Abstract
A semiconductor structure includes a module with a plurality of die regions, a plurality of light-emitting devices disposed upon the substrate so that each of the die regions includes one of the light-emitting devices, and a lens board over the module and adhered to the substrate with glue. The lens board includes a plurality of microlenses each corresponding to one of the die regions, and at each one of the die regions the glue provides an air-tight encapsulation of one of the light-emitting devices by a respective one of the microlenses. Further, phosphor is included as a part of the lens board.
Claims16
A process for manufacturing semiconductor emitters, the method comprising:
- providing a module that includes a substrate with a plurality of light-emitting devices disposed thereon;
- providing a lens board that has a plurality of transparent microlenses, in which phosphor material is included as a part of the lens board;
- placing an optical glue on each of the transparent microlenses;
- aligning the lens board and the module using alignment marks on the lens board and the module, the aligning performed so that each one of the transparent microlenses is aligned with a respective one of the light-emitting devices;
- and
- adhering the lens board to the module so that the optical glue prevents air gaps between the each of the light-emitting devices and the respective transparent microlenses.
A process for manufacturing a plurality of semiconductor emitters, the process comprising:
- providing a lens board that has a plurality of lenses;
- applying transparent optical glue to each of the plurality of lenses;
- drawing an adherent glue on a substrate, where the substrate has a plurality of light-emitting devices thereon, the adherent glue being drawn between adjacent ones of the light-emitting devices;
- and
- adhering the lens board to the substrate so as to eliminate air bubbles between each of the light-emitting devices and corresponding plurality of lenses.
