Abstract: A process for forming an integrated circuit calls for the provision of at least one matrix of non-volatile memory cells including an intermediate dielectric multilayer comprising a lower silicon oxide layer, an intermediate silicon nitride layer and an upper silicon oxide layer. The process calls for the simultaneous provision in zones peripheral to the memory cells of at least one first and one second transistor type each having a gate dielectric of a first and a second thickness respectively. After formation of the floating gate of the cells with a gate oxide layer and a polycrystalline silicon layer and the formation of the lower silicon oxide layer and of the intermediate silicon nitride layer, the process in accordance with the present invention includes removal of said layers from the zones peripheral to the matrix, and formation of a first silicon oxide layer over the substrate in the areas of both types of transistor.

Abstract: A process of fabricating a floating-gate memory device, the process including the steps of: forming a stack of superimposed layers including a floating gate region, a dielectric region, and a control gate region; and forming an insulating layer of oxynitride to the side of the floating gate region to completely seal the floating gate region outwards and improve the retention characteristics of the memory device. The insulating layer is formed during reoxidation of the sides of the floating gate region, after self-align etching the stack of layers and implanting the source/drain of the cell.

Abstract: A process for forming an integrated circuit includes at least one matrix of non-volatile memory cells having an intermediate dielectric multilayer including at least a lower dielectric material layer and an upper silicon oxide layer. The integrated circuit includes at least one transistor simultaneously formed in zones peripheral to the matrix and having a gate dielectric of a first thickness. After formation of the floating gate with a gate oxide layer and a polycrystalline silicon layer and the formation of the lower dielectric material layer, the process includes removal of said layers from the peripheral zones of the matrix; deposition of said upper silicon oxide layer over the memory cells, and over the substrate in the areas of the peripheral transistors; and formation of a first silicon oxide layer at least in the areas of the peripheral transistors. A second transistor type can be formed having a gate dielectric of a second thickness, thinner than said first thickness, in successive steps.

Abstract: The method described provides for the formation of thin thermal oxide on areas of a silicon die intended for memory cells and other components of the peripheral circuits of the memory. To improve the quality of the oxide of the cells essentially in terms of resistance to degradation due to the passage of charges through it during the operation of the memory, the method provides for a step for the high-temperature nitriding of the oxide. According to a variant, the nitrided oxide formed on the areas intended for the components of the peripheral circuits is removed and then formed again by a similar thermal oxidation treatment followed by high-temperature nitriding.

Abstract: The use of an O--N--RTN (Oxide-Nitride-Rapid Thermal Nitrided Polysilicon) interpoly dielectric multilayer instead of a customary O--N--O (Oxide-Nitride-Oxide) multilayer in the floating gate structure of a progammable, read-only memory cell has beneficial effects on the performance of the cell and facilitates its scaling.
