Title: Innovations of Liang-Guo Wang
Introduction
Liang-Guo Wang is a notable inventor based in Milpitas, CA, with a significant contribution to the field of substrate analysis and thin film technology. He holds a total of 10 patents, showcasing his innovative approach to solving complex problems in material science.
Latest Patents
One of his latest patents is titled "Patterned substrate surface mapping." This method involves measuring a characteristic of a substrate by directing an incident beam at an inspection grid of points on the substrate. The reflected beam is received with a position-sensitive detector, and the displacement of the reflected beam from its expected location is measured. A database of these displacement measurements is compiled, and the database is examined for effects of a pattern-induced anomaly. This process allows for the correction of pattern-induced errors in displacement measurements, thus overcoming issues with interpreting reflection angles in substrate stress analysis equipment.
Another significant patent is related to "Methods and systems for preparing a sample for thin film analysis." This system includes an energy beam source that generates an energy beam, which is directed to a sample. The energy beam is modified to have a substantially flat-top profile, allowing it to remove a portion of a contaminant layer on the sample and expose an analysis area of a thin film. This innovative method enhances the accuracy of thin film analysis.
