X terminal
a graphics workstation or specialized graphics terminal that runs an X Window System manager, such as the Motif Window Manager, as its only active process. An application running on another computer communicates with the X terminal according to X Window System protocol.

X Windows
a suite of specifications for standardized graphics programming; the software technology that supports the windowing environment on most workstation-class computers It is based on X11, originally developed by the Massachusetts Institute of Technology (MIT) and Digital Equipment Corporation.
X windows
Commercial operating software that overlays the operating system of computers and allows workstation users to manage multiple processes with a graphical interface. Window managers, such as Motif and OpenLook, provide the specific user interface to X.

X-ray fluorescence
1: the property of atoms to absorb X rays and emit light of characteristic wavelengths. 2: a material diagnostic technique that determines the surface concentration of contaminants.

X-ray stepper
A rule of thumb is that one must use a wavelength of light that is smaller than the size of the feature one is trying to create in a photo process. People have thought for years that the industry would have to abandon light and move to x-rays for patterning circuits as circuit dimensions inexorably shrank. The stepper manufacturers, however, kept applying their ingenuity, finding ways to use shorter wavelengths of light. At the 0.25 and 0.18 micron levels, excimer lasers working in the deep ultraviolet range of light are adequate, but there is a chance that x-ray steppers will finally have their day when semiconductor manufacturing moves below the 0.18 micron range (probably not for a few more years).
X-X axis
the horizontal axis, or axis in the left-to-right direction, in a plane Cartesian coordinate system along which a row of functional patterns is nominally disposed by stepping and repeating.

Xylene
any one of a family of poisonous, flammable, and colorless hydrocarbon liquids derived from coal tar, wood tar, and petroleum. These liquids are isomeric (contain the same chemical components, but have differing physical and chemical properties because of the arrangement of the molecules).
