    Metal-Insulator-Metal capacitors with ALD grown SrTiO3: Influence of Pt electrodes

    IOP Conference Series: Materials Science and Engineering, vol. 41

    2012

    Abstract anzeigen

    Metal-Insulator-metal (MIM) capacitors with atomic layer deposited (ALD) single SrTiO3 dielectric have been investigated in this work. Structural and electrical properties were studied after the formation of the MIM stack consisting of the platinum (Pt) bottom electrode, 50 nm SrTiO3 layer and the top Pt electrode. The as deposited films were amorphous and had a dielectric constant of ~ 10, whereas the annealing of the samples in the nitrogen (N2) or oxygen (O2) atmosphere at 550-600 °C led to the crystallization of the SrTiO3 and therefore to the increased dielectric constant of ~ 85. In addition, the electrical results revealed that the combination of SrTiO3 with the high work function electrode like Pt, provided better leakage current performance in comparison with TiN/ SrTiO3 stacks. The values as low as ~ 10−7 A/cm2 at 2 V were observed for both in N2 or O2 annealed SrTiO3 layers. On the other hand, the samples annealed in O2 atmosphere at 600 °C possessed lower capacitance-voltage nonlinearity coefficients (−645 ppm/V2) than the ones for N2 annealed samples (-2700 ppm/V2).

    Properties of atomic-vapor and atomic-layer deposited Sr, Ti, and Nb doped Ta2O5 Metal–Insulator–Metal capacitors

    Thin Solid Films, vol. 520, no. 14, pp. 4576-4579

    2012

    DOI: 10.1016/j.tsf.2011.10.199

    Abstract anzeigen

    Atomic Vapor Deposition and Atomic Layer Deposition techniques were applied for the depositions of Ta2O5, Ti–Ta–O, Sr–Ta–O and Nb–Ta–O oxide films for Metal–Insulator–Metal (MIM) capacitors used in back-end of line for Radio Frequency applications. Structural and electrical properties were studied. Films, deposited on the TiN bottom electrodes, in the temperature range of 225–400 °C, were amorphous, whereas the post deposition annealing at 600 °C resulted in the crystallization of Nb–Ta–O films. Electrical properties of MIM structures, investigated after sputtering Au top electrodes, revealed that the main characteristics were different for each oxide. On one hand, Ti–Ta–O based MIM capacitors possessed the highest dielectric constant (50), but the leakages currents were also the highest (~ 10− 5 A/cm2 at − 2 V). On the other hand, Sr–Ta–O showed the lowest leakage current densities (~ 10− 9 A/cm2 at − 2 V) as well as the smallest capacitance–voltage nonlinearity coefficients (40 ppm/V2), but the dielectric constant was the smallest (20). The highest nonlinearity coefficients (290 ppm/V2) were observed for Nb–Ta–O based MIM capacitors, although relatively high dielectric constant (40) and low leakage currents (~ 10− 7 A/cm2 at − 2 V) were measured. Temperature dependent leakage-voltage measurements revealed that only Sr–Ta–O showed no dependence of leakage current as a function of the measurement temperature.

