Patent ID: 6984870

Claim:
A cross-point switch, comprising: a semiconductor substrate having a face; a plurality of conductive elongate parallel input microstrips formed to extend over the face in a first direction and having a first general width substantially uniform along their lengths; a plurality of conductive elongate parallel output microstrips formed to extend over the face in a second direction at an angle to the first direction, the output microstrips having a second general width substantially uniform along their lengths, the output microstrips and the input microstrips intersecting at a plurality of intersections; widths of the input and output microstrips in the vicinity of their intersections with each other being narrowed from the first and second general widths, respectively; and switches formed at the intersections of the input microstrips and the output microstrips and controllable to connect ones of the input microstrips to ones of the output microstrips.
