Abstract

Methods of forming thermal oxide layers on a side wall of gate electrodes are disclosed. In particular, thermal oxide layers can be formed on a side wall of a gate electrode by forming a gate electrode on an integrated circuit substrate and forming a thermal oxide layer on a side wall of the gate electrode using a thermal oxidation process. A silicide layer can be formed on the gate electrode after the formation of the thermal oxide layer.
