Optoelectronic components, such as light-emitting diode components, are known with different housing variants from the prior art. For example, known from the prior art housing having an embedded in a molding body lead frame. For many applications it is desirable to form optoelectronic Bauele ^¬ ments with space-saving as possible housings.

An object of the present invention is to provide an optoelectronic device. This object is achieved by an optoelectronic component with the Merkma ^¬ len of claim 1. Another object of the vorlie ^¬ constricting invention is to provide a method for producing an optoelectronic component. This object is achieved by a method having the features of claim 14. In the dependent claims various developments of Wei ^¬ are indicated.

An optoelectronic component comprises a first conductor frame section, a second conductor frame section and an optoelectronic semiconductor chip. The first lead frame portion and the second lead frame portion each have ^¬ weils on a top. The optoelectronic semiconductor ^¬ chip is on top of the first leadframe portion arranged. The first conductor frame portion, the second Lei ^¬ terrahmenabschnitt and the optoelectronic semiconductor chip are jointly embedded in a molded article. The Obersei ^¬ th of lead frame portions are seen by the optoelectronic semiconductor chip and the molding completely covered.

Advantageously, this optoelectronic component can have very compact external dimensions. In this case, the optoelectronic component is advantageously very mechanically stable due to the embedding of the conductor frame sections and of the optoelectronic semiconductor chip in the common molded body.

The optoelectronic semiconductor chip of the optoelectronic component can be for example a light-emitting semi ^¬ conductor chip or a light-detecting semiconductor chip. In particular, the optoelectronic semiconductor chip with ^¬ can play, be a light emitting diode chip (LED chip). In this case, the optoelectronic component can prop ^¬ nen for example, for backlighting a liquid crystal display, such as a liquid crystal screen of a portable electronic device.

In one embodiment of the optoelectronic component, the optoelectronic semiconductor chip on a side facing the ers ^¬ th leadframe section underside, a first electrical contact surface which is electrically conductively connected to the first lead frame portion. Advantageously, this results in a particularly simple embodiment of the optoelectronic component.

In one embodiment of the optoelectronic component, the optoelectronic semiconductor chip is also arranged on the upper side of the second conductor frame section. The optoelectronic semiconductor chip extends in this

Case as a bridge between the first lead frame portion and the second lead frame portion. Advantageously, the opto-electronic device can thereby be formed with particularly com pact ^¬ dimensions. In one embodiment of the optoelectronic component, the optoelectronic semiconductor chip has on its underside a second electrical contact surface which

is electrically connected to the second lead frame section ver ^¬ connected. Advantageously, a result from the fact be ^¬ Sonder simple electrical contacting of the optoelectronic semiconductor chips ^¬ rule and thus a particularly simple and compact construction of the optoelectronic component.

In one embodiment of the optoelectronic component, the optoelectronic semiconductor chip on a second elekt ^¬ generic contact surface which is comparatively connected using a bonding wire electrically connected to the second lead frame portion. The second electrical contact surface of the opto ^¬ electronic semiconductor ^chip may in this case, for example ^{¬ be arranged} on a side facing away from the lead frame sections top of the optoelectronic semiconductor chip.

In one embodiment of the optoelectronic component, an upper side of the optoelectronic semiconductor ^{chip is at} least partially not covered by the shaped body. The top of the optoelectronic semiconductor chips can form into diesel sem case a radiation passage area of the optoelectronic semiconductor chips ^¬ rule, in particular for example ei ^¬ ne radiation emitting surface. The opto-electronic semi-conductor chip ^¬ of the optoelectronic component is thereby able to emit radiation at its top or to detect radiation.

In one embodiment of the optoelectronic component, a wavelength-converting element is arranged on the upper side of the optoelectronic semiconductor chip. The WEL lenlängenkonvertierende element can be adapted by the optoelectronic semiconductor chip of the optoelectronic component to electromagnetic radiation emitted ^¬ least partially to convert electromagnetic radiation in a wavelength walls ^¬ ren. In one embodiment of the optoelectronic component, the wavelength-converting element is embedded in the shaped body. Advantageously, the optoelectronic component therefore does not have to be equipped with a further external wavelength-converting element. The wavelength-converting element embedded in the shaped body can also form a recess in the shaped body, which serves as a reflector for bundling electromagnetic radiation emitted by the optoelectronic semiconductor chip. Furthermore, in the production of this optoelectronic component, the wavelength-converting element can serve as a spacer and cause protection of a bonding wire connected to the optoelectronic semiconductor chip.

