Dummy wafers, also known as test wafers, are primarily used for experiments and tests and differ from general product wafers.
Reclaimed wafers are predominantly used as dummy or test wafers, offering a sustainable option for experimental applications.

Dummy wafers play a crucial role in production devices to enhance safety at the start of the production process and are essential for delivery checks and process evaluation.
When employing dummy wafers for experiments and tests, their size and thickness are critical factors that significantly impact most applications.

Wafers that undergo film deposition are referred to as film wafers.
Films used (film growth) include isolation films for layer separation, metal films for conductivity, and process materials like resist and protective films.
