What is microfabrication?

microfabrication and micromachining are terms that describe technologies and processes used in the production of microscopic structures or equipment. These structures can range from the size of human hair to less than one human cell. The ability to build a device that has caused technological progress on computers, consumer electronics, green energy technology and many other fields. Microphabrication techniques differ very much depending on the assembly of the device. A micrometer, often known as a micron, is a thousandth of a millimeter. There are 25,400 microns per inch. Nanotechnology is similar to a field, but deals with even smaller components. The inventions of the transistor and the integrated circuit in the 40s and 50s of the 20th century caused a miniaturization trend in electronics. As microfabricated tape, smaller and more complicated integrated circuits were built, allowing to build powerful microchips. Small machines known as microelectromechanical systems can be found in many arrangementsOutgoing, including smartphones and Carbags Sensor Car. Fuel cells and solar panels also use microfabricated parts. Microfabrication techniques and technologies were used in research applications in fields from microbiology to particle physics.

The techniques used in the process of microphabrication depend on the industry and the desired result. Most techniques are approaches from top to bottom, which means that they start with a larger component, such as silicon wafer, and remove it until the final structure is formed. Examples of techniques from top to bottom used on the microscopic level include cutting, polishing and etching.

MANUFAC from below is mostly experimental field. In the bottom -up approach, smaller items such as atoms or molecules are used to create a larger system or device. Bottom -up techniques are used in applications designed to imitate biological stringktur or functions.

Many techniques used in microfabrication are borrowed from other disciplines. The fields of photographs, optics and physics contributed to microtechnology. Some traditional manufacturing techniques, such as injection, have been miniaturized and used in microfabrication.

Regardless of the techniques used, production represents a unique challenge at the microscopic level. Small size means that one piece of dust can cause unnecessary equipment. Microphabrication laboratories are rooms designed to control air particles such as dust and microbes. Workers must wear protective clothing in these rooms to prevent contamination of the formed microscopic parts.
