Title: The Innovative Contributions of Robert G. Knollenberg
Introduction
Robert G. Knollenberg is a notable inventor based in Boulder, Colorado, recognized for his significant contributions to the field of particle detection and surface inspection technologies. With a total of 15 patents to his name, Knollenberg has developed innovative solutions that address critical challenges in various industries, particularly in semiconductor processing and glass manufacturing.
Latest Patents
Among his latest patents, Knollenberg has developed a surface defect inspection system and method. This system is designed to inspect objects, such as sheets of flat panel glass, for flaws or contamination at the surface. The inspection process utilizes 253.7 nm ultraviolet (UV) radiation to ensure that defects are detected only at the front surface. The scattered UV radiation from defects is collected by a UV dark field imaging system, which directs the information to a detecting unit, typically including a charge coupled device (CCD). This innovative system can detect defects as small as five microns within a ten-second sampling period.
Another significant invention is the nonintrusive modular particle detecting device. This device is particularly useful for microcontamination control in semiconductor processing environments. It features a viewing unit and a sensing unit as separate components. The viewing unit includes a detecting window and heated illuminating windows to prevent condensation. The sensing unit is designed to detect particles in fluid without physical intrusion, allowing for continuous operation and easy servicing.
