Latest Patents

Siddons holds a patent titled "Method and apparatus for micromachining using hard X-rays." This patent describes a method that utilizes an X-ray source, such as a synchrotron, to expose thick photoresist. The process ensures that the photoresist at the exit surface receives a sufficient threshold dose for development, while the entrance surface is protected from excessive exposure. The X-ray beam is carefully shaped to eliminate lower energy photons, allowing higher energy photons to effectively reach the photoresist target. This technique enables machining of photoresists like polymethylmethacrylate to micron tolerances and allows for the creation of complex three-dimensional structures.
