Dummy wafers, also known as test wafers, are primarily used for experiments and testing, distinct from general product wafers.
As a result, reclaimed wafers are mostly utilized as dummy wafers for testing purposes.

Dummy wafers enhance safety in the initial stages of production and are crucial for delivery checks and process evaluations.
Given their experimental use, the size and thickness of dummy wafers are typically critical factors.

Wafers processed with film deposition are referred to as film wafers.
Examples of film growth include isolation films for inter-layer insulation, metal films for conductivity, and process materials like resist and protective films.
