Plasma Overview

Ionized molecules (atoms)

Plasma is the fourth state of matter.

It refers to the state in which electrons fly out of orbit (ionization). Since molecules (atoms) from which electrons have been removed are unstable, they try to become stable by incorporating other electrons.
Plasma is a state of matter that is [highly reactive]! Taking advantage of the high reaction of plasma, it is diverted to various technologies such as surface modification and cleaning.

Highly Reactive
Molecules and atoms in a highly reactive plasma state undergo unique chemical reactions that cannot be obtained under normal conditions. Surface modification, removal of organic matter, etching, thin film formation, etc. are processes that utilize this phenomenon.
The effects of plasma treatment are introduced on the “Principles of Surface Modification and Cleaning” page.

  • Solid (ICE)

    A state in which molecules form a tight scrum. Solids are stable and have a fixed shape and volume.

  • Liquid (Water)

    • It describes a fluid state of sticking together and separating. While the intermolecular forces remain, the molecules have enough energy to move while still influencing each other.

  • Gas (Steam/ water Vapor)

    A state in which atoms and molecules fly around freely. Each molecule is moving far away and moving at high speed.
