Abstract: A method for producing graphene, configured for forming a graphene layer on a surface of an object. The method includes steps of: depositing a poly-p-xylene material layer on the surface: and converting the poly-p-xylene material layer into a graphene layer by using a laser sintering process or a plasma-assisted sintering process.

Abstract: A method of forming an IC structure includes forming first and second power rails at a power rail level. First metal segments are formed at a first metal level above the power rail level. Each first metal segment of the plurality of first metal segments overlap one or both of the first power rail or the second power rail. First vias are formed between the power rail level and the first metal level. Second metal segments are formed at a second metal level above the first metal level. At least one second metal segment of the plurality of second metal segments overlaps the first power rail. At least one second metal segment of the plurality of second metal segments overlaps the second power rail. A plurality of second vias are formed between the first metal level and the second metal level.

Abstract: A screw driver including a sleeve having a handle coupled to one end and having a number of teeth formed in the inner surface, a shaft rotatably received in the sleeve, a pawl rotatably engaged in the head, a rod rotatably received in the shaft, a spring and a ball received in the rod and the ball being biased to engage with the pawl, a knob engaged on the shaft, a post engaged through the knob and the shaft and the rod so that the rod can be rotated by the knob, and the pawl being caused to engage with the teeth of the sleeve when the rod is rotated in either direction.
