Dummy wafers (also known as test wafers) are primarily used for experiments and testing, differing from standard production 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 start of the production process and are used for delivery checks and process evaluations.
As dummy wafers are often used for experiments and testing, their size and thickness are crucial factors in most scenarios.

Wafers processed 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 resists and protective films.
