Utilizing sidewall spacer features to form magnetic tunnel junctions in an integrated circuit

Novel methods for reliably and reproducibly forming magnetic tunnel junctions in integrated circuits are described. In accordance with aspects of the invention, sidewall spacer features are utilized during the processing of the film stack. Advantageously, these sidewall spacer features create a tapered masking feature which helps to avoid byproduct redeposition during the etching of the MTJ film stack, thereby improving process yield. Moreover, the sidewall spacer features may be used as encapsulating layers during subsequent processing steps and as vertical contacts to higher levels of metallization.
