    • A lithographic apparatus capable of wirelessly communicating control and power signals, is presented herein. In one embodiment, the apparatus comprises an illumination system to provide a beam of radiation, a support structure configured to support a patterning device that imparts the beam of radiation with a pattern in its cross-section, a substrate holder configured to hold a substrate, a projection system to project the patterned beam radiation onto a target portion of the substrate, and a wireless signaling system configured to transmit and receive information-bearing electromagnetic radiation. The wireless system comprises at least a transmitter to transmit the electromagnetic radiation and a first transducer configured to receive and convert the electromagnetic radiation into a first electrical signal containing the information which is used to control at least a portion of the support structure, the substrate table, the projection system, and the illumination system.
    • 本文提供了能够无线地传送控制和功率信号的光刻设备。 在一个实施例中,该装置包括用于提供辐射束的照明系统,被配置为支撑图案形成装置的支撑结构,所述图案形成装置以其横截面中的图案赋予辐射束;衬底保持器,其构造成保持衬底, 投影系统,用于将图案化的束辐射投影到基板的目标部分上;以及无线信号系统,被配置为发送和接收带信息的电磁辐射。 所述无线系统至少包括用于传输电磁辐射的发射器和被配置为接收并将电磁辐射转换成包含用于控制支撑结构的至少一部分的信息的第一电信号的第一换能器,所述衬底台 ,投影系统和照明系统。
