Two part flexible light emitting semiconductor device

A light emitting semiconductor device comprising:

• a flexible dielectric layer having a first major surface with a first conductive layer thereon and having a second major surface with a second conductive layer thereon, the dielectric layer having one or both of a first and second via extending through the dielectric layer and a cavity or a third via extending from the first surface to, or toward, the second surface of the dielectric layer, the first conductive layer comprising conductive features in electrical contact with one or both of the first and second vias, the cavity or third via at least partially filled with conductive material the second conductive layer comprising conductive features in electrical contact with one or both of the first and second vias;
• the cavity, or third via, being configured to receive a light emitting semiconductor.
