Abstract
A semiconductor structure, and a method of making the same includes a multiple electrode stacked capacitor containing a sequence of first metal layers interleaved with second metal layers. A quad-layer stack separates each of the first metal layers from each of the second metal layers, the quad-layer dielectric stack includes a first dielectric layer made of AlO, a second dielectric layer made of HfO, a third dielectric layer made of AlO, and a fourth dielectric layer made of HfO.
