Claim 12:
13. A method of manufacturing an x-ray window, the method comprising the following steps in the following order:
placing a wafer in an oven, the wafer having a top-side and a bottom-side, the top-side and the bottom-side opposite of each other and parallel with respect to each other;
introducing a gas into the oven, the gas including diborane, forming an upper-boron-film on the top-side of the wafer, the upper-boron-film having a near-side and a far-side opposite of each other, the near-side of the upper-boron-film facing the top-side of the wafer, the upper-boron-film having ≥97 weight percent boron and ≥0.3 weight percent hydrogen;
etching through a center of the wafer at the bottom-side to form a support-frame encircling an aperture, the near-side and the far-side of the upper-boron-film facing atmospheric pressure, a gas, or both; and
depositing an aluminum-film directly on the near-side of the upper-boron-film.
