A leadframe carrier and insert compatible with a temperature-affectable, expandable and contractable leadframe strip to be bonded with a selected plurality of semiconductor chips, said carrier being automatically separable and removable with regard to said insert during manufacture despite possible clinging which may be induced by the expansion and contraction of said carrier insert.

Method for holding a strip of conductive lead frames

Universal leadframe carrier

An apparatus for inverting and handling integrated circuit dice employs rotating apparatus for rotating a chip carrier by 180 degrees to invert and transfer dice from one set of receptacles to another; together with an apparatus for precisely aligning dice resting at random positions within a set of oversized receptacles.

Manipulation and handling of integrated circuit dice

Uniform leadframe carrier

An apparatus for removing selected integrated circuit dice from a wafer array of dice sequentially moves a striker above a tape to the underside of which the array is mounted and then knocks a die down from the array of dice into a receptacle for transport to further processing stages.

Chip selection in automatic assembly of integrated circuit

A method of forming leadframes for use in manufacturing semiconductor chips starts with fabricating a plurality of leadframes by metal stamping or etching leadframe patterns into a flat ribbon of conductive material. The leadframe patterns include a plurality of outwardly radiating leads, inner radiating leads, and a central perimeter for interconnecting the outwardly and inner radiating leads. The outwardly radiating leads are arranged in groups, each of which are directed along planar perpedicular coordinates. The inner radiating leads have 180 degrees turns in the plane of the leadframe. The inner radiating leads are then successively bent at an acute angle and parallel to the plane of said leadframe so that the inner radiating leads are offset from the plane of the leadframe. The bending is performed in such a manner that each of the leads are formed with a stable spring force for effective bonding to corresponding semiconductor chip pads.

A leadframe for an integrated circuit includes a set of individual leads temporarily connected in an array; each lead having an exterior portion shaped in a standard form and an interior portion shaped to form a standard array of contacts and to have the same spring constant for deflections perpendicular to the plane of the leadframe.

Integrated-circuit leadframe adapted for a simultaneous bonding operation

An integrated circuit chip includes a top layer of dielectric penetrated by conductive vias connecting electrical contacts within the integrated circuit proper to a network of electrical leads disposed on top of the dielectric layer; the network of leads, in turn, being connected to an array of contact pads adapted for simultaneous solder connection to a leadframe.

Zero power random access memory package

A system for the assembly and packaging of integrated circuits employs circuit dice that have contact pads in a standard array; a leadframe having leads configured to have the same spring constant; a method for removing selected dice from a wafer array under computer control; and a method of simultaneously bonding all leads to the die.
