Computation of Conductance and Capacitance for IC Interconnects on a General Lossy Multilayer Substrate
In this paper a simple method for analysis and modelling of transmission interconnect lines
on general lossy multilayer substrates at high bit rates is presented. The analysis is based
on semi-analytical Green's function approach and recurrence relation between the
coefficients of potential in n and n + 1 layers, respectively. The electromagnetic concept of
free charge density is applied. It allows us to obtain integral equations between electric
scalar potential and charge density distributions. These equations are solved by the
Galerkin procedure of the Method of Moments. New approach is especially adequate to
model 2-D layered structures with planar boundaries for frequencies up to 20GHz
(quasistationary field approach). The transmission line parameters (capacitance and
conductance per unit length) for the given interconnect multilayer geometry are computed.
A discussion of the calculated line admittance in terms of technological and geometrical
parameters of the structure is given. A comparison of the numerical results from the
new procedure with the techniques presented in the previous publications are provided,

Efficient procedure for capacitance matrix calculation of multilayer VLSI interconnects using quasi-static analysis and Fourier series approach, Journal of Telecommunications and Information Technology, 2002, nr 2
In this paper, we present a new approach for capacitance matrix calculation of lossy multilayer VLSI interconnects based on quasi-static analysis and Fourier projection technique. The formulation is independent from the position of the interconnect conductors and number of layers in the structure, and is especially adequate to model 2D and 3D layered structures with planar boundaries. Thanks to the quasi-static algorithms considered for the capacitance analysis and the expansions in terms of convergent Fourier series the tool is reliable and very efficient; results can be obtained with relatively little programming effort. The validity of the technique is verified by comparing its results with on-surface MEI method, moment method for total charges in the structure, and CAD-oriented equivalent-circuit methodology, respectively

Method of filling an opening in an insulation layer
The present invention is about a method for filling an opening in an insulating layer in a fast and highly reliable way and can be used to fill openings such as trenches and via holes simultaneously. This method is based on the principle of reaction enhanced wetting and simultaneous seed layer formation. The idea is, in contrast to trying to avoid the TiAl3 formation, to use this reaction to its advantage for the creation of an ultra-thin continuous Al-containing seed layer. The latter allows a bottom to top fill during the subsequent Al-containing metal deposition. As a consequence, the filling process proceeds much faster and is production worthy
