A method and structure for a fuse structure comprises an insulator layer, a plurality of fuse electrodes extending through the insulator layer to an underlying wiring layer, an electroplated fuse element connected to the electrodes, and an interface wall. The fuse element is positioned external to the insulator, with a gap juxtaposed between the insulator and the fuse element. The interface wall further comprises a first side wall, a second side wall, and an inner wall, wherein the inner wall is disposed within the gap. The fuse electrodes are diametrically opposed to one another, and the fuse element is perpendicularly disposed above the fuse electrodes. The fuse element is either electroplatted, electroless plated, or is an ultra thin fuse.

A multilevel air-gap-containing interconnect structure and a method of fabricating the same are provided. The multilevel air-gap-containing interconnect structure includes a collection of interspersed line levels and via levels, with via levels comprising conductive vias embedded in one or more dielectric layers in which the dielectric layers are solid underneath and above line features in adjacent levels, and perforated between line features. The line levels contain conductive lines and an air-gap-containing dielectric. A solid dielectric bridge layer, containing conductive contacts and formed by filling in a perforated dielectric layer, is disposed over the collection of interspersed line and via levels.

A micro-electro mechanical switch having a restoring force sufficiently large to overcome stiction is described. The switch is provided with a deflectable conductive beam and multiple electrodes coated with an elastically deformable conductive layer. A restoring force which is initially generated by a single spring constant k0 upon the application of a control voltage between the deflectable beam and a control electrode coplanar to the contact electrodes is supplemented by adding to k0 additional spring constants k1, . . . , kn provided by the deformable layers, once the switch nears closure and the layers compress. In another embodiment, deformable, spring-like elements are used in lieu of the deformable layers. In an additional embodiment, the compressible layers or deformable spring-like elements are affixed to the deflecting beam facing the switch electrodes

A micro-electromechanical (MEM) RF switch provided with a deflectable membrane (60) activates a switch contact or plunger (40). The membrane incorporates interdigitated metal electrodes (70) which cause a stress gradient in the membrane when activated by way of a DC electric field. The stress gradient results in a predictable bending or displacement of the membrane (60), and is used to mechanically displace the switch contact (30). An RF gap area (25) located within the cavity (250) is totally segregated from the gaps (71) between the interdigitated metal electrodes (70). The membrane is electrostatically displaced in two opposing directions, thereby aiding to activate and deactivate the switch. The micro-electromechanical switch includes: a cavity (250); at least one conductive path (20) integral to a first surface bordering the cavity; a flexible membrane (60) parallel to the first surface bordering the cavity (250), the flexible membrane (60) having a plurality of actuating electrodes (70); and a plunger (40) attached to the flexible membrane (60) in a direction away from the actuating electrodes (70), the plunger (40) having a conductive surface that makes electric contact with the conductive paths, opening and closing the switch.

摘要:
The present invention provides a permanent protective hardmask which protects the dielectric properties of a main dielectric layer having a desirably low dielectric constant in a semiconductor device from undesirable increases in the dielectric constant, undesirable increases in current leakage, and low device yield from surface scratching during subsequent processing steps. The protective hardmask further includes a single layer or dual layer sacrificial hardmask particularly useful when interconnect structures such as via openings and/or lines are formed in the low dielectric material during the course of making the final product. The sacrificial hardmask layers and the permanent hardmask layer may be formed in a single step from a same precursor wherein process conditions are altered to provide films of differing dielectric constants. Most preferably, a dual damascene structure has a tri-layer hardmask comprising silicon carbide BLoK™, PECVD silicon nitride, and PECVD silicon dioxide, respectively, formed over a bulk low dielectric constant interlevel dielectric prior to forming the interconnect structures in the interlevel dielectric.
