Abstract: Lithography stack, intermediate semiconductor devices, and methods of fabrication are provided. The method includes obtaining an intermediate semiconductor device with a substrate, applying a spin on carbon layer over the substrate, and applying a hardmask layer over the spin on carbon layer. The intermediate semiconductor device includes a substrate, a spin on carbon layer over the substrate, and a hardmask layer over the spin on carbon layer. The lithography stack includes a spin on carbon layer, an invisible hardmask layer over the spin on carbon layer, and a photoresist layer over the invisible hardmask layer.
