摘要
Mesoporous silica films prepared through surfactant-templating process is one of promising candidates as low-dielectric-constant (k) materials, which is important in the future IC industry. In this paper, the difference of surface morphology and that of electrical properties of mesoporous silica films prepared with different templates are reported. It is suggested that tween is a superior surfactant and a template for making porous silica low k films. © 2003 Elsevier Science B.V. All rights reserved.
