Dummy wafers, also known as test wafers, are primarily designed for experimental and testing purposes, distinguishing them from conventional production wafers.
As such, reclaimed wafers are predominantly utilized as dummy wafers (test wafers).

Dummy wafers are extensively used in production devices to enhance safety at the initial production stages and are vital for delivery checks and process form evaluations.
Given their frequent use in experiments and testing, the size and thickness of dummy wafers are critical factors in most circumstances.

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

Company Profile

Fine Silicon Manufacturing(shanghai) Ltd.(FSM )was established in 2008 and is headquartered in Shanghai's which located in Waigaoqiao Free Trade Zone.
FSM is one of the earliest enterprises engaged in silicon wafer processing and sales in China.
In 2015, the Japanese branch KOD Corporation was established in Tokyo.
At present, FSM Group has two plants in Shanghai and Japan, with a monthly processing capacity of 100,000pcs 12inch silicon wafers.
At the sales end, FSM, KOD and upstream domestic and oversea wafer makers, wafer reclaim house and downstream semiconductor foundary have stable and good cooperation, customers all over the domestic and foreign countries and regions.
The main business also expanded from single Dummy wafer to the agent of reclaim wafer house, providing wafer reclaim business from 6 -12 inch;
At the same time, we also provide Test and Dummy wafers of various sizes from the wafer maker. 
FSM also provides customized coatings wafer in various sizes and film thickness, eg: Thermal oxide, PETEOS, LP-Nitride, PE SiN etc.
In the field of third-generation semiconductors, we are also active and currently offer various sizes of SiC, lithium tantalate/lithium niobate (LiTaO3 (LT) and LiNbO3 (LN)), glass wafers, etc.
