摘要:
In a method for preserving an air bridge structure on an integrated circuit chip, a protective layer is plasma-deposited over the top and sides of the air bridge. A high density interconnect structure is applied over the chip and protective layer. The protective film provides mechanical strength during the application of the high density interconnect structure to prevent deformation. It also prevents any contamination from intruding under the air bridge. More importantly, the protective film only negligibly impedes the performance of the air bridge and therefore does not need to be removed, thereby eliminating the necessity of ablating the HDI structure.

A technique for fabricating a resistor on a flexible substrate. Specifically, at least a portion of a polyimide substrate is activated by exposure to a ion sputter etch techniques. A metal layer is disposed over the activated portion of the substrate, thereby resulting in the formation of a highly resistive metal-carbide region. Interconnect layers are disposed over the metal-carbide region and patterned to form terminals at opposite ends of the metal carbide region. The metal-carbide region is patterned to form a resistor between the terminals. Alternatively, only a selected area of the polyimide substrate is activated. The selected area forms the area in which the metal-carbide region is formed. Interconnect layers are disposed over the metal-carbide region and patterned to form terminals at opposite ends of the metal-carbide region.

An insulating layer with at least one via is provided over a metal plate. A sacrificial layer is applied over a portion of the insulating layer so that the sacrificial layer extends into the via. A metal bridge having at least one opening is provided over a portion of the sacrificial layer and a portion of the insulating layer so that the metal bridge extends over the via and the opening is situated adjacent a portion of the sacrificial layer. A reinforcing seal layer with a well is provided over the metal bridge so that the well is situated adjacent to at least a portion of the opening. The sacrificial layer is then removed.

A substrate stack is suspended within a stack holder to position upper and lower stack surfaces coplanar with upper and lower holder surfaces. Laminating heat and pressure is simultaneously applied to the upper and lower surfaces to laminate a carrier interconnect film to top and bottom stack portions simultaneously. Subsequent wet chemical processing of both stack edges may also be simultaneous to effect savings in manufacturing costs.

A low temperature batch method for forming and positioning permanent magnets on electromagnetically actuated micro-fabricated components, such as electrical switches employs a first adhesive, such as a Siltem/epoxy blend of an epoxy resin and a siloxane polyimide polymer, to releasably attach a mold layer of Kapton polyimide to a substrate, which may be the movable portion of a micromechanical structure, or a precursor to such movable portion. A well-shape cavity is formed in the mold layer, and filled with a slurry of rare earth NdFeB magnetic particles suspended in a second adhesive, which is cured to form the body of a magnet. The second adhesive is an SPI/epoxy blend, also of an epoxy resin and a siloxane polyimide polymer, but with a greater adhesion strength and a higher temperature softening point compared to the Siltem/epoxy blend. The entire structure is heated, and the mold layer is pulled off the substrate, while the body of magnetic material remains firmly attached. Selective etchants may be subsequently employed to remove metal sacrificial layers, while the NdFeB magnetic particles are protected from attack by the etchant by being effectively encased in plastic.

An embedded chip package (ECP) includes a plurality of re-distribution layers joined together in a vertical direction to form a lamination stack, each re-distribution layer having vias formed therein. The embedded chip package also includes a first chip embedded in the lamination stack and a second chip attached to the lamination stack and stacked in the vertical direction with respect to the first chip, each of the chips having a plurality of chip pads. The embedded chip package further includes an input/output (I/O) system positioned on an outer-most re-distribution layer of the lamination stack and a plurality of metal interconnects electrically coupled to the I/O system to electrically connect the first and second chips to the I/O system. Each of the plurality of metal interconnects extends through a respective via to form a direct metallic connection with a metal interconnect on a neighboring re-distribution layer or a chip pad on the first or second chip.
