Patent number: 7581314Abstract: A semiconductor micro-electromechanical system (MEMS) switch provided with noble metal contacts that act as an oxygen barrier to copper electrodes is described. The MEMS switch is fully integrated into a CMOS semiconductor fabrication line. The integration techniques, materials and processes are fully compatible with copper chip metallization processes and are typically, a low cost and a low temperature process (below 400° C.). The MEMS switch includes: a movable beam within a cavity, the movable beam being anchored to a wall of the cavity at one or both ends of the beam; a first electrode embedded in the movable beam; and a second electrode embedded in an wall of the cavity and facing the first electrode, wherein the first and second electrodes are respectively capped by the noble metal contact.Type: GrantFiled: February 21, 2006Date of Patent: September 1, 2009Assignee: International Business Machines CorporationInventors: Hariklia Deligianni, Panayotis Andricacos, L. Paivikki Buchwalter, John M. Cotte, Christopher Jahnes, Mahadevaiyer Krishnan, John H. Magerlein, Kenneth Stein, Richard P. Volant, James A. Tornello, Jennifer Lund

Publication number: 20060270247Abstract: Methods of forming a high dielectric constant dielectric layer are disclosed including providing a process chamber including a holder for supporting a substrate, introducing a first gas comprising a high dielectric constant (Hi-K) dielectric precursor and an oxygen (O2) oxidant into the process chamber to form a first portion of the high dielectric constant dielectric layer on the substrate, and switching from a flow of the first gas to a flow of a second gas comprising the Hi-K dielectric precursor and an ozone (O3) oxidant to form a second portion of the high dielectric constant dielectric layer on the first portion. In an alternative embodiment, another portion can be formed on the second portion using the oxygen oxidant. The invention increases throughput by at least 20% without reliability or leakage degradation and without the need for additional equipment.Type: ApplicationFiled: May 26, 2005Publication date: November 30, 2006Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Douglas Coolbaugh, Ebenezer Eshun, Kenneth Stein, Kunal Vaed
