Abstract: A device includes a semiconductor substrate, a fin structure on the semiconductor substrate, a gate structure on the fin structure, and a pair of source/drain features on both sides of the gate structure. The gate structure includes an interfacial layer on the fin structure, a gate dielectric layer on the interfacial layer, and a gate electrode layer of a conductive material on and directly contacting the gate dielectric layer. The gate dielectric layer includes nitrogen element.

Abstract: This invention is an improved painting tool structure, consisting of a body and a knife board. The body comprises a grip part and a bottom plate. The grip part protrudes from the upper surface of one end of the bottom plate, whereas a clamping slot with an opening facing downward is disposed between the grip part and the bottom plate. The bottom plate and the clamping slot form an angle of less than 90 degrees. The knife board comprises a blade part and a connecting part, where the connecting part 22 is obliquely extended upward from one end of the blade part to form an angle of less than 90 degrees, and is to be connected to the clamping slot.

Abstract: This invention is a multi-functional tool structure, consisting of a handle, a base, a cover and a sleeve. The base is engaged to the handle, and has multiple slots for placing tool heads, while the bottom part is provided with tool positioning recesses for fixing tool heads. The sleeve is set on the base, and has a side opening. Hence, when the side opening is set in line with the too heads by the rotation of the sleeve, the tool head can be removed from the side opening, and fixed to the tool fixing recess on the base before use.

Abstract: A caulking assisting device has of a fixed frame mounted to a filler coating-supplying device, a rolling part mounted to the fixed frame, a movable frame and an elastic element. The positioning frame has a pair of first limiting recesses and a pair of second limiting recesses. The movable frame is pivoted to the fixed frame and is rotatable, and a tapered roller is pivoted at the end of the movable frame. Meanwhile, the elastic element is disposed on the movable frame, while a positioning protrusion is located at both ends respectively. As a result, the tapered roller can be moved to a use position and a non-use position by the rotation of the movable frame, thereby switching between the rolling part and the tapered roller while in use.
