Provided is a firing weapon simulation system simulating leading firing. The firing weapon simulation system is configured to include laser firing apparatus mounted on a firing weapon and a target sensing apparatus attached to a target. The laser firing apparatus includes a first control unit, a firing switch which is driven cooperatively with firing of the firing weapon, an image processing unit which measuring a leading angle from an image including the moving target, a first GPS receiver, a laser beam firer, and a motor assembly which rotates the laser beam firer. When the firing switch is switched on, the first control unit generates the firing data, allows the motor assembly to reversely rotate the laser beam firer by a measured value of the leading angle, and allows the laser beam firer to emit the laser beam carrying the firing data. The target sensing apparatus includes a second control unit, a sensing circuit unit which extracts firing data from the laser beam, a second GPS receiver, and a hitting situation indicator which indicates hitting result according to a driving signal transmitted from the second control unit. The second control unit solves simultaneous equations of the trajectory equation of the firing weapon and the equation of motion of the target to determine whether or not the target is hit and outputs a result of the determination to the hitting situation indicator.

An integrated circuit device includes a substrate through which a first through-hole extends, and an interlayer insulating film on the substrate, the interlayer insulating film having a second through-hole communicating with the first through-hole. A Through-Silicon Via (TSV) structure is provided in the first through-hole and the second through-hole. The TSV structure extends to pass through the substrate and the interlayer insulating film. The TSV structure comprises a first through-electrode portion having a top surface located in the first through-hole, and a second through-electrode portion having a bottom surface contacting with the top surface of the first through-electrode portion and extending from the bottom surface to at least the second through-hole.

A semiconductor device includes a via structure and a conductive structure. The via structure has a surface with a planar portion and a protrusion portion. The conductive structure is formed over at least part of the planar portion and not over at least part of the protrusion portion of the via structure. For example, the conductive structure is formed only onto the planar portion and not onto any of the protrusion portion for forming high quality connection between the conductive structure and the via structure.

In a method of manufacturing a semiconductor device, a front end of line (FEOL) process may be performed on a semiconductor substrate to form a semiconductor structure. A back end of line (BEOL) process may be performed on the semiconductor substrate to form a wiring structure electrically connected to the semiconductor structure, thereby formed a semiconductor chip. A hole may be formed through a part of the semiconductor chip. A preliminary plug may have a dimple in the hole. The preliminary plug may be expanded into the dimple by a thermal treatment process to form a plug. Thus, the plug may not have a protrusion protruding from the upper surface of the semiconductor chip, so that the plug may be formed by the single CMP process.

A method of forming a semiconductor device can include forming a trench in a semiconductor substrate to define an active region. The trench is filled with a first device isolation layer. A portion of the first device isolation layer is etched to recess a top surface of the first device isolation layer below an adjacent top surface of the active region of the semiconductor substrate and to partially expose a sidewall of the active region. The exposed sidewall of the active region is epitaxially grown to form an extension portion of the active region that extends partially across the top surface of the first device isolation layer in the trench. A second device isolation layer is formed on the recessed first device isolation layer in the trench. The second device isolation layer is etched to expose a top surface of the extension portion of the active region and leave a portion of the second device isolation layer between extension portions of active regions on opposite sides of the trench. An interlayer dielectric is formed on the semiconductor substrate and the second device isolation layer. A conductive contact is formed extending through the interlayer dielectric layer and directly contacting at least a portion of both the active region and the extension portion of the active region overlying the second device isolation layer.

A speaker apparatus includes a speaker frame, an acoustic vibrating plate movably supported on the speaker frame, and a magnetic driver formed in the speaker frame for vibrating the acoustic vibrating plate. The magnetic driver is connected such that it may vibrate different portions of the acoustic vibrating plate independently. The acoustic vibrating plate of the speaker apparatus may vibrate with the same phase, thereby increasing sound pressure and improving acoustic efficiency.
