Abstract
Image sensors are provided having a plurality of photodetectors in a detector layer Optionally, an optically transparent substrate is provided for a rear-illuminated sensor architecture. The photodetectors may be arranged in three or more arrays. Typically, each array is contiguous and is associated with light of a different color and/or wavelength. In addition, the arrays may be coplanar, or, in the alternative, located at increasing distances from a light-receiving surface in an at least partially nonoverlapping manner. Also provided are image sensor packages.
