  • Patent number: 11823989
    Abstract: A method includes etching a substrate to form an opening, depositing a first dielectric liner extending into the opening, and depositing a second dielectric liner over the first dielectric liner. The second dielectric liner extends into the opening. A conductive material is filled into the opening. The method further includes performing a first planarization process to planarize the conductive material so that a portion of the conductive material in the opening forms a through-via, performing a backside grinding process on the substrate until the through-via is revealed from a backside of the substrate, and forming a conductive feature on the backside of the substrate. The conductive feature is electrically connected to the through-via.

  • Patent number: 11818534
    Abstract: A dual omnidirectional microphone array noise suppression is described. Compared to conventional arrays and algorithms, which seek to reduce noise by nulling out noise sources, the array of an embodiment is used to form two distinct virtual directional microphones which are configured to have very similar noise responses and very dissimilar speech responses. The only null formed is one used to remove the speech of the user from V2. The two virtual microphones may be paired with an adaptive filter algorithm and VAD algorithm to significantly reduce the noise without distorting the speech, significantly improving the SNR of the desired speech over conventional noise suppression systems.
