Minimally spaced MRAM structures

摘要

A method of forming minimally spaced apart MRAM structures is disclosed. A photolithography technique is employed to define patterns an integrated circuit, the width of which is further reduced by etching to allow formation of patterns used to etch digit line regions with optimum critical dimension between any of the two digit line regions. Subsequent pinned and sense layers of MRAM structures are formed over the minimally spaced digit regions.
