Publication number: 20130076446Abstract: An amplifier circuit includes an RF transistor, a parallel resonator and a series resonator. The RF transistor has an input, an output and an intrinsic output capacitance. The parallel resonator is connected to the output of the RF transistor and includes a first inductive component connected in parallel with the intrinsic output capacitance of the RF transistor. The series resonator connects the output of the RF transistor to an output terminal and includes a second inductive component connected in series with a capacitive component. The series resonator is operable to compensate for a change in impedance of the parallel resonator over frequency.Type: ApplicationFiled: September 27, 2011Publication date: March 28, 2013Applicant: INFINEON TECHNOLOGIES NORTH AMERICAN CORP.Inventors: Richard Wilson, Saurabh Goel

Patent number: 7273638Abstract: A method of oxidizing a substrate having area of about 30,000 mm2 or more. The surface is preferably comprised of silicon-containing materials, such as silicon, silicon germanium, silicon carbide, silicon nitride, and metal suicides. A mixture of oxygen-bearing gas and diluent gas normally non-reactive to oxygen, such as Ne, Ar, Kr, Xe, and/or Rn are ionized to create a plasma having an electron density of at least about 1e12 cm?3 and containing ambient electrons having an average temperature greater than about 1 eV. The substrate surface is oxidized with energetic particles, comprising primarily atomic oxygen, created in the plasma to form an oxide film of substantially uniform thickness. The oxidation of the substrate takes place at a temperature below about 700° C., e.g., between about room temperature, 20° C., and about 500° C.Type: GrantFiled: January 7, 2003Date of Patent: September 25, 2007Assignees: International Business Machines Corp., Infineon Technologies, North American Corp.Inventors: Michael Belyansky, Oleg Glushenkov, Andreas Knorr

Patent number: 6511791Abstract: A method for exposing a workpiece in a dual exposure step-and-repeat process starts by forming a design for a reticle mask. Deconstruct the design for the reticle mask by removing a set(s) of the features that are juxtaposed to form hollow polygonally-shaped clusters with a gap in the center. Form unexposed resist on the workpiece. Load the workpiece and the reticle mask into the stepper. Expose the workpiece through the reticle mask. Reposition the workpiece by a nanostep. Then expose the workpiece through the reticle mask after the repositioning. Test whether the plural exposure process is finished. If the result of the test is NO the process loops back to repeat some of the above steps. Otherwise the process has been completed. An overlay mark is produced by plural exposures of a single mark. A dead zone is provided surrounding an array region in which printing occurs subsequent to exposure in an original exposure.Type: GrantFiled: April 28, 2000Date of Patent: January 28, 2003Assignees: International Business machines Corporation, Infineon Technologies North American Corp.Inventors: Scott J. Bukofsky, Gerhard Kunkel, Richard Wise, Alfred K. Wong
