BUSINESS
Processing client's used silicon wafers and reclaim them and make it reusable. We are capable of reclaiming used silicon wafers equivalent to brand new silicon wafers with our technology.
We are one of the pioneers of the silicon wafer reclaiming since 1972. From the begining , All employees make an effort to enhance quality,technology and customer satisfaction. Our high quality services and products are produced under the state of the art reclaiming and equipment in Nagasaki.
Main material of silicon wafers is silicon which produced from a mineral called silica stone. Especially, silicon that is used for silicon wafers must be high-purity polycrystalline.
In order to preserve limited resources, we care about global environment by doing our business.
What we do is processing client's used silicon wafers and reclaim them and make them reusable. The quality of processing is equivalent to virgin silicon wafers. In the condition of wafers that are unable to reclaim, we will purchase your unrecyclable wafers.
Silicon wafers which used for examination are insulating film or metal film are deposited. We are capable of removing film with chemical liquid depending on each film at our facility.
Checking all silicon wafers condition after silicon wafers film removal. Before polishing, we inspect thickness and other characteristics.
At polishing process, we are capable of adjust polishing in micron units. removing scratches and particles from the surface of the silicon wafers.
By doing this process, we make it possible to reclaim silicon wafers high standard.
After being polished, silicon wafers will be cleaned and particles and metallic impurity are removed.
All silicon wafers will be visual inspected. After that, Conducting measuring by particle counter.
