Investigation of Low-Dielectric constant Hydrogen Silsesqnioxane as Intermetal Dielectric

Abstract
As ULSI circuits are scaled down to deep submicron regime, interconnect delay becomes increasingly dominant over intrinsic gate delay. To reduce the RC delay time, many low dielectric constant materials have been developed.
One of the most promising low-k materials is siloxane-based hydrogen silsesquioxane (HSQ) having the general formula (HSiO3/2)2n, n=2, 3, etc. available as Flowable Oxide (FOx). But low mechanical strength is the problem of HSQ. In order to modify the material composition and mechanical intensity of HSQ, a novel siloxane-based inorganic spin-on material Modified-HSQ has been developed for intermetal dielectric applications.
In this thesis, the Intrinsic Properties of M-HSQ was investigated. And the effect of H2, O2 plasma treatment was investigated. Besides, In order to avoid the damage when remove the PR, to achieve small linewidth and reduce linewidth fluctuations. We employed E-Beam lithography to pattern the M-HSQ film. The leakage current of M-HSQ film by E-Beam curing is lower than film by conventional process.
