  • Publication number: 20180061745
    Abstract: A semiconductor chip package includes a semiconductor chip disposed over a main surface of a carrier. An encapsulation body encapsulates the chip. First electrical contact elements are electrically coupled to the chip and protrude out of the encapsulation body through a first side face of the encapsulation body. Second electrical contact elements are electrically coupled to the chip and protrude out of the encapsulation body through a second side face of the encapsulation body opposite the first side face. A first group of the first electrical contact elements and a second group of the first electrical contact elements are spaced apart by a distance D that is greater than a distance P between adjacent first electrical contact elements of the first group and between adjacent first electrical contact elements of the second group. The distances D and P are measured between center axes of electrical contact elements.

  • Publication number: 20160326048
    Abstract: The present invention relates to a glass having a surface with improved water-repellency or hydrophobicity and low reflectance, and a fabrication method thereof. A technology is employed, in which a thin film containing silicon or silicon oxide is formed on the glass surface, the nano-structures are formed by selective etching treatment using a reactive gas such as CF4 or the like to provide superhydrophobicity and low reflectance properties, and a material with low surface energy is coated onto the nano-structures. The fabrication method of the low-reflective and superhydrophobic or super water-repellent glass may execute deposition and etching processes for the glass having the superhydrophobicity and the low reflectance, and provide excellent superhydrophobicity and low reflectance to the surface of the glass which was difficult to be treated. Also, the method is sustainable due to non-use of a toxic etching solution during these processes.

  • Patent number: 9324642
    Abstract: A lead frame strip includes a plurality of connected unit lead frames, each unit lead frame having a die paddle and a plurality of leads connected to a periphery of the unit lead frame. A semiconductor die is attached to the die paddles. A molding compound covers the unit lead frames, including the semiconductor dies. Prior to testing or other processing of the lead frame strip, a gap is etched into a region of the leads which are shared by adjacent ones of the unit lead frames. The gap extends at least mostly through the shared leads. A partial cut is made in the molding compound around the periphery of the unit lead frames prior to the subsequent processing, including below the gap in the shared leads, to electrically isolate the leads of the unit lead frames.
