Abstract: Provided are an apparatus and method for ensuring fairness of user datagram protocol (UDP) data transmission in an Ethernet environment. Transmission control protocol (TCP) transmission rate calculator calculates a current TCP transmission rate based on amount of a TCP data stream transmitted in real time from a transmission apparatus and received by a reception apparatus. TCP transmission rate calculator calculates the optimum transmission rate on the basis of the received amount of a TCP data stream transmitted to the reception apparatus before UDP data transmission of the transmission apparatus is started. When UDP data is transmitted from a transmission apparatus to a reception apparatus, a TCP data stream for determining fairness is transmitted together, so that the apparatus and method can be simplified by adding only the TCP stream without an additional module for estimating a queuing delay time on the basis of a round-trip time (RTT) and so on.

Abstract: Methods of forming integrated circuit devices include forming an etch stop layer on a surface of a semiconductor substrate and forming a first interlayer insulating layer on the etch stop layer. The first interlayer insulating layer is patterned to define an opening therein that exposes a first portion of the etch stop layer. This first portion of the etch stop layer is then removed to thereby expose an underlying portion of the surface of the semiconductor substrate. This removal of the etch stop layer may be performed by wet etching the first portion of the etch stop layer using a phosphoric acid solution. A semiconductor region is then selectively grown into the opening, using the exposed portion of the surface of the semiconductor substrate as an epitaxial seed layer.
