I'm hoping someone can provide clues/insight as to what these are. The substrate material is likely glass (SiO2), about as thick as a MEMS cantilever, and are generally not top layers of a 'standard' Silicon IC- they are stand-alone planar structures connected to a ground plane (not shown).
Thanks in advance...
