Abstract:
A microelectronic structure and a method for fabricating the microelectronic structure provide a plurality of voids interposed between a plurality of conductor layers. The plurality of voids is also located between a liner layer and an inter-level dielectric layer. The voids provide for enhanced electrical performance of the microelectronic structure.
Abstract:
A metallic dopant element having a greater oxygen-affinity than copper is introduced into, and/or over, surface portions of copper-based metal pads and/or surfaces of a dielectric material layer embedding the copper-based metal pads in each of two substrates to be subsequently bonded. A dopant-metal silicate layer may be formed at the interface between the two substrates to contact portions of metal pads not in contact with a surface of another metal pad, thereby functioning as an oxygen barrier layer, and optionally as an adhesion material layer. A dopant metal rich portion may be formed in peripheral portions of the metal pads in contact with the dopant-metal silicate layer. A dopant-metal oxide portion may be formed in peripheral portions of the metal pads that are not in contact with a dopant-metal silicate layer.
Abstract:
Embodiments include a metal-insulator-metal (MIM) capacitor having: a first electrode; a second electrode disposed proximate the first electrode; an insulator layer between the first and second electrodes; and a reactive layer positioned proximate the insulator layer and configured to allow altering of the reactive layer to change a capacitive value of the MIM capacitor, the reactive layer including a reactive conductor.
Abstract:
A method of fabricating a monolithic integrated circuit using a single substrate, the method including forming a first semiconductor layer from a substrate, fabricating semiconductor devices on the substrate, fabricating at least one metal wiring layer on the semiconductor devices, forming at least one dielectric layer in integral contact with the at least one metal wiring layer, forming contact openings through the at least one dielectric layer to expose regions of the at least one metal wiring layer, integrally forming, from the substrate, a second semiconductor layer on the dielectric layer, and in contact with the at least one metal wiring layer through the contact openings, and forming a plurality of non-linear semiconductor devices in said second semiconductor layer.
Abstract:
An integrated circuit and method includes a substrate, a plurality of semiconductor device layers monolithically integrated on the substrate, and a metal wiring layer with vias interconnecting the plurality of semiconductor device layers. The semiconductor device layers are devoid of bonding or joining interface with the substrate.
