Abstract
The present disclosure relates to a semiconductor device. The semiconductor device includes a first dielectric layer having a first region and a second region. A bottom electrode is at least partially arranged within the first region of the first dielectric layer. A memory element is over the bottom electrode and a top electrode is over the memory element. A second dielectric layer is over at least the first region of the first dielectric layer. The second dielectric layer surrounds the memory element and at least a part of the top electrode. A third dielectric layer is over the second region of the first dielectric layer and laterally adjacent to the second dielectric layer. A conductive interconnect is in the third dielectric layer and the second region of the first dielectric layer. The first dielectric layer has a different non-zero thickness within the first region than within the second region.
