High-precision sensor technology at Touch Taiwan
Summary
An extension of the industry-leading WaferSense Airborne Particle Sensor (APS) technology that is documented by fabs as the Best-Known Method (BKM), the IPS quickly identifies, monitors and enables troubleshooting of particles down to 0.1µm. They can compare past and present data, as well as one tool to another, and see the effects of cleaning, adjustments and repairs in real-time. The desire for a contamination-free process environment, coupled with stringent manufacturing requirements are driving the need for a best-in-class process to detect particles in gas and vacuum lines,” said Dr Subodh Kulkarni, President and CEO, CyberOptics, “The IPS can quickly identify when and where particles originate, as well as the source, saving significant time and expense while maximizing yields and tool uptimes.” The company will also display the NanoResolution MRS sensor that is integrated into CyberOptics’ WX3000 system for wafer-level and advanced packaging inspection and metrology. While retaining its ability to reject spurious multiple reflections, it adds the ability to capture and analyze specular reflections from shiny surfaces of solder balls, bumps and pillars, providing highly accurate inspection and metrology. With data processing speeds in excess of 75 million 3D points per second, the WX3000 system delivers production-worthy throughput greater than 25 wafers (300mm) per hour.
