    • A sensor of a parameter such as temperature includes an indicator encapsulated within a rigid enclosure, wherein the sensor has a characteristic that varies with the parameter that is detectable upon illumination with electromagnetic radiation through a window of the enclosure that is transparent to the radiation. In a specific example, the indicator changes an optical characteristic such as its color as a function of its temperature, and may be of an irreversible type in order to indicate the peak temperature reached. The sensor may include a pattern of such indicators that have different peak temperatures to which they respond, so that the sensor gives a unique visual pattern at each temperature within its measurement range. This pattern may be viewed directly or processed by computer to compare the pattern with those which indicate known temperatures. The sensor and system utilizing it have particular advantages for operation in a vacuum, and/or under ion bombardment, such occurs in plasma etching and deposition machines, and/or within a strong electromagnetic field, such as within the radio frequency and microwave frequency ranges. An array of such sensors positioned across a surface of a thermally conductive substrate is especially useful for measuring a temperature distribution occurring across semiconductor wafers in wafer processing machinery.
    • 诸如温度的参数的传感器包括封装在刚性外壳内的指示器,其中传感器具有随着通过对辐射透明的外壳的窗口的电磁辐射照射时可检测的参数而变化的特性。 在具体示例中,指示器将光学特性如其颜色改变为其温度的函数,并且可以是不可逆类型以便指示达到的峰值温度。 传感器可以包括这样的指示器的图案,其具有与其响应的不同峰值温度,使得传感器在其测量范围内的每个温度下给出独特的视觉图案。 该模式可以直接观看或由计算机处理,以将模式与指示已知温度的模式进行比较。 利用它的传感器和系统具有在真空中和/或离子轰击下操作的特殊优点,例如在等离子体蚀刻和沉积机器中和/或在强电磁场(例如在射频和微波频率范围内) 。 定位在导热基板的表面上的这种传感器的阵列特别适用于测量在晶片加工机械中跨半导体晶片发生的温度分布。

    • A temperature calibration substrate for producing increased temperature measurement accuracy. The temperature calibration substrate includes cavity means located below the surface of said substrate and thermocouple means disposed in the cavity for measuring the temperature of the substrate. The cavity means includes a cavity opening, an inner perimeter, and a length. Heat transfer means is disposed in the cavity means between the thermocouple means and the inner perimeter of the cavity means for transferring heat from the substrate to the thermocouple means. The cavity means is shaped to allow the thermocouple means to lay in close proximity to the substrate, and the thermocouple means is positioned substantially adjacent the inner perimeter of the cavity means and traverses the length of the cavity means thereby enhancing heat transfer efficiency from the substrate to the thermocouple means.
