  • Publication number: 20240099151
    Abstract: A first conductive layer is patterned and trimmed to form a sub 30 nm conductive via on a first bottom electrode. The conductive via is encapsulated with a first dielectric layer and planarized to expose a top surface of the conductive via. A second conductive layer is deposited over the first dielectric layer and the conductive via. The second conductive layer is patterned to form a sub 60 nm second conductive layer wherein the conductive via and second conductive layer together form a T-shaped second bottom electrode. MTJ stacks are deposited on the T-shaped second bottom electrode and on the first bottom electrode wherein the MTJ stacks are discontinuous. A second dielectric layer is deposited over the MTJ stacks and planarized to expose a top surface of the MTJ stack on the T-shaped second bottom electrode. A top electrode contacts the MTJ stack on the T-shaped second bottom electrode plug.

  • Publication number: 20240088095
    Abstract: A method for forming a chip package structure. The method includes bonding first connectors over a front surface of a semiconductor wafer. The method also includes dicing the semiconductor wafer from a rear surface of the semiconductor wafer to form semiconductor dies and mounting first and second semiconductor dies in the semiconductor dies over a top surface of the interposer substrate. The method further forming an encapsulating layer over the top surface of the interposer substrate to cover the first semiconductor die and the second semiconductor die. A first sidewall of the first semiconductor die faces a second sidewall of the second semiconductor die, and upper portions of the first sidewall and the second sidewall have a tapered contour, to define a top die-to-die distance and a bottom die-to-die distance that is less than the top die-to-die distance.

  • Patent number: 11930715
    Abstract: A conductive via layer is deposited on a bottom electrode, then patterned and trimmed to form a sub 20 nm conductive via on the bottom electrode. The conductive via is encapsulated with a first dielectric layer, which is planarized to expose a top surface of the conductive via. A MTJ stack is deposited on the encapsulated conductive via wherein the MTJ stack comprises at least a pinned layer, a barrier layer, and a free layer. A top electrode layer is deposited on the MTJ stack and patterned and trimmed to form a sub 30 nm hard mask. The MTJ stack is etched using the hard mask to form an MTJ device and over etched into the encapsulation layer but not into the bottom electrode wherein metal re-deposition material is formed on sidewalls of the encapsulation layer underlying the MTJ device and not on sidewalls of a barrier layer of the MTJ device.
