1. A method of manufacturing an x-ray window, the method comprising:
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 boron, forming an upper-boron-film on the top-side of the wafer with a near-side of the upper-boron-film facing the top-side of the wafer and a top-surface opposite of the near-side, and forming a lower-boron-film on the bottom-side of the wafer;
etching through a center of the lower-boron-film to form an annular-film encircling an aperture, the annular-film having a near-side facing the wafer and a far-side opposite of the near-side; and
etching through a center of the wafer at the bottom-side to form a support-frame encircling an aperture.
