Abstract
A method of forming field oxides with curvilinear boundaries between active regions on a substrate in an integrated circuit (IC) so that the stresses induced in the active regions due to the formation of field oxide can be reduced. Problems like junction leakage are reduced due to the rounded boundaries of the field oxides.
