Publication number: 20230050837Abstract: The present invention is directed to methods for formation of refractory carbide, nitride, and boride coatings without use of a binding agent. The present invention is directed to methods of creating refractory coatings with controlled porosity. Refractory coatings can be formed from refractory metal, metal oxide, or metal/metal oxide composite refractory coating precursor of the 9 refractory metals encompassed by groups 4-6 and periods 4-6 of the periodic table; non-metallic elements (e.g. Si & B) and their oxides (i.e. SiO2 & B2O3) are also pertinent. The conversion of the refractory coating precursor to refractory carbide, nitride or boride is achieved via carburization, nitridization, or boridization in the presence of carbon-containing (e.g. CH4), nitrogen containing (e.g. NH3), and boron-containing (e.g. B2H6) gaseous species. Any known technique of applying the refractory coating precursor can be used.Type: ApplicationFiled: August 23, 2022Publication date: February 16, 2023Applicant: THE JOHNS HOPKINS UNIVERSITYInventors: Michael BRUPBACHER, Dajie ZHANG, Dennis NAGLE

Patent number: 8452582Abstract: A method and system are provided for parametrically adapting a behavioral model pre-configured for a preset supply reference level to fluctuations therein. The behavioral model is adaptively scaled for deviation of the electronic system supply reference from its preset level. The scaling includes reconstructing a surrogate device parametrically representative of a portion of the behavioral model's undisclosed circuit. The reconstruction includes pre-setting a transistor type for the surrogate device, such that the surrogate device is configured with a conductive channel current-voltage characteristic of the preselected transistor type. Device-specific properties for the surrogate device are generated based on selective cross-correlation of operating points between the conductive channel current-voltage characteristic and V-t and I-V curves associated with the behavioral model.Type: GrantFiled: December 29, 2010Date of Patent: May 28, 2013Assignee: Cadence Design Systems, Inc.Inventors: Feras Al-Hawari, Taranjit Singh Kukal, Dennis Nagle, Raymond Komow, Jilin Tan
