Abstract:
A semiconductor device includes a substrate divided into a memory cell region and a logic region. A split gate electrode structure is formed in a memory cell region of a substrate. A silicon oxide layer is formed on a sidewall of the split gate electrode structure and a surface of the substrate. A word line is formed on the silicon oxide layer that is positioned on the sidewall of the split gate electrode structure. The word line has an upper width and a lower width. The lower width is greater than the upper width. A logic gate pattern is formed on a logic region of the substrate. The logic gate pattern has a thickness thinner than the lower width of the word line.

Example embodiments may provide a nonvolatile memory device. The example embodiment nonvolatile memory device may include a floating gate structure formed on a semiconductor substrate with a gate insulating layer between them and/or a control gate formed adjacent to the floating gate with a tunneling insulation layer between them. The floating gate may include a first floating gate formed on the gate insulating layer, a second floating gate formed on the first floating gate with a first insulating pattern between them, and/or a gate connecting layer formed on at least one sidewall of the first insulating pattern so that the gate conducting layer may electrically connect the first floating gate and the second floating gate. The second floating gate may have a tip formed at its longitudinal end that may not contact the gate connecting layer.

Disclosed herein is an organic electroluminescent polymer having 9,9-di(fluorenyl)-2,7-fluorenyl unit and an electroluminescent device using the same. Specifically, the current invention provides an organic electroluminescent polymer having 9,9-di(fluorenyl)-2,7-fluorenyl unit, which can be used as a blue electroluminescent polymer and host material by introducing the substituted fluorenyl group at the 9-position of fluorene, and an electroluminescent device using the electroluminescent polymer. The electroluminescent polymer is applicable as a host material for highly pure blue, green and red, having high solubility, high heat stability and high quantum efficiency.
Abstract:
A method of fabricating a flash memory cell having a split gate structure. A sacrificial layer is formed on a floating gate layer formed on a semiconductor substrate. The sacrificial layer is etched to form an opening exposing a portion of the floating gate layer. A gate interlayer insulating layer pattern is formed inside the opening. After removing the sacrificial layer pattern and etching the floating gate layer (using the gate interlayer insulating layer pattern as an etch mask), a floating gate is formed under the gate interlayer insulating layer pattern. A control gate is formed overlapping a portion of the floating gate.
Abstract:
Disclosed herein is a multi-function connector for vehicles. The multi-function connector of the present invention includes a connector housing, and a plurality of terminals which are disposed in the connector housing and are connected at ends thereof to wires. The connector further includes a conductor which is coupled to at least two terminals and electrically connects the terminals to each other, and a nonconductor which surrounds the conductor. The conductor is a plate type conductor which has an elastic locking part formed by protruding and bending a part of the plate type conductor. A locking groove, having a shape corresponding to the elastic locking part, is formed in the nonconductor, so that coupling of the conductor to the nonconductor is maintained by insertion of the elastic locking part into the locking groove. Therefore, the multi-function connector of the present invention can serve as both a connector for wire connection and a connector for wire shorting, thus being used for multiple purposes. Furthermore, because the plate type conductor of the intermediate connection unit is assembled with the nonconductor by a fitting method, the structure and the manufacturing process of the connector are simplified, thus reducing the consumption of material.

Abstract:
The transmission power of a retransmission packet is controlled in the event of a packet retransmission request being sent from a receiving side in a wireless mobile communication system supporting hybrid automatic retransmission request (HARQ) transmission. In a method of controlling transmission power of retransmission packets by a mobile terminal in a wireless mobile communication system supporting hybrid automatic retransmission request (HARQ) transmission, the method includes steps of receiving, from a base station, gain information associated with the sequence of the retransmission packets; determining, using the gain information, transmission power of one of the retransmission packets; and transmitting the retransmission packet with the determined transmission power.
Abstract:
Method for configuring a transmission chain in a 3GPP2 system for supporting a flexible or variable data rate of an information bitstream in a process for mapping an information bitstream of a data rate on a physical layer, including the steps of (1) channel coding the information bitstreams with bit rates different from each other into turbo codes or convolution codes having a value inverse of 1/coding rate, and (2) repeating coded bitstream when the channel coded bitstream is smaller than a desired interleaving size, and puncturing the coded bitstream when the channel coded bitstream is greater than the desired interleaving size, for matching the channel coded bitstream to the interleaving size.
