Abstract:
Methods and apparatus for producing irradiation targets in an extreme ultraviolet (EUV) light source having an irradiation target generating system that includes a nozzle configured for ejecting droplets of a target material, and a subsystem having an electro-actuable element producing a modulation waveform to cause disturbance to the droplets thereby causing at least some of the droplets to coalesce into irradiation targets. There is included a laser producing a beam for irradiating the irradiation targets to generate an EUV-producing plasma, wherein the electro-actuable element is biased against the nozzle to enable transfer of the disturbance to the droplets while permitting relative movement between the electro-actuable element and the nozzle.
Abstract in simplified Chinese:本发明揭示用于实施一侦测器数组之系统及方法。根据某些实施例,一基板包含复数个传感组件,该复数个传感组件包括一第一组件及一第二组件以及在其间的经组态以连接该第一组件与该第二组件之一切换区。该切换区可基于回应于该等传感组件接收到具有一预定量的能量之电子而产生之信号受控制。
Abstract in simplified Chinese:本发明揭示在一多束设备中观测一样本之系统及方法。该多束设备可包括:一电子源,其经组态以产生一初级电子束;一前电流限制孔径数组,其包含复数个孔径且经组态以自该初级电子束形成复数个小束,该复数个小束中之每一者具有一相关束电流;一聚光透镜,其经组态以使该复数个小束中之每一者准直;一束限制单元,其经组态以调节该复数个小束中之每一者的该相关束电流;及一扇区磁体单元,其经组态以导向该复数个小束中之每一者以在一物镜内或至少附近形成一交叉点,该物镜经组态以将该复数个小束中之每一者聚焦至该样本之一表面上且在其上形成复数个探测光点。
Abstract in simplified Chinese:一种判定具有一材料结构之一实体系统,诸如一薄膜多层堆栈或其他光学系统的诸如光学回应之一特性之方法具有以下步骤:提供(1430)一神经网络(1440),其中该神经网络之网络架构系基于由该材料结构沿着辐射之路径进行的该辐射之散射之一模型(1420)而组态;训练(1450)及使用(1460)该神经网络以判定该实体系统之该特性。该网络架构可基于该模型借由组态参数而组态,参数包括每隐藏层之单元数目、隐藏层之数目、层互连及丢弃。
