According to the present invention, a semiconductor device comprises an active region formed in a substrate, and including flat surfaces and hole-shaped recess portions; upper-level plugs disposed over the flat surfaces; a spacer disposed between the upper-level plugs and providing a trench exposing the hole-shaped recess portions; a lower-level plug filling the hole-shaped recess portions; and a buried conductive line disposed over the lower-level plug and partially filling the trench.

Abstract: A connection structure of a stator of a drive motor is configured to allow coils to be wound in a plurality of slots provided in a stator core and to connect the coils withdrawn from the slots. The coils are wound in the slots to form first-type structures and second-type structures configured such that withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the first-type structures are opposite to withdrawal directions of three-phase (U-, W- and V-phase) withdrawal lines and N-phase withdrawal lines withdrawn from the slots of the second-type structures. The first-type structures and the second-type structures are disposed symmetrically to each other with respect to a reference line formed to divide the slots in half.

Abstract: Disclosed in the present invention is a floating hologram system. The floating hologram system includes a diffuser configured to form a projection image using light beams transmitted from an image transmitter and diffuse the formed image, and a holographic optical element on which the image diffused from the diffuser is incident and which generates a virtual image floating at a position a predetermined distance therefrom and has a convex lens characteristic. A distance between the diffuser and the holographic optical element is determined based on a focal length of the holographic optical element and a distance from the holographic optical element to the virtual image.

Abstract: In an embodiment, a polyphenylene oxide resin composition includes 24% by weight to 52% by weight of polyphenylene oxide (PPO), 13% by weight to 39% by weight of high Impact polystyrene (HIPS), 20% by weight to 25% by weight of inorganic filler, 5% by weight to 10% by weight of inorganic reinforcing material and 5% by weight to 10% by weight of impact modifier.

Abstract: An electromagnetic-wave-transmissive module of a vehicle radar is provided to minimize a dielectric impact reflection effect, which occurs when an electromagnetic wave radiated from an antenna is transmitted through a radome and a transmissive cover The electromagnetic-wave-transmissive module includes one or more of a radome covering the antenna and a transmissive cover, which is disposed to be spaced apart from a front side of the antenna and through which a radio wave radiated from the antenna and then transmitted through the radome is subsequently transmitted. At least one coating layer, which includes PTFE and which has a dielectric permittivity higher than the dielectric permittivity of air and lower than the dielectric permittivity of the radome and the transmissive cover, is formed on the surface of at least one of the radome and the transmissive cover.

Abstract: The present disclosure relates to a composition for a radar transmissive cover for a vehicle, which may enhance dielectric properties while excellently maintaining mechanical properties. The composition, as the composition forming the radar transmissive cover for the vehicle through which a radar beam radiated from a radar is transmitted, has a main material in which 70 to 90 wt % of Polybutylene Terephthalate (PBT) and 10 to 30 wt % of Polycarbonate (PC) are mixed and an additive containing at least reinforcing filler mixed.

Abstract: Disclosed are an electromagnetic-wave transmitting cover that transmits electromagnetic waves transmitted/received by an LF antenna and an RF antenna and an electric field generated from a capacitance touch sensor while realizing a metallic texture, and a door outer handle including the same. The electromagnetic-wave transmitting cover includes: a substrate; a primer layer formed on a surface of the substrate; and a first metal layer formed by depositing and having a plurality of first microcracks penetrating in a thickness direction.