In one embodiment of the optoelectronic component are the tops of opposing lower surfaces of the lead frame portions on an underside of the optoelectronic device ^¬ rule at least partially exposed. The uncovered on the underside of the optoelectronic component undersides of the leadframe sections can thereby form Lötkontakt ^¬ surfaces of the optoelectronic device and are used for electrical contacting of the optoelectronic device. The optoelectronic component may be suitable for example as an SMD for surface mounting by the fact, for example, for surface mounting by How To ^¬ deraufschmelzlöten (reflow soldering).

In one embodiment of the optoelectronic component, the first leadframe section has a first contact recess on its underside. In this case, the second Lei ^¬ terrahmenabschnitt on its underside on a second contact recess. The first contact recess and the second contact recess both adjoin a first edge of the underside of the optoelectronic component. The adjacent to the first edge of the underside of the optoelectronic component contact recesses of the leadframe portions of this optoelectronic device can form Lötkontaktflä ^¬ surfaces of the optoelectronic device. This way net, the opto-electronic component for mounting in a sidelooker arrangement in which the top surface of the optoelectronic semiconductor chip is oriented perpendicular to the mounting plane so that is emitted by the optoelectronic semiconductor chip emitted light in to the mounting plane parallel Rich ^¬ processing. By forming the solder contact ^¬ surfaces of the optoelectronic component as Kontaktausneh- regulations they can form Lötkon ^¬ control structures that ermögli a visual inspection of correct assembly of the optoelectronic component ^¬ chen advantageously simultaneously. The fact that the contact recesses of the optoelectronic component are arranged on the lower sides of the Leiterrahmenab ^{¬ sections} , resulting in the assembly of the optoelectronic component assembly tolerances are advantageously reduced.

In one embodiment of the optoelectronic component, the first leadframe section has on its underside a first further contact recess. The second conductor frame section has a second further contact recess on its underside. Both the first further Kontaktaus ^¬ recess and the second further contact recess are adjacent to a second edge of the underside of the optoelectronic component. Advantageously, this results in a symmetrical configuration of the optoelectronic component. The symmetrical design of the opto electro ^¬ African component, it is possible to arrange the optoelectronic component in two different orientations. As a result, the optoelectronic component can advantageously be used in a particularly versatile manner.

In one embodiment of the optoelectronic component, the contact recesses do not extend completely through the leadframe sections. Advantageously, this allows a particularly simple electrical contacting of the optoelectronic component.

In one embodiment of the optoelectronic component is at the bottom of the optoelectronic component a Protective chip arranged and electrically conductively connected to the first lead frame portion and the second Leiterrahmenab ^{¬ section} . The protective chip is thereby electrically connected in parallel to the optoelectronic semiconductor chip of the optoelectronic component. The protection chip can ^¬ example, a protection of the optoelectronic semiconductor chips of the optoelectronic component from being damaged by electrostatic discharge serve. A method of manufacturing an optoelectronic device comprises the steps of providing a lead frame having a first lead frame portion and a second Lei ^¬ terrahmenabschnitt, each having a top surface for disposing an optoelectronic semiconductor chip on the first lead frame portion and for embedding the first lead frame portion, the second lead frame portion and of the optoelectronic semiconductor chip in the Common a ^¬ men molding. In this case, the upper sides of the leadframe sections are completely covered by the optoelectronic semiconductor chip and the molded body.

This method enables a cost-effective production of an optoelectronic component with very compact external dimensions. The optoelectronic semiconductor chip can be, for example, a light-emitting semiconductor chip or a light-detecting semiconductor chip, in particular, for example, a light-emitting diode chip. The obtainable by the process optoelectronic component can ^¬ example, for use as backlighting for liquid crystal screens in mobile electronic devices are suitable.

