EUV Metallic Resist Performance Enhancement Via Additives - A simplified explanation of the abstract
This abstract first appeared for US patent application 18365302 titled 'EUV Metallic Resist Performance Enhancement Via Additives
Simplified Explanation
The patent application describes a method for using a photoresist layer in an extreme ultraviolet (EUV) lithography process. The photoresist layer is made up of a metallic photoresist material and one or more additives. These additives can include a solvent with a boiling point above 150 degrees Celsius, a photo acid generator, a photo base generator, a quencher, a photo de-composed base, a thermal acid generator, or a photo sensitivity cross-linker.

Original Abstract Submitted
A photoresist layer is formed over a wafer. The photoresist layer includes a metallic photoresist material and one or more additives. An extreme ultraviolet (EUV) lithography process is performed using the photoresist layer. The one or more additives include: a solvent having a boiling point greater than about 150 degrees Celsius, a photo acid generator, a photo base generator, a quencher, a photo de-composed base, a thermal acid generator, or a photo sensitivity cross-linker.
