Abstract
Abstract A crossover junction for miniaturized circuit construction including a first conductor mounted on a support layer, an insulator layer having a first section covering the length of the first conductor in the area of the junction and overlapping onto the support layer to form second and third sections on either side of the first conductor, each of the second and third sections of the insulating layer having a serrated outer edge, and a second conductor extending along the support layer transverse to the first conductor and extending across the insulating layer over the serrated edges.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
99 words
A crossover junction for miniaturized circuit construction including a first conductor mounted on a support layer, an intermediate insulator layer having a first section covering a length of said first conductor in the area of the junction and overlapping on to said support layer to form second and third sections on either side of said first conductor; each of said second and third sections of said intermediate insulator layer having a serrated outer edge, and a second conductor extending along said support layer transverse to said first conductor and extending across said intermediate insulator layer over said serrated edges.
Claim 2
Dependent Claim
99 words
A crossover junction for miniaturized circuit construction including a first conductor mounted on a support layer, an intermediate insulator layer having a first section covering a length of said first conductor in the area of the junction and overlapping on to said support layer to form second and third sections on either side of said first conductor; each of said second and third sections of said intermediate insulator layer having a serrated outer edge, and a second conductor extending along said support layer transverse to said first conductor and extending across said intermediate insulator layer over said serrated edges.
