Technology

MEMS Technology: MEMS is an emerging engineering which uses the tools and techniques that were developed for the Integrated tidy sum industry to build microscopical machines. These machines argon built on standard ti wafers. The really power of this technology is that legion(predicate) machines fire be built at the same epoch crossways the surface of the wafer, with no forum required. Since it is a scenegraphic-like process, it is erect as easy to build a million machines on the wafer as it would be to build fitting one. These tiny machines argon suitable ubiquitous, and are quickly determination their way into a grade of commercial and defense applications. on that point are some(prenominal) different big categories of MEMS technologies, outlined below: draw Micromachining: mass micromachining is a gathering technique which builds mechanical elements by showtime with a silicon wafer, and then etching forth undesirable separate, and being remaining with useful mechanical devices. Typically, the wafer is photo patterned, divergence a cautionary layer on the parts of the wafer that you unavoidableness to keep. The wafer is then submersed into a liquid etchant, like one thousand hydroxide, which eats away some(prenominal) exposed silicon.

This is a relatively simple and inexpensive finesse technology, and is well suited for applications which do not require practically complexity, and which are price sensitive. Today, to the aged(a) highest degree all assault sensors are built with book Micromachining. stack Micromachined atmospheric wedge sensors allow for some(prenominal) advantages over conventional pressure sensors. They cost less, are highly reliable, manufacturable, and there is truly severe repeatability between devices. only new cars on the commercialize today have several micromachined pressure sensors, typically use to quantity manifold pressure in the engine. The small coat and high reliability of micromachined pressure sensors make them ideal for a variety of medical applications as well. Surface Micromachining: While Bulk micromachining creates devices by etching into a wafer,...If you want to get a in full essay, point it on our website: Orderessay
