  • Patent number: 11652162
    Abstract: A simplified method for forming a non-volatile memory cell using two polysilicon depositions. A first polysilicon layer is formed on and insulated from the semiconductor substrate in a first polysilicon deposition process. An insulation block is formed on the first polysilicon layer. Spacers are formed adjacent first and second sides of the insulation block, and with the spacer adjacent the first side is reduced. Exposed portions of the first poly silicon layer are removed while maintaining a polysilicon block of the first polysilicon layer disposed under the insulation block. A second polysilicon layer is formed over the substrate and the insulation block in a second polysilicon deposition process. Portions of the second polysilicon layer are removed while maintaining a first polysilicon block (disposed adjacent the first side of the insulation block), and a second polysilicon block (disposed adjacent the second side of the insulation block).

  • Publication number: 20230079046
    Abstract: One or more methods of designing an FC bipolar plate that enhance the operational performance of FC. A first image analysis is conducted of image data of a fluid flow field structure having one or more dehomogenized microstructures to identify channels having a fluid flow blockage at a channel wall dead-end. The channel wall dead-end of each identified channel is selectively removed in a manner that fluidically connects each identified channel to an adjacent channel. Then, a second image analysis of the image data is conducted in response to selectively removing the channel wall dead-ends to measure a length of each channel wall. Channels walls having a length greater than a threshold channel wall length value are selectively cut, thereby providing reduced fluid flow resistance throughout the FC.
