Abstract: A method of making a light sensor module includes connecting a light sensing circuit to an interconnect on a substrate, and forming a cap. The cap is formed by producing a cap substrate from material opaque to light to have an opening formed therein, placing the cap substrate top-face down, dispensing a light transmissible material into the opening, compressing the light transmissible material using a hot tool to thereby cause the light transmissible material to fully flow into the opening to form at a light transmissible aperture, and placing the cap substrate into a curing environment. A bonding material is dispensed onto the substrate. The cap is picked up and placed onto the substrate positioned such that the light transmissible aperture is aligned with the light sensing circuit, with the bonding material bonding the cap to the substrate to thereby form the light sensor module.

Abstract: In a DC-DC converter, a layout is designed to enable utilization the conductive trace connecting the converter output node to an output bump at which the load is attached as a sense resistor. The layout forces the output current down into lower metallization levels of an interconnect layer reaching the converter output node before the output current flows up into this conductive trace and out through the output bump. The conductive trace includes resistive pillars connected in parallel or series between the lower metallization levels and a top metallization layer of the conductive trace, with these resistive pillars being substantially greater in resistance than the lower metallization levels and the top metallization layer of the conductive trace.
