概要（Overview）

The EJD-9BL is a double-sided polishing machine that belongs to the EJD series. It supports a wide range of lapping and CMP processing of conventional abrasives, diamond abrasive, and fixed abrasive plates. The standard full safety cover makes it suitable for use in a semiconductor manufacturing environment. Additionally, it comes with a variety of optional functions such as real-time part thickness detection, actual pressure monitor and control, and low-pressure, low-speed descent control of the upper surface lapping platen. These features are essential for simultaneous double-sided polishing of thin wafers.
