Abstract: A methodology for doing process control by using a heating apparatus comprising heating zones is revealed. First, a target CD (critical dimension) map is assigned. A baseline CD map corresponding to a substrate processed with the heating apparatus at a baseline setting is also obtained. An original CD map corresponding to a substrate processed at an original setting is obtained. For each heating zone, a perturbed CD map corresponding to a substrate processed at a perturbed setting is also obtained. The temperature distribution of the heating apparatus is adjusted according to the error CD map defined by the baseline CD map and the target CD map, basis functions defined by the original CD map and perturbed CD maps, and expansion coefficients expanding the error CD map with basis functions.

Abstract translation: 揭示了通过使用包括加热区域的加热装置进行过程控制的方法。 首先，分配目标CD（关键尺寸）图。 还获得了对应于在加热装置处理的基板在基线设置处的基线CD图。 获得与以原始设置处理的基板对应的原始CD图。 对于每个加热区域，也获得对应于在扰动设置处理的基板的扰动的CD图。 根据由基准CD映射和目标CD映射定义的误差CD映射，由原始CD映射和扰动CD映射定义的基函数以及扩展系数扩展错误CD映射的基础来调节加热设备的温度分布 功能。
