Dummy wafers, also known as test wafers, are specifically utilized for experimental and testing purposes, setting them apart from standard wafers used in production.
Reclaimed wafers find their primary application as dummy wafers or test wafers, reflecting their adaptability in various testing scenarios.

In production devices, dummy wafers are crucial for enhancing safety at the onset of production processes and are essential for delivery checks and process evaluations.
Given their frequent use in experimentation and testing, the size and thickness of dummy wafers are often critical parameters.

Wafers that undergo film deposition processes are referred to as film wafers.
Film wafers can include a variety of coatings-such as isolation films for layer separation, metal films for conductivity, and process materials like resist and protective films-each serving distinct purposes.
