Abstract: An image sensor for immersion lithography, the image sensor including: a grating; an absorber layer on the grating, the absorber layer configured to absorb radiation; and a liquidphobic coating at an upper surface of the image sensor, wherein a protective layer is provided between the absorber layer and the liquidphobic layer, the protective layer being less reactive than the absorber layer to an immersion liquid.
