“W-GM series” wafer edge grinding machines, that the improvement of its performance never stops, are used in production lines of all over the world.”

W-GM-4250The requirement for the wafer quality is getting higher and the condition of wafer edge is getting more important.

The edge grinders “W-GM series” process edge grinding of various kind of materials such as Silicon, sapphire and SiC.As a solution for that, Our W-GM series are highly rated among manufactures of silicon, compound materials and other wafer shaped materials.

Wafer edge grinding machine also draws the attention as a solution for the yield loss due to the knife edge of device wafer in the back end process.


In the semiconductor manufacturing process, from the wafer manufacturing to the device manufacturing, the quality improvement of wafer edge is necessary in recent years.We make proposals that achieve the improvement of quality, CoO and yield with our machine.
