Abstract
An array of optical filters having a front side and a back side is disclosed. The array of optical filters includes first and second optical filters and a molding compound. The first and second optical filters each include a substrate having a back surface coplanar with the back side of the molding compound, and a filter layer having a front surface coplanar with the front side of the molding compound. The molding compound covers the sidewalls of the filter substrates and filter layers, and fills gaps between the filters.
