Abstract:
An emitter for an LED-based lighting device can incorporate “flip-chip” LEDs, in which all electrical contacts are disposed on the bottom surface of the chip. The emitter base can be a multilayer high-temperature cofired ceramic (HTCC) substrate, with metal traces formed between the layers and vias through the layers to join traces in different layers, thereby providing electrical connectivity to each LED. The paths can be arranged such that current can be supplied independently to different subsets of the LEDs. The top layer of the emitter base is fabricated with exposed vias at the top surface. Metal pads are then printed onto the exposed vias on the top surface, and flip-chip LEDs are bonded to the metal pads, e.g., using solder.

Claim (Index 1):
A method for fabricating an emitter for an LED-based lighting device, the method comprising:\n fabricating a substrate base having a plurality of layers of high-temperature cofired ceramic (HTCC) material, a plurality of metal paths disposed between the layers, and a plurality of vias interconnecting the plurality of metal paths; polishing and cleaning a top surface of the substrate base, wherein top ends of a subset of the plurality of vias are exposed at the top surface; printing a plurality of metal pads on the top surface of the substrate base such that at least some of the metal pads are printed onto the top ends of the subset of the plurality of vias; and bonding a plurality of LEDs to the at least some of the metal pads, wherein at least one of the plurality of LEDs is a flip-chip LED.
