Dummy wafers, also known as test wafers, are primarily utilized for experimental and testing purposes, differing from standard wafers used in products.
Reclaimed wafers are predominantly employed as dummy wafers (test wafers).

Dummy wafers are frequently utilized in production devices to enhance safety at the outset of the production process and are critical for delivery checks and process evaluation.
Given their role in experimentation and testing, the size and thickness of dummy wafers are crucial factors in most scenarios.

Wafers that undergo film deposition are referred to as film wafers.
Examples of films used include isolation films for inter-layer separation, metal films for conductivity, and process materials like resist and protective films.
