Abstract

In this batch fabrication method of making memory arrays, two orthogonally arranged sets of parallel wires 1 1 and 13 are formed into a grid. One crossover of the platinum wires is shown. The grid is immersed in a mixture of ferrite and a decomposable organic material, e. g., polyvinyl acetate in solvent. The mixture is such that it adheres to the wires. Current I is passed through the grid or wires as indicated by the arrows. The adhered mixture assumes the outline as shown. With the currents still applied, the wire grid with adhered mixture is then heat treated for pyrolysis. The result is an array having sintered ferrite cores with the adherence outline at the crossovers of wires of the grid.
