Abstract
A system and method for using a nitrous oxide plasma treatment to eliminate defects at an interface between a stop layer and an integral layered dielectric. The system and method provide a reliable and simplified technology that eliminates the small bubble-like defects that can be common to thin nitride layers. The system includes a plasma device and a processing chamber. The method encompasses the steps of preparing a first integral layered dielectric on a substrate before depositing a stop layer thereupon. A plasma gas is then ionized. Preferably, the plasma gas is composed of nitrogen and oxygen. The stop layer is then exposed to the plasma gas until a primary surface of the stop layer is bombarded plane. A second integral layered dielectric is then formed on the primary surface. A top surface of the second integral layered dielectric is generally plane and parallel to the primary surface.
