  • Publication number: 20130075802
    Abstract: A vertical interconnect architecture for a three-dimensional (3D) memory device suitable for low cost, high yield manufacturing is described. Conductive lines (e.g. word lines) for the 3D memory array, and contact pads for vertical connectors used for couple the array to decoding circuitry and the like, are formed as parts of the same patterned level of material. The same material layer can be used to form the contact pads and the conductive access lines by an etch process using a single mask. By forming the contact pads concurrently with the conductive lines, the patterned material of the contact pads can protect underlying circuit elements which could otherwise be damaged during patterning of the conductive lines.

  • Patent number: 8383512
    Abstract: A method provides electrical connections to a stack of contact levels of an interconnect region for a 3-D stacked IC device. Each contact level comprises conductive and insulation layers. A portion of any upper layer is removed to expose a first contact level and create contact openings for each contact level. A set of N masks is used to etch the contact openings up to and including 2N contact levels. Each mask is used to etch effectively half of the contact openings. When N is 3, a first mask etches one contact level, a second mask etches two contact levels, and a third mask etches four contact levels. A dielectric layer may be formed on the sidewalls of the contact openings. Electrical conductors may be formed through the contact openings with the dielectric layers electrically insulating the electrical conductors from the sidewalls.

  • Patent number: 8325530
    Abstract: A method of performing an operation on a flash memory cell device, used when a gate coupling ratio between a floating gate and a control gate of less than 0.4. A potential is required to be applied across the control gate. Electrons are either injected to the floating gate from the control gate or ejected from the floating gate to the control gate. The operation associated with the injection or the ejection is determined by the nature of a silicon channel provided in the device. Devices using a bulk-tied FinFET-like structure are particularly suited to this method. The method is also particularly suited for use on cells in a NAND array.

  • Publication number: 20120267689
    Abstract: An integrated circuit memory device, including a memory circuit and a peripheral circuit, is described which is suitable for low cost manufacturing. The memory circuit and peripheral circuit for the device are implemented in different layers of a stacked structure. The memory circuit layer and the peripheral circuit layer include complementary interconnect surfaces, which upon mating together establish the electrical interconnection between the memory circuit and the peripheral circuit. The memory circuit layer and the peripheral circuit layer can be formed separately using different processes on different substrates in different fabrication lines. This enables the use of independent fabrication process technologies, one arranged for the memory array, and another arranged for the supporting peripheral circuit. The separate circuitry can then be stacked and bonded together.
