  • Publication number: 20230178479
    Abstract: A method is presented for manufacturing an insulated conductive via. The via crosses a first stack of layers to reach a first layer. A first cavity is formed partially extending into the first stack of layers. A second stack of layers is formed over the first stack of layers and in the first cavity. The second stack of layers includes an etch stop layer and an insulating layer. A second cavity is then formed extending completely through first and second stacks of layers to reach the first layer. An insulating liner then covers the walls and bottom of the second cavity. The insulating liner is then anisotropically etched, and the second cavity is filled by a conductive material forming the core of the via.

  • Publication number: 20230109590
    Abstract: A phase change filter is formed by an arrangement of dots, wherein each dot is made of a phase change material. A heating layer of electrically conductive material extends under the arrangement of dots. Current passing through the heating layer changes the dots between two states to alter attenuation of light passing through the filter.

  • Publication number: 20220005850
    Abstract: An optoelectronic device includes a photodiode. At least a portion of an active area of the photodiode is separated from a neighboring photodiode by a first wall including a conductive core and an insulating sheath and by a second optical insulation wall. The first wall and second optical insulation wall further extend parallel to each other and separate the active area from a memory area of the photodiode.

  • Patent number: 11189792
    Abstract: A resistive non-volatile memory cell includes a first electrode, a second electrode and an oxide layer disposed between the first electrode and the second electrode, the memory cell being capable of reversibly switching between: —a high resistance state obtained by applying a first bias voltage between the first electrode and the second electrode; and—a low resistance state obtained by applying a second bias voltage between the first electrode and the second electrode; the oxide layer including a switching zone forming a conduction path prioritised for the current passing through the memory cell when the memory cell is in the low resistance state. The oxide layer includes a first zone doped with aluminium or silicon, the aluminium or silicon being present in the first zone with an atomic concentration that is selected so as to locate the switching zone outside the first zone.

  • Patent number: 10446564
    Abstract: The invention relates to a non-volatile memory that comprises selection transistors. Each selection transistor includes a layer of semiconductor material with a channel region and conduction electrodes, a gate stack including a gate electrode and a gate insulator, an isolation trench between the transistors, a storage structure of the RRAM type comprising a control electrode, and a dielectric layer formed under the control electrode and in the same material as the gate insulator, comprising a central part directly above the isolation trench and ends extending directly above conduction electrodes, and configured so as to form conducting filaments. The said storage structure and the said selection transistors are formed in the same pre-metallization layer.
