  • Publication number: 20250089229
    Abstract: Various embodiments of the present disclosure are directed to a vertical gate-all-around (GAA) memory cell. A middle conductor overlies a lower conductor and decreases in width towards the lower conductor to culminate in a point spaced from the lower conductor. An insulator structure is between the lower conductor and the middle conductor. A semiconductor channel overlies the middle conductor, and a gate electrode laterally surrounds the semiconductor channel on a sidewall of the semiconductor channel. A gate dielectric layer separates the gate electrode from the semiconductor channel, and an upper conductor overlies the semiconductor channel. The lower and middle conductors and the insulator structure correspond to a resistor, whereas the middle conductor, the upper conductor, the gate electrode, the gate dielectric layer, and the semiconductor channel correspond to a transistor atop the resistor.

  • Publication number: 20250072143
    Abstract: An electrode controls transmittance of a blocking layer over a photodiode of a pixel sensor (e.g., a photodiode of a small pixel detector) by changing oxidation of a metal material included in the blocking layer. By using the electrode to adjust transmittance of the blocking layer, pixel sensors for different uses and/or products may be produced using a single manufacturing process. As a result, power and processing resources are conserved that otherwise would have been expended in switching manufacturing processes. Additionally, production time is decreased (e.g., by eliminating downtime that would otherwise have been used to reconfigure fabrication machines.
