Structure and self-locating method of making capped chips

摘要

A method of making the lidded chip assembly are provided which includes the steps of: (a) aligning a lid member with a chip member including one or more chips so that electrically conductive elements projecting from a front surface of the chip-member extend into through-holes in the lid member and at least partially control location of the lid member relative to the chip member in one or more horizontal directions parallel to the front surface; and (b) forming interconnections extending through the lid member so that the interconnections include the conductive elements. A capped chip is provided in which the conductive interconnects extend from the chip through openings in a cap member, the openings being tapered to become smaller in a direction from the bottom or inner surface of the opening towards the top or outer surface.
