Title: Yiyu Zhang - Innovator in Specimen Alignment Technologies
Introduction
Yiyu Zhang is a notable inventor based in Santa Clara, CA, who has made significant contributions to the field of specimen alignment technologies. With a focus on improving inspection processes, Zhang's work has implications for various industries that rely on precise specimen handling.
Latest Patents
Yiyu Zhang holds a patent for the "Alignment of a specimen for inspection and other processes." This patent describes methods and systems for setting up the alignment of a specimen. The system includes computer subsystems configured to acquire two-dimensional (2D) images generated from the output of a detector at template locations on a specimen. The computer subsystems determine offsets in the x and y directions between these template locations using the 2D images. They also calculate the angle of the specimen concerning the output acquisition subsystem based on these offsets. If the angle exceeds a predetermined value, the system rotates the specimen and repeats the alignment steps. Conversely, if the angle is within the acceptable range, the system stores one of the 2D images for future alignment processes. The 2D images may include multi-mode images, which can be fused before determining the offsets. Zhang's innovative approach enhances the accuracy and efficiency of specimen alignment.
