Abstract:
1. A method of forming an air bridge structure between a first and second circuit component on a substrate, the method comprising: forming a support structure on the substrate; forming vias in support structure above the first and second circuit components; depositing a conductive layer so as to form vertically extending legs in the vias and a laterally extending member between the upper portions of the vertically extending legs in a manner so as to form an air bridge structure which electrically interconnect the first and second circuit components, wherein forming the laterally extending member results in an increased resistivity through the air bridge structure; removing the support structure so as to suspend the laterally extending member above the substrate between the first and second circuit components via the vertically extending legs, wherein removing the support structure results in an increased resistivity through the air bridge structure; and processing the air bridge structure by recrystallizing the laterally extending member and the vertically extending legs, which results in a decreased resistivity through the air bridge structure.
