Journal ArticleDOI
Exchange-biased magnetic tunnel junctions and application to nonvolatile magnetic random access memory (invited)
Stuart S. P. Parkin,Kevin P. Roche,Mahesh G. Samant,P. M. Rice,Robert Beyers,Roy Edwin Scheuerlein,Eugene J. O'Sullivan,Stephen L. Brown,J. Bucchigano,D. W. Abraham,Yu Lu,M. Rooks,Philip L. Trouilloud,R. A. Wanner,William J. Gallagher +14 more
TL;DR: In this paper, exchange biased magnetic tunnel junction (MTJ) structures are shown to have useful properties for forming magnetic memory storage elements in a novel cross-point architecture, which exhibit very large magnetoresistive (MR) values exceeding 40% at room temperature, with specific resistance values ranging down to as little as ∼60 Ω(μm)2.
Journal ArticleDOI
Spin torque switching of 20 nm magnetic tunnel junctions with perpendicular anisotropy
M. Gajek,Janusz J. Nowak,Jonathan Z. Sun,P. L. Trouilloud,Eugene J. O'Sullivan,D. W. Abraham,Michael C. Gaidis,Guohan Hu,S. Brown,Yu Zhu,R. P. Robertazzi,William J. Gallagher,Daniel C. Worledge +12 more
TL;DR: In this paper, the basic physics of spin torque switching in 20"nm diameter magnetic tunnel junctions with perpendicular magnetic anisotropy materials were demonstrated, which clearly indicates the STT MRAM device itself may be suitable for integration at much higher densities than previously proven.
Patent
Cobalt-tin alloys and their applications for devices, chip interconnections and packaging
Vlasta Brusic,Jeffrey R. Marino,Eugene J. O'Sullivan,Carlos J. Sambucetti,Alejandro G. Schrott,Cyprian E. Uzoh +5 more
TL;DR: In this article, a process for electrolessly depositing cobalt-tin alloys with adjustable tin contents from 1 to over 25 atomic percent tin is described, which is useful in the electronics and computer industries for device, chip interconnection and packaging applications.
Patent
Dual etch stop/diffusion barrier for damascene interconnects
Daniel C. Edelstein,Timothy J. Dalton,John G. Gaudiello,Mahadevaiyer Krishnan,Sandra G. Malhotra,Maurice McGlashan-Powell,Eugene J. O'Sullivan,Carlos J. Sambucetti +7 more
TL;DR: A damascene interconnect containing a dual etch stop/diffusion barrier is described in this article. But the authors do not consider the use of metal diffusion barrier in this paper.
Patent
Palladium sulfate solution for the selective seeding of the metal interconnections on polyimide dielectrics for electroless metal deposition
TL;DR: In this article, a method of selectively seeding or activating metal interconnections patterned on polyimide dielectric surfaces using an aqueous solution of palladium sulfate, palladium perchlorate or trifluoromethane sulfonate was proposed.
