Patent ID: 7514279

Claim:
A method for producing an optoelectronic component having a basic housing, which has a cavity, and a semiconductor chip, which is arranged in the cavity and emits and/or receives electromagnetic radiation, the cavity extending from a front side of the basic housing into the basic housing, wherein a reflective filling compound is arranged in the cavity between the semiconductor chip and side walls of the cavity, of which reflective filling compound at least one of its surfaces facing toward the front side of the basic housing is curved like a concave mirror and forms a reflector area for part of the radiation, the method comprising: (a) forming the basic housing with the cavity, (b) positioning the semiconductor chip in the cavity; (c) filling-in a reflective filling compound into the cavity, the reflective filling compound comprising epoxy resin and TiO 2 particles embedded in the epoxy resin, a proportion of TiO 2 particles in the reflective filling compound being between about 10% and 50% by volume; and (d) arranging material and quantity of the reflective filling compound in such a way that (i) relative to a bottom area of the cavity, a filling height (h F ) thereof adjacent to the semiconductor chip is less than a distance between a laterally radiation-emitting and/or radiation-receiving region of the semiconductor chip and the bottom area, and (ii) a surface thereof, as seen from the semiconductor chip, curves concavely in its course towards the side walls of the cavity on account of adhesion force between the material of the reflective filling compound and material of the side walls, and the surface is formed as a reflector for the radiation.
