  • Publication number: 20230395729
    Abstract: Disclosed herein are memory devices with gradient-doped control gate material, as well as related methods and devices. In some embodiments, a memory device may include a first isolation material, a second isolation material, and a control gate material between the first isolation material and the second isolation material along an axis. The control gate material may include a dopant having a non-uniform concentration along the axis.

  • Patent number: 11600468
    Abstract: Embodiments described herein relate to gas line systems with a multichannel splitter spool. In these embodiments, the gas line systems will include a first gas line that is configured to supply a first gas. The first gas line is coupled to a multichannel splitter spool with a plurality of second gas lines into which the first gas flows. Each gas line of the plurality of second gas lines will have a smaller volume than the volume of the first gas line. The smaller second gas lines will be wrapped by a heater jacket. Due to the smaller volume of the second gas lines, when the first gas is flowed through the second gas lines, the heater jacket will sufficiently heat the first gas, eliminating the condensation induced particle defects that occur in conventional gas line systems when the first gas meets with a second gas in the gas line system.

  • Patent number: 11145504
    Abstract: A method of forming a film stack with reduced defects is provided and includes positioning a substrate on a substrate support within a processing chamber and sequentially depositing polysilicon layers and silicon oxide layers to produce the film stack on the substrate. The method also includes supplying a current of greater than 5 ampere (A) to a plasma profile modulator while generating a deposition plasma within the processing chamber, exposing the substrate to the deposition plasma while depositing the polysilicon layers and the silicon oxide layers, and maintaining the processing chamber at a pressure of greater than 2 Torr to about 100 Torr while depositing the polysilicon layers and the silicon oxide layers.
