XwinSys is dedicated to the design, manufacturing, and marketing of novel metrology solutions for the semiconductor industry and other related industries. Its solutions are based on improved X-ray technology combined with an automated optical 3D scanner and 2D microscope. In 2019, XwinSys was acquired by Rigaku, a supplier of equipment for X-ray spectrometry, diffraction, and optics. XwinSys and Rigaku intend to use unique technologies from both companies to jointly develop new in-line X-ray metrology equipment for semiconductor front-end and back-end processes, MEMS, electronics devices and packaging, and other applications.
