Abstract: A surgical instrument includes a rod and a push portion. The push portion includes a first end connected to an end of the rod and a second end having a blade portion. The push portion includes a plurality of grooves. The plurality of grooves is recessed in a surface of the push portion and is spaced from each other. Each two adjacent grooves has a rib formed therebetween. A top face of a cross section of each rib is the surface of the push portion. Each rib has a guiding face on the cross section of the push portion. The guiding face is connected to the surface of the push portion. The guiding face faces a rotating direction of the rod. An angle between the guiding face and the surface of the push portion in the cross section is greater than 90°.

Abstract: A semiconductor structure and a method for forming the same are provided. The method includes following steps. A gate electrode layer is formed on a substrate. A spacer structure is formed on a sidewall of the gate electrode layer. A dielectric cap film is formed to cover the gate electrode layer and the spacer structure. A source/drain implantation is performed to the substrate with the dielectric cap film exposed to a condition of the source/drain implantation.

Abstract: A manufacturing method for a semiconductor device includes: providing a substrate including a first gate structure disposed thereon, wherein the first gate structure includes a first gate electrode and a first hard mask covers the first gate electrode. A first oxide spacer and a silicon carbon nitride spacer are formed in sequence to surround the first gate electrode. A thermal treatment is performed to form a silicon oxycarbonitride layer between the first oxide spacer and the silicon carbon nitride spacer. Then, a second oxide spacer, a third oxide spacer, and a first silicon nitride spacer are formed on the silicon carbon nitride spacer in sequence. The first hard mask and the first silicon nitride spacer are removed. Finally, the third oxide spacer, the second oxide spacer, and silicon carbon nitride spacer are removed entirely to expose the silicon oxycarbonitride layer.

Abstract: A method for fabricating a semiconductor device is described. A semiconductor substrate is provided, wherein the substrate has a first area and a second area. A first gate structure and a second gate structure are formed over the substrate in the first area and the substrate in the second area, respectively. A first spacer is framed on the sidewall of each gate structure. At least one etching process including at least one wet etching process is performed. The first spacer is removed. A second spacer is formed on the sidewall of each gate structure. A mask layer is formed in the second area. Ion implantation is formed using the mask layer, the first gate structure and the second spacer as a mask to form S/D extensions in the substrate beside the first gate structure in the first area. The mask layer is then removed.

Abstract: A motorcycle low-profile positioning creeper allows a medium to large motorcycle to be easily mounted on the positioning creeper and easily moved to any desired position on a horizontal surface such as a showroom floor or storage area. The positioning creeper comprises a low slung H-frame body and four rotatable wheels. The low slung H-frame body is a plate and comprises four corners and four protrusions. The four protrusions protrude upward and outward respectively from the corners and are separated from adjacent longitudinal protrusions a distance greater than a motorcycle tire width. The four rotatable wheels are mounted respectively under the four protrusions.

Abstract: A motorcycle side kickstand dolly used with one or two conventional wheel dollies that allows a medium to large motorcycle to be mounted easily on the dollies and moved easily to any desired position on a horizontal surface. The motorcycle side kickstand dolly in accordance with the present invention comprises an H-frame support panel, a side kickstand brace and four wheels. The H-frame support panel comprises a low-slung panel and four protrusions. The low-slung panel has four corners. The protrusions are formed respectively on the corners and protrude up and out from the corners. The side kickstand brace is mounted on the low-slung panel between two adjacent protrusions and has an upper edge, a recess and a strengthening lip. The recess is formed downward from the upper edge. The strengthening lip is formed on and protrudes transversely from the upper edge. The wheels are mounted rotatably respectively under the protrusions.
