Abstract: A method of forming a semiconductor device includes: forming a fin protruding above a substrate, where a top portion of the fin comprises a layer stack that includes alternating layers of a first semiconductor material and a second semiconductor material; forming a dummy gate structure over the fin; forming openings in the fin on opposing sides of the dummy gate structure; forming source/drain regions in the openings; removing the dummy gate structure to expose the first semiconductor material and the second semiconductor material under the dummy gate structure; performing a first etching process to selectively remove the exposed first semiconductor material, where after the first etching process, the exposed second semiconductor material form nanostructures, where each of the nanostructures has a first shape; and after the first etching process, performing a second etching process to reshape each of the nanostructures into a second shape different from the first shape.

Abstract: An apparatus includes a vacuum chamber, a reflective optical element arranged in the vacuum chamber and configured to reflect an extreme ultra-violet (EUV) light, and a cleaning module positioned in the vacuum chamber. the cleaning module is operable to provide a mitigation gas flowing towards the reflective optical element and provide a hydrogen-containing gas flowing towards the reflective optical element. The mitigation gas mitigates, by chemical reaction, contamination of the reflective optical element.

Abstract: An auto-mute control circuit is disclosed. The auto-mute control circuit includes an analog amplifier, a detecting circuit and a direct-current (DC) level adjusting circuit. The analog amplifier receives an input signal and outputs a sensing voltage signal accordingly. The detecting circuit compares a common-mode voltage received with the sensing voltage signal received and outputs a comparison signal accordingly. The DC adjusting circuit receives the comparison signal and outputs an Up-Down digital signal, a fine tune digital signal and a rough tune digital signal, so that a sensing DC level is equal to the common-mode voltage.

Abstract: The present invention relates to a quick manhole/handhole construction method and related devices, which mainly comprises a cutting unit and a manhole/handhole cover lifter. The cutting unit is mainly composed of a radial feeding device, a cutting plate, a base, and a vessel, and makes the user proceed the cutting task easily by fixing the base and operating the radial feeding device. The main part of the lifter is a single frame, and can be used to lift a manhole/handhole effortlessly due to the principle of the lever. According to the cutting unit and the lifter of a manhole/handhole cover with applying the construction steps for the present invention, the replacement of a manhole/handhole can be done quickly.

Abstract: A vibration resistant expansion joint is provided. The expansion joint includes a sustaining pedestal (1) which is formed from two L-shaped members (111 and 112). A plurality of shim assemblies (12), each containing a bifurcated tooth-like shim (121), are pivotally joined to the sustaining pedestal (1). Additionally provided is a foundation (3) formed of two L-shaped side members, each side member having a slide surface (33, 34) formed along a bottom edge thereof. A stepped bench unit (2), formed of a pair of benches, is slidably mounted on foundation (3).

Abstract: An expansion joint in which by means of movability of expansion shim assemblies in a sustaining pedestal and a stepped bench unit formed of a pair of benches at different elevation disposed beneath the sustaining pedestal so as to withstand vibration of roadway or bridge and instantly rescue the roadway or bridge from collapsing.

Abstract: A quick release lock for a cover is provided. The cover may be a manhole cover for closing onto a manhole ring having a radially extended flange. The quick release lock mainly includes several angularly equal-spaced cross-shaped slots provided on the cover to communicate with through holes below them, and catch elements, push elements, and cotters in the same number as that of the cross-shaped slots. The catch element each is pivotally connected to and between two fixing plates provided at two opposite sides of each through hole. The cotter each is positioned in one cross-shaped slot and extended down into she through hole. The push element each is screwed on a bar portion of the cotter below the cover. When the cotter is depressed, the push element radially pushes the catch element outward to engage with a lower edge of the flange on the ring member and thereby firmly locks the cover to the ring member.

Abstract: A rapidly adjustable man-hole cover seat for sustaining the alignment of a road surface and a man-hole cover, comprises a base, an adjustable seat, a man-hole cover and a cruciform hole fixing frame, a stud block, a supporting block, etc. In a large distance adjustment, the inner rim of the adjustable seat is designed so that it may be penetrated by adjustable screws. Thus the adjustable seat may be adjusted and moved for aligning with the road surface. In another small distance adjustment, a cruciform hole fixing frames are installed on the bottom of the adjustable seat for being penetrated by screws so as to be installed on the base. Further, supporting blocks are installed for distributing the weight borne by the adjustable seat, the stud block and screws so that the man-hole cover may suffer a heavy pressure and the steadiness of the man-hole cover and road surface as cars are passing is sustain.
