Dummy wafers (also known as test wafers) are predominantly utilized for experimental and testing purposes, distinctly differing from conventional product wafers.
Reclaimed wafers are predominantly employed as dummy wafers (test wafers), offering a sustainable and efficient testing solution.

To enhance safety and efficiency in initial production stages, dummy wafers are essential. They play a crucial role in delivery checks and evaluating process forms.
Given their frequent use in experiments and tests, the size and thickness of dummy wafers are critical factors in most applications.

Wafers that undergo film deposition processes are referred to as film wafers, integral to various advanced applications.
Examples of films used include isolation films for layer separation, metal films as conductive materials, and process materials such as resists and protective films, ensuring optimal performance and protection.
