    摘要: A capacitive sensing system with a sensor having a thin film structure. The thin film structure includes a first insulating layer and a first conductive film having a sensing electrode formed on a first surface of the first insulating layer and a second conductive film having a back guard electrode. The back guard electrode is formed in a single plane and has a peripheral portion in the same plane, and is disposed on a second surface of the first insulating layer and a first surface of a second insulating layer or protective layer. The peripheral portion of the back guard electrode extends beyond the sensing electrode to form a side guard electrode which substantially or completely surrounds the sensing electrode.

    摘要: The invention relates to a substrate for use in a lithography system, said substrate being provided with an at least partially reflective position mark comprising an array of structures, the array extending along a longitudinal direction of the mark, characterized in that said structures are arranged for varying a reflection coefficient of the mark along the longitudinal direction, wherein said reflection coefficient is determined for a predetermined wavelength. In an embodiment a specular reflection coefficient varies along the substrate, wherein high order diffractions are substantially absorbed by the substrate. A position of a beam on a substrate can thus be determined based on the intensity of its reflection in the substrate. The invention further relates to a positioning device and lithography system for cooperation with the substrate, and a method of manufacture of the substrate.
