Abstract

A semiconductor structure includes a bottom electrode, a magnetic tunneling junction stack over the bottom electrode, a top electrode over the magnetic tunneling junction stack, a first dielectric layer under the bottom electrode, a second dielectric layer under the first dielectric layer. The first dielectric layer has a first chemical bond energy and the second dielectric layer has a second chemical bond energy less than the first chemical bond energy.
