  • Patent number: 9947721
    Abstract: Methods, systems, and devices for a three-dimensional memory array are described. Memory cells may transform when exposed to elevated temperatures, including elevated temperatures associated with a read or write operation of a neighboring cell, corrupting the data stored in them. To prevent this thermal disturb effect, memory cells may be separated from one another by thermally insulating regions that include one or several interfaces. The interfaces may be formed by layering different materials upon one another or adjusting the deposition parameters of a material during formation. The layers may be created with planar thin-film deposition techniques, for example.

  • Patent number: 9893041
    Abstract: Backplane-side bonding structures including a common metal are formed on a backplane. Multiple source coupons are provided such that each source coupon includes a transfer substrate and an array of devices to be transferred. Each array of devices are arranged such that each array includes a unit cell structure including multiple devices of the same type and different types of bonding structures including different metals that provide different eutectic temperatures with the common metal. Different types of devices can be sequentially transferred to the backplane by sequentially applying the supply coupons and selecting devices providing progressively higher eutectic temperatures between respective bonding pads and the backplane-side bonding structures. Previously transferred devices stay on the backplane during subsequent transfer processes, enabling formation of arrays of different devices on the backplane.
