A method and device relating the electrical interconnection of angularly disposed conductive is disclosed. Conventional wire bonding equipment is used to apply a wire ball on a first conductive surface in an electronic assembly. A conductive wire is drawn up vertically and terminated such that the central portion of the wire is proximal the second conductive surface. The electronic assembly is reoriented with respect to the travel of the capillary whereby a stitch bond is defined upon the second conductive surface to define an interconnect wire and a terminal wire portion, which terminal wire portion is removed.

Wire bond method for angularly disposed conductive pads and a device made from the method

An improved low-loss waveguide crossover uses an out-of-plane, such as vertical, waveguide to bridge over any number of waveguides with very low, or essentially no, optical loss or crosstalk. Optical signals transmitted in a waveguide system having the improved waveguide crossover can cross over one or multiple transverse waveguides with a greatly reduced loss of signal intensity by using a second waveguide (such as a bridge) positioned in a second plane different from the plane containing the transverse waveguides. An optical signal from the input waveguide is coupled efficiently through directional coupling to the bridge waveguide and optionally from the bridge waveguide to the output waveguide. Methods for fabricating the improved waveguide crossover are described.
