The present invention discloses a thin-film light-emitting device including a charge generating junction layer and a method of fabricating the thin-film light-emitting device. The thin-film light-emitting device including a charge generating junction layer according to one embodiment of the present invention includes a negative electrode; at least one light-emitting unit formed on the negative electrode and including a charge generating junction layer, an electron injection/transport layer, a thin-film light-emitting layer, and a hole injection/transport layer in a sequential order; and a negative electrode formed on the light-emitting unit. In the thin-film light-emitting device of the present invention, the charge generating junction layer has a layer-by-layer structure in which a p-type semiconductor layer and an n-type semiconductor layer are formed, and the concentration of oxygen vacancies at the interface between the p-type and n-type semiconductor layers is adjusted by annealing the n-type semiconductor layer.

An organic substrate and method of making with optimal thermal warp characteristics is disclosed. The organic substrate has one or more top layers and one or more bottom layers. A chip footprint region is a surface region on each of the top and bottom layers that is defined as the projection of one or more semiconductor chips (chips) on the surface of each of the top and bottom layers. One or more top removal patterns are located on and may or may not remove material from the surface of one or more of the top layers within the chip footprint region of the respective top layer. One or more bottom removal patterns are located on and remove material from the surface of one or more of the bottom layers outside the chip footprint region of the respective bottom layer. The removal of the material from one or more of the top layers and/or bottom layers changes and optimizes a thermal warp of the organic substrate. In some embodiments, a Shape Inversion Temperature (SIT) of the substrate is made equal to or above a reflow temperature.

An imaging element according to an embodiment of the present disclosure includes: a first electrode and a second electrode facing each other; and a photoelectric conversion layer including a p-type semiconductor and an n-type semiconductor, and provided between the first electrode and the second electrode, in which the photoelectric conversion layer has an exciton charge separation rate of 1×10.sup.10 s.sup.−1 to 1×10.sup.16 s.sup.−1 both inclusive in a p-n junction surface formed by the p-type semiconductor and the n-type semiconductor.
