X-ray lithography is a process used in semiconductor device fabrication industry to selectively remove parts of a thin film of photoresist. It uses X-rays to transfer a geometric pattern from a mask to a light-sensitive chemical photoresist , or simply "resist," on the substrate to reach extremely small topological size of a feature.

With the advancement of image processing software the number applications for automated x-ray inspection is huge and constantly growing. The first applications started off in industries where the safety aspect of components demanded a careful inspection of each part produced (e.g. welding seams for metal parts in nuclear power stations) because the technology was expectedly very expensive in ...
A typical fab will have several hundred equipment items. Semiconductor fabrication requires many expensive devices. Estimates put the cost of building a new fab at over one billion U.S. dollars with values as high as $3–4 billion not being uncommon. For example, TSMC invested $9.3 billion in its Fab15 in Taiwan.

An X-ray generator generally contains an X-ray tube to produce the X-rays. Possibly, radioisotopes can also be used to generate X-rays. [1]An X-ray tube is a simple vacuum tube that contains a cathode, which directs a stream of electrons into a vacuum, and an anode, which collects the electrons and is made of tungsten to evacuate the heat generated by the collision.
Advanced X-ray Imaging Satellite (AXIS) is a space telescope under development by NASA for launch in 2032. [1] It is a NASA Probe mission concept designed for high angular resolution X-Ray imaging. [2] The mission goals are to examine galaxies over cosmic time, feedback in galaxies, Black Hole strong gravity, Dual AGN, the high redshift universe.
Advanced television is an array of features enabled by digital technology that significantly changes analog television.. The term "advanced television" was first used at the MIT Media Lab in the early 1990s to explain why high-definition television was only an early step in the foreseeable enhancements to the medium.
X-ray fluorescence (XRF) is the emission of characteristic "secondary" (or fluorescent) X-rays from a material that has been excited by being bombarded with high-energy X-rays or gamma rays.
