The time-lag problem is treated for absorptive penetration across a heterogeneous membrane, where both the diffusivity D(x) and the partition coefficient K(x) depend on the coordinate x (0 ≦ x ≦ h), with 0 and h being the coordinates of the upstr

The monomer–dimer self-association of the dilute 3-ethyl-2-methyl-3-pentanol in tetrachloroethylene in the very dilute state was studied by infrared spectroscopy at several temperatures. The solute was deliberately chosen so that higher oligomers w

Siegel’s analysis on membrane transport in the Laplace domain [J. Phys. Chem. 95 (1991) 2556] in terms of transmission matrix, T(s), has been extended to a more useful formulation. This is achieved by combining uses of the matrix transport equation

The monomer–dimer self-association equilibrium of 2,2-dimethyl-3-ethyl-3-pentanol in n-octane has been studied by IR spectroscopy at four temperatures (288, 298, 308, and 318 K). The solute was chosen to restrict the self-association between solute

The applications of a high-transmittance embedded layer (HTEL) (T=15–35%) in an attenuated phase-shifting mask were studied by simulation with the aid of Taguchi design of experiment. A modified transmittance control mask with HTEL was proven to be

Simulations for the optimization of the mask error enhancement factor (MEEF) by using Taguchi's design of experiment (DOE) method in both dry and immersion ArF lithography have been demonstrated here. By DOE, MEEF has been successfully reduced, and t

In general, better resolution and lower mask error enhancement factor (MEEF) are obtained when a higher numerical aperture (NA) is used. However, simulations in this study show that, if Y-polarized light and off-axis illuminations were used, higher N

Because the surface roughness of a thin film will cause light scattering, the reflectance (R) and transmittance (T) measured using a UV/visible (vis) spectrometer become lower than the actual values. The deviation becomes larger with increasing rough

For 193 nm immersion lithography, it is hard to print clear 4X nm dense images (ex. contact holes) on wafer without any modifications due to lower light intensity. In the past, the most common method is to add the scattering bars, which can enhance t
