Abstract: A semiconductor device including a substrate, a low-k dielectric layer, a cap layer, and a conductive layer is provided. The low-k dielectric layer is disposed over the substrate. The cap layer is disposed on the low-k dielectric layer, wherein a carbon atom content of the cap layer is greater than a carbon atom content of the low-k dielectric layer. The conductive layer is disposed in the cap layer and the low-k dielectric layer.

Abstract: A method for preparing a patterned target layer is provided. A target layer is formed over a substrate. A multi-layered hard mask layer is formed over the target layer. The multi-layered hard mask layer includes a first hard mask layer over the target layer, a second hard mask layer between the target layer and the first hard mask layer, and a third hard mask layer between the target layer and the second hard mask layer, wherein a material of the second hard mask layer is different from a material of the first hard mask layer and a material of the third hard mask layer. The multi-layered hard mask layer is used as a hard mask layer to prepare a fine pattern on the target layer.

Abstract: A wall mount assembly includes a first engagement member and a second engagement member. The first engagement member includes a slide structure and two positioning indentations oppositely disposed relative to the slide structure. The second engagement member includes a slider and two positioning bosses oppositely disposed relative to the slider. The first engagement member and the second engagement member are capable of being correspondingly disposed on an object and a wall. When the slider enters the slide structure from an entrance of the slide structure and is confined to slide relative to the slide structure so as to be blocked at a stop position of the slide structure, the two positioning bosses are embedded in the two positioning indentations respectively so that the object can be fixed on the wall stably. Therefore, the wall mount assembly simplifies the wall-mount operation of the object and provides a stable wall-mount effect.

Abstract: A dustproof transceiver includes a transceiver body, a first dustproof cover and a second dustproof cover. The transceiver body has an opening to receive an optical fiber connector. The first dustproof cover is pivotally connected on the transceiver body to swivel and shelter a part of the opening. The second dustproof cover slides on the transceiver body to shelter the remaining part of the opening. A spring is secured to the transceiver body at one end and secured to the second dustproof cover at an opposite end. A rebounding member has two spiral springs, two securing ends and a securing section linking the two spiral springs. The two securing ends are respectively coupled to the transceiver body and the securing section is coupled to the first dustproof cover such that the rebounding member exerts a force on the first dustproof cover to shelter the part of the opening.
