CMY materials share many desirable properties with standard photoresists, e.g., excellent coating quality, thin film uniformity, and good adhesion to semiconductor substrates. They work as negative resists and are sensitive to i-line UV light with photo speed of 300 mJ/cm2 and below. We have shown, for example, that a 1 micrometers film exposed and developed will exhibit high- resolution feature sizes of 3 micrometers pixels and below. These CMY materials have excellent thermal and light stability and good color characteristics.
