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

Dummy wafers are frequently employed in production devices to enhance safety at the initial stage of the production process, as well as for delivery inspection and process evaluation.
Given their frequent use in experiments and tests, the size and thickness of dummy wafers are critical considerations.

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