    摘要: The present invention relates to the activation of a software upgrade in a lithographic apparatus that transfers a pattern onto a substrate. The time and date of the activation of a software upgrade is compared with the time and date of the exposure of the first layer of a substrate or of a “lot” of substrates. If the activation date and time is later than the first exposure date and time, software-functionality types is not mixed on a single lot or substrate and the old software-functionality is used for that lot or substrate. If, on the other hand, the activation date and time of the software-functionality update is earlier than the first exposure of the lot or substrate, the lot or substrate has not yet been affected by the old software-functionality and the new, updated software-functionality may be used to control the pattern transfer onto all of the substrate layers.
