Title: Paul Anthony Ryan: Innovator in X-ray Measurement Technologies

Introduction

Paul Anthony Ryan is a distinguished inventor based in Darlington, GB, known for his significant contributions to the field of X-ray measurement technologies. With a total of five patents to his name, Ryan has developed innovative methods and apparatuses that enhance the precision and efficiency of X-ray characterization.

Latest Patents

One of Ryan's latest patents is focused on the "Transmission X-ray critical dimension (T-XCD) characterization of shift and tilt of stacks of high-aspect-ratio (HAR) structures." This method involves generating and directing an X-ray beam to a sample comprising at least two layers stacked on one another. The X-ray beam is incident on a sample location where the layers contain respective high aspect ratio structures. By measuring the X-ray scatter profiles emitted from the sample as a function of tilt angle, Ryan's method estimates the shift between the layers and their characteristic tilt.

Another notable patent is for an apparatus that utilizes multiple sources and detectors for high-throughput X-ray topography measurement. This apparatus includes a source assembly that directs multiple X-ray beams to irradiate overlapping regions on a sample. The detector assembly captures the diffracted X-ray beams and produces electrical signals in response. The scanning assembly moves the sample relative to the source and detector assemblies, while the processor identifies defects in the sample by processing the electrical signals.
