Abstract
Disclosed is a crossover structure and method of fabricating such structure which contributes low capacitance to the circuit performance. The crossover utilizes a dielectric material which includes spheres of an insulating material in order to separate the conductors. In one aspect of the invention, a UV curable epoxy including hollow glass spheres is deposited on the crosspoint areas and the crossover connector deposited thereon. In another aspect of the invention, the crossover is formed with an air gap and the gap is subsequently filled with an encapsulating material including the spheres.
