    摘要: High quality factor (Q) spiral and toroidal inductor and transformer are disclosed that are compatible with silicon very large scale integration (VLSI) processing, consume a small IC area, and operate at high frequencies. The spiral inductor has a spiral metal coil deposited in a trench formed in at dielectric layer over a substrate. The metal coil is enclosed in ferromagnetic liner and cap layers, and is connected to an underpass contact through a metal filled via in the dielectric layer. The spiral inductor also includes ferromagnetic cores lines surrounded by the metal spiral coil. A spiral transformer is formed by vertically stacking two spiral inductors, or placing them side-by-side over a ferromagnetic bridge formed below the metal coils and cores lines. The toroidal inductor includes a toroidal metal coil with a core having ferromagnetic strips. The toroidal metal coil is segmented into two coils each having a pair of ports to form a toroidal transformer.

    摘要: Methods and apparatus for forming through-vias are presented, for example, a method for forming a via in a portion of a semiconductor wafer comprising a substrate. The method comprises forming a trench surrounding a first part of the substrate such that the first part is separated from a second part of the substrate, forming a hole through the substrate within the first part, and forming a first metal within the hole. The trench extends through the substrate. The first metal extends from a front surface of the substrate to a back surface of the substrate. The via comprises the hole and the first metal.

    摘要: A method of formation of a microelectromechanical system (MEMS) resonator or filter which is compatible with integration with any analog, digital, or mixed-signal integrated circuit (IC) process, after or concurrently with the formation of the metal interconnect layers in those processes, by virtue of its materials of composition, processing steps, and temperature of fabrication is presented. The MEMS resonator or filter incorporates a lower metal level, which forms the electrodes of the MEMS resonator or filter, that may be shared with any or none of the existing metal interconnect levels on the IC. It further incorporates a resonating member that is comprised of at least one metal layer for electrical connection and electrostatic actuation, and at least one dielectric layer for structural purposes. The gap between the electrodes and the resonating member is created by the deposition and subsequent removal of a sacrificial layer comprised of a carbon-based material. The method of removal of the sacrificial material is by an oxygen plasma or an anneal in an oxygen containing ambient. A method of vacuum encapsulation of the MEMS resonator or filter is provided through means of a cavity containing the MEMS device, filled with additional sacrificial material, and sealed. Access vias are created through the membrane sealing the cavity; the sacrificial material is removed as stated previously, and the vias are re-sealed in a vacuum coating process.
