Used PSK TERA 21 #9250689 for sale

PSK TERA 21 is an etcher/asher designed for high-accuracy etching and trimming of semiconductor wafers. It features a state-of-the-art etching and erasing equipment capable of providing up to a 20 μm processing resolution. The system is built on a strong frame with advanced X-Y axis devices and a precision-controlled electroplating unit. The machine is equipped with an automated control unit with built-in measurement, inspection, and adjustment functions. This enables the user to quickly and accurately adjust the parameters of the etching and erasing processes. TERA 21's etching and erasing unit contains 4 high speed etching heads, each with a very fine resolution of 0.2 μm per step. The machine is capable of changing output, pressure, temperature and frequency in a matter of seconds. The etching unit features an adjustable pressure range of 0.5 to 2.2 parsecs, with temperature ranges from 0°C to 40°C. It is also equipped with 6 different etching and erasing actuators that can be set for times from 0.2 to 5.0 seconds. This etcher/asher is designed to achieve precise etching results without destroying the wafer's structure. Its unique design ensures that the etching process is fast, efficient, and highly uniform. Additionally, this tool is capable of multi-directional etching, which allows for etching with greater efficiency and accuracy.
