MRAM DEVICE STRUCTURES AND METHODS OF FABRICATING THE SAME - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240099149 titled 'MRAM DEVICE STRUCTURES AND METHODS OF FABRICATING THE SAME
Simplified Explanation
The abstract describes a method for forming a semiconductor structure with a magnetic tunneling junction (MTJ) and a conductive capping layer. The method involves depositing dielectric layers, planarization processes, patterning the dielectric layer to expose the capping layer, removing the capping layer, depositing an electrode layer, and performing a second planarization process to make the surfaces coplanar.
