  • Patent number: 10651286
    Abstract: A silicon nitride cap on a gate stack is removed by etching with a fluorohydrocarbon-containing plasma subsequent to formation of source/drain regions without causing unacceptable damage to the gate stack or source/drain regions. A fluorohydrocarbon-containing polymer protection layer is selectively deposited on the regions that are not to be etched during the removal of the nitride cap. The ability to remove the silicon nitride material using gas chemistry, causing formation of a volatile etch product and protection layer, enables reduction of the ion energy to the etching threshold.

  • Patent number: 10164007
    Abstract: A semiconductor structure and a method for fabricating the same. The semiconductor structure includes a gate stack disposed on a substrate. A gate contact is disposed in contact with an end portion of the gate stack. An air gap spacer is disposed in contact with a portion of the gate stack. The end portion of the gate stack is absent the air gap spacer. The method includes forming a gate contact in contact with a gate stack. A spacer surrounding at least a portion of the gate stack is removed after the gate contact has been formed. The removal of the spacer forms a trench surrounding the gate stack and stopping at the gate contact. An air gap spacer is formed within the trench.

  • Patent number: 10147784
    Abstract: A microelectronic device contains a high voltage component having a high voltage node and a low voltage node. The high voltage node is isolated from the low voltage node by a main dielectric between the high voltage node and low voltage elements at a surface of the substrate of the microelectronic device. A lower-bandgap dielectric layer is disposed between the high voltage node and the main dielectric. The lower-bandgap dielectric layer contains at least one sub-layer with a bandgap energy less than a bandgap energy of the main dielectric. The lower-bandgap dielectric layer extends beyond the high voltage node continuously around the high voltage node. The lower-bandgap dielectric layer has an isolation break surrounding the high voltage node at a distance of at least twice the thickness of the lower-bandgap dielectric layer from the high voltage node.

  • Patent number: 10121965
    Abstract: An alternating stack of insulating layers and electrically conductive layers is formed over a substrate. Sidewalls of the electrically conductive layers are laterally recessed to form laterally recessed regions. After formation of a conformal barrier material layer in the laterally recessed regions and on the sidewalls of the insulating layers, an amorphous precursor memory material layer is deposited in lateral cavities and over the conformal barrier material layer. An anneal process is performed to selectively crystallize portions of the amorphous precursor memory material layer in the lateral cavities into crystalline memory material portions while not crystallizing portions of the amorphous precursor memory material outside the lateral cavities. Remaining amorphous portions of the amorphous precursor memory material layer are removed selective to the crystalline memory material portions. A vertical conductive line is formed on the crystalline memory material portions.
