  • Patent number: 11495451
    Abstract: A non-transitory medium includes instructions to control a spin coating device to render a cleaning nozzle of the spin coating device below a base plate and out of optimal exposure to a substrate material placed on a spin chuck when the base plate is engaged with the spin chuck. In response to disengagement of a lid from the base plate, the non-transitory medium also includes instructions to disengage the base plate from the spin chuck to lower the base plate to a locking point whereupon a portion of the cleaning nozzle below the base plate passes through a hole in the base plate and emerges completely out of and above the base plate, and instructions to clean the bottom surface and/or the edges of the substrate material utilizing the cleaning nozzle based on an optimal exposure to the bottom surface and the edges of the substrate material.

  • Patent number: 11239070
    Abstract: A method includes rendering a cleaning nozzle of a spin coating device below a base plate and out of optimal exposure to a bottom surface and edges of a substrate material placed on a spin chuck in a state of engagement of the base plate with the spin chuck, and rendering the base plate completely under the spin chuck even in the aforementioned state of engagement. In response to disengagement of a lid from the base plate, the method also includes disengaging the base plate from the spin chuck to lower the base plate to a locking point whereupon a portion of the cleaning nozzle below the base plate passes through a hole in the base plate and emerges completely out of and above the base plate, and cleaning the bottom surface and/or the edges of the substrate material utilizing the cleaning nozzle based on an optimal exposure thereof.

  • Patent number: 11133499
    Abstract: Substituted ramsdellite manganese dioxide (R—MnO2) compounds are provided, where a portion of the Mn is replaced by at least one alternative cation, or a portion of the O is replaced by at least one alternative anion. Electrochemical cells incorporating substituted R—MnO2 into the cathode, as well as methods of preparing the substituted R—MnO2, are also provided.

  • Patent number: 10679844
    Abstract: A spin coating device includes a base plate, a spin chuck on which a substrate material is placed, and an actuator mechanism to engage the base plate with the spin chuck such that the base plate synchronously spins along with the spin chuck. The substrate material includes a top surface coated with a film-forming substance and a bottom surface. The cleaning mechanism is below the base plate and out of optimal exposure to the bottom surface and edges of the substrate material in a state of base plate engagement. In response to disengagement of a lid configured to synchronously co-rotate with the base plate, the actuator mechanism is further configured to disengage the base plate from the spin chuck and to enable the optimal exposure of the cleaning mechanism to the bottom surface and the edges of the substrate material.
