    摘要: An optoelectronic component having a basic housing or frame (12) and at least one semiconductor chip (20), specifically a radiation-emitting or -receiving semiconductor chip, in a cavity (18) of the basic housing. In order to increase the efficiency of the optoelectronic component (10), reflectors are provided in the cavity in the region around the semiconductor chip. These reflectors are formed by virtue of the fact that a filling compound (28) filled at least partly into the cavity (18) is provided, the material and the quantity of the filling compound (28) being chosen in such a way that the filling compound, on account of the adhesion force between the filling compound and the basic housing, assumes a form which widens essentially conically from bottom to top in the cavity, and the conical inner areas (30) of the filling compound serve as reflector.

    摘要: Disclosed is a radiation emitting and/or receiving semiconductor component comprising at least one radiation emitting and/or receiving semiconductor chip (1), which is disposed in a recess (2) of a housing base body (3) and is there encapsulated with an encapsulant (4) that is readily transparent to electromagnetic radiation emitted and/or received by the semiconductor chip (1). The recess (2) comprises a chip well (21) in which the semiconductor chip (1) is secured, and a trench (22) that runs at least partway around the chip well (21) inside the recess (2), such that between the chip well (21) and the trench (22) the housing base body (3) comprises a wall (23) whose apex, viewed from a bottom face of the chip well (21), lies below the level of the surface of the housing base body (3) from which the recess (2) leads into the housing base body (3), and the encapsulant (4) extends outward from the chip well (21) over the wall into the trench (22). A corresponding housing base body is also disclosed.
