Silicon wafers

Silicon wafers

Silicon wafers are cut from Silicon single crystal using internal diameter diamond discs. They are used for production of silicon substrates and membranes.
The below mentioned parameters are dealing with our standard products.
On the customer's request we are ready to discuss orders for wafers with some other parameters.
