Flexible light emitting semiconductor device

A flexible article comprising:

• a polymeric dielectric layer having a first major surface with a first electrically conductive layer directly thereon and having a second major surface, a first plane comprising the first major surface, a second plane comprising the second major surface, the dielectric layer disposed within a region between the first and second planes, the dielectric layer having at least one cavity extending from the second major surface toward the first major surface, the first electrically conductive layer comprising an electrically conductive feature substantially aligned with the at least one cavity, and a light emitting semiconductor device supported by the electrically conductive feature, the light emitting semiconductor device disposed outside the region between the first and second planes.

An article comprising:

• a flexible dielectric layer having a first major surface with a first conductive layer directly thereon and having a second major surface, the dielectric layer having at least one cavity extending from the second major surface toward the first major surface, each cavity in the at least one cavity filled with conductive material, the first conductive layer comprising a conductive feature substantially aligned with the at least one cavity, and the first conductive layer further comprising conductive pads disposed adjacent the conductive feature.
