Abstract:
In one disclosed embodiment, a method for producing a high resolution resist pattern on a semiconductor wafer comprises depositing a blanket layer of material on a semiconductor wafer, forming a resist interaction substrate on the blanket layer of material, forming a resist layer of a pre-determined thickness on the resist interaction substrate, exposing the resist layer to a patterned radiation, and developing the resulting high resolution resist pattern. In one embodiment, patterned radiation is provided by an extreme ultraviolet (EUV) light source. In other embodiments, patterned radiation may be provided by an electron beam, or ion beam, for example. In one embodiment, the resist layer comprises a chemically amplified resist utilizing a photogenerated acid (PGA), and having a sublayer. In other embodiments, the resist layer includes an additive, for example, fullerite. One disclosed embodiment involves use of an ultra-thin resist layer in combination with a gold resist interaction substrate.
