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

Dummy wafers are frequently employed in production devices to ensure safety at the outset of the production process and are used for delivery checks and process evaluations.
Given their experimental and testing usage, the size and thickness of dummy wafers are crucial factors in many situations.

Wafers processed with film deposition are termed 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.
