Abstract

SiOCH glasses with improved mechanical properties and ultralow dielectric constant are obtained by controlled decomposition of the porogen molecules used to create nanoscale pores, prior to the UV-hardening step. The increased Young's modulus (YM) is related to an enhanced molecular-bridging mechanism when film is hardened without porogen that is described based on percolation of rigidity theory and random network concepts.

Abstract

Atomic layer deposition (ALD) of tungsten carbide nitride (WC0.7N0.3) on low-k (dielectric constant) dielectric aromatic polymer material was investigated. Findings show that the ALD island formation on the treated polymer is not merely a function of the number of available adsorption sites but depends also on the structure and composition of the substrate surface.

Abstract

A study was conducted to investigate the thin film deposition of Ta(N) by physical vapor deposition on porous films with different average pore sizes and material compositions. The result reveals that the minimal Ta(N) thickness required to obtain a continuous metal layer on the top of the porous film depends on the porosity and pore size and on the chemical interaction of the thin film with the porous substrate.
