MEMS is an emerging technology which uses the tools and techniques that were developed for the Integrated band industry to build microscopic machines. These machines argon built on standard silicon wafers.
The real power of this technology is that legion(predicate) machines can be built at the same epoch across 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 are becoming ubiquitous, and are quickly finding their way into a manikin of commercial and defense applications.
there are some(prenominal) different broad categories of MEMS technologies, outlined below:
mess Micromachining:
mass micromachining is a fabrication technique which builds mechanical elements by showtime with a silicon wafer, and then etching away undesirable parts, and being left with useful mechanical devices. Typically, the wafer is photo patterned, divergence a protective 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 any exposed silicon.
This is a relatively simple and inexpensive fabrication technology, and is well suited for applications which do not require much complexity, and which are price sensitive.
Today, to the senior highest degree all storm sensors are built with Bulk Micromachining. Bulk Micromachined pressure sensors offer several advantages over traditional pressure sensors. They cost less, are highly reliable, manufacturable, and there is very severe repeatability between devices.
All 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, order it on our website: Orderessay
