    Abstract: An apparatus and method for data transmission in an Orthogonal Frequency Division Multiplexing (OFDM) communication system are provided. An OFDM system includes a reference Relay Station (RS) and a cooperative relay station respectively for performing an Spatially Layered transmission Mode (SLM) process by modulating a phase and magnitude of a signal by using a predetermined modulation order suitable for the reference relay station to obtain a spatially-layered signal and for delivering the spatially-layered signal to a target Mobile Station (MS); a Base Station (BS) for selecting the reference relay station and the cooperative relay station among a plurality of relay stations; and an mobile station for detecting data through Maximum Likelihood (ML) detection in which a signal having the largest ML is detected by comparing the received spatially-layered signal with a signal which is converted through the SLM upon receiving the spatially-layered signal from the reference relay station and the cooperative relay station.

    Abstract: In a method of forming a metal-insulator-metal (MIM) capacitor in a semiconductor device, after forming a capacitor insulation layer on a lower metal layer of the MIM capacitor, an upper electrode is formed by ion implantation into the capacitor insulation layer and silicidation, without a typical reactive ion etching process. Consequently, damage to the capacitor insulation layer can be minimized, and the area of the capacitor need not increase.
