Patent number: 10033152Abstract: An antireflective structure and a fabrication method thereof are disclosed. In one aspect, the antireflective structure includes a substrate, a buffer layer on the substrate, and an anticorrosion layer on the buffer layer, wherein the corrosion resistant layer comprises a densely packed cubic lattice structure. In one aspect, the fabrication method includes depositing a first buffer layer on a substrate in an e-beam deposition process, and depositing a first anticorrosion layer on the first buffer layer in an e-beam deposition process, wherein the substrate comprises sapphire, the first corrosion resistant layer comprises lutetia, and the first buffer layer comprise silicon carbide.Type: GrantFiled: September 10, 2015Date of Patent: July 24, 2018Assignee: RADIATION MONITORING DEVICES, INC.Inventors: Vivek V. Nagarkar, Zsolt Marton, Harish B. Bhandari

Publication number: 20170012001Abstract: An interconnect structure for integrated circuits for copper wires in integrated circuits and methods for making the same are provided. Mn, Cr, or V containing layer forms a barrier against copper diffusing out of the wires, thereby protecting the insulator from premature breakdown, and protecting transistors from degradation by copper. The Mn, Cr, or V containing layer also promotes strong adhesion between copper and insulators, thus preserving the mechanical integrity of the devices during manufacture and use, as well as protecting against failure by electromigration of the copper during use of the devices and protecting the copper from corrosion by oxygen or water from its surroundings. In forming such integrated circuits, certain embodiments of the invention provide methods to selectively deposit Mn, Cr, V, or Co on the copper surfaces while reducing or even preventing deposition of Mn, Cr, V, or Co on insulator surfaces.Type: ApplicationFiled: July 11, 2016Publication date: January 12, 2017Inventors: Roy Gerald GORDON, Harish B. BHANDARI, Yeung AU, Youbo LIN
