Abstract: A three-dimensional memory array may include a first memory array and a second memory array, stacked above the first. Some memory cells of the first array may be coupled to a first layer selector transistor, while some memory cells of the second array may be coupled to a second layer selector transistor. The first and second layer selector transistor may be coupled to one another and to a peripheral circuit that controls operation of the first and/or second memory arrays. A different layer selector transistor may be used for each row of memory cells of a given memory array and/or for each column of memory cells of a given memory array. Such designs may allow increasing density of memory cells in a memory array having a given footprint area, or, conversely, reducing the footprint area of the memory array with a given memory cell density.

Abstract: Various three-dimensional devices that can be formed within the bulk of a semiconductor by photo-controlled selective etching are described herein. With more particularity, semiconductor devices that incorporate three-dimensional electrical vias, waveguides, or fluidic channels that are disposed within a semiconductor are described herein. In an exemplary embodiment, a three-dimensional interposer chip includes an electrical via, a waveguide, and a fluidic channel, wherein the via, the waveguide, and the fluidic channel are disposed within the body of a semiconductor element rather than being deposited on a surface. The three-dimensional interposer is usable to make electrical, optical, or fluidic connections between two or more devices.
