Patent number: 7128559Abstract: A template for imprint lithography (IL) that reduces significantly template production costs by allowing the same template to be re-used for several technology generations. The template is composed of an array of spaced-apart moveable and individually addressable rods or plungers. Thus, the template can be configured to provide a desired pattern by programming the array of plungers such that certain of the plungers are in an “up” or actuated configuration. This arrangement of “up” and “down” plungers forms a pattern composed of protruding and recessed features which can then be impressed onto a polymer film coated substrate by applying a pressure to the template impressing the programmed configuration into the polymer film. The pattern impressed into the polymer film will be reproduced on the substrate by subsequent processing.Type: GrantFiled: January 13, 2004Date of Patent: October 31, 2006Assignee: Sandia National LaboratoriesInventors: Gregory F. Cardinale, Albert A. Talin

Publication number: 20030020104Abstract: High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. In addition, formation of a compliant substrate may include utilizing surfactant enhanced epitaxy, epitaxial growth of single crystal silicon onto single crystal oxide, and epitaxial growth of Zintl phase materials.Type: ApplicationFiled: July 25, 2001Publication date: January 30, 2003Applicant: MOTOROLA, INC.Inventors: Albert A.

Publication number: 20030017661Abstract: Semiconductor structures are provided with high quality epitaxial layers of monocrystalline materials grown over monocrystalline substrates such as large silicon wafers utilizing a compliant substrate. One way to achieve the formation of a compliant substrate includes first growing an accommodating buffer layer on a silicon wafer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and an overlying monocrystalline material layer. With laser assisted fabrication, a laser energy source is used to preclean the accommodating buffer layer, to excite the accommodating buffer layer to higher energy to promote two-dimensional growth, and to amorphize the accommodating buffer layer, without requiring transport of the semiconductor structure from one environment to another. When chemical vapor deposition is utilized, the laser radiation source can also be employed to crack volatile chemical precursors and to enable selective deposition.Type: ApplicationFiled: July 23, 2001Publication date: January 23, 2003Applicant: MOTOROLA, INC.Inventors: Ravindranath Droopad, Albert A.
