ABSTRACT:
Method for packaging a photo detector integrated circuit (IC) and a pigment filter and resulting package are described. An encapsulated package (e.g., an epoxy-encapsulated package) that includes a first surface is provided. A filter layer is then coated directly onto the first surface. The filter layer provides optical filtering properties (e.g., a predetermined filtering profile) in addition to the filtering provided by the pigment filter.
