Method for compensating an exposure error in an exposure process

A method for compensating for an exposure error in an exposure process of a lithographic apparatus that comprises a substrate table, the method comprising: obtaining a dose measurement indicative of adose of IR radiation that reaches substrate level, wherein the dose measurement can be used to calculate an amount of IR radiation absorbed by an object in the lithographic apparatus during an exposure process; and using the dose measurement to control the exposure process so as to compensate for an exposure error associated with the IR radiation absorbed by the object during the exposure process. 一种用于补偿光刻设备的曝光过程中的曝光误差的方法，光刻设备包括衬底台，该方法包括：获得剂量测量，剂量测量指示到达衬底水平面的IR辐射的剂量，其中剂量测量能够用来计算曝光过程期间由光刻设备中的物体吸收的IR辐射的量；以及使用剂量测量来控制曝光过程以便补偿与曝光过程期间由物体吸收的IR辐射相关联的曝光误差。
