  • Patent number: 11991433
    Abstract: Examples disclosed herein provide a computing device. As an example, the computing device includes a housing having an opening extending through the housing, to accommodate a lens of a camera. The computing device includes a shutter to selectively obscure the opening, where the shutter is slidable between a first position and a second position. While in the first position, the shutter is to obscure the opening while a microphone of the computing device is enabled and, while in the second position, the shutter is to obscure the opening and disable the microphone.

  • Publication number: 20240162269
    Abstract: Some embodiments relate an integrated circuit (IC) including a first substrate. An interconnect structure is disposed over the first substrate. The interconnect structure includes a plurality of metal features that are stacked over one another. A lowermost metal feature of the plurality of metal features is closest to the first substrate, an uppermost metal feature of the plurality of metal features is furthest from the first substrate, and intermediate metal features are disposed between the lowermost metal feature and the uppermost metal feature. A recess extends into the interconnect structure and terminates at a bond pad. A lower surface of the bond pad directly contacts an upper surface of the lowermost metal feature.

  • Patent number: 11984465
    Abstract: The present disclosure relates to a CMOS image sensor having a multiple deep trench isolation (MDTI) structure, and an associated method of formation. In some embodiments, the image sensor comprises a boundary deep trench isolation (BDTI) structure disposed at boundary regions of a pixel region surrounding a photodiode. The BDTI structure has a ring shape from a top view and two columns surrounding the photodiode with the first depth from a cross-sectional view. A multiple deep trench isolation (MDTI) structure is disposed at inner regions of the pixel region overlying the photodiode, the MDTI structure extending from the back-side of the substrate to a second depth within the substrate smaller than the first depth. The MDTI structure has three columns with the second depth between the two columns of the BDTI structure from the cross-sectional view. The MDTI structure is a continuous integral unit having a ring shape.
