    Abstract: The present disclosure provides a method of fabricating a semiconductor device. The method includes forming a plurality of circuit devices over a substrate. The method includes forming an organic layer over the substrate. The organic layer is formed over the plurality of circuit devices. The method includes polishing the organic layer to planarize a surface of the organic layer. The organic layer is free of being thermally treated prior to the polishing. The organic material is un-cross-linked during the polishing. The method includes depositing a LT-film over the planarized surface of the organic layer. The depositing is performed at a temperature less than about 150 degrees Celsius. The depositing is also performed without using a spin coating process. The method includes forming a patterned photoresist layer over the LT-film.

  • Publication number: 20130210232
    Abstract: A method for patterning a plurality of features in a non-rectangular pattern, such as on an integrated circuit device, includes providing a substrate including a surface with a plurality of elongated protrusions, the elongated protrusions extending in a first direction. A first layer is formed above the surface and above the plurality of elongated protrusions, and patterned with an end cutting mask. The end cutting mask includes two nearly-adjacent patterns with a sub-resolution feature positioned and configured such that when the resulting pattern on the first layer includes the two nearly adjacent patterns and a connection there between. The method further includes cutting ends of the elongated protrusions using the pattern on the first layer.

  • Publication number: 20120108040
    Abstract: A vaporizing spray deposition device for forming a thin film includes a processing chamber, a fluid line, and a spray head coupled to the fluid line proximate the processing chamber. The fluid line is configured to transfer a polymer fluid and solvent mixture to the spray head. The spray head is configured to receive the polymer fluid and solvent mixture and to atomize the polymer fluid and solvent mixture to emit it in a substantially vaporized form to be deposited on a surface and thereby forming a thin film of the polymer on the surface after evaporation of the solvent. In an embodiment, the vaporizing spray deposition device may include a heating device to perform a hard bake process on the polymer. In an embodiment, the vaporizing spray deposition device may be configured to provide a post deposition solvent spray trim process to the thin film polymer.
