Abstract
A vertical color filter sensor group formed on a substrate (preferably a semiconductor substrate) and including at least two vertically stacked, photosensitive sensors. In preferred embodiments, the sensor group includes at least one filter positioned relative to the sensors such that radiation that has propagated through or reflected from the filter will propagate into at least one sensor. Preferably, the filter is or includes a layer that has been integrated with the sensors by a semiconductor integrated circuit fabrication process. In other embodiments, the sensor group includes a micro-lens. Other aspects of the invention are arrays of vertical color filter sensor groups, some or all of which include at least one filter or micro-lens, and methods for fabricating vertical color filter sensor groups and arrays thereof.
