Technology

MEMS Technology: MEMS is an emerging technology which uses the tools and techniques that were developed for the Integrated surround industry to build microscopic machines. These machines argon built on standard ti wafers. The real power of this technology is that legion(predicate) machines advise be built at the same epoch crossways the surface of the wafer, with no assembly required. Since it is a photographic-like process, it is erect as easy to build a million machines on the wafer as it would be to build just one. These tiny machines ar befitting ubiquitous, and are quickly finding their way into a kind of commercial and defense applications. there are some(prenominal) different giving categories of MEMS technologies, outlined below: mess Micromachining: mass micromachining is a falsehood technique which builds mechanical elements by showtime with a silicon wafer, and then etching away undesirable parts, and being go away with useful mechanical devices. Typically, the wafer is photo patterned, divergence a tutelary layer on the parts of the wafer that you unavoidableness to keep. The wafer is then submersed into a liquid etchant, like thousand hydroxide, which eats away whatever exposed silicon.

This is a relatively simple and inexpensive falsehood technology, and is well suited for applications which do not require very much complexity, and which are price sensitive. Today, to the senior highest degree all set upon sensors are built with Bulk Micromachining. Bulk Micromachined ram sensors passing play several(prenominal) advantages over tradition al pressing sensors. They cost less, are ! highly reliable, manufacturable, and there is very severe repeatability between devices. all told new cars on the market today have several micromachined pressure sensors, typically used to quantity manifold pressure in the engine. The small size 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, pose it on our website: BestEssayCheap.com
