Lithographic apparatus comprising an object with an upper layer having improved resistance to peeling off

A lithographic apparatus has an object, the object includes: a substrate and optionally a lower layer on the substrate; an upper layer; and an intermediate layer between the upper layer and the substrate, wherein a bond strength between the intermediate layer and the substrate or lower layer is grea...

Zusammenfassung:A lithographic apparatus has an object, the object includes: a substrate and optionally a lower layer on the substrate; an upper layer; and an intermediate layer between the upper layer and the substrate, wherein a bond strength between the intermediate layer and the substrate or lower layer is greater than a bond strength between the intermediate layer and the upper layer and the intermediate layer has a Young's Modulus and/or a Poisson ratio within 20% of that of the upper layer.
