Paper Title:
Preparation and Characterization of Porous Hydrogen Silsesquioxane by Sol-Gel Process
  Abstract

This paper presents study on porous Hydrogen Silsesquioxane (HSQ) of dielectric constant near 2. Porous HSQ solution was spin-on coated and then treated by wet ammonia. During the treatment, HSQ film went through a sol-gel process. Pores were uniformly formed in HSQ film after a baking process to remove solvent. A solid network structure of porous HSQ was then formed after a high-temperature curing process. In this work, we compared the properties of porous HSQ with varying process time of wet ammonia treatment and curing temperature. Change of chemical structure was analyzed by Fourier transform infrared (FTIR) spectrometry. We found that the cage structure of porous HSQ was reduced but the network structure was enhanced as treatment time of wet ammonia increased. Hardness and Young’s modulus were measured by nano-indentation technique. The adhesion strength of porous HSQ with silicon carbide was measured. Surface properties and electrical characterization of porous HSQ with varying process conditions have also been examined.
