Taking a brief look at MicroElectroMechanical Systems (MEMS), we will guide you through the fabrication stages and show you some applications that they are used for. MEMS can be very simple and not move at all to being immensely complex systems with lots of moving elements being controlled by the system. Starting off with some simple facts we will then show the stages of their fabrication. The basic process of manufacturing MEMS starts with deposition of thin films onto their respective material layers. Then the material is patterned by one of many forms of lithography. The final step in creating MEMS is etching the pattern so that the final product will be the desired shape. MEMS can be created at a relatively low cost because they can be produced in high volumes because of bulk fabrication. MEMS are used for microvalves for controlling gas and liquid, switches, sensors, actuators, and much more!. 22 April 2015. Abstract. . Microelectromechanical Systems (MEMS) are devices that integrate mechanical systems with electronic circuits. Fabrication of MEMS involves the use of specialized micromachining technologies. Device packaging aims to protect from outside damage and varies drastically depending upon application. Different materials used, fabrication techniques, and packaging types will be examined..
