ABSTRACT:
A method of making a grid for a cathode-ray tube includes the process of etching an electrically conductive base member of a first material from two sides through related openings in electrically conductive layers of a second material which overlays the two sides of the base material. Etching continues until an aperture of sufficient size is formed that the overlying layers overhang the aperture in the base member.
