MEMS devices often need a silicon layer that can be etched into accurate mechanical structures while staying electrically isolated from the substrate. SOI gives this advantage by using a defined top silicon layer, a buried oxide layer, and a handle wafer.
SOI wafer is used when a semiconductor structure needs a controlled silicon device layer separated from the handle substrate by a buried oxide layer. This structure helps reduce leakage, parasitic capacitance, and substrate interference, making it useful for advanced ICs, MEMS, RF devices, photonics, sensors, and power-related structures.
A wafer COA should include the material identity, wafer specifications, measured inspection results, test method references, batch information, packing details, and approval record. It should not be a simple delivery note.
