Used AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4280A #9001567 for sale

AGILENT / HP / HEWLETT-PACKARD / KEYSIGHT 4280A is a Wafer Testing and Metrology equipment designed for semiconductor production and quality assurance. It is comprised of two separate components: a robotic wafer handler and a multi-sensor metrology station. The wafer handler is capable of high-speed automation, allowing it to transport wafers quickly and accurately from the cassette load station to the metrology station. The metrology station is equipped with a suite of measurement sensors: a laser interferometer, focusing optics, and a deflectometer imaging system for scanning and imaging the wafer surface. Using these sensors, high-resolution testing and metrology of the wafer is possible, covering a range of parameters such as surface morphology, electrical properties, and layer thickness. HP 4280A can analyze wafers with dimensions up to 200 millimeters, while at the same time providing an exceptional level of accuracy and repeatability. It also features an advanced thermal control unit, providing a stable temperature environment capable of maintaining a temperature range as narrow as ±0.001°C. This ensures that readings taken during testing and metrology will remain consistent even during rugged operation. The machine also employs advanced software tools for quality control and data analysis, allowing for the automation of highly complex test and metrology processes. AGILENT 4280A is designed to be a versatile and reliable wafer testing and metrology station, capable of quickly producing and measuring results with an exceptionally high degree of accuracy and repeatability. Its unique combination of features and high level of performance makes it an ideal choice for production and quality assurance in the semiconductor industry.
