    A three-dimensional numerical method for thermal analysis in X-ray lithography (1998)

    Notes: X-ray irradiation of photoresists, such as polymethylmethacrylate (PMMA), on a silicon substrate is an important technique in micro fabrication used to obtain structures and devices with a high aspect ratio. The process is composed of a mask and a photoresist deposited on a substrate (with a gap between mask and resist). Predictions of the temperature distribution in three dimensions in the different layers (mask, gap, photoresist and substrate) and of the potential temperature rise are essential for determining the effect of high flux X-ray exposure on distortions in the photoresist due to thermal expansion. In this study, we develop a numerical method for obtaining the steady state temperature profile in an X-ray irradiation process by using a preconditioned Richardson method for the Poisson equation in the micro-scale. A domain decomposition algorithm is then obtained based on the parallel "divide and conquer" procedure for tridiagonal linear systems. Numerical results show that such a method is efficient.

    Notes: X-ray lithography is an important technique in micro fabrication used to obtain structures and devices with a high aspect ratio. The X-ray exposure takes place in a system composed of a mask and a photoresist deposited on a substrate (with a gap between mask and resist). Predictions of the temperature distribution in three dimensions in the different layers (mask, gap, photoresist and substrate) and of the potential temperature rise are essential for determining the effect of high flux X-ray exposure on distortions in the photoresist due to thermal expansion. In this study, we develop a three-dimensional numerical method for obtaining the temperature profile in an X-ray irradiation process by using a hybrid finite element-finite difference scheme for solving three-dimensional parabolic equations on thin layers. A domain decomposition algorithm is then obtained based on a parallel Gaussian elimination for solving block tridiagonal linear systems. The method is illustrated by a numerical method.

    A generalized Douglas ADI method for solving three-dimensional parabolic differential equations on multilayers (1997)

    Notes: Develops a generalized Douglas ADI method for solving three-dimensional parabolic differential equations based on the idea of the regularized difference scheme. The method is simple, unconditionally stable and well suited for either simulating fast transient phenomena or for computations on fine spatial meshes. Numerical procedures that employ the generalized Douglas ADI scheme were developed to solve three-dimensional parabolic differential equations on multilayers. In these procedures, the generalized "divide and conquer" method for solving tridiagonal linear systems is applied in order to overcome the problem with the unknown value at the interface between layers. Numerical results show that the procedure is accurate and efficient.

    Effect on Mn2+ on permeability properties of frog skin (1975)
    Springer
    Pflügers Archiv 359 (1975), S. 57-67 
    Details
    ISSN: 1432-2013
    Keywords: Effect of Manganese Ion ; Frog Skin ; Transmural Potential Difference ; Short-Circuit Current ; Sodium Fluxes
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Mn2+ added to the inner bathing solution of frog skin caused a transient increase in potential difference (PD) and a decrease in total skin conductance and mannitol influx. Net Na flux and short-circuit current (Is. c.) were also reduced, the isotopic net flux being reduced more than Is. c. This observed discrepancy appears to be the result of Cl− retention in the outer medium since it was not observed when the skin was bathed in a sulfate-substituted chloridefree solution. The effect of Mn2+ on the inner side of the frog skin appears to be due to a reduced permeation of Na+ and Cl− through the outer barrier of the skin. Addition of Mn2+ to the outer solution bathing the frog skin caused an increase in PD and a smaller increase in Is. c. These changes were not associated with alterations in the fluxes of Na+ or mannitol and were observed only when chloride was present in the bathing solutions. The effect of Mn2+ on this side of the frog skin may therefore be due to a net retention of Cl− in the outer solution.

    Ultimate probability of fixation and time to fixation or loss of a gene under a variable fitness model (1974)
    Springer
    Theoretical and applied genetics 44 (1974), S. 247-254 
    Details
    ISSN: 1432-2242
    Source: Springer Online Journal Archives 1860-2000
    Topics: Biology
    Notes: Summary We investigated the time to fixation or loss and the probability of fixation of a gene under a discrete diploid model of variable fitness. Data were presented on the effects of the level of dominance, relative magnitude of the variance in fitness of the three genotypes, and selection intensity on the probability of fixation and time to absorption of a gene. The relationship of our model in the haploid case to that of Kimura and Ohta was discussed.
