    摘要: Two process flows are disclosed for the stacked etch fabrication of an EPROM array that utilizes cross-point cells with internal access transistors. In each process flow, the edges of the polysilicon 1 floating gates parallel to the polysilicon 2 word line are self-aligned to the word line, eliminating parasitic polysilicon 2 transistors and process requirements for coping with such transistors.

    摘要: A contactless EPROM cell array in accordance with the present invention comprises an N+ source line formed in the silicon substrate. First and second N+ drain lines are formed in parallel with and spaced-apart from the source line on opposite sides of the source line. First and second field oxide strips are formed in parallel with but spaced-apart from the first and second drain lines, respectively, such that the source line/drain line structure is bounded on both sides by the first and second field oxide strips to separate this structure from adjacent similar source/drain line structures. First and second polysilicon 1 lines overlie the channel regions between the first drain line and the source line and the second drain line and the source line, respectively, and are separated therefrom by a first layer of dielectric material. A plurality of spaced-apart, parallel polysilicon 2 word lines overlie and run perpendicular to the first and second polysilicon 1 lines and are spaced-apart therefrom by a second dielectric material. Thus, the EPROM cells of the array are defined at each crossing of the polysilicon 1 lines and the polysilicon 2 word lines.
