Dummy wafers (also known as test wafers) are primarily used for experimentation and testing, distinguishing them from standard product wafers.
Accordingly, reclaimed wafers are predominantly utilized as dummy wafers (test wafers).

Dummy wafers are frequently employed in production devices to enhance safety at the onset of the production process. They are also used for delivery checks and process evaluations.
Given their frequent use in experiments and tests, the size and thickness of dummy wafers are critical factors in most scenarios.

Wafers treated with film deposition are referred to as film wafers.
Examples of films used (film growth) include isolation films for layer separation, metal films for conductivity, and process materials such as resist and protective films.
