Abstract:
An intermediate base for a module having at least one semiconductor component, said base comprising a flat base body having an upper face on which internal connections are formed for connection to connecting elements of a semiconductor component, a lower face which is provided with external connections for making contact with a circuit carrier, said base body being a film composed of plastic material whose coefficient of expansion is approximately the same as the coefficient of expansion of the semiconductor component and having through-holes between the upper face and the lower face, said through-holes having walls of said plastic material being at least partially metallized to make a conductive connection between each internal connection on the upper face and a corresponding external connection on the lower face, the walls of the through-holes being at least partially exposed in the region of the lower face of the base body by means of annular notches which are incorporated adjacent to a circumferential edge of the through-holes to form freestanding studs as external connections, said studs having an outer rim in the plane of the lower face.
