Abstract
Chalcogenide containing semiconductor devices may be formed with a gradient film between a chalcogenide film and another film. The gradient film may have its chalcogenide concentration decrease as it extends away from the chalcogenide film, while the concentration of the other film material increases across the thickness of the gradient film moving away from the chalcogenide film.
