Patent ID: 7365371

Claim:
A submount for mounting an LED, the submount comprising: a substrate having a planar upper surface; a die attach pad on the upper surface of the substrate, the die attach pad configured to receive an LED chip; a first meniscus control feature on the substrate, the first meniscus control feature comprising a first patterned film on the planar upper surface of the substrate surrounding the die attach pad, defining a first encapsulant region of the upper surface of the substrate, and being configured to limit the flow of a liquid encapsulant material across the substrate, wherein a portion of the planar upper surface of the substrate within the first encapsulant region is exposed; and a second meniscus control feature on the substrate, the second meniscus control feature comprising a second patterned film on the planar upper surface of the substrate surrounding the first encapsulant region, exposing and defining a second encapsulant region of the upper surface of the substrate including an exposed portion of the planar upper surface of the substrate between the first meniscus control feature and the second meniscus control feature, and being configured to limit the flow of a liquid encapsulant material across the substrate.
