Patent ID: 7052933

Claim:
A method of manufacturing an electronic device which comprises an electronic element provided with first connection regions and with an electrically insulating envelope, which method comprises of: providing a recess in a first surface of a carrier plate, said plate comprising in that order a first layer of aluminum and a second layer of copper which recess extends from the first surface through the second layer at least to the first layer; wherein the recess extends into the first layer, such that underetching takes place in the first layer with respect to the second layer under formation of a cavity, said cavity is filled up by the insulating envelope; providing the electric element on or above the surface of the carrier plate; electrically connecting the first connection regions to portions of the second layer lying within the recess; surrounding the electric element by means of the insulating envelope which fills up the recess in the carrier plate at least substantially; and removing the first layer of the carrier plate from the second layer of the carrier plate, which second layer faces away from the first surface, to at least an extent such that the recess filled by a portion of the envelope is reached, whereby second connection regions are formed by the portions of the second layer lying within the recess.
