Abstract

An electrical circuit arrangement includes a conductive link through an insulating layer separating two conductive layers. This link is formed by placing an evaporable plug on a first conductive layer, forming the insulating layer around it and then vaporising the plug. The resulting gap is then infilled with conductive material and a second conductive layer formed on the insulating layer.
