Micromachining Technology For Mems

The term micromachining usually refers to the fabrication of micromechanical structures with the aid of etching techniques to remove part of the substrate or a thin film. Lecture series on mems microsystems by prof.

Micromachining technology for mems. Lecture 10 micromachining technology for mems. Kovacs bulk micromachining of silicon pp. This technology can also be used for the manufacture of thin film solar cells. A mems device consists of 3 dimensional properties which. Mems has several distinct advantages as a manufacturing technology. Surface micro machining can be seen in action in the following mems microelectromechanical products. Any micromachining technique removes a part of a bulk substrate or of a thin film using various etching methods. This book presents advances in micromachining technology. Microelectromechanical systems mems also written as micro electro mechanical microelectromechanical or microelectronic and microelectromechanical systems and the related micromechatronics and microsystems is the technology of microscopic devices particularly those with moving partsit merges at the nano scale into nanoelectromechanical systems nems and nanotechnology. This lecture was given in the spring 2014 introduction to mems cnm course taught as a dual credit enrollment class at atrisco heritage academy high school in albuquerque new mexico. Surface micromachining builds microstructures by deposition and etching structural layers over a substrate. Silicon has excellent mechanical properties making it an ideal material for machiningan early silicon pressure sensor was made by honeywell in 1962 using isotropic etching. Micromachining is used to fabricate three dimensional microstructures and it is the foundation of a technology called micro electro mechanical systems mems. Santiram kal department of electronics electrical communication engineering iitkharagpur. Semiconductor micromachining is the main technology for mems implementation.

Williams etch rates for micromachining processing pp. In the first place the interdisciplinary nature of mems technology and its micromachining techniques as well as its diversity of applications has resulted in an unprecedented range of devices and synergies. Senturia chapter 3 microfabrication todays lecture tools needed for mems fabrication photolithography review crystal structure of silicon bulk silicon etching techniques. Bulk micromachining and surface micromachining are two major categories among others in this field. Silicon grown either as a monocrystal or as a polycrystal is the familiar material for micromachining performed in this case with standard techniques for silicon processing. Mems stands for micro electro mechanical system an integrated system of mechanical and electro mechanical devices and structures manufactured using micro fabrication techniques.
