Common Cathode and Anode for Power
Disclosed is a method for a common cathode and anode to
monitor power, by using a single metal pad with a photodiode on the PLC.
Benefits include a reduction in material costs.
Currently, to build power monitor devices with either a
common cathode or a common anode, two different metal layouts on the PLC are
The disclosed method uses one metal layout on the PLC. This
layout contains a photodiode on the PLC that determines the polarity of the
common pad (i.e. determines common cathode or common anode). Symmetric and/or
common metal pads are required between the PLC and the photodiode. Figures 1
and 2 show the metal pads layout on the photodiode. Figure 3 shows multiple
metal pads on the PLC, with a common pad. Figure 4 shows the metal layout on
the PLC with the common pads.
The disclosed method reduces process costs by using one
metal layout on the PLC that fulfills both cathode and anode requirements.
