A resist composition including a polymer; and a compound represented by Formula 1,  

Resist composition

A semiconductor device is provided. The semiconductor device includes a fin type pattern, a field insulating film on a part of a sidewall of the fin-type pattern, and a gate electrode intersecting with the fin-type pattern, on the fin-type pattern and the field insulating film. The gate electrode on the field insulating film includes a first portion, a second portion, and a third portion on the field insulating film. A first width of the first portion increases as a first distance from the field insulating film, increases width of the second portion decreases as a second distance from the field insulating film increases, and a third width of the third portion increases or is substantially constant as a third distance from the field insulating film increases.

Semiconductor device

User equipment (UE) that includes a processor and that executes a random access procedure with a base station (E-UTRAN Node B (eNodeB), also known as Evolved Node B) is provided. The UE can at least temporarily be embodied by the processor. The UE may comprise: a determination unit for determining a message size that can be transmitted and that corresponds to a physical random access channel according to an assigned communication method with the base station; a calculation unit for configuring a message to correspond to the message size and for respectively calculating a preamble index and at least one message index from the message; and an encoder for providing respective encoding of the preamble index and the at least one message index, and transmitting the same to the base station.

Communication apparatus and method using random access procedure

Provided is a random access method of a node, the method including receiving spatial group information on spatial groups generated in a cell from a base station, identifying a spatial group corresponding to the node based on the spatial group information, transmitting a preamble signal to the base station by generating the preamble signal, and receiving a random access response message in response to the preamble signal.

System and method for random access based on spatial group

A photolithographic rinse solution includes deionized water, and a surfactant, the surfactant including a cyclic amine group and at least one non-amine cyclic group joined to or fused with the cyclic amine group, wherein the cyclic amine group includes a ring having a carbon number of 4 to 6, and the non-amine cyclic group includes a ring having a carbon number of 5 to 8.

Photo lithographic rinse solution and method of manufacturing a semiconductor device using the same

Disclosed is a method for transmitting integrated packet data by a relay station (RS) in a multi-hop relay communication system, including: integrating a plurality of packet data received from mobile stations (MSs) and determining a data integration scheme for transmitting the integrated data to base station (BS); receiving packet data from MSs, classifying the received packet data into one or more integration packet classes according to the determined data integration scheme, and storing the same; determining QoS (Quality of Service) requirements and a MCS (Modulation and Coding Scheme) level of the stored integration packet classes; calculating required resource according to the determined MCS level and requesting an allocation of the resource from the BS; receiving an approval for resource allocation from the BS, and modulating and coding the integrated packet class, mapping the same to the resource to configure an integrated packet; and transmitting the configured integrated packet to the BS.
