Dummy wafers (also known as test wafers) are primarily utilized for experiments and testing, differing from standard wafers intended for products.
Consequently, reclaimed wafers are predominantly used as dummy wafers (test wafers).

Dummy wafers are frequently employed in production devices to enhance safety at the start of the production process, as well as for delivery checks and process evaluations.
Given their use in experiments and testing, the size and thickness of dummy wafers are crucial factors.

Wafers processed with film deposition are termed film wafers.
Examples of films used (film growth) include isolation films for layer separation, metal films for conductivity, and process materials like resist and protective films.
