WebPECVD showerhead bright spots It is quite common to see PECVD showerhead holes becoming enlarged. This is caused during high-power processing (on an 80 Plus this is typically during plasma cleaning). Any holes which have slightly sharper edges will form an intense discharge over the hole (due to the high fields generated by the sharper edges).
