Used RITEC RAM 1000 #293609564 for sale

RITEC RAM 1000 is a wafer testing and metrology equipment that accurately and reliably measures a variety of wafer characteristics such as resistivity, wafer thickness, dopant concentration, and defects. It is equipped with a proprietary optical design that combines illumination and imaging, allowing for the acquisition of highly precise 3D information. The system utilizes a coherent light source and advanced optics to measure the physical and optical properties of the wafer. by reflecting the coherent light off the wafer surface to acquire an interference pattern. The interference pattern is analyzed to find the angle-dependent amplitude for 2D images and height-dependent amplitude for 3D images. The unit also utilizes a Pixel Accumulator to accurately measure the absolute surface profile of the wafer with fast and high resolution. RAM 1000 is designed with several key features, such as a large sample area (up to 400mm wafer size) and a high-speed scanner that eliminates the need for mechanical scanning stage. This allows it to quickly and accurately measure wafer properties without the need for mechanical scanning. The machine is also equipped with a variety of image analysis and height measurement functions, allowing for fast and accurate detection of defects. The tool also offers a multitude of advanced analysis and automated process control functions, allowing for rapid and efficient production of high-performance wafers. This includes automatic 2D image analysis, 3D conformal mapping, and advanced scanning techniques such as wafer pattern recognition, resistivity measurement, chemicals mapping, and wet etch depth measurement. RITEC RAM 1000 is an excellent choice for high-volume production and quality control applications, providing reliable and accurate measurements for a variety of wafer characteristics. This makes it ideal for semiconductor manufacturers and wafer testing facilities that require fast and reliable wafer measurements. The asset is also easy to use and maintain, ensuring minimal downtime and maximum productivity.
