    • The present invention relates to a method of depositing a platinum thin-film on a silicon wafer. The method includes the steps of depositing a platinum layer on an insulating oxide layer under an oxidation atmosphere to form a mixture film consisted of platinum grains, platinum oxide grains and oxygen adhered to those grains (hereinafter, "the mixture film" to be referred as "oxygen containing platinum thin-film"); depositing an additional platinum thin-film to a desired thickness on the oxygen containing platinum thin-film under a complete inert atmosphere; and annealing the silicon substrate at a temperature of 400 to 1,300.degree. C. in order to remove oxygen present in the independent form or in platinum oxide form within the oxygen containing platinum thin-film and to stabilize the entire platinum thin-film. The oxygen containing platinum thin-film layer serves as a glue layer during the depositing step of additional platinum thin-film layer and is converted into pure platinum condition after the annealing step, whereby the silicon substrate substantially does not have any glue layer between the platinum layer and the insulating layer of the silicon substrate.
    • 本发明涉及在硅晶片上沉积铂薄膜的方法。 该方法包括以下步骤:在氧化气氛下在绝缘氧化物层上沉积铂层,形成由铂颗粒,氧化铂颗粒和附着在这些晶粒上的氧构成的混合膜(以下将“混合膜”称为 “含氧铂金薄膜”); 在完全惰性气氛下在含氧铂薄膜上沉积另外的铂薄膜至所需厚度; 并在400〜1300℃的温度下退火硅衬底,以便除去含氧铂金薄膜中独立形式或氧化铂形式存在的氧并稳定整个铂薄膜。 含铂的铂薄膜层在附加的铂薄膜层的沉积步骤中用作胶层,并且在退火步骤之后转化为纯铂状态,由此硅衬底在铂之间基本上不具有任何胶层 层和硅衬底的绝缘层。

    • A data communications system and methods are disclosed. The system includes a transmitter for conveying a data signal filtered by a finite impulse response (FIR) filter to a receiver via a channel. The receiver equalizes the received data signal using a decision feedback equalizer (DFE) and the FIR. The receiver samples the data signal to determine an error signal and uses the error signal to adapt settings of a pre-cursor tap coefficient of the FIR, one or more post-cursor tap coefficients of the FIR, a phase of the recovered clock, and a coefficient of the DFE. To adapt the settings, the receiver determines the error signal based on an error sample taken from the data signal in a single clock cycle. To determine an error signal, the receiver samples the data signal at a phase estimated to correspond to a peak amplitude of a pulse response of the channel.
    • 公开了一种数据通信系统和方法。 该系统包括一个发射器,用于通过一个通道将一个由有限脉冲响应(FIR)滤波器滤波的数据信号传送到一个接收器。 接收机使用判决反馈均衡器(DFE)和FIR来均衡接收到的数据信号。 接收机采样数据信号以确定误差信号,并使用误差信号来适应FIR的前置光标抽头系数,FIR的一个或多个后置标签抽头系数,恢复时钟的相位的设置,以及 DFE的系数。 为了适应设置,接收机根据在单个时钟周期内从数据信号中获取的错误样本来确定误差信号。 为了确定误差信号,接收机以被估计为对应于信道的脉冲响应的峰值幅度的相位对数据信号进行采样。
