Dummy wafers, also known as test wafers, serve primarily in experimental and testing capacities, distinct from wafers used in final product manufacturing.
Consequently, reclaimed wafers find their primary application as dummy wafers or test wafers, providing an economical solution for experimentation.

In production settings, dummy wafers are crucial for enhancing safety at the onset of production and for conducting delivery checks and process evaluations.
Given their role in testing and experimentation, the size and thickness of dummy wafers are of paramount importance in ensuring accurate outcomes.

Wafers that undergo film deposition processes are referred to as film wafers, offering unique properties for specialized applications.
Film wafers incorporate various films, such as isolation films for layer separation, metal films for conductivity, and materials like resist and protective films for process enhancement.
