Publication number: 20200185880Abstract: A first contact surface of a semiconductor laser chip can be formed to a target surface roughness selected to have a maximum peak to valley height that is substantially smaller than a barrier layer thickness. A barrier layer that includes a non-metallic, electrically-conducting compound and that has the barrier layer thickness can be applied to the first contact surface, and the semiconductor laser chip can be soldered to a carrier mounting along the first contact surface using a solder composition by heating the soldering composition to less than a threshold temperature at which dissolution of the barrier layer into the soldering composition occurs. Related systems, methods, articles of manufacture, and the like are also described.Type: ApplicationFiled: January 28, 2019Publication date: June 11, 2020Inventors: Alfred Feitisch, Gabi Neubauer, Mathias Schrempel

Publication number: 20100267013Abstract: The methods and apparatus disclosed herein concern nucleic acid sequencing by enhanced Raman spectroscopy. In certain embodiments of the invention, nucleotides are covalently attached to Raman labels before incorporation into a nucleic acid. In other embodiments, unlabeled nucleic acids are used. Exonuclease treatment of the nucleic acid results in the release of labeled or unlabeled nucleotides that are detected by Raman spectroscopy. In alternative embodiments of the invention, nucleotides released from a nucleic acid by exonuclease treatment are covalently cross-linked to nanoparticles and detected by surface enhanced Raman spectroscopy (SERS), surface enhanced resonance Raman spectroscopy (SERRS) and/or coherent anti-Stokes Raman spectroscopy (CARS). Other embodiments of the invention concern apparatus for nucleic acid sequencing.Type: ApplicationFiled: May 24, 2007Publication date: October 21, 2010Applicant: INTEL CORPORATIONInventors: Xing Su, Andrew Arthur Berlin, Selena Chan, Steven J.

Patent number: 7465578Abstract: The methods, compositions and apparatus disclosed herein are of use for nucleic acid sequence determination. The methods involve isolation of one or more nucleic acid template molecules and polymerization of a nascent complementary strand of nucleic acid, using a DNA or RNA polymerase or similar synthetic reagent. As the nascent strand is extended one nucleotide at a time, the disappearance of nucleotide precursors from solution is monitored by Raman spectroscopy or FRET. The nucleic acid sequence of the nascent strand, and the complementary sequence of the template strand, may be determined by tracking the order of incorporation of nucleotide precursors during the polymerization reaction. Certain embodiments concern apparatus comprising a reaction chamber and detection unit, of use in practicing the claimed methods. The methods, compositions and apparatus are of use in sequencing very long nucleic acid templates in a single sequencing reaction.Type: GrantFiled: July 7, 2004Date of Patent: December 16, 2008Assignee: Intel CorporationInventors: Andrew Berlin, Steven J.

Publication number: 20070105132Abstract: The methods and apparatus disclosed herein are useful for detecting nucleotides, nucleosides, and bases and for nucleic acid sequence determination. The methods involve detection of a nucleotide, nucleoside, or base using surface enhanced Raman spectroscopy (SERS). The detection can be part of a nucleic acid sequencing reaction to detect uptake of a deoxynucleotide triphosphate during a nucleic acid polymerization reaction, such as a nucleic acid sequencing reaction.
