The Bullet is a portable device that accurately reads and scribes the majority of semiconductor wafer ID codes made today. The system performs at a very high throughput. It delivers technologically advanced features such as high quality illumination for all mark scribes including hard, soft, and “super soft.”
With a simple electronic interface made for selecting light type and adjusting light intensity—all in an extremely small OCR read head.
The tool offers a robust illumination system with ten light modes at 16 intensities each, and a patented telecentric on-axis narrow angle dark field lighting configuration that solves soft mark illumination problems.
ESI’s Bullet is a complete solution which easily integrates into existing OEM platforms.
Higher throughput and process tracking is available for machines such as wafer sorters, wafer probers, optical inspection tools, cluster tools and other processing tools that require automatic wafer identification.
