Abstract: Large grain metal bitlines are formed above magnetic tunnel junction pillars used as MRAM bits without materially affecting the magnetic properties of the magnetic tunnel junctions. A copper or copper alloy bitline having relatively small grains is formed over the pillars. Laser annealing is employed to melt the bitline. Subsequent cooling and recrystallization results in a reduction of the number of grain boundaries in the bitline and a reduction in bitline effective resistivity. Multiple melt/cool cycles may be used. Bitline grains are vertically aligned with the pillars in a resulting structure.

Abstract: A harden gap fill dielectric material that has improved chemical and physical properties is formed laterally adjacent to a multilayered magnetic tunnel junction (MTJ) pillar and a top electrode structure of a memory structure. The harden gap fill dielectric material can be formed by introducing, via ion implantation, a bond breaking additive into an as deposited gap fill dielectric material layer and thereafter curing the gap fill dielectric material layer containing the bond breaking additive. The curing includes UV curing alone, or UV curing in combination with laser annealing. The curing employed in the present application does not negatively impact the MTJ pillar or top electrode structure.

Abstract: Embodiments of the invention include a method of forming a multi-layer integrated circuit (IC) structure that includes forming a passive energy source formed from a conductive metal. A dielectric target layer is formed over the first energy source. An active energy source is used to generate electromagnetic radiation having a predetermined wavelength, wherein the dielectric target layer is substantially transparent to the electromagnetic radiation at the predetermined wavelength. The dielectric target layer is exposed to the electromagnetic radiation by transmitting the electromagnetic radiation into and through the dielectric target layer to impact the passive energy source. The passive energy source is configured to, based at least in part on being exposed to the electromagnetic radiation, absorb the electromagnetic radiation, experience a conductive material temperature increase such that the conductive material generates heat energy, and emit the generated heat energy to the dielectric target layer.

Abstract: Methods for post-lithographic inspection using an e-beam inspection tool of organic extreme ultraviolet sensitive (EUV) sensitive photoresists generally includes conformal deposition of a removable metal carboxide or metal carboxynitride onto the relief image. The conformal deposition of the metal carboxide or metal carboxynitride includes a low temperature vapor deposition process of less than about 100° C. to provide a coating thickness of less than about 5 nanometers. Subsequent to e-beam inspection, the metal carboxide or metal carboxynitride coating is removed using a wet stripping process. Once stripped, the wafer can continue on to further process fabrication without being a sacrificial wafer.

Abstract: A lithographic patterning method includes forming a multi-layer patterning material film stack on a semiconductor substrate. Forming the patterning material film stack includes forming a hard mask layer and forming a resist layer over the hard mask layer. The hard mask layer is formed such that an interface portion of the hard mask layer proximate the resist layer has a higher metal content than other portions of the hard mask layer. The method further includes exposing the patterning material film stack to patterning radiation to form a desired pattern in the resist layer, developing the pattern formed in the resist layer, etching the hard mask layer in accordance with the developed pattern, and removing remaining portions of the resist layer. The hard mask layer illustratively includes metal oxide, metal nitride and/or metal oxynitride, and may exhibit an elevated surface hydrophobicity due to its high metal content interface portion.
