    Abstract: One or more diffusion barriers are formed around one or more conductors in a three dimensional or 3D memory cell. The diffusion barriers allow the conductors to comprise very low resistivity materials, such as copper, that may otherwise out diffuse into surrounding areas, particularly at elevated processing temperatures. Utilizing lower resistivity materials allows device dimension to be reduced by mitigating increases in resistance that occur when the size of the conductors is reduced. As such, more cells can be produced over a given area, thus increasing the density and storage capacity of a resulting memory array.

    Abstract: A semiconductor wafer assembly includes a base of dielectric. A layer of silicon is deposited thereover. A metal hard mask is deposited over the silicon. A dielectric hard mask is deposited over the metal hard mask. Photoresist is deposited over the dielectric hard mask, whereby a plurality of sacrificial columns is formed from the layer of metal hard mask through the photoresist such that the sacrificial columns extend out from the silicon layer. An interface layer is disposed between the layer of conductive material and the layer of hard mask to enhance adhesion between each of the plurality of sacrificial columns and the layer of conductive material to optimize the formation of junction diodes out of the silicon by preventing the plurality of sacrificial columns from being detached from the layer of silicon prematurely due to the sacrificial columns peeling or falling off.

The recording region has a data region pattern and a plurality of servo region patterns formed substantially in circular arcs which radially extend from the center hole side of the substrate to an outer peripheral edge portion thereof and divide the data region pattern in a plurality of parts in the circumferential direction of the substrate. Each servo region pattern has a radius larger than that of the outmost periphery of the substrate and a center of the circular arc on a circular path concentric with the substrate. The data region pattern and each of the servo region patterns have different magnetic occupancies and different optical reflection factors.
