What Is Metallization Process

Metallization is a general term that refers to the application of a metal coating to another metallic or non-metallic surface. Depending on the desired result, the coating can consist of metals such as zinc, gold, aluminum or silver.

What is the use of metallization?

To reduce interconnection resistance and save area on a chip, multilevel metallization, as discussed in this section is also used. Metallization is also used to produce rectifying (Schottky barrier) contacts, guard rings, and diffusion barriers between reacting metallic films.

What are the different techniques of metallization?

Metallization is deposited by either physical vapor deposition (PVD) or chemical vapor deposition (CVD). The most common forms of physical vapor deposition (PVD) are evaporation, e- beam evaporation, plasma spray deposition, and sputtering.
