02. PARTICLE CONTROL WAFER

Particle Control Wafers, commonly known as dust-free wafers. A standard box contains 25 wafers, vacuumed and sealed for protection. These wafers fall into three categories: Test, Monitor, and Prime Grades.

Test and Monitor wafers are designed for research and early production, while Prime Wafers offer exceptional quality with advanced particle control and flatness. They are particularly well-suited for intricate projects such as photolithography or direct IC chip production, playing a crucial role in forming circuit patterns on substrates and manufacturing devices.
