    摘要： This invention relates to a mask blank for use in EUV lithography and a method for its production.The mask blank comprises a substrate with a front side and a rear side whereby a coating is applied to the front side for use as a mask in EUV lithography and the rear side of the substrate comprises an electrically conductive coating. The electrically conductive coating is particularly abrasion resistant and strongly adhesive according to DIN 58196-5 (German Industry Standard), DIN 58196-4 and DIN 58196-6 and characterised by a minimum electrical conductivity. The electrically conductive coating is applied by means of ion-beam-assisted sputtering.Since the electrically conductive coating on the rear side is so abrasion resistant and strongly adhesive, the mask blank may be gripped, held and handled by means of an electrostatic holding device (chuck) without any troublesome abrasion occurring.

    摘要翻译： 本发明涉及一种用于EUV光刻的掩模板及其制造方法。 掩模坯料包括具有前侧和后侧的基板，由此在EUV光刻中将涂层施加到前侧用作掩模，并且基板的后侧包括导电涂层。 根据DIN 58196-5（德国工业标准），DIN 58196-4和DIN 58196-6，导电涂层特别耐磨，牢固，并具有最小的电导率。 通过离子束辅助溅射法施加导电涂层。 由于后侧的导电涂层具有如此耐磨性和强粘合性，所以可以通过静电保持装置（卡盘）夹持，保持和处理掩模坯料，而不会发生任何麻烦的磨损。

    摘要： A system and a method for structuring technical information in establishing a knowledge base and trouble shooting in technical equipment. An intelligent, electronical document is created in the quickiest and most efficient way for guidance training and troubleshooting of complex technical equipment. The required concepts are defined which are capable of describing states in a knowledge base, node types are defined indicating what type of information or instruction a node is to contain, views are read containing pictures or graphic descriptions of the equipment, nodes are inserted into the views to provide access points to various parts of the equipment, at least one of the nodes being a rule node containing at least one rule. The rule contains a condition part and a conclusion part, the condition part consisting of conditions on the equipment and the conclusion part containing measures to be taken if the conditions are fulfilled. The method and system are primarily used by developers and troubleshooters. The developers contribute with knowledge about technical equipment and with practical knowledge, such as rules of thumb. The troubleshooters can use the system without specific previous knowledge to perform troubleshooting, being systematically guided by the system to the source of failure.
