Abstract
A method of forming a contact opening between two conductive features over a semiconductor substrate. Oxide spacers are formed adjacent to the conductive features. A doped oxide layer is then deposited over the semiconductor substrate. Finally, the contact opening is etched through the doped oxide layer between the conductive features such that the oxide spacers are exposed within the contact opening.
