Patent number: 8288292Abstract: A method of forming a boron nitride or boron carbon nitride dielectric produces a conformal layer without loading effect. The dielectric layer is formed by chemical vapor deposition (CVD) of a boron-containing film on a substrate, at least a portion of the deposition being conducted without plasma, and then exposing the deposited boron-containing film to a plasma. The CVD component dominates the deposition process, producing a conformal film without loading effect. The dielectric is ashable, and can be removed with a hydrogen plasma without impacting surrounding materials. The dielectric has a much lower wet etch rate compared to other front end spacer or hard mask materials such as silicon oxide or silicon nitride, and has a relatively low dielectric constant, much lower than silicon nitride.Type: GrantFiled: March 30, 2010Date of Patent: October 16, 2012Assignee: Novellus Systems, Inc.Inventors: George Andrew Antonelli, Mandyam Sriram, Vishwanathan Rangarajan, Pramod Subramonium

Patent number: 8268722Abstract: Adhesive layers residing at an interface between metal lines and dielectric diffusion barrier (or etch stop) layers are used to improve electromigration performance of interconnects. Adhesion layers are formed by depositing a precursor layer of metal-containing material (e.g., material containing Al, Ti, Ca, Mg, etc.) over an exposed copper line, and converting the precursor layer to a passivated layer (e.g., nitridized layer). For example, a substrate containing exposed copper line having exposed Cu—O bonds is contacted with trimethylaluminum to form a precursor layer having Al—O bonds and Al—C bonds on copper surface. The precursor layer is then treated to remove residual organic substituents and to form Al—N, Al—H bonds or both. The treatment can include direct plasma treatment, remote plasma treatment, UV-treatment, and thermal treatment with a gas such as NH3, H2, N2, and mixtures thereof. A dielectric diffusion barrier layer is then deposited.Type: GrantFiled: January 15, 2010Date of Patent: September 18, 2012Assignee: Novellus Systems, Inc.Inventors: Jengyi Yu, Hui-Jung Wu, Girish Dixit, Bart van Schravendijk, Pramod Subramonium, Gengwei Jiang, George Andrew Antonelli, Jennifer O'loughlin

Patent number: 8247332Abstract: Hardmask films having high hardness and low stress are provided. In some embodiments a film has a stress of between about ?600 MPa and 600 MPa and hardness of at least about 12 GPa. In some embodiments, a hardmask film is prepared by depositing multiple sub-layers of doped or undoped silicon carbide using multiple densifying plasma post-treatments in a PECVD process chamber.

Patent number: 8217724Abstract: An atomic clock comprises endohedral fullerene systems which provide the standard frequency oscillations. A magnet device applies a magnetic field to the endohedral fullerenes. The applied magnetic field is adjustable. An excitation device both excites each endohedral fullerene system to cause it to undergo transitions which generate the time-keeping oscillations, and also probes the systems such that the oscillations can be measured and the device controlled. A detection device senses the response of the systems induced by the excitation device. The output of the detection device is fed to a controller. The controller produces the atomic clock output, which is the clock signal or frequency standard, and also controls the magnet device and the excitation device.Type: GrantFiled: June 27, 2008Date of Patent: July 10, 2012Assignee: Isis Innovation LimitedInventors: George Andrew Davidson Briggs, Arzhang Ardavan

Publication number: 20110196283Abstract: Embodiments of the invention provide an architecture, system and methods for optimizing power utilization for transdermal iontophoretic drug delivery which maintain a iontophoretic driving voltage at a reduced or even minimum value to support an iontophoretic delivery current. The reduced voltage reduces the power requirements for a transdermal iontohoretic delivery system during a period of drug delivery. Embodiments of an architecture for implementing this approach can utilize a controller which compares the desired current to the actual current and adjusts the voltage to reduce the amount of power used for iontophoretic drug delivery. The controller can comprise a state machine or microprocessor. Embodiments of the invention are particularly useful for extending the battery life of transdermal iontophoretic drug delivery systems.Type: ApplicationFiled: February 9, 2011Publication date: August 11, 2011Inventors: Mir Imran, Dean P.
