“…Fourier transform infrared (FTIR) spectroscopy.-FTIR analysis is a quantitative tool to quantify specific functional groups. 35 It correlates the intensity of the transmittance to the quantity of the functionality present in the Al surface. The wafer was analyzed between 500 cm −1 and 4000 cm −1 , as presented in Figure 15a.…”

As the feature size of integrated circuit (IC) shrinks down to 28nm and below, aluminum (Al) is considered to be one of the suitable gate materials, and cobalt (Co) is considered to be one of the suitable barrier materials. During chemical mechanical polishing (CMP) of the Al-Co gate, galvanic corrosion can occur when two kind of metals with a large open circuit potential (Eoc) difference contact with each other within the device architecture and are exposed to charge conducting CMP slurries. Al is severely corroded as an anode in the presence of Co because the standard electrode potential (E = −1.66 V) is lower than that of Co (E = −0.27 V). In this paper, using the advantages of different materials in adsorption and dissolution of different metal, the effect of glycine and TT-LYK (TT) with different concentrations on galvanic corrosion of Al and Co was studied by potentio dynamic and static polarization measurements with impedance monitoring. The potential different between Al and Co electrodes was significantly reduced for selective adsorption characteristics of the complex formed by glycine with Al and Co significantly reduced the potential difference between Al and Co electrodes. The substances formed by TT with Al and Co can be adsorbed on both surfaces well, and the current difference between Al and Co electrodes can be significantly reduced due to the difference in solubility of the reactants. When glycine and TT were used synergistically, the dynamic corrosion potential (Ecorr) difference between Al and Co electrodes was reduced to 10 mV, and the static Ecorr difference was reduced to 17 mV with glycine concentration of 1000 ppm and TT concentration of 100 ppm. The dynamic corrosion current (Icorr) difference was 0.587μA/cm2, and the static Icorr difference was 2.361μA/cm2.

“…Обычно ИК вводят в коррозионную среду в определенной концентрации, однако они могут быть использованы и для создания на поверхности металлов тонких пленок, которые впоследствии защищают металл, например, в атмосферных условиях [4], а также для повышения эффективности других средств противокоррозионной защиты, в частности, различных типов покрытий [5,6]. В качестве ИК могут использоваться индивидуальные соединения, однако более перспективно применение органических ИК в композициях с другими органическими [7][8][9] или неорганическими [10][11][12] соединениями, поскольку в этом случае возможно взаимное усиление их эффективности.…”

В настоящей работе, исследована возможность повышения коррозионной стойкости Мг90 методом послойной модификации его поверхности в растворах 13 мМ олеата натрия и 3 мМ 8-гидроксихинолина. Оценено влияние, как последовательности нанесения ингибиторов, так и толщины оксидно-гидроксидного подслоя. Показано, что покрытие 13 мМ олеата натрия // 3 мМ 8-гидрокихинолина, сформированное на воздушно-окисленном Мг90, обеспечивало наиболее эффективную защиту металла от коррозии, чем их индивидуальные слои. Увеличение толщины оксидного подслоя не способствовало повышению защитного действия полислойных покрытий, однако существенно повышало коррозионную стойкость Мг90 с пленками индивидуальных ингибиторов.
