    摘要: The invention provides a method of forming a phase shift mask and the resulting phase shift mask. The method forms a non-transparent film on a transparent substrate and patterns an etch stop layer on the non-transparent film. The invention patterns the non-transparent film using the etch stop layer to expose areas of the transparent substrate. Next, the invention forms a mask on the non-transparent film to protect selected areas of the transparent substrate and forms a phase shift oxide on exposed areas of the transparent substrate. Subsequently, the mask is removed and the phase shift oxide is polished down to the etch stop layer, after which the etch stop layer is removed.

    摘要: An etching process using germanium hard mask (25) includes forming a dielectric layer (15) over a major surface (11) of a semiconductor substrate (10) and depositing a metallic germanium layer (22) over the dielectric layer (15). The metallic germanium layer (22) is patterned through a photo resist (24) to form the germanium hard mask (25). The dielectric layer (15) is selectively etched through the germanium hard mask (25) to form a dielectric hard mask (35), through which the semiconductor substrate (10) is subsequently etched. After forming the dielectric hard mask (35), the germanium hard mask (25) is stripped away by oxidizing the metallic germanium hard mask (25) to transform it into a layer (27) of germanium oxide and rinsing the semiconductor substrate (10) in water to remove the germanium oxide layer (27). Preferably, the germanium hard mask (25) is removed before etching the semiconductor substrate (10).

    摘要: A trench-type storage device includes a trench in a substrate (100), with bundles of carbon nanotubes (202) lining the trench and a trench conductor (300) filling the trench. A trench dielectric (200) may be formed between the carbon nanotubes and the sidewall of the trench. The bundles of carbon nanotubes form an open cylinder structure lining the trench. The device is formed by providing a carbon nanotube catalyst structure on the substrate and patterning the trench in the substrate; the carbon nanotubes are then grown down into the trench to line the trench with the carbon nanotube bundles, after which the trench is filled with the trench conductor.

    摘要: A combined wide-image and loop-cutter pattern is provided for both cutting and forming a wide-image section to a hard mask on a substrate formed by sidewall imaging techniques in a reduced number of photolithographic steps. A single mask is formed which provides a wide mask section while additionally providing a mask to protect the critical edges of an underlying hard mask during hard mask etching. After the hard mask is cut into sections, the protective portions of the follow-on mask are removed to expose the critical edges of the underlying hard mask while maintaining shapes necessary for defining wide-image sections. Thus, the hard mask cutting, hard mask critical edge protecting, and large area mask may be formed in a reduced number of steps.
