The disclosure facilitates testing and binning of multiple LED chip or other optoelectronic chip packages fabricated on a single semiconductor wafer. The testing can take place prior to dicing. For example, in one aspect, metallization on the front-side of a semiconductor wafer electrically connects together cathode pads (or anode pads) of adjacent sub-mounts such that the cathode pads (or anode pads) in a given column of sub-mounts are electrically connected together. Likewise, metallization on the back-side of the wafer electrically connects together anode pads (or cathode pads) of adjacent sub-mounts such that the anode pads (or cathode pads) in a given row of sub-mounts are electrically connected together. Probe pads, which can be located one or both sides of the wafer, are electrically connected to respective ones of the rows or columns. |
