    Abstract: The process provides for obtaining in the areas intended for the formation of the transistors windows (9, 20, 10) in the intermediate oxide layer (5) between the two silicon layers (4, 11) and, before final etching of the two silicon layers (4, 11) and the intermediate oxide (5), application of a mask formed in such a manner as to superimpose on the second silicon layer (11) in the transistor areas coverings (13, 26, 14) wider than the corresponding windows (9, 20, 10) of the
    intermediate oxide layer (5).

    Abstract: The method for ion implant programing NMOS read-only memories comprises the step of increasing the concentration of boron in the channel only proximate to the source junction of the NMOS devices of the memory which are to be programed 'off'. In this manner it is possible to increase the threshold voltage of these devices without reducing the breakdown voltage thereof, so as to obtain a reliable operation of the device or memory element even for very-large-scale-integration circuits, with a reduced thickness of oxide.
