Dummy wafers, also known as test wafers, are specifically designed for experimental and testing purposes, distinguishing them from standard product wafers.
As such, reclaimed wafers are predominantly used as dummy wafers (test wafers).

Dummy wafers are often employed in production devices to enhance safety at the start of the production process and are used for delivery checks and process form evaluation.
Given their frequent use in experiments and tests, the size and thickness of dummy wafers are critical factors.

Wafers processed with film deposition are known as film wafers.
Examples of films used include isolation films for layer separation, metal films for conductivity, and process materials such as resist and protective films.
