Abstract
In an MIM capacitor element, a leak guard that covers an upper layer electrode layer is provided between upper layer electrode layer and a reflection prevention film and, therefore, a region is not formed wherein upper layer electrode layer and reflection prevention film make a direct contact with each other. As a result, it becomes possible to completely prevent the generation of a leak current between upper layer electrode layer and reflection prevention film. Thus, an improvement in the structure of the MIM capacitor element and an improvement in a manufacturing process for the same can be achieved, thereby it becomes possible to provide a semiconductor device wherein the reliability of the MIM capacitor element can be enhanced.
