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.
