To provide a highly reliable semiconductor device that is suitable for miniaturization and an increase in density. The semiconductor device includes a first insulator over a substrate, a transistor including an oxide semiconductor over the first insulator, a second insulator over the transistor, and a third insulator over the second insulator. The first insulator and the third insulator have a barrier property with respect to oxygen and hydrogen. The second insulator includes an excess-oxygen region. The transistor is enclosed with the first insulator and the third insulator that are in contact with each other in an edge of a region where the transistor is positioned.

A three-dimensional (3D) non-volatile memory array having a silicide bit line and method of fabricating is disclosed. The fabrication technique may comprise forming a metal silicide for at least a portion (546a, 546b) of the bit line (530). The device has reversible resistivity material (532) between the word lines (536) and the bit lines (530). The reversible resistivity material may be a metal oxide. The metal that is used to form the silicide may serve as an oxygen scavenger to draw oxygen away from the silicon, thus preventing formation of silicon oxide between the reversible resistivity material and the bit line. The metal silicide may also help prevent formation of a depletion layer in silicon in the bit line.

Techniques are disclosed for forming a through-body-via (TBV) isolated coaxial capacitor in a semiconductor die. In some embodiments, a cylindrical capacitor provided using the disclosed techniques may include, for example, a conductive TBV surrounded by a dielectric material and an outer conductor plate. The TBV and outer plate can be formed, for example, so as to be self-aligned with one another in a coaxial arrangement, in accordance with some embodiments. The disclosed capacitor may extend through the body of a host die such that its terminals are accessible on the upper and/or lower surfaces thereof. Thus, in some cases, the host die can be electrically connected with another die to provide a die stack or other three-dimensional integrated circuit (3D IC), in accordance with some embodiments. In some instances, the disclosed capacitor can be utilized, for example, to provide integrated capacitance in a switched-capacitor voltage regulator (SCVR).

Embodiments disclosed in the detailed description include a complete system-on-chip (SOC) solution using monolithic three dimensional (3D) integrated circuit (IC) (3DIC) integration technology. The present disclosure includes example of the ability to customize layers within a monolithic 3DIC and the accompanying short interconnections possible between tiers through monolithic intertier vias (MIV) to create a system on a chip. In particular, different tiers of the 3DIC are constructed to support different functionality and comply with differing design criteria. Thus, the 3DIC can have an analog layer, layers with higher voltage threshold, layers with lower leakage current, layers of different material to implement components that need different base materials and the like. Unlike the stacked dies, the upper layers may be the same size as the lower layers because no external wiring connections are required.
