The patent application (Publication Number: US20240038832A1) describes a semiconductor device with a unique configuration. The device includes a substrate with at least one trench, a high-Q capacitor on the surface of the substrate, and an ultra-high-density capacitor in the trench. The capacitors consist of electrodes and dielectric layers, with interconnections linking them. Additionally, a barrier layer is present between the substrate surface and the bottom electrode, as well as between the trench inner surface and the first electrode. The device's design allows for efficient use of space and improved performance.

The manufacturing method outlined in the patent involves forming the trench in the substrate, applying barrier and metal layers, and patterning to create the electrodes and interconnections. The process includes steps such as patterning the dielectric layer to remove material between the electrodes and forming an interlayer dielectric layer. By incorporating a complementary metal-oxide-semiconductor process and interlayer dielectric layers, the method ensures the proper functioning of the semiconductor device. Overall, the innovative design and manufacturing process detailed in the patent aim to enhance the performance and efficiency of semiconductor devices.
