909,158. Charge storage electrodes. RADIO CORPORATION OF AMERICA. March 9, 1959 [March 17, 1958], No. 8129/59. Class 39 (1). A storage electrode is made by forming an insulating oxide film 12 on a sheet of a first metal 10, forming a substantially uniformly apertured protective coating 14 over the film 12, dissolving away portions of the oxide film which are exposed by the apertures 16 to uncover corresponding portions of the sheet 10, filling in these dissolved-away portions with a second metal 20 and removing the sheet 10. The protective coating 14 may also be removed. The first metal may be titanium manganese zirconium or aluminium and the second, copper silver, iron, gold or nickel. The coating 14 may be formed by using a photo-sensitive resist or by depositing a metallic sulphide through a wire grill. |
