Patent number: 8409768Abstract: Growing spin-capable multi-walled carbon nanotube (MWCNT) forests in a repeatable fashion will become possible through understanding the critical factors affecting the forest growth. Here we show that the spinning capability depends on the alignment of adjacent MWCNTs in the forest which in turn results from the synergistic combination of a high areal density of MWCNTs and short distance between the MWCNTs. This can be realized by starting with both the proper Fe nanoparticle size and density which strongly depend on the sheet resistance of the catalyst film. Simple measurement of the sheet resistance can allow one to reliably predict the growth of spin-capable forests. The properties of pulled MWCNTs sheets reflect that there is a relationship between their electrical resistance and optical transmittance. Overlaying either 3, 5, or 10 sheets pulled out from a single forest produces much more repeatable characteristics.Type: GrantFiled: October 12, 2010Date of Patent: April 2, 2013Assignee: Board of Regents, The University of Texas SystemsInventors: Jae Hak Kim, Gil Sik Lee, Kyung Hwan Lee, Lawrence J.

Publication number: 20130032846Abstract: A eutectic metal layer (e.g., gold/tin) bonds a carrier wafer structure to a device wafer structure. In one example, the device wafer structure includes a silicon substrate upon which an epitaxial LED structure is disposed. A layer of silver is disposed on the epitaxial LED structure. The carrier wafer structure includes a conductive silicon substrate covered with an adhesion layer. A layer of non-reactive barrier metal (e.g., titanium) is provided between the silver layer and the eutectic metal to prevent metal from the eutectic layer (e.g., tin) from diffusing into the silver during wafer bonding. During wafer bonding, the wafer structures are pressed together and maintained at more than 280° C. for more than one minute. Use of the non-reactive barrier metal layer allows the total amount of expensive platinum used in the manufacture of a vertical blue LED manufactured on silicon to be reduced, thereby reducing LED manufacturing cost.Type: ApplicationFiled: August 2, 2011Publication date: February 7, 2013Applicant: Bridgelux, Inc.Inventor: Chao-Kun Lin

Publication number: 20130034947Abstract: Embodiments of the invention generally relate to nonvolatile memory devices and methods for manufacturing such memory devices. The methods for forming improved memory devices, such as a ReRAM cells, provide optimized, atomic layer deposition (ALD) processes for forming a metal oxide film stack which contains at least one hard metal oxide film (e.g., metal is completely oxidized or substantially oxidized) and at least one soft metal oxide film (e.g., metal is less oxidized than hard metal oxide). The soft metal oxide film is less electrically resistive than the hard metal oxide film since the soft metal oxide film is less oxidized or more metallic than the hard metal oxide film. In one example, the hard metal oxide film is formed by an ALD process utilizing ozone as the oxidizing agent while the soft metal oxide film is formed by another ALD process utilizing water vapor as the oxidizing agent.Type: ApplicationFiled: August 5, 2011Publication date: February 7, 2013Applicant: INTERMOLECULAR, INC.Inventors: Zhendong Hong, Hieu Pham, Randall Higuchi, Vidyut Gopal, Imran Hashim
