Abstract
A method for fabricating a signal-separating CFA includes forming a multi-height CFA on a substrate. The multi-height CFA includes a plurality of tall spectral filters and a plurality of short spectral filters. Each of the tall spectral filters is taller than each of the short spectral filters. The method also includes disposing a spectral-blocking layer on the multi-height CFA, and planarizing the spectral-blocking layer to expose a top surface of each of the plurality of tall spectral filters.
