概要（Overview）

The Oxford Plasmalab 133 is a system used for plasma etching through a process called Reactive Ion Etching (RIE). This refurbished system is designed for GaN etching and has a platen that measures 330mm. It has an RF power of 600W at a frequency of 13.56MHz and features a water-cooled electrode that can operate within a temperature range of 10°C to 80°C. The system also includes a load lock with a turbo pump and an end-point detection system that utilizes Verity Optical emission spectroscopy within the range of 200-800nm. The gas pod of the system has six lines, including mass flow controllers for gases such as Ar, CL, BCL3, and N2O.
