Dummy wafers (also referred to as test wafers) are primarily utilized for experimentation and testing, distinct from standard production wafers.
Reclaimed wafers are predominantly employed as dummy wafers (test wafers), making them a sustainable choice for testing purposes.

In production devices, dummy wafers play a crucial role in enhancing safety during the initial production stages and are vital for delivery checks and process evaluations.
The dimensions and thickness of dummy wafers are critical factors, especially given their frequent use in experiments and tests.

Wafers undergoing film deposition are termed film wafers, providing enhanced properties for various applications.
Film examples include isolation films for layer separation, metal films for conductivity, and process materials such as resist and protective films, each enhancing wafer functionality.
