Abstract:
1. A method of forming a memory cell, comprising: forming a first ovonic material over a first electrode material, the first ovonic material joining the first electrode material at a first interface; forming a second electrode material over the first ovonic material, the first ovonic material joining the second electrode material at a second interface; forming a second ovonic material over the second electrode material, the second ovonic material joining the second electrode material at a third interface; forming a third electrode material over the second ovonic material, the second ovonic material joining the third electrode material at a fourth interface; one of the first and second ovonic materials being an ovonic memory material, and the other of the first and second ovonic materials being an ovonic threshold switch material; and implanting dopant into the first and second ovonic materials, and into the first, second and third electrodes to form damage regions extending across the first, second, third and fourth interfaces and to improve adhesion of the ovonic materials and electrode materials across said interfaces.
