Caption: Light micrograph of a MEMS (MicroElectroMechanical System) microphone amplifier wafer. MEMS microphones are installed in nearly all modern smartphones. The image shows the complete amplifier wafer with the connection bond wires, the two wires on the left side connected with the MEMS unit. The amplifier is mounted together with the MEMS wafer in the small housing. Microscopic contrast technique: Polarization contrast. Magnification: 80x when printed 10 centimetres wide.
