Patent number: 9548158Abstract: A three-dimensional multipath inductor includes turns disposed about a center region on two layers, the turns on the two layers having corresponding geometry therebetween. Each of the turns is comprised of two or more segments that extend length-wise along the turns, and the segments have positions that vary from an innermost position relative to the center region and an outermost position relative to the center region. A lateral cross-over is configured to couple the segments of at least one turn on one layer with the segments on a turn on a same layer to form segment paths that have a substantially same length for all segment paths in a grouping of segment paths on that same layer. A vertical cross-over is configured to couple the segments on different vertically stacked metal layers to have the segment groups with a substantially same length for all segment paths based on vertical lengths.Type: GrantFiled: December 2, 2014Date of Patent: January 17, 2017Assignee: GLOBALFOUNDRIES INC.Inventors: Robert A. Groves, Sarath L. K. Parambil, Venkata Nr. Vanukuru
