  • GaN transistor with improved bonding pad structure and method of fabricating the same
    Patent number: 9165896
    Abstract: The present invention relates to a GaN transistor, and a method of fabricating the same, in which a structure of a bonding pad is improved by forming an ohmic metal layer at edges of the bonding pad of a source, a drain, and a gate so as to be appropriate to wire-bonding or a back-side via-hole forming process. Accordingly, adhesive force between a metal layer of the bonding pad and a GaN substrate is enhanced by forming the ohmic metal at the edges of the bonding pad during manufacturing of the GaN transistor, thereby minimizing a separation phenomenon of a pad layer during the wire-bonding or back-side via-hole forming process, and improving reliability of a device.

  • Organic light-emitting device and of preparing the same
    Patent number: 9165980
    Abstract: An organic light emitting diode (OLED) and a method of manufacturing the same. An auxiliary layer comprising a high density metallic compound and an emission layer are formed by a laser induced thermal imaging (LITI) process. The LITI process reduces manufacturing costs and time by eliminating the need for a mask patterning process. The metallic compound has a density of 2 g/cm3 or greater to promote adhesion and improve interfacial planarization. This results in improved luminance uniformity (i.e. luminance mura) between pixels within an OLED display device.

  • Low-power and all-digital phase interpolator-based clock and data recovery architecture
    Patent number: 9166605
    Abstract: The proposed invention is about an improved method for serial-in and serial-out transceiver applications. The proposed system includes a dual loop phase locked loop (PLL) architecture having a PLL and a phase rotator (PR)-based delay locked loop (DLL). An advantage of this architecture is that a single PLL offers decoupled bandwidths; a wide jitter-tolerance (JTOL) bandwidth for receiving data and a narrow jitter transfer (JTRAN) bandwidth for the data transmission. Thus, the amount of jitter at the output can be substantially reduced relative to the input while offering sufficient jitter tracking bandwidth. Also, this architecture is suitable for low-power applications since a phase shifter in the data path, which is one of the most power-hungry blocks in conventional DPLL designs, is not required.
