Abstract

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