Abstract: An embodiment integrates memory, such as spin-torque transfer magnetoresistive random access memory (STT-M RAM) within a logic chip. The STT-MRAM includes a magnetic tunnel junction (MTJ) that has an upper MTJ layer, a lower MTJ layer, and a tunnel barrier directly contacting the upper MTJ layer and the lower MTJ layer; wherein the upper MTJ layer includes an upper MTJ layer sidewall and the lower MTJ layer includes a lower MTJ sidewall horizontally offset from the upper MTJ layer. Another embodiment includes a memory area, comprising a MTJ, and a logic area located on a substrate; wherein a horizontal plane intersects the MTJ, a first Inter-Layer Dielectric (ILD) material adjacent the MTJ, and a second ILD material included in the logic area, the first and second ILD materials being unequal to one another. Other embodiments are described herein.

Abstract: Amorphous and polycrystalline III-V semiconductor including (Ga,As), (Al,As), (In,As), (Ga,N), and (Ga,P) materials were grown at low temperatures on semiconductor substrates. After growth, different substrates containing the low temperature grown material were pressed together in a pressure jig before being annealed. The annealing temperatures ranged from about 300° C. to 800° C. for annealing times between 30 minutes and 10 hours, depending on the bonding materials. The structures remained pressed together throughout the course of the annealing. Strong bonds were obtained for bonding layers between different substrates that were as thin as 3 nm and as thick as 600 nm. The bonds were ohmic with a relatively small resistance, optically transparent, and independent of the orientation of the underlying structures.
