India, May 7 -- What Is Epitaxial Growth?

Epitaxial growth is a fundamental process in semiconductor manufacturing. It refers to depositing a thin, crystal layer on a crystal substrate, with a specific orientation. This layer closely resembles the crystal structure of the underlying substrate, like stacking identical building blocks.

What Are The Two Types Of Epitaxial Growth?

There are two main types of epitaxial growth distinguished by the material composition of the deposited layer relative to the substrate:

Homoepitaxy: In this type, the deposited layer has the same chemical composition as the substrate. It's like adding another layer of the same material onto an existing foundation. This technique is often used to achieve a purer...
