    摘要: A static redundancy arrangement for a circuit using a focused ion beam anti-fuse methodology which reduces the circuit layout area and the switching activity compared to a prior art dynamic redundancy scheme, resulting in less power, a simpler design and higher speed. Focused ion beam anti-fuse methodology is used to program redundancy for circuits, particularly wide I/O embedded DRAM macros. An anti-fuse array circuit is comprised of a plurality of anti-fuse programming elements, each of which comprises a latch circuit controlled by a set input signal, and an anti-fuse device which is programmed by a focused ion beam.

    摘要: Disclosed is a structure and process for incorporating air or other gas as a permanent dielectric medium in a multilevel chip by providing CVD diamond as a semi-sacrificial interlevel and intralevel dielectric material. The semi-sacrificial dielectric is subsequently at least partially removed in an isotropic oxygen etch. A variation of the disclosure includes providing a final, permanent CVD diamond encapsulant to contain the gaseous dielectric medium within the chip.

    摘要: An epitaxial semiconductor layer or a stack of a silicon germanium alloy layer and an epitaxial strained silicon layer is formed on outer sidewalls of a porous silicon portion on a substrate. The porous silicon portion and any silicon germanium alloy material are removed and a semitubular epitaxial semiconductor structure in a three-walled configuration is formed. A semitubular field effect transistor comprising inner and outer gate dielectric layers, an inner gate electrode, an outer gate electrode, and source and drain regions is formed on the semitubular epitaxial semiconductor structure. The semitubular field effect transistor may operate as an SOI transistor with a tighter channel control through the inner and outer gate electrodes, or as a memory device storing electrical charges in the body region within the semitubular epitaxial semiconductor structure.
