Dummy wafers, also known as test wafers, are primarily used in experimental and testing phases, distinct from regular production wafers.
Consequently, reclaimed wafers are predominantly repurposed as dummy wafers for testing.

Dummy wafers are integral to enhancing safety at the start of production processes and are utilized for delivery checks and process evaluations.
Given their experimental and testing usage, the size and thickness of dummy wafers are critical factors in most applications.

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.
