    • An through-substrate via fabrication method requires forming a through-substrate via hole in a semiconductor substrate, depositing an electrically insulating, continuous and substantially conformal isolation material onto the substrate and interior walls of the via using ALD, and depositing a conductive material into the via and over the isolation material using ALD such that it is electrically continuous across the length of the via hole. The isolation material may be prepared by activating it with a seed layer deposited by ALD. The via hole is preferably formed by dry etching first and second cavities having respective diameters into the substrate's top and bottom surfaces, respectively, to form a single continuous aperture through the substrate. The present method may be practiced at temperatures of less than 200° C. The basic fabrication method may be extended to provide vias with multiple conductive layers, such as coaxial and triaxial vias.
    • 通过基板通孔的制造方法需要在半导体基板中形成贯通基板通孔,使用ALD将电绝缘的,连续的和基本上共形的隔离材料沉积在基板和通孔的内壁上,并将导电材料沉积到 通过和使用ALD的隔离材料,使得其在通孔的长度上是电连续的。 隔离材料可以通过用由ALD沉积的种子层激活来制备。 通孔优选通过将具有各自直径的第一和第二空腔分别干蚀刻到基板的顶部和底部表面中,以形成通过基板的单个连续孔而形成。 本方法可以在小于200℃的温度下实施。可以扩展基本制造方法以提供具有多个导电层的通孔,例如同轴和三轴通孔。

    • A deformable mirror formed out of two layers of a nanolaminate foil attached to a stiff substrate is introduced. Deformation is provided by an electrostatic force between two of the layers. The internal stiffness of the structure allows for high-spatial-frequency shapes. The nanolaminate foil of the present invention allows for a high-quality mirror surface. The device achieves high precision in the vertical direction by using foils with accurately controlled thicknesses, but does not require high precision in the lateral dimensions, allowing such mirrors to be fabricated using crude lithography techniques. Such techniques allow structures up to about the meter scale to be fabricated.
