Abstract:. MEMS . technology consists of microelectronic elements, actuators, sensors, and mechanical structures built onto a substrate, which is usually silicon. They are developed using microfabrication techniques: deposition, patterning, and etching. The most common forms of production for MEMS are bulk micromachining, surface micromachining, and HAR fabrication. It. is . a simple way to reveal microstructure. . of metallic alloys.

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.. Wet chemical etching: isotropic.. Anisotropic etching of crystalline Si.. Dry etching overview..