In one embodiment, the method comprises the ready ^¬ provide the lead frame comprises a step of forming a first contact recess on an underside of the first lead frame portion and a second contact recess on an underside of the second lead frame portion. Can taktausnehmungen the con- for example, be formed by a Ätzpro ^¬ zesses. The fact that the Kontaktausneh- ments already before embedding the lead frame in the Moldings are applied, the contact recesses can be provided before embedding the lead frame sections in the molding with a coating that improves the solderability of the contact recesses. Thereby, the contact recesses are suitable to the lower surfaces of the lead frame portions of the available by this method optoelectronic device, advantageously for USAGE ^¬ dung as solder pads for electrically contacting the available by the process of the optoelectronic component.

In one embodiment of the method, the contact recesses are applied as blind holes on the undersides of the leadframe sections. Advantageously, the contact recesses in the optoelectronic component obtainable by the method thereby provide a large surface which can be wetted by solder, thereby enabling reliable electrical contacting of the optoelectronic component obtainable by the method.

In one embodiment, the method comprises the ready ^¬ provide the lead frame comprises a step of disposing a coating on a surface of the lead frame. The Be ^¬ coating may for example serve to improve the solderability of the lead frame portions of the lead frame, in particular the wettability of the electrical Kontakt ^¬ orientation obtainable by the process of the optoelectronic component serving portions of the lead frame portions by solder.

In one embodiment of the method, the leadframe is provided with a plurality of further leadframe ^sections . Here all leadframe portions of the lead frame ^¬ be embedded together in the molding. In this case, the method comprises a further step for dividing the shaped body and the leadframe in order to separate the optoelectronic component. The method thereby enables a parallel production of a plurality of optoelectronic components in common processing steps. hereby The cost of fabricating a single optoelectronic device and the time required to fabricate a single optoelectronic device are reduced. In one embodiment of the method, the leadframe is split along a parting plane that extends through the first contact recess and through the second contact recess. Advantageously, the contact recesses in which obtainable by the process opto-electronic components are element characterized opened to side surfaces of the optoelectronic component through, enabling mounting of the available by the procedural ^¬ ren optoelectronic component in an Si delooker arrangement. In one embodiment of the optoelectronic component, the shaped body is formed by means of a molding process. For example, the shaped body can be formed by injection molding (tear molding) or by injection molding (injection molding). Advantageously, the method thereby enables a simple, inexpensive and well reproducible production of the molding.

Fig. 1 shows a schematic perspective view of part of a lead frame 300. Fig. 2 shows a specific ^¬ matic perspective view of the part of Leiterrah ^¬ mens 300 from a different viewing direction. The lead frame 300 may also be referred to as a leadframe. FIGS. 1 and 2 show a first leadframe section 100 and a second leadframe section 200 of the leadframe 300. The lead frame 300 generally includes in Figures 1 and 2, not shown, further Leiterrahmenab ^¬ sections, which are formed as the first lead frame portion 100 and the second lead frame portion 200. Depending on a first lead frame portion 100 and a second Leiterrah ^¬ menabschnitt 200 of the lead frame 300 form a zusammenge ^¬ hearing pair. All leadframe sections of the leadframe 300 are integrally connected in one piece with the same material. connected to each other. In this case, however, the first leadframe sections 100 and second leadframe sections 200 forming a pair are not directly connected to one another, but only via the adjacent further leadframe sections. Also, the pair shown in Figures 1 and 2 of the first lead frame portion 100 and the second Leiterrah ^¬ menabschnitts 200 is not directly connected.

The leadframe 300 is substantially flat and flat and can be made of sheet metal, for example. Openings arranged in the leadframe 300, which may have been applied by means of an etching process, for example, delimit the first leadframe section 100 and the second leadframe section 200 from one another. The first leadframe section 100 has an upper side 101 and an underside 102 opposite the upper side 101. The second leadframe section 200 has an upper side 201 and a lower side 202 opposite the upper side 201. In Fig. 1, the upper sides 101, 201 of the lead frame sections 100, 200 are visible. 2 shows the lower sides 102, 202 of the leadframe sections 100, 200.

