Abstract:
An array, such as an MRAM (Magnetic Random Access Memory) array formed of a multiplicity of layered thin film devices, such as MTJ (Magnetic Tunnel Junction) devices, can be simultaneously formed in a multiplicity of horizontal widths in the 60 nm range while all having top electrodes with substantially equal thicknesses and coplanar upper surfaces. This allows such a multiplicity of devices to be electrically connected by a common conductor without the possibility of electrical opens and with a resulting high yield.

Claim (Index 1):
An array of devices, the array comprising:\n a common substrate; a multiplicity of N spatially separated multilayered devices having coplanar upper surfaces, the N multilayered devices being formed on the common substrate, wherein each of the N multilayered devices has a respective width d n , where n runs from 1 to N, and wherein the respective widths d n  are generally different; wherein the N multilayered devices have a common height h, and wherein each of the N multilayered devices comprises:\n a lower electrode; \n an active device element formed on the lower electrode; and \n an upper electrode formed on the active device element, wherein \n the upper electrodes of the N multilayered devices have identical thicknesses and wherein upper surfaces of the upper electrodes of the N multilayered devices are coplanar; a single top metal contact formed over the upper electrodes of the N multilayered devices, the single top metal contact being common to the N multilayered devices, the single top metal contact making open-free electrical contact with the upper electrodes of the N multilayered devices; and a space-filling insulating layer disposed between the N multilayered devices, wherein a space defined by the common substrate, adjacent devices of the N multilayered devices, and the single top metal contact is entirely filled by the space-filling insulating layer.
