Dummy wafers, also known as test wafers, are primarily used for experimentation and testing, differing from general product wafers.
Accordingly, reclaimed wafers are predominantly used as dummy wafers (test wafers).

Dummy wafers are frequently utilized in production devices to enhance safety at the start of the production process and are used for delivery checks and process evaluations.
Given their experimental and testing roles, the size and thickness of dummy wafers are critical factors in most scenarios.

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 like resist and protective films.
