  • Patent number: 8435727
    Abstract: A method of reducing surface roughness of a resist feature disposed on a substrate includes generating a plasma having a plasma sheath and ions therein. A shape of the boundary between the plasma and plasma sheath is modified using a plasma sheath modifier, so that a portion of the boundary facing the substrate is not parallel to a plane defined by the substrate. During a first exposure, the resist feature is exposed to electromagnetic radiation having a desired wavelength and the ions are accelerated across the boundary having the modified shape toward the resist features over an angular range.

  • Publication number: 20120213941
    Abstract: A boundary between a plasma and a plasma sheath is controlled such that a portion of the shape is not parallel to a plane defined by a front surface of the workpiece facing the plasma. Ions in the plasma are directed toward the workpiece. These ions can either seal pores or clean a material from a structure on the workpiece. This structure may, for example, have multiple sidewalls. A process that both cleans a material and seals pores in the structure may be performed.

  • Publication number: 20120137971
    Abstract: A template used for printing is implanted to change the properties of the materials it is composed of. This template may have multiple surfaces that define indentations. The ion species that is implanted may be C, N, H, F, He, Ar, B, As, P, Ge, Ga, Si, Zn, and Al and is configured to render the implanted regions hydrophobic in one instance. This will reduce adhesion of a polymer to the template during a printing process. The implant may be at a plurality of angles so all surfaces of the template are implanted. In other instances, a film on the surface of the template is knocked in or hardened using the ion species.

  • Publication number: 20110300711
    Abstract: A method of patterning a substrate comprises providing an array of resist features defined by a first pitch and a first gap width between adjacent resist features. Particles are introduced into the array of resist features, wherein the array of resist features becomes hardened. The introduction of particles may cause a reduction in critical dimension of the resist features. Sidewalls are provided on side portions of hardened resist features. Subsequent to the formation of the sidewalls, the hardened resist features are removed, leaving an array of isolated sidewalls disposed on the substrate. The sidewall array provides a mask for double patterning of features in the substrate layers disposed below the sidewalls, wherein an array of features formed in the substrate has a second pitch equal to half that of the first pitch.
