Abstract:
1. An optoelectronic semiconductor component arranged in a surrounding atmosphere, the semiconductor component comprising: a housing base body having a recess, the recess extending into the housing base body from a front side of the housing base body; at least one radiation emitting semiconductor chip disposed in the recess; and an encapsulant at least partially filling the recess; wherein the recess has a bottom surface remote from the front side of the housing base body and the recess is bounded laterally by an inner side surface of a wall, the inner side surface extending from the front side of the housing base body to the bottom surface of the recess; wherein the radiation emitting semiconductor chip is mounted on the bottom surface of the recess and is laterally surrounded by the inner side surface of the wall; wherein the encapsulant covers the semiconductor chip and is substantially transmissive to an electromagnetic radiation emitted by the semiconductor chip; wherein the encapsulant contains a silicone-based material; wherein the wall is made from a plastic material such that the inner side surface is a surface of the plastic material which extends from the front side of the housing base body to the bottom surface of the recess on which the radiation-emitting semiconductor chip is mounted and provides an interface where the encapsulant bonds to the plastic material, said interface extending from the front side of the housing base body to the bottom surface of the recess; wherein the wall is shaped such that a shaded subarea is formed which extends all the way around the at least one semiconductor chip and which is not directly illuminated by the radiation emitted from the radiation emitting semiconductor chip; wherein the shaded subarea is at least partially covered by the encapsulant and the encapsulant extends from the shaded subarea to the semiconductor chip and covers the semiconductor chip; wherein the surrounding atmosphere, the encapsulant and the housing base body define a three-phase boundary; and the shaded subarea is disposed at a top margin of the wall in such fashion that the three-phase boundary between the surrounding atmosphere, the encapsulant and the housing base body extends all the way around the at least one semiconductor chip entirely within the shaded subarea which is not directly illuminated by the radiation emitted from the radiation emitting semiconductor chip.
