CMOS-integrated flip-chip, micro-pixel InGaN LED arrays for on-chip microfluorimetry

Abstract

4times16 arrays of micro-pixellated InGaN LEDs, each of diameter 72 mum, have been flip-chipped onto CMOS driver backplanes which also contain single-photon avalanche photodiodes. Pattern-programmable control is demonstrated in continuous and nanosecond modes. Such devices show promise as miniaturized excitation and detection systems for microfluorimetry studies.
