Used LAM RESEARCH 4428 #9130367 for sale

LAM RESEARCH 4428 etcher/asher equipment is a single-chamber plasma activation process tool designed for developing and fabricating next-generation semiconductor chips. 4428 etcher/asher system uses an advanced chemical process to create precise and perfect etched shapes in a wide range of materials, including polyimide, polysilicon, and nitride layers. The etched shapes can range from simple masks and contact layers to more complicated features such as trenches, slots, and stepped features. LAM RESEARCH 4428 etcher/asher unit also supplies a direct plasma-etching process to improve the depth of the etched structures. 4428 measures just over four feet wide, four feet in depth, and three feet high and contains a C300 Plus controller operating machine with a built-in LCD monitor. The unit offers the flexibility of both a batch and a single-wafer processes through its self-contained tool. The mixing chamber features a quartz showerhead that offers quick, repeatable uniformity. LAM RESEARCH 4428 is ideal for creating precise process control as it is compatible with popular photolithography processes. 4428 has a number of built-in process gases to maximize the etching results, such as chlorine, argon, and nitrogen, and a vacuum control asset to control the pressure and mix the right amount of process gases. LAM RESEARCH 4428 also offers a selection of engineering configurations and chamber materials, along with the ability to store process recipes, enabling the user to repeat recipes and produce high-quality parts reliably. 4428 also features an on-screen password access control that provides added security, and allows the user to view process parameters, monitor gas flow, and control pressure levels from a central touchscreen interface. The intuitive interface allows for accurate and easy operation, along with full data logging capabilities for detailed tracking and error reporting. Overall, LAM RESEARCH 4428 etching / asher is a highly reliable and user friendly model for a wide range of etching needs. With its advanced processing capabilities, accurate and repeatable results, and easy operation, 4428 is the perfect equipment for semiconductor manufacturers looking for superior control and repeatable results.
