What is Microfabrication?

Microfabrication is a technique that makes use of semiconductor manufacturing processes such as ion etching, oxidation, diffusion and sputtering in combination with highly specialized micromachining techniques for faster and efficient production. 

This machining occurs in the range of 1-100 micrometers in different sizes, where both the mechanical parts and the electronics that control them are built into the same piece of silicon material.

Micro-Electromechanical System - MEMS is a miniature machine which is also a part of Microfabrication that has both mechanical and electronic components. The physical dimension of a MEMS can range from several millimeters to less than one micrometer, a dimension many times smaller than the width of a human hair.

MEMS Fabrication are made up in the application of the following steps, normally several times during the manufacturing. The process starts with a polished silicon the substrate wafer that goes through these steps such as:

Doping,

Micromachining,

Thin film growth or Deposition,

Lithography and

Etching.

Mems Fabrication is the way of fabricating smaller structures of several micrometre scales and much smaller. Historically, the earliest microfabrication processes that are used for integrated circuit fabrication, also known as "semiconductor manufacturing" or "semiconductor device fabrication".

Microfabrication Technologies are primarily made from the micro-electronics industry, and the devices are made on silicon wafers even though glass, plastics and many other substrates are also used in the process.

Micromachining, semiconductor processing, semiconductor fabrication, microelectronic fabrication, MEMS fabrication and integrated circuit technology are terms that are used instead of microfabrication, but microfabrication is the broad and general term for all.

Features Of Microfabrication

There are several features of Microfabrication, and some of them are:

1. Patterning It is often desirable to pattern a film into distinct features or to form openings (or vias) in some of the layers. These features are on the micrometer or nanometer scale and the patterning technology is what defines microfabrication.

2. Microforming is a microfabrication method of microsystem or of microelectromechanical system (MEMS) "parts or structures with at least two dimensions that are in the submillimeter range.

3. LIGA: a german acronym for Lithographie Galvanoformung Abformung is a process used to create high aspect ratio using x-rays or relatively low aspect ratio structures using UV rays the steps involves deposition of Thick resist layer (PMMA) onto metal surface.

4. Etching: Etching is the removal of some portion of the thin film or substrate. The substrate is opened up to an etching (such as a plasma or acid) which would chemically or physically attack the film until it is removed.

Benefits of Microfabrication 

There are several benefits of microfabrication, and some of them are;

1. Faster production time of fabrics.

2. Patterning of fabrics are done in production of the fabric

3. Lesser cost of production.

4. Much safer than traditional fabrication methods
