  • Publication number: 20240153901
    Abstract: A first and second semiconductor device are bonded together using a bonding contact pad embedded within a bonding dielectric layer of the first semiconductor device and at least one bonding via embedded within a bonding dielectric layer of the second semiconductor device. The bonding contact pad extends a first dimension in a first direction perpendicular to the major surface of the first semiconductor device and a second dimension in a second direction parallel to the plane of the first semiconductor wafer, the second dimension being at least twice the first dimension. The bonding via extends a third dimension in the first direction and a fourth dimension in the second direction, the third dimension being at least twice the first dimension. The bonding contact pad and bonding via may be at least partially embedded in respective bonding dielectric layers in respective topmost dielectric layers of respective stacked interconnect layers.

  • Publication number: 20240096830
    Abstract: A method includes forming a first sealing layer at a first edge region of a first wafer; and bonding the first wafer to a second wafer to form a wafer stack. At a time after the bonding, the first sealing layer is between the first edge region of the first wafer and a second edge region of the second wafer, with the first edge region and the second edge region comprising bevels. An edge trimming process is then performed on the wafer stack. After the edge trimming process, the second edge region of the second wafer is at least partially removed, and a portion of the first sealing layer is left as a part of the wafer stack. An interconnect structure is formed as a part of the second wafer. The interconnect structure includes redistribution lines electrically connected to integrated circuit devices in the second wafer.

  • Patent number: 11236967
    Abstract: A pistol frame is suitable for mounting of a trigger mechanism which includes a trigger mechanism housing having a through channel. The pistol frame includes an upper frame portion defining a rear receiving space, and a rear rail block disposed in the rear receiving space and including a bottom plate, and two side plates extending upwardly the bottom plate. Each side plate has a through hole suitable for aligning with the through channel to permit extension of a trigger housing pin therethrough to thereby fix the rear rail block and the trigger mechanism housing to the upper frame portion. The bottom plate and the side plates cooperatively define at least one receiving space suitable for receiving the extensions.
