A method for making a laminated chip includes: (a) forming a first conductive layer on a substrate; (b) forming an insulating layer on the first conductive layer opposite to the substrate; (c) bombarding the insulating layer using an electron beam to form a plurality of holes that expose the first conductive layer; and (d) forming a second conductive layer on the insulating layer such that a part of the second conductive layer extends into the holes to electrically connect to the first conductive layer.
