Abstract: A multiple fragment impact test specimen, and a method for using it in multiple fragment impact tests against a target, is disclosed. The test specimen comprises two or more fragments fixed to one or more connecting members so that the fragments are held at a fixed distance apart during their flight to a target. The orientation and speed of the fragments at the moment of impacting the target are measured and the measurements are used to calculate the exact spacing and time delay between the individual fragment impacts. An experimenter can control the range of fragment spacings and time delays for a series of tests by choosing the lengths of the connecting members and thereby fixing the relative distances between the fragments.

Abstract: An epitaxial barrier material provides not only a unique growth medium for growing single crystal structures of elemental metal thereon, but also provides an effective diffusion barrier at extremely thin thicknesses against migration of atoms from the metallization layer into an adjacent semiconductor substrate or low dielectric insulation layer. This invention is particularly advantageous for forming single crystal, transition metal conductor lines, contacts, filled trenches, and/or via plugs, and especially conductor structures based on transition metals of copper, silver, gold, or platinum. These metals are highly attractive for interconnect strategies on account of there respective low resistivity and high reliability characteristics. Processes for making the barrier film in a semiconductor device are also covered.

Abstract: Using irregular optical interconnections to compensate for non-uniformities in analog optical processors, such as matrix-vector (M-V) optical processors, is disclosed. An M-V processor of one embodiments includes two optical devices, such as spatial light modulators (SLM's). One of the devices represents a matrix, and the other device represents a vector. Each device has non-uniformities. The non-uniformities of the devices are at least substantially matched to one another, where the optical interconnections between the devices are irregular. Light traveling through the devices represents the product of the matrix and the vector. An analog-to-digital (A/D) processor, or converter, can be used to subtract any errors in the product even after substantially matching the non-uniformities, by non-digital electrical or photonic processing.

Abstract: A semiconductor device having a barrier film comprising an extremely thin film formed of one or more monolayers each comprised of a two-dimensional array of metal atoms. In one exemplary aspect, the barrier film is used for preventing the diffusion of atoms of another material, such as a copper conductor, into a substrate, such as a semiconducting material or an insulating material. In one mode of making the semiconductor device, the barrier film is formed by depositing a precursor, such as a metal halide (e.g., BaF2), onto the substrate material, and then annealing the resulting film on the substrate material to remove all of the constituents of the temporary heteroepitaxial film except for a monolayer of metal atoms left behind as attached to the surface of the substrate. A conductor, such as copper, deposited onto the barrier film is effectively prevented from diffusing into the substrate material even when the barrier film is only one or several monolayers in thickness.
