Abstract
A pair of like, semiconductor integrated circuit bars, such as DRAMS, have second level bonding pads formed over their active surfaces in mirror images of one another. The bars then become bonded to opposite sides of frame bonding pads of a lead frame to double the capacity of a normally encapsulated integrated circuit. The normal bar bonding pads of the circuit bars are arranged identical to one another, and a patterned and etched second level of metal forms second level lands over the bar bonding pads, the mirror image second level bonding pads and second level leads connecting corresponding second level lands to second level pads. A pair of 256K DRAMS can be connected either 256K.times.2 or 512K.times.1 by use of dummy second level pads for DATA-IN/OUT and ROW ADDRESS STROBE connection.
