Title: P C Jann: Innovator in Optical Inspection Systems
Introduction
P C Jann is a notable inventor based in Santa Clara, CA (US). He has made significant contributions to the field of optical inspection systems, holding a total of 3 patents. His work focuses on enhancing the efficiency and accuracy of inspection processes in various applications.
Latest Patents
One of Jann's latest patents is an automatic high-speed optical inspection system. This innovative system utilizes at least one Time Delay Integration (TDI) sensor to image substrate portions of interest, ensuring they are illuminated with substantially uniform light. In one configuration, the system compares a substrate to prestored expected characteristic features. In another configuration, it inspects two patterns on a substrate by comparing them against each other. This process involves illuminating both patterns, imaging the first, and storing its characteristics in temporary memory before imaging the second pattern for comparison. The system continues this sequential comparison, noting agreements or discrepancies between the patterns. This technique is particularly useful for die-to-die inspections. A variation of this configuration employs two TDI sensors to simultaneously image both patterns, eliminating the need for temporary memory and streamlining the inspection process.
Career Highlights
Throughout his career, P C Jann has worked with various companies, including Kla Instruments Corporation. His expertise in optical inspection systems has positioned him as a key figure in the industry, contributing to advancements that improve inspection accuracy and efficiency.
