A leadframe has a die pad area and an outer layer of a first metal having a first oxidation potential. The leadframe is placed in contact with a solution containing a second metal having a second oxidation potential, the second oxidation potential being more negative than the first oxidation potential. Radiation energy is then applied to the die pad area of the leadframe contacted with the solution to cause a local increase in temperature of the leadframe. As a result of the temperature increase, a layer of said second metal is selectively provided at the die pad area of the leadframe by a galvanic displacement reaction. An oxidation of the outer layer of the leadframe is then performed to provide an enhancing layer which counters device package delamination.

METHOD OF MANUFACTURING SEMICONDUCTOR DEVICES AND CORRESPONDING SEMICONDUCTOR DEVICE

Semiconductor chips are arranged on an elongated substrate and encapsulated by an insulating encapsulation. Electrically conductive formations and electrically conductive plating lines are plated on the insulating encapsulation using, for example, Laser Direct Structuring (LDS) or Direct Copper Interconnect (DCI) material. The electrically conductive plating lines include first transverse plating lines as well as second plating lines branching out from the first plating lines towards the electrically conductive formations. A first partial cutting step is then performed to form grooves which remove the first plating lines. An insulating material is dispensed in the grooves to encapsulate the end portions of the second plating lines. A second cutting step median along the groove and through the elongate substrate is performed to produce singulated semiconductor devices (such as “die pad up” Quad-Flat No-lead (QFN) packages). End portions of the second plating lines are encapsulated by the insulating material.
