Used TEL / TOKYO ELECTRON Unity IIe 855DD #9294562 for sale

TEL / TOKYO ELECTRON Unity IIe 855DD is an etcher (also known as an asher) designed to efficiently etch semiconductor wafers. It is a highly intelligent, computer-controlled equipment, capable of reliably etching wafers on a mass scale. The system consists of two stainless steel cassettes, a control unit, and a scanning electron microscope, all controlled by a single operating platform. TEL UNITY IIE 855 DD features a chemical etch unit, enabling precise amounts of etchants to be applied to the processed wafer. This machine is driven by a highly accurate threading technology, which transfers the wafer from cassette to cassette and ensures minimal misalignment. The tool also features a heated nozzle oven, which gently heats the etchant as it is dispensed, resulting in more consistent etch results. The scanning electron microscope offers a high resolution, three-dimensional image view for both etch and post-etch process monitoring. This image can be used to monitor the progress of the etch, identify process anomalies, and record wafer data. Additionally, the asset offers a range of built-in statistical process control capabilities, allowing the user to review model data in order to optimize etching processes. TOKYO ELECTRON UNITY II E-855DD is powered by a Windows-based operating platform, allowing for quick and simple user-interface customization, as well as simplified data transfer and analysis. The equipment features both automatic and manual processes, and comes with a range of built-in diagnostic and maintenance tools, allowing users to quickly and easily maintain their equipment and prevent downtime. Overall, UNITY II E-855DD is an advanced and reliable etcher, providing reliable and repeatable etch results on a mass scale. Its comprehensive feature set, reliable performance, and simple operation makes it an ideal solution for a wide range of etching applications.
