  • Method of fabricating a read only memory in MOS technology, and memory thus obtained
    Patent number: 5679594
    Abstract: A method of fabricating a read only memory consisting of a matrix of arrays of enhancement-mode or depletion-mode programmed MOS transistors that consists, on a silicon substrate (SU) of a first conduction type, in defining by masking, retrograde wells of the same conduction type as that of the substrate, and then retrograde wells of conduction type opposite to that of the substrate. Removal of the protective oxide allows thus to predefine the enhancement-mode and depletion-mode transistors.
