Abstract
A multi-color light detector includes a first photodiode. The light detector further includes a second photodiode stacked on the first photodiode and defining a via. The light detector further includes a first conductor extending through the via, contacting the first photodiode, and designed to transmit a first signal corresponding to a first light detected by the first photodiode. The light detector further includes a second conductor contacting the second photodiode and designed to transmit a second signal corresponding to a second light detected by the second photodiode.
