摘要
We evaluated elastic modulus of various porous and nonporous inorganic low-k films by means of a nano-indentation...Elastic modulus of various low-k films shows a linear dependence on the film density for porous and nonporous inorganic low-k materials, respectively. We have studied the effect of pore aggregation on elastic modulus of thin films by a finite element method (FEM) using the 2-dimensional random pore generation model. FEM Results of elastic modulus, which were calculated for 2-dimensional random pore model, extremely well fit with the experimental data obtained by a nano-indentation method.
