  • Patent number: 12322699
    Abstract: Embodiments of the invention describe low capacitance interconnect structures for semiconductor devices and methods for manufacturing such devices. According to an embodiment of the invention, a low capacitance interconnect structure comprises an interlayer dielectric (ILD). First and second interconnect lines are disposed in the ILD in an alternating pattern. The top surfaces of the first interconnect lines may be recessed below the top surfaces of the second interconnect lines. Increases in the recess of the first interconnect lines decreases the line-to-line capacitance between neighboring interconnects. Further embodiments include utilizing different dielectric materials as etching caps above the first and second interconnect lines. The different materials may have a high selectivity over each other during an etching process. Accordingly, the alignment budget for contacts to individual interconnect lines is increased.

  • Publication number: 20250022403
    Abstract: Technology for a display controller is described. The display controller can detect a frame update when the display controller is in a dynamic sleep state. The display controller can wake up from the dynamic sleep state and enter a selective update state at a programmed vertical blanking interrupt (VBI) that precedes an actual VBI. The display controller can perform a scan-out with a display panel during the selective update state. The display controller can return to the dynamic sleep state in a same time frame after the scan-out is completed. The display controller can exclude timing logic to send a VBI at every time frame to the display panel to maintain time synchronization between the display controller and the display panel.
