Abstract:
1. An integrated circuit package comprising: an integrated circuit die, said integrated circuit die having a top side and a bottom side opposite said top side, said top side including at least one bond pad; at least one raised interconnect located over and conductively coupled to said at least one bond pad; and a single-layer solid flexible dielectric circuit film having a thickness of 10,000 to 200,000 Angstroms, a top surface, a bottom surface and a routing conductor, the flexible circuit film having at least one outer landing formed on the top surface and at least one inner landing formed on the bottom surface such that the landings on the top and bottom surfaces are fully supported by the circuit film, wherein the outer landing is laterally offset from the inner landing and the two landings are connected via the routing conductor, which extends laterally within the single-layer solid flexible dielectric circuit film, wherein the flexible circuit film being located over and conductively attached to at least one raised interconnect such that an air gap is formed between said integrated circuit die and said flexible circuit film wherein said air gap has a height in the range of between about 10-500 microns.
