During wafer etching, loose conductive particles need to be collected such as to not cause circuitry failures later in the process.  Commonly, yttrium oxide is used as an ultra-pure coating to capture and retain the particulates.  The interior process area is coated with Yttria using a method to produce a high surface roughness which can be left in the as-sprayed condition.