The lead frame 300 comprises an electrically conductive material, preferably a metal. For example, the conductor frame 300 may comprise copper. On parts or the entire surface of the leadframe 300, that is, for example, on the upper sides 101, 201 and the lower sides 102, 202 of the leadframe sections 100, 200, as well as in the openings of the leadframe 300, a coating 301 may be arranged, for example, a solderability and / or an opti ^¬ cal reflectivity of the lead frame 300 can improve.

The first leadframe section 100 of the leadframe 300 has on its underside 102 a first contact recess 110 and a first further contact recess 120. The second leadframe section 200 has on its underside 202 a second contact recess 210 and a second further contact recess 220. The contact recesses 110, 120, 210, 220 are respectively in edge regions of the lower sides 102, 202 of the lead frame portions 100, 200 Zvi ^¬ rule at the boundaries of the lead frame portions 100, 200 and other adjacent lead frame portions of the lead frame 300 is located. The contact recesses 110, 120, 210, 220 may extend beyond the leadframe sections 100, 200 shown in FIG. 2 to the respectively adjacent leadframe ^{sections of} the leadframe 300.

The first contact recess 110 and the first further contact recess 120 of the first leadframe section 100 are arranged on opposite sides of the first leadframe section 100. Accordingly, the second contact recess 210 and the second further contact recess 220 are arranged on opposite sides of the second leadframe section 200. In this case, the first contact recess 110 of the first leadframe section 100 and the second contact recess 210 of the second leadframe section 200 are arranged in the mutually opposite arrangement of the first leadframe section 100 and the second leadframe section 200 on a common first side. The first further contact recess 120 of the ERS ^¬ th lead frame portion 100 and the second further Kon ^¬ taktausnehmung 220 of the second lead frame portion are arranged on a common second side.

The contact recesses 110, 120, 210, 220 are in each case embodied as recesses or blind holes, which extend incompletely through the leadframe sections 100, 200, on the undersides 102, 202 of the leadframe sections 100, 200. The contact recesses 110, 120, 210, 220 may have been created at ^¬ example by means of an etching process. The beyond the boundaries of the first lead frame portion 100 and the second lead frame portion 200 to Benach ^¬ disclosed lead frame portions extending Kontaktausneh- rules 110, 120, 210, 220 approximately circular cross-sections may for example each have. In this case, the lower sides 102, 202 of the first lead frame section 100 and the second lead frame section 200 may be attached. arranged parts of the contact recesses 110, 120, 210, 220 each have semicircular cross sections.

The coating 301 of the leadframe 300 preferably also extends to the contact recesses 110, 120, 210, 220.

The first conductor frame portion 100 and the second Leiterrah ^¬ menabschnitt 200 of the lead frame 300 are formed in the example shown in Figures 1 and 2 example, mirror-symmetrical to each other. However, this is not mandatory. It is possible to form the first lead frame portion 100 and the second lead frame portion 200 with different Geo ^¬ geometries and / or different sizes. Fig. 3 shows a schematic sectional side view of the first lead frame portion 100 and the second Leiterrah ^¬ menabschnitts 200 of the lead frame 300 in one of depicting ^¬ development of Figures 1 and 2 in time subsequent processing status.

The lead frame 300 has been arranged on a carrier foil 310. In this case, the lower sides 102, 202 of the leadframe sections 100, 200 face the carrier foil 310. The Trä ^¬ gerfolie 310 may be for example a self-adhesive film adhered to the lower surfaces 102, 202 of the lead frame portions 100, 200 of the lead frame 100th

Instead of the carrier film 310, another carrier can also be used. Preferably, this carrier covers all raised portions of the lower sides 102, 202 of the first lead frame portion 100 and the second lead frame portion 200 in a sealing manner. The carrier can be designed for this purpose, for example with a soft surface, making it possible ^¬ light, the lower surfaces 102, 202 of the lead frame portions 100, 200 of the lead frame 300 easily into the carrier einzudrü ^¬ CKEN.
