MODEL RELEASED. MEMS production. Tweezers being used by a clean room technician to place a MEMS (microelectromechanical systems) device on a microscope mount. This is a mount for a scanning electron microscope. The microscope and screen are seen in the background. MEMS devices are constructed on a microscopic scale using technologies such as wet and dry etching and thin film deposition. Applications include sensors and optical displays. Materials used to construct MEMS devices include silicon and polymers such as plastics. Due to their small size, microscopes have to be used to examine and handle MEMS devices.
