Abstract
We have developed three new gate tracking functions to acquire dead-pixel-free and fine inspection images for advanced LSI packages with rough surface using a scanning acoustic tomo-graph. These are predicted surface gate tracking, double surface gate tracking and predicted S2-gate tracking methods. The advantages of these functions are demonstrated by using various test samples.
