A recently granted patent (Publication Number: US11923460B2) discloses a semiconductor structure comprising semiconductor stacks over a substrate. Each stack includes channel layers and a gate structure with gate dielectric layers and a gate electrode. The unique feature of this structure is the varying space between the channel layers in the vertical direction, with the lowermost layers having a greater space compared to the uppermost layers. This difference in spacing is crucial for the performance of the semiconductor structure and falls within a specific range of 5 nm to 30 nm.

Furthermore, the patent claims detail the composition of the gate electrode, including work function tuning layers and a metal filling layer. The spaces between adjacent work function tuning layers and the uppermost channel layers are filled with specific materials to optimize the functionality of the semiconductor structure. Additionally, the patent covers variations in the composition of the channel layers within the semiconductor stacks, allowing for flexibility in material selection based on specific requirements. Overall, the patented semiconductor structure offers a novel design with precise spacing and composition considerations to enhance performance and efficiency in semiconductor applications.
