Latest Patents

Nakanishi's latest patents include innovative designs aimed at improving semiconductor devices. One notable patent is for a semiconductor device and ball bonder. This invention inhibits the formation of cracks under a pad opening during ball bonding without increasing the chip size. The protective film includes a pad opening that exposes part of the topmost layer metal film of the chip. A second metal film, provided under the pad opening, has a ring shape that defines a rectangular opening. The opening edge of the second metal film extends inwardly beyond the edge of the overlying pad opening, with vias connecting the two metal films located outside the pad opening in plan view.

Another significant patent is for a semiconductor device and its manufacturing method. This device features a semiconductor substrate with a scribe region and an IC region. A first insulating film is disposed across both regions, with at least one separation groove in the scribe region. Side walls made of a plug metal film are formed only on the lateral walls of the separation groove, ensuring that the plug metal film does not extend out of the groove or exist on the upper surface of the first insulating film. A second insulating film covers the side walls, providing additional protection.
