Paper Abstract

Multilayer x-ray reflectors which have layers that vary in thickness, either in depth or laterally along the surface, were prepared by sputtering. Alternating layers of W and C were deposited on flexible mica and smooth silicon-wafer substrates. X-ray diffraction properties of the multilayers were measured in the 1.54-8.34 A region. The mutlilayer on mica represents a dual-spacing depth-graded device. Diffraction from both the multilayer and mica was observed. A smoothly-depth-graded multilayer on silicon has a relatively-wide rocking curve which agrees well with diffraction theory. A laterally-graded multilayer on silicon has a bilayer thickness (d value) which varies linearly from 24.8 to 29.2 A in 6 cm.
