Abstract: A method of forming a semiconductor structure includes forming a first top electrode (TE) layer over a magnetic tunnel junction (MTJ) layer and performing a smoothing treatment on the first TE layer. The smoothing treatment is performed in situ after the forming first TE layer. The smoothing treatment removes spike point defects from the first TE layer. Additional TE layers may be formed over the first TE layer.
