Method of line roughness improvement by plasma selective deposition

A substrate is provided with a patterned layer, for example, a photo resist layer, which may exhibit line roughness. In one exemplary embodiment, the patterned layer may be an extreme ultraviolet (EUV) photo resist layer. In one method, selective deposition of additional material is provided on the EUV photo resist layer after patterning to provide improved roughness and lithographic structure height to allow for more process margin when transferring the pattern to a layer underlying the photo resist. The additional material is deposited selectively thicker in areas above the photo resist than in areas where the photo resist is not present, such as exposed areas between the photo resist pattern. Pattern transfer to a layer underlying the photo resist may then occur (for example via an etch) while the patterned photo resist and additional material above the photo resist may collectively operate as an etch mask.

Semiconductor Device and Method of Coating a Semiconductor Wafer with High Viscosity Liquid Photoresist Using N2 Purge

A semiconductor manufacturing device has an outer cup and inner cup with a wafer suction mount disposed within the outer cup. A photoresist material is applied to a first surface of a semiconductor wafer disposed on the wafer suction mount while rotating at a first speed. A gas port is disposed on the inner cup for dispensing a gas oriented toward a bottom side of the semiconductor wafer. The gas port purges a second surface of the semiconductor wafer with a gas to remove contamination. The second surface of the semiconductor wafer is rinsed while purging with the gas. The gas can be a stable or inert gas, such as nitrogen. The contamination is removed from the second surface of the semiconductor wafer through an outlet between the inner cup and outer cup. The semiconductor wafer rotates at a second greater speed after discontinuing purge with the gas.

Hydrogen gas sensors based on nanoparticle-decorated, patterned carbon nanotube ropes

Nanoparticle(NP)-decorated carbon nanotube (CNT) ropes used as sensing elements for hydrogen gas (H.sub.2) chemiresistors are described herein. The NP-decorated CNT rope sensors were prepared by dielectrophoretic deposition of a single semiconducting CNT rope followed by the electrodeposition of metal nanoparticles to highly disperse said nanoparticles on the CNT surfaces. The rope sensors produced a relative resistance change 20-30 times larger than what was observed at single, pure Pd nanowires. Thus, the rope sensors improved upon all H.sub.2 sensing metrics (speed, dynamic range, and limit-of-detection) relative to single Pd nanowires.
