Abstract: A method includes bonding a first wafer to a second wafer, with a first plurality of dielectric layers in the first wafer and a second plurality of dielectric layers in the second wafer bonded between a first substrate of the first wafer and a second substrate in the second wafer. A first opening is formed in the first substrate, and the first plurality of dielectric layers and the second wafer are etched through the first opening to form a second opening. A metal pad in the second plurality of dielectric layers is exposed to the second opening. A conductive plug is formed extending into the first and the second openings.

Abstract: An adjustable attachment device includes a clamping member for securely clamping a tubular member, a sleeve securely mounted to the clamping member, a ball received in the sleeve, a connecting seat having a portion securely coupled to the ball to move therewith, and a resilient member. The sleeve includes a longitudinal through-hole. Further, the sleeve includes a cutout passing through an upper end of the longitudinal through-hole. The resilient member biases the ball to press against a spherical upper wall section of the sleeve, thereby retaining the connecting seat in place. The connecting seat is pressable to compress the resilient member and cause the ball to disengage from the spherical upper wall section of the sleeve, allowing the connecting seat to move along the cutout of the sleeve and allowing the connecting seat to turn to a desired orientation relative to the tubular member.

Abstract: A packaging carton is disclosed, suitable for packaging an electronic product, such as a peripheral product, a mobile phone, or a spare part. The packing carton is formed by folding a paper material and is one piece, and is fabricated by linking two clip slots. Furthermore, the packaging carton comprises two hollow buffer structures beside two sides of a storage chamber and two upper holding pieces adjacent to both sides of the storage chamber to protect an object packaged in the packaging carton.

Abstract: A portable accessory box is disclosed. The portable accessory box comprises: a bottom plate; two side rectangular bodies fixedly connected to two sides of the bottom plate; and a lower side plate fixedly connected to the lower side of the bottom plate. The portable accessory box can further comprise an upper side plate fixedly connected to the upper side of the bottom plate. The bottom plate includes a hand-held hole for carrying and two fixed pieces used to fix the side rectangular bodies. In addition, each of the side rectangular bodies comprises an embedded slot, and the lower side plate and the upper side plate both include an inner side piece. When the lower side plate and the upper side plate are folded inwardly, the inner side pieces can be embedded into the embedded slots of the side rectangular bodies to divide each of the side rectangular bodies into two rectangular sub-bodies and form a lower rectangular body and an upper rectangular body between the side rectangular bodies.
