  • Publication number: 20070015082
    Abstract: A lithographic structure comprising: an organic antireflective material disposed on a substrate; and a silicon antireflective material disposed on the organic antireflective material. The silicon antireflective material comprises a crosslinked polymer with a SiOx backbone, a chromophore, and a transparent organic group that is substantially transparent to 193 nm or 157 nm radiation. In combination, the organic antireflective material and the silicon antireflective material provide an antireflective material suitable for deep ultraviolet lithography. The invention is also directed to a process of making the lithographic structure.

  • Publication number: 20060058489
    Abstract: Antireflective compositions characterized by the presence of an Si-containing polymer having pendant chromophore moieties are useful antireflective coating/hardmask compositions in lithographic processes. These compositions provide outstanding optical, mechanical and etch selectivity properties while being applicable using spin-on application techniques. The compositions are especially useful in lithographic processes used to configure underlying material layers on a substrate, especially metal or semiconductor layers.

  • Patent number: 6939664
    Abstract: Inventive silsesquioxane polymers are provided, and resist compositions that contain such silsesquioxane polymers are provided in which at least a portion of the silsesquioxane polymer contains fluorinated moieties, and at least a portion of the silisesquioxane polymer contains pendant solubility inhibiting acid-labile moieties that have low activation energy for acid-catalyzed cleaving, and the presence of high optical density moieties are minimized or avoided. The inventive polymer also contains pendant polar moieties that promote alkaline solubility of the resist in aqueous alkaline solutions. The inventive polymers are particularly useful in positive resist compositions. The invention encompasses methods of using such resist compositions in forming a patterned structure on a substrate, and particularly multilayer (e.g. bilayer) photolithographic methods, which methods are capable of producing high resolution images at wavelengths such as 193 nm and 157 nm.

A wide range of optical transmission (0.001% up to 20% at 193 nm) is obtained by this process. A post deposition process is implemented to obtain the desired properties (stability of optical properties with respect to laser irradiation and acid treatment) for use in industry. A special fabrication process for the sputter target is implemented to lower the defects of the film.
