MICRO-FABRICATION TECHNIQUES AND NANO TECHNIQUES Mpyanews
What Is Micro-Fabrication?
Micro-fabrication refers to the process of creating miniaturized structures, typically on the micrometer or nanometer scale. It involves techniques that enable the precise manipulation of materials at very small scales to produce devices such as microchips, sensors, and MEMS (Micro-Electro-Mechanical Systems). Common micro-fabrication techniques include photolithography, etching, deposition, and bonding.
These processes are fundamental in the production of semiconductors and integrated circuits, which power virtually every modern electronic device, from smartphones to computers. Micro-fabrication techniques are also essential in the development of advanced materials and systems used in a variety of industries, including aerospace, automotive, and healthcare.
Understanding Nanotechnology
Nanotechnology involves the manipulation of matter on an atomic or molecular scale, typically within the range of 1 to 100 nanometers. It is a multidisciplinary field that spans chemistry, physics, materials science, and engineering. Nanotechnology has led to revolutionary advancements in medicine, energy, electronics, and environmental protection.
In nanotechnology, materials exhibit unique properties that emerge only at the nanoscale. These properties, such as increased strength, improved conductivity, and enhanced chemical reactivity, are leveraged to create new types of materials and devices that outperform their larger counterparts.
