  • Patent number: 11758711
    Abstract: Described herein are embedded dynamic random-access memory (eDRAM) memory cells and arrays, as well as corresponding methods and devices. An exemplary eDRAM memory array implements a memory cell that uses a thin-film transistor (TFT) as a selector transistor. One source/drain (S/D) electrode of the TFT is coupled to a capacitor for storing a memory state of the cell, while the other S/D electrode is coupled to a bitline. The bitline may be a shallow bitline in that a thickness of the bitline may be smaller than a thickness of one or more metal interconnects provided in the same metal layer as the bitline but used for providing electrical connectivity for components outside of the memory array. Such a bitline may be formed in a separate process than said one or more metal interconnects. In an embodiment, the memory cells may be formed in a back end of line process.

  • Patent number: 11710765
    Abstract: A method for forming non-planar capacitors of desired dimensions is disclosed. The method is based on providing a three-dimensional structure of a first material over a substrate, enclosing the structure with a second material that is sufficiently etch-selective with respect to the first material, and then performing a wet etch to remove most of the first material but not the second material, thus forming a cavity within the second material. Shape and dimensions of the cavity are comparable to those desired for the final non-planar capacitor. At least one electrode of a capacitor may then be formed within the cavity. Using the etch selectivity of the first and second materials advantageously allows applying wet etch techniques for forming high aspect ratio openings in fabricating non-planar capacitors, which is easier and more reliable than relying on dry etch techniques.

  • Patent number: 11665915
    Abstract: According to principles as discussed herein, an EEPROM cell is provided and then, after testing the code, using the exact same architecture, transistors, memory cells, and layout, the EEPROM cell is converted to a read-only memory (“ROM”) cell. This conversion is done on the very same integrated circuit die using the same layout, design, and timing with only a single change in an upper level mask in the memory array. In one embodiment, the mask change is the via mask connecting metal 1 to poly. This allows the flexibility to store the programming code as non-volatile memory code, and then after it has been tested, at time selected by the customer, some or all of that code from a code that can be written to a read-only code that is stored in a ROM cell that is composed the same transistors and having the same layout.
