Abstract:
A semiconductor device and a method for fabricating the same. The semiconductor device includes a substrate. At least one trench line is formed within the substrate. A pad layer is formed in contact with the at least one trench line. A seed layer is formed on and in contact with the pad layer. The seed layer has a Root Mean Square surface roughness equal to or less than 3 Angstroms. A magnetic tunnel junction stack is formed on and in contact with the seed layer. The method includes forming a seed layer on and in contact with a semiconductor structure. The seed layer is annealed and then planarized. A magnetic tunnel junction stack is formed on and in contact with the seed layer after the seed layer has been planarized.

Claim (Index 7):
The method of  claim 6 , wherein etching the magnetic tunnel junction stack layers to form the magnetic tunnel junction stack comprises:\n forming a hardmask on the magnetic tunnel junction stack layers; and etching portions of the magnetic tunnel junction stack layers not underlying the hardmask.