    Plasma enhanced atomic layer batch processing of aluminum doped titanium dioxide

    Journal of Vacuum Science & Technology A, vol. 30, no. 1

    2012

    DOI: 10.1116/1.3670876

    Abstract anzeigen

    Among many promising high-k dielectrics, TiO2 is an interesting candidate because of its relatively high k value of over 40 and its easy integration into existing semiconductor manufacturing schemes. The most critical issues of TiO2 are its low electrical stability and its high leakage current density. However, doping TiO2 with Al has shown to yield significant improvement of layer quality on Ru electrodes [S. K. Kim et al., Adv. Mater. 20, 1429 (2008)]. In this work we investigated if atomic layer deposition (ALD) of Al doped TiO2 is feasible in a batch system. Electrical characterizations were done using common electrode materials like TiN, TaN, or W. Additionally, the effect of plasma enhanced processing in this reactor was studied. For this investigation a production batch ALD furnace has been retrofitted with a plasma source which can be used for post deposition anneals with oxygen radicals as well as for directly plasma enhanced ALD. After evaluation of several Ti precursors a deposition process for AlTiOx with excellent film thickness and composition uniformity was developed. The effects of post deposition anneals, Al2O3 interlayers between electrode and TiO2, Al doping concentration, plasma enhanced deposition and electrode material type on leakage current density are shown. An optimized AlTiOx deposition process on TaN electrodes yields to leakage current density of 5 × 10−7 A/cm2 at 2 V and k values of about 35. Thus, it could be demonstrated that a plasma enhanced batch ALD process for Al doped TiO2 is feasible with acceptable leakage current density on a standard electrode material.

    A calculation methodology proposed for liquid droplet impingement erosion

    Nuclear Engineering and Design, vol. 242, pp. 157-163

    2012

    DOI: 10.1016/j.nucengdes.2011.10.004

    Abstract anzeigen

    Bent pipe wall thinning has been often found at the elbow of the drain line and the high-pressure secondary feed-water bent pipe in nuclear reactors. Liquid droplet impingement (LDI) erosion could be regarded as one of the major causes and is a significant issue of the thermal hydraulics and structural integrity in aging and life extension for nuclear power plant safety. In this paper a computational methodology is established for simulation of LDI erosion using computational fluid dynamics (CFD) simulation and theoretical calculation. Two-phase flow numerical simulations are conducted for standard elbow geometry, typically with the pipe diameter of 170 mm. This computational fluid model is built up by incompressible Reynolds Averaged Navier–Stoke equations using standard k–ɛ turbulence model and the SIMPLE algorithm, and the numerical droplet model adopts the Lagrangian approach. The turbulence damping in vapor–droplets flow is theoretically analyzed by a damping function on the energy spectrum basis of single phase flow. Locally, a droplet impact angle function is employed to determine the overall erosion rate. Finally, the overall and local investigations are combined to purpose a general methodology of LDI erosion prediction procedure, which has been complemented into CFD code. Based on our more physical computational results, comparison with an available accident data was made to prove that our methodology could be an appropriate way to simulate and predict the bent pipe wall thinning phenomena.

    Re-examining the differential familial liability of agoraphobia and panic disorder

    Depression and Anxiety, vol. 29, no. 11, pp. 931-938

    2012

    DOI: 10.1002/da.21975

    Abstract anzeigen

    BACKGROUND: Controversy surrounds the question of whether agoraphobia (AG) exists as an independent diagnostic entity apart from panic. In favor of this position, AG without panic disorder (PD) in parents was found being unrelated to offsprings' risk for AG or PD, albeit it may enhance the familial transmission of PD (Nocon et al., Depress Anxiety 2008;25:422-434). However, a recent behavioral genetic analysis (Mosing et al., Depress Anxiety 2009;26:1004-1011) found an increased risk for both PD and AG in siblings of those with AG without PD, casting doubt on whether AG exists independently of PD. Convincing evidence for either position notably requires considering also other anxiety disorders to establish the position of AG relative to the panic/anxiety spectrum. METHODS: Familial transmission of panic attacks (PAs), PD, and AG was examined in a 10-year prospective-longitudinal community study of 3,021 adolescents and young adults including completed direct and indirect information on parental psychopathology. Standardized diagnostic assessments using the Munich-Composite International Diagnostic Interview allowed generating exclusive diagnostic groups independent from diagnostic hierarchy rules. RESULTS: Parental PD without AG was associated with an increased risk for PA and PD+AG, but not for PD without AG or AG without PD in offspring. Parental AG without PD was unrelated to the offsprings' risk for PA, exclusive PD or AG, or PD+AG. Findings were largely unaffected by adjustment for other offspring or parental anxiety disorders. CONCLUSIONS: Findings provide further evidence for the independence of AG apart from the PD spectrum.
