What is Microfabrication Technology?

Microfabrication refers to the process of fabricating devices on a microscopic scale, often on the order of micrometers or nanometers.
This technology is pivotal in developing components that require high precision, such as those found in miniaturized electronic devices.

The process typically involves various techniques such as photolithography, etching, and deposition, among others.

Key Techniques in Microfabrication

Several critical techniques are employed in microfabrication, each chosen based on the desired characteristics of the final product.

Photolithography

Photolithography is a core technique in microfabrication.
It involves transferring geometric shapes on a mask to the surface of a substrate.

This method is particularly advantageous for creating complex patterns with high precision.

It is pivotal in the electronics market, where intricate circuit patterns are needed.

Etching

Etching is another essential process in microfabrication.
It involves removing layers from the surface of a substrate to create the desired micro-pattern.

There are two primary types of etching: wet etching, which uses liquid chemicals, and dry etching, which uses gases.

Etching is crucial for defining the fine features of electronic components.

Deposition

Deposition refers to the process of adding thin layers of material onto a substrate.
This method can involve physical vapor deposition (PVD) or chemical vapor deposition (CVD).

Deposition is used to create various thin films essential in electronics, such as those needed for semiconductors.
