Abstract

Adhesive-free assembly of the substrate (12) and reflector components (16) of a semiconductor die package (10) is achieved by injection molding the reflector (16) onto a surface (22) of the substrate (12) or by molding the reflector (16) separate from the substrate (12) and securing it in place on the substrate (12) through deformation of a portion (36) of the reflector (16) . The reflector (16) may be made reflective either by molding the reflector (16) using a light scattering material or through the addition of a reflective element (20) , such as a piece of foil material that is secured to the reflector (16) . A variety of interchangeable reflective elements (20) having different surface shapes, and thus different light reflecting properties, may be made.
