摘要:
A cleaning solution for a cured anti-reflective layer (AFC layer) component and a method of cleaning an anti-reflective layer component by using the same, wherein the cleaning solution comprises about 5–30% by weight of ammonium hydroxide, about 23–70% by weight of an organic solvent and about 10–50% by weight of water. When an organic material is spattered to adjacent equipment during implementing a coating process onto a wafer, the equipment is detached and then is dipped into the cleaning solution. Thereafter, the equipment is rinsed and dried. Cured and non-cured organic materials are advantageously removed. Cured organic materials left for a period of time, particularly anti-reflective layer components are advantageously removed.

A framing method of fixing a training signal and a control channel for multi-link (direct link and relay link) synchronization in a multi-hop relay cellular network, and a transmitting/receiving apparatus for supporting the framing method. A base station (BS) transmits BS downlink (DL) subframe sequentially including a preamble, control information, and a DL burst to a relay station (RS) or a first mobile station (MS) connected to the BS by direct link. The RS transmits an RS DL subframe sequentially including a DL burst, a postamble, and control information to a second MS connected to the BS by relay link. Therefore, difficulties of initial synchronization, handoff, and cell search can be removed from MSs. Furthermore, multi-link bursts can be located between the preamble and the postamble by Time Division Multiplexing (TDM) or Frequency Division Multiplexing (FDM).

Provided is an apparatus and method for constructing a subframe to support a multi link in a multi-hop relay cellular network. In a first section of a subframe, a subframe for communication with a mobile station (MS) is constructed, and in a next second section of the subframe, a subframe for communication with a relay station (RS) is constructed. Therefore, resources can be efficiently used without interference between subframes, pilots can be flexibly used, advanced technologies can be easily applied, and overhead due to RS switching gaps can be reduced.

Provided is an apparatus and method for constructing a frame for transmitting a direct link and a multi-hop relay link signal in one frame in a multi-hop relay cellular network. The signals are multiplexed on a time-division multiplexing basis and a base station downlink and relay station uplink subframe are located in a conventional downlink subframe. Accordingly, the overhead for a relay station receive transition gap in the downlink subframe and a relay station transmit transition gap in the conventional uplink subframe are eliminated.
