Abstract: A semiconductor device includes a substrate, a dielectric layer disposed over the substrate, and an interconnect structure extending through the dielectric layer. The dielectric layer includes a low-k dielectric material which includes silicon carbonitride having a carbon content ranging from about 30 atomic % to about 45 atomic %. The semiconductor device further includes a thermal dissipation feature extending through the dielectric layer and disposed to be spaced apart from the interconnect structure.

Abstract: The present disclosure provides a thin film including a first thermoplastic polyolefin (TPO) elastomer which is anhydride-grafted. The present disclosure further provides a method for manufacturing the thin film, a laminated material and a method for adhesion.

Abstract: A method of purifying yttrium involves purifying element yttrium by high-temperature saturated dissolution, low-temperature recrystallization, high-temperature reduction and vaporization-based removal of impurities, in a simple manner, and at a low cost, such that yttrium element is unlikely to be contaminated by any raw material used in a manufacturing process.

Abstract: A method for decomposing plastic waste to produce fuel materials makes the plastic waste decomposed by cracking and then inverted the plastic waste to be multiple fuel materials such as gas, gasoline, and diesel oil, and other byproducts such as hydrochloride acid and active carbon by fractionation. Whereby, the plastic waste is reused in an efficient and beneficial way.

Abstract: A scooter includes a handle secured to the front portion of a board and rotatably relative to the board between an upright working position and a lowered folding position. A latch ring is slidably engaged on the handle and selectively engaged with the seat for securing the handle to the board at the upright working position and the lowered folding position. The latch ring includes one or more projections for engaging into the seat and for solidly securing the handle to the seat. A fastener or a quick release locking device may solidly secure the latch ring to the handle.
