摘要:
A film stack includes an interlayer dielectric formed over one or more devices. The film stack further includes a first layer having a high extinction coefficient formed on the interlayer dielectric and a second layer having a low extinction coefficient formed on the first layer. The first and second layers prevent ultraviolet induced damage to the one or more devices while minimizing reflectivity for lithographic processes.
