Abstract: A silicon wafer cleaning method is provided. Firstly, a silicon wafer is provided. Then, a polymer cleaning step is performed to clean a surface of the silicon wafer. After the polymer cleaning step, a deionized water/carbon dioxide gas discharging step is performed, so that the charges accumulated on the surface of the silicon wafer can be instantly removed. After the deionized water/carbon dioxide gas discharging step, two or more particle removing steps are performed. In addition, an air-jet step is performed during the time interval between every two sub-steps of a single particle removing step. Consequently, the cleaning efficiency of removing the particles will be enhanced.

Abstract: A microelectromechanical system (MEMS) device, method of operating the MEMS device, and a method of forming the MEMS device are provided. The MEMS device includes a positioning mechanism and a locking mechanism. The positioning mechanism includes a first arm structure having a first surface and a second surface; a second arm structure having a first surface and a second surface; wherein the first surface of the first arm structure faces the first surface of the second arm structure. The positioning mechanism also includes a first actuator disposed adjacent to the second surface of the first arm structure facing away from the second arm structure; and a second actuator disposed adjacent to the second surface of the second arm structure facing away from the first arm structure.

Abstract: Embodiments provide an optical device including a carrier; a light source; a receiving chamber in or on the carrier wherein the receiving chamber is configured to receive an optical element; the optical element received in the receiving chamber; a plurality of actuators; and a waveguide arranged to receive light transmitted from the light source through the optical element. At least one of the receiving chamber and the actuators is arranged and configured to adjust the position of the optical element in the receiving chamber in a first direction perpendicular to the main surface of the carrier and in a second direction in-plane with the main surface of the carrier.
