Dummy wafers (also referred to as test wafers) are primarily utilized for experimental purposes and testing, distinguishing them from standard production wafers.
Reclaimed wafers are predominantly used as dummy wafers (test wafers).

Dummy wafers play a critical role in production equipment to enhance safety at the onset of the production process and are also used for delivery checks and process evaluation.
Given their frequent use in experimentation and testing, the size and thickness of dummy wafers are crucial factors.

Wafers subjected to film deposition are termed film wafers.
Examples of films used include isolation films for layer separation, metal films for conductivity, and various process materials like resist and protective coatings.
