    摘要: The present invention provides an interconnect structure that can be made in the BEOL which exhibits good mechanical contact during normal chip operations and does not fail during various reliability tests as compared with the conventional interconnect structures described above. The inventive interconnect structure has a kinked interface at the bottom of a via that is located within an interlayer dielectric layer. Specifically, the inventive interconnect structure includes a first dielectric layer having at least one metallic interconnect embedded within a surface thereof; a second dielectric layer located atop the first dielectric layer, wherein said second dielectric layer has at least one aperture having an upper line region and a lower via region, wherein the lower via region includes a kinked interface; at least one pair of liners located on at least vertical walls of the at least one aperture; and a conductive material filling the at least one aperture.

    摘要: A method of fabricating a MEMS switch having a free moving inductive element within in micro-cavity guided by at least one inductive coil. The switch consists of an upper inductive coil at one end of a micro-cavity; optionally, a lower inductive coil; and a free-moving inductive element preferably made of magnetic material. The coils are provided with an inner permalloy core. Switching is achieved by passing a current through the upper coil, inducing a magnetic field unto the inductive element. The magnetic field attracts the free-moving inductive element upwards, shorting two open conductive wires, closing the switch. When the current flow stops or is reversed, the free-moving magnetic element drops back by gravity to the bottom of the micro-cavity and the conductive wires open. When the chip is not mounted with the correct orientation, the lower coil pulls the free-moving inductive element back at its original position.
