“…The significance of the isotherm in studies of adsorption was pointed out long ago, and for this reason many studies have been made in this field. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] The main effort concerns adsorption isotherms of neutral organic adsorbates, whereas considerably little is the work on ionic isotherms of specific adsorption on electrode surfaces. The work on the latter subject starts with the attempts of Levine, Bockris, and their colleagues to model the inner layer in the presence of specifically adsorbed ions.2-9 A complete review of these models is given in ref 5.…”

A new approach, which combines classical thermodynamics with basic electrostatic arguments, is proposed for the development of new ionic isotherms of specific adsorption on ideally polarized electrode surfaces. The main features of this approach are the following. The inner layer is considered to consist of two zones, along which the electric field is homogeneous. Then the Gauss theorem of electrostatics is used to correlate the potential drop across the inner layer with the electrode charge density. This correlation allows the derivation of the electrochemical potentials of the constituents of the inner layer based exclusively on the properties of certain thermodynamic functions of this layer. The adsorption isotherms, which arise from the electrochemical potentials, can take into account changes in the dielectric constant, the inner layer thickness, and the orientation of the solvent dipoles during the adsorption process. Comparison with experiment shows that even the simplest isotherm, which takes into account only variations of the dielectric constant, can give an almost quantitative description of experimental isotherms.

“…Although remarkable efforts have been made by Damaskin and co-workers (8)(9)(10)(11)(12) on the development of adsorption isotherms for organic cations, information resulting from non-ionic isotherms, though it will be criticized, may help our understanding on the adsorption behaviour of these substances.…”

“…We derive the superfilling phenomenon in terms of co-adsorption kinetics which is based on the fundamental work of Frumkin and Damaskin. [14][15][16] They investigated that the presence of a second additive species leads to completely different adsorption behaviors than in z E-mail: romy.liske@ipms.fraunhofer.de the case of a single additive. The adsorption can either be enhanced or suppressed by the presence of another additive species (Figure 1).…”

The proceeding scaling in microelectronic devices requires smaller and smaller copper wires for energy transfer in integrated devices. Voids in the copper wires lead to a resistance increase and damage of the wiring. Copper wires are fabricated by electrochemical deposition as it enables a bottom-up, void free copper growth, so-called superfilling. The present work focuses on the mechanism of the electrochemical deposition with the goal of understanding and describing the superfilling. Electrochemical measurements and partial fill experiments under production-like conditions are carried out to study the effects of bath additives. The co-adsorption theory is adopted to explain additive interaction which is presumed to be the key for superfilling. It is shown that superfilling is a result of the synergetic adsorption behavior of at least two organic additives and a kinetic balancing between additive accumulation and copper deposition rate.
