Used LAM RESEARCH Rainbow 4420 #9300194 for sale

LAM RESEARCH Rainbow 4420 is an advanced etching and ashing tool used in the fabrication of high-Tech electronic devices. This tool applies a thin layer of material, such as an insulating layer, to create a patterned mask or other structure. Rainbow 4420 etch and asher offers high-accuracy etch and ashing for ultra-thin layers with excellent repeatability and uniformity. LAM RESEARCH Rainbow 4420 is equipped with a state-of-the-art source chamber, which contains rigid baffles and vacuum pumps that provide an extremely clean, particle-free environment. To ensure high throughput and low-cost operation, the system is equipped with an integrated resistance heater for rapid thermal treatment. Rainbow 4420 also contains a gas cabinet, which has a mixture of argon, oxygen, and nitrogen, as well as other possible gases. This gas cabinet is fully automated and provides perfect control of etching conditions. LAM RESEARCH Rainbow 4420 operates in two modes, sequential etch and asher, or concurrent etch and asher. In sequential mode, the wafers are loaded into the system and the first etch is performed followed by the ash. In concurrent mode, the wafers are exposed to etching and ashing at the same time. This mode is ideal for applications such as inter-layer isolation, selectivity, doping, and protective layers. Rainbow 4420 includes a user-friendly graphical user interface (GUI) for easy programming and monitoring. The GUI shows all the relevant parameters, and operators can adjust them as needed in order to optimize their results and improve process reproducibility. LAM RESEARCH Rainbow 4420 etch and asher also offers combined temperature and pressure control, allowing for precise and accurate etching and ashing. Rainbow 4420 is an ideal etch and ashing tool for many types of semiconductor and electronic devices, offering a wide range of advantages, including excellent repeatability, uniformity, and low cost of operation. Whether used in sequential mode or concurrent mode, LAM RESEARCH Rainbow 4420 tool is an excellent choice for achieving exceptional results in etching and ashing.
