Abstract
In one embodiment, the present invention provides a method of treating a dielectric layer 24. First, the dielectric layer is heated while being subjected to an O.sub.2 plasma. After that, the dielectric layer is heated while being subject to an ozone environment. This method can be useful in forming a capacitor 12 dielectric 24. In turn, the capacitor could be used in a DRAM memory device.
