An SEM image of a 300 μm by 300 μm microheater, dotted with microparticles of the TL material Mg2SiO4. The heater comprises a 160 nm Pt resistor on a 200 nm LPCVD low-stress silicon nitride platform; a cap layer of PECVD nitride protects the resistor’s Cr adhesion layer from attack during the KOH platform release etch. The scuffing visible on the gold contact pad at bottom is from the use of a microprobe to make electrical contact during testing24. TL, thermoluminescence.
