This is a technical document for the construction of a management system for large particle particles in the work environment and on-site.
The "Particle Counter" is a light scattering type microparticle meter manufactured by Airy Technology Co., Ltd., which handles products in the field of contamination control.
In the operational model, it manages local and dynamic operations of the OPC alone, as well as coordinated operations with systems such as deposition machines, overseeing the process management from chamber opening to the insertion of the next lot of substrates.
This document introduces various aspects related to the construction of a management system for large particle contaminants, including the concepts and improvement points of these particle counters, and the size of defects required for optical films in recent years, using diagrams and tables.

■ The size of defects required for optical films in recent years
■ The impact of contamination size on the surface within thin films
■ Contamination size on substrates calculated from required levels
■ The size of contaminants that should be managed in thin film coatings, etc.
