- Radiation passage area S borders and with the associated components, which the radiation passage area S
- the first barrier layer 1 is applied, for example, by a method described here.
- Conversion material the actual value of a light characteristic is compared with a target value and the application of conversion material is stopped as soon as the actual value is within the setpoint within a predefined fault tolerance
- the semiconductor device then comprises a first one
- Radiation passage area S is applied and a
- Conversion element 3 which is arranged between the first barrier layer 1 and the second barrier layer 2.
- the two barrier layers can thereby be interconnected with each other and with the conversion element 3 in each case cohesively.
- Radiation passage area S facing away from the top of the first barrier layer 1 forms a contact area between the first barrier layer 1 and the second
- Contact area 12 surrounds the conversion element 3 in
- this comprises at least one further conversion element 3 which is arranged on the upper side of the second barrier layer 2 remote from the radiation passage area S, and at least one further barrier layer 2 the upper side of the further upper side facing away from the second barrier layer 2 Conversion element 3 x and at the top of the second
- Barrier layer 2 is arranged, wherein the second
- the adjacent barrier layers 2, 2 x are in another contact area 12 x in direct contact with each other , where the contact area is between the adjacent ones
- Conversion element 3 x completely surrounds in lateral directions.
- the enclosed further conversion element 3 x can in each case be in direct contact with the adjacent barrier layers 2, 2 x .
- FIG. 2 shows a radiation-emitting optoelectronic semiconductor component, FIG. which is implemented in the so-called “chip in a frame” (CIF) construction.
- a “chip in a frame” component has a shaped body as the housing body 6, which may be formed, for example, with a silicone and / or an epoxy resin.
- the semiconductor device in this case comprises the
- Housing body 6 is embedded, which has a cavity 61 for the chip.
- Radiation-emitting semiconductor chips 4 can in this case directly adjoin the housing body 6, for example
- Radiation reflective may be formed.
- Top connected to the contacting element 41 which is formed, for example, radiation-permeable and may include a transparent conductive oxide.
- a contact element such as a bonding pad 46, that is
- Housing body 6 extends to a through hole 44. At the contacting element 41 facing top of the radiation-emitting semiconductor chip 4 is the
- radiation-permeable envelope body 5 is formed, which is designed here as a curved encapsulation. Due to the curvature of the potting, a probability of the emission of electromagnetic radiation is increased. At the side facing away from the wrapping body 5 underside of
- the arched cladding body 5 further ensures that the distance between the radiation-emitting semiconductor chip 4 and the conversion element 3 is increased, so that an excessive radiation density at the conversion element 3 is avoided. In this way, the described design for the use of sensitive conversion materials such as quantum dot converter is particularly suitable.
- the arched cladding body 5 allows homogenization of the radiated mixed light with respect to the color of the light depending on the viewing angle.
- the first barrier layer 1 is in direct contact with areas of the radiation-permeable covering body 5 and of the housing body 6 and of the contacting element 45. In particular, the first barrier layer 1 covers the first barrier layer 1
- the use of elastic materials to form the first and second barrier layers 1, 2 moreover allows the conversion element to follow the curvature of the covering body 5.
- the housing body 6 laterally spaced from the radiation-emitting semiconductor chip 4 and the cavity of the housing body 6 is formed
- the first barrier layer 1 is partially within the cavity and is thus more mechanical
- the second barrier layer 2 may be formed planar. With others
- the first barrier layer 1 extends along the
- the semiconductor chip 4 remote from the outer surface forms the radiation passage area S. Furthermore, the first barrier layer 1 is in direct contact with the housing body 6.
- the conversion element 3 is
- Semiconductor chip 4 is arranged and covers the opening 62 of the cavity 61 of the housing body 6 to at least 95%. This is also in this embodiment
- the contact region 12 is between the first barrier layer 1 and the second
