Abstract: A device includes: a stack of semiconductor nanostructures; a gate structure wrapping around the semiconductor nanostructures, the gate structure extending in a first direction; a source/drain region abutting the gate structure and the stack in a second direction transverse the first direction; a contact structure on the source/drain region; a backside conductive trace under the stack, the backside conductive trace extending in the second direction; a first through via that extends vertically from the contact structure to a top surface of the backside dielectric layer; and a gate isolation structure that abuts the first through via in the second direction.

Abstract: A lens barrel includes a front end portion. The front end portion includes an outer surface facing toward an object side and an inner surface facing toward an image side. The inner surface includes an inner side conical surface. The inner side conical surface is connected to the outer surface. The inner-side conical surface includes a plurality of toothed structures, an inner edge near an optical axis and an outer edge away from the optical axis. The outer edge is closer to the image side than the inner edge. The inner edge forms a clear hole. Each of the toothed structures includes a tooth peak and a tooth valley. The tooth peak and the tooth valley are disposed at the inner edge, and the tooth peak extends from the inner edge to the outer edge to form a convex strip.

Abstract: A modular output device comprises a mainboard, a first assembling component, and a second assembling component. The first assembling component is configured in a first assembly structure of the mainboard, and a first connection module of the first assembling component is electrically connected to a first electrical connector, which allows a master function module and a first function module to transmit data to each other. The second assembling component is configured in a second assembly structure, and a second connection module is electrically connected to a second electrical connector, which allows the master function module and a second function module to transmit data to each other. In this way, the first function module and the second function module can transmit data to an associated computer through the main function module.

Abstract: A hard disc bracket is provided for fixing a hard disc within a computer case. The hard disc bracket includes a main frame and an auxiliary frame. The main frame has at least one opening. The auxiliary frame has at least one hook corresponding to the at least one opening and has at least one positioning post. After the auxiliary frame and the hard disc are combined together through the at least one positioning post, the at least one hook is engaged with the corresponding opening, so that the hard disc is fixed on the hard disc bracket. Consequently, the hard disc may be fixed on the hard disc bracket without the need of using a screwdriver or any other tool.

Abstract: A hard disc bracket is provided for fixing a hard disc within a computer case. The hard disc bracket includes frame body, a frame lateral plate, a receiving space, and at least one hook. The receiving space is defined by the frame body and the frame lateral plate collaboratively. The at least one hook is located at an upper edge of the frame lateral plate. When the hard disc is accommodated within the receiving space, the at least one hook is engaged with the hard disc to fix the hard disc on the frame body. Consequently, the hard disc may be fixed on the hard disc bracket without the need of using a screwdriver or any other tool.

Abstract: A hard disc bracket is provided for fixing a hard disc within a computer case. The hard disc bracket includes a frame, at least one pushing lever, and a pulling lever. The at least one pushing lever is located at a side of the frame and rotatable relative the frame. The pulling lever is disposed on the frame and movable relative to the frame. When the frame is stored within the computer case and the pulling lever is pulled out, the at least one pushing lever is moved by the pulling lever and rotated relative to the frame, so that the computer case is pushed by the at least one pushing lever and the frame is detached from the computer case.
