Abstract:
An illuminator (1) has bare semiconductor die light emitting diodes (7) on pads (11) of Ag/Ni/Ti material. A Si wafer (13) has a rough upper surface, and this roughness is carried through an oxide layer (12) and the pads (11) to provide a rough but reflective upper surface of the pads (11), thus forming a diffuser. Epoxy encapsulant (9) is deposited in a layer over the diodes (7) and the pads (11), and it is index matched with a top diffuser plate (8) of opal glass.
