HIGH-INFORMATION-DENSITY STORAGE SURFACES.
Abstract
This program is devoted to the preparation and investigation of two novel kinds of electron-beam-addressable storage elements of submicron size and densely packed arrays of these elements; also to the construction of a large-capacity, high-speed, electron-beam-addressable, data-storage system utilizing regular arrays of these elements. Work on storage mosaics was devoted to further development of techniques for the preparation of regular arrays of densely packed micro-cap elements including: investigations of other resists besides tetrakistriphenyl siloxytitanium, such as KPR, Shipley's AZ 111, and poly(methyl metharcrylate); argon-ion sputtering of molybdenum films; and lead-fluoride etching of aluminum-oxide films. Appropriate combinations of these techniques appear promising. The development of a computer program for the design of electron-optical systems capable of scanning 100,000,000 elements per field for mosaic fabrication and for element address is continuing. Concurrently, the present molybdenum-lens electron-optical system is being reassembled to include a velocity-selector/electron-multiplier readout unit and a bakeout heater. (Author)
