Abstract: A semiconductor package includes a semiconductor die, a redistribution structure and connective terminals. The redistribution structure is disposed on the semiconductor die and includes a first metallization tier disposed in between a pair of dielectric layers. The first metallization tier includes routing conductive traces electrically connected to the semiconductor die and a shielding plate electrically insulated from the semiconductor die. The connective terminals include dummy connective terminals and active connective terminals. The dummy connective terminals are disposed on the redistribution structure and are electrically connected to the shielding plate. The active connective terminals are disposed on the redistribution structure and are electrically connected to the routing conductive traces. Vertical projections of the dummy connective terminals fall on the shielding plate.

Abstract: A radiation-emitting device comprising a substrate, a first electrode and a second electrode, and an emitter layer arranged between the first and second electrode. The emitter layer here comprises a matrix material, 0.5-5% by weight of a radiation emitting emitter and 5-30% by weight of a phosphorescent exciton scavenger. The proportion by weight of the exciton scavenger here is higher than that of the radiation emitting emitter, and the emission maximum of the exciton scavenger is at a shorter wavelength than that of the radiation emitting emitter. In addition, the radiation-emitting device is characterized in that the current efficiency of the emitter layer is increased by at least 10% compared to the current efficiency of an emitter layer without exciton scavenger.
