Abstract

A color filter array for a solid-state imaging device is disclosed. The color filter array is of the "wash-off" type wherein the individual filter elements are formed by dyeing tiny islands of a dyeable composition. As a barrier layer, the color filter array of the present disclosure uses a photocrosslinkable dye-impermeable polymer. The barrier is coated over a set of filter elements. A method of making the described solid-state device is also disclosed.
