Patent ID: 8748944

Claim:
An electrical circuit, comprising: a substrate which extends in one plane; a first layer spanning over a defined area of the substrate; a second layer arranged over the first layer spanning over the defined area; an insulating layer arranged between the first and second layers spanning over the defined area; a plurality of unit cells arranged adjacently on the first layer each having first, second, and third contact points; first, second and third contact surfaces insulated from each other and arranged on the second layer together covering the second layer substantially completely; and a plurality of openings arranged in the insulating layer providing through-contacting to connect the first, second, and third contact surfaces to the first, second, and third contact points of the unit cells, wherein the first contact surface is connected to the first contact point of each unit cell, the second contact surface is connected to the second contact point of each unit cell, and the third contact surface is connected to the third contact point of each unit cell.
