Dummy wafers, also known as test wafers, are primarily utilized for experimental and testing purposes, differing from standard production wafers.
Reclaimed wafers find their primary application as dummy wafers (test wafers), meeting specific testing needs.

In production, dummy wafers enhance safety at the start of the manufacturing process and are crucial for delivery verification and process evaluation.
Given their experimental and testing roles, the size and thickness of dummy wafers are critical considerations in most scenarios.

Wafers enhanced by film deposition are termed film wafers.
Film examples used in growth include isolation films for layer separation, metal films for conductivity, and process materials like resist and protective films.
