  • Patent number: 11545623
    Abstract: Methods, systems, and devices for fabrication of memory cells are described. An electrode layer may have an initial thickness variation after being formed. The electrode layer may be smoothened prior to forming additional layers of a memory cell, thus decreasing the thickness variation. The subsequent layer fabricated may have a thickness variation that may be dependent on the thickness variation of the electrode layer. By decreasing the thickness variation of the electrode layer prior to forming the subsequent layer, the subsequent layer may also have a decreased thickness variation. The decreased thickness variation of the subsequent layer may impact the electrical behavior of memory cells formed from the subsequent layer. In some cases, the decreased thickness variation of the subsequent layer may allow for more predictable voltage thresholds for such memory cells, thus increasing the read windows for the memory cells.

  • Patent number: 9997606
    Abstract: A method is presented for forming a semiconductor structure. The method includes forming a bilayer buried insulator over a substrate, forming an extremely thin silicon-on-insulator (ETSOI) over the bilayer buried insulator, forming a dummy gate, and forming a source/drain next to the dummy gate, the source/drain defining a raised source/drain region. The method further includes depositing a dielectric material over the raised source/drain regions, removing the dummy gate to define a recess, implanting a species within a first layer of the bilayer buried insulator, and depositing a gate dielectric and a conducting material within the recess. The method further includes removing the substrate, etching the implanted portion of the first layer of the bilayer buried insulator to expose a surface of a second layer of the bilayer buried insulator, and forming a back gate over the exposed second layer, the back gate self-aligned to the ETSOI channel.

  • Patent number: 9941212
    Abstract: An advanced metal conductor structure and a method for constructing the structure are described. A pattern is provided in a dielectric layer. The pattern includes a set of features in the dielectric for a set of metal conductor structures. An adhesion promoting layer is created over the patterned dielectric. A ruthenium layer disposed over the adhesion promoting layer is deposited. A nitridation process is performed on the ruthenium layer to produce a nitridized ruthenium layer. Using a physical vapor deposition process, a cobalt layer is deposited disposed over the nitridized ruthenium layer. A thermal anneal is performed which reflows the cobalt layer to fill the set of features to form a set of metal conductor structures. In another aspect of the invention, an integrated circuit device is formed using the method.
