Patent ID: 7015059

Claim:
A manufacturing method for a thin film magnetic memory device, comprising the steps of: depositing a conductor film on a main surface of a semiconductor substrate; depositing a lamination film, including a magnetic film, on said conductor film; forming a first mask film on said lamination film; etching a portion of said lamination film and a portion of said conductor film using said first mask film as a mask while leaving the other portions, thereby forming first and second wires extending in strip forms at a predetermined distance away from each other and including said conductor film while forming lamination films in the same strip forms as said first and second wires on said first and second wires; forming a second mask film extending on said lamination films in strip forms so as to intersect said first and second wires; and etching a portion of said lamination films in strip forms using said second mask film as a mask while leaving the other portions, thereby forming a magnetic memory cell operating as a memory cell.
