Abstract
A three dimensional electrical component having a first side and a second side formed from an electrically insulating polymer matrix capable of heat conversion to an electrically conducting polymer matrix has at least one passageway from the first side to the second side having a tapered wall slope configuration from the first side to the second side with constantly changing cross section of the passageway from the first side through the passageway to the second side, an electrically conducting path between the first side and the second side formed by the in situ heat conversion of the walls of the passageway in the electrically insulating polymer matrix. In a preferred embodiment the electrically conducting path is formed by directing a laser beam to the walls of the passageway to heat the insulating polymer matrix to a temperature sufficient to convert it to an electrically conducting polymer matrix.
