A lead frame for mounting LED elements includes a frame body region and a large number of package regions arranged in multiple rows and columns in the frame body region. The package regions each include a die pad on which an LED element is to be mounted and a lead section adjacent to the die pad, the package regions being further constructed to be interconnected via a dicing region. The die pad in one package region and the lead section in another package region upward or downward adjacent to the package region of interest are connected to each other by an inclined reinforcement piece positioned in the dicing region.

To provide a technique capable of reducing the chip size of a semiconductor chip and particularly, a technique capable of reducing the chip size of a semiconductor chip in the form of a rectangle that constitutes an LCD driver by devising a layout arrangement in a short-side direction. In a semiconductor chip that constitutes an LCD driver, input protection circuits are arranged in a lower layer of part of a plurality of input bump electrodes and on the other hand, in a lower layer of the other part of the input bump electrodes, the input protection circuits are not arranged but SRAMs (internal circuits) are arranged.

A method for fabricating bump structure without UBM undercut uses an electroless Cu plating process to selectively form a Cu UBM layer on a Ti UBM layer within an opening of a photoresist layer. After stripping the photoresist layer, there is no need to perform a wet etching process on the Cu UBM layer, and thereby the UBM structure has a non-undercut profile.

Copper or a copper alloy characterized in having an α-ray emission of 0.001 cph/cm2 or less. Since recent semiconductor devices are produced to have higher density and higher capacity, there is greater risk of soft errors caused by the influence of α rays emitted from materials positioned near semiconductor chips. In particular, there are strong demands for achieving higher purification of copper and copper alloys which are used near the semiconductor device, such as copper or copper alloy wiring lines, copper or copper alloy bonding wires, and soldering materials, and materials reduced in α-ray emission are also demanded. Thus, the present invention elucidates the phenomenon in which α rays are emitted from copper or copper alloys, and provides copper or copper alloy reduced in α-ray emission which is adaptable to the demanded material, and a bonding wire in which such copper or copper alloy is used as its raw material.
