Method and apparatus for fabrication of very large scale integration pattern features via electroless deposition on extreme ultraviolet lithography photomasks
摘要:
Embodiments disclosed herein include EUV reticles and methods of forming such reticles. In an embodiment a method of forming an EUV reticle comprises providing a reticle, where the reticle comprises, a substrate, a mirror layer over the substrate, where the mirror layer comprises a plurality of first mirror layers and second mirror layers in an alternating pattern, and a capping layer over the mirror layer. In an embodiment, the method may further comprise disposing a first layer over the capping layer, patterning an opening in the first layer, and disposing a second layer in the opening, where the second layer is disposed with an electroless deposition process.
