Abstract

A method for producing an optoelectronic semiconductor component includes providing a carrier; arranging at least one optoelectronic semiconductor chip at a top side of the carrier; shaping a shaped body around the at least one optoelectronic semiconductor chip, wherein the shaped body covers all side areas of the at least one optoelectronic semiconductor chip, and wherein a surface facing away from the carrier at the top side and/or a surface facing the carrier at the underside of the at least one semiconductor chip remains substantially free of the shaped body or is exposed, and removing the carrier.

Claims (13)

1. A method of producing an optoelectronic semiconductor component comprising:

providing a carrier;

arranging at least one optoelectronic semiconductor chip at a top side of the carrier;

shaping a shaped body around the at least one optoelectronic semiconductor chip, wherein 1) the shaped body covers all side areas of the at least one optoelectronic semiconductor chip, 2) a surface facing away from the carrier at the top side and/or the surface facing the carrier at the underside of the at least one optoelectronic semiconductor chip remains free of the shaped body or is exposed, 3) at least one plated-through hole with an electrically conductive material is produced before or after the shaping-around process for each semiconductor chip, 4) the plated-through hole is arranged laterally spaced apart from an assigned semiconductor chip and the plated-through hole completely penetrates through the shaped body, and 5) in the plated-through hole extends form a top side of the shaped body to an underside of the shaped body, and

removing the carrier.

2. The method according to claim 1 , wherein the shaped body comprises a matrix material and light-reflecting particles are introduced into the matrix material such that the shaped body appears white.

3. The method according to claim 2 , wherein the matrix material contains silicone or consists of silicone and the light-reflecting particles consist of titanium oxide.

4. The method according to claim 1 ,

wherein

a multiplicity of optoelectronic semiconductor chips are arranged at the top side of the carrier; and

each semiconductor chip is provided during operation to generate electromagnet radiation in a wavelength range having a peak wavelength assigned to the semiconductor chip, wherein peak wavelength of each of the semiconductor chips deviates from an average value of peak wavelengths of all the optoelectronic semiconductor chips by at most +/−2%.

5. The method according to claim 4 , wherein a common phosphor layer is disposed downstream of the optoelectronic semiconductor chips at their top side or their underside before or after shaping.

6. The method according to claim 1 , wherein an electrically conductive connection is produced between the plated-through hole and the assigned semiconductor chip, which connection is electrically conductively connected to the surface facing away from the carrier at the top side of the semiconductor chip and extends at the top side of the shaped body.
