Abstract
A method is presented for preventing excessive cap dielectric loss in memory areas and logic areas of a device. The method includes forming a first conductive line with top via and a conductive pad over a dielectric layer, wherein the conductive pad includes a microstud, depositing a dielectric cap in direct contact with the first conductive line and the conductive pad, and constructing a top electrode, a magnetic tunnel junction (MTJ) stack, and a bottom electrode in vertical alignment with the microstud of the conductive pad.
