Process for fabricating circuit components in matrix batches
11521862 · 2022-12-06 · ·

A process for batch fabrication of circuit components is disclosed via simultaneously packaging multiple circuit component dice in a matrix. Each die has electrodes on its tops and bottom surfaces to be electrically connected to a corresponding electrical terminal of the circuit component it's packaged in. For each circuit component in the matrix, the process forms preparative electrical terminals on a copper substrate. Component dice are pick-and-placed onto the copper substrate with their bottom electrodes landing on corresponding preparative electrical terminal. Horizontal conductor plates are then placed horizontally on top of the circuit component dice, with bottom surface at one end of each plate landing on the dice's top electrode. An opening is formed at the opposite end and has vertical conductive surfaces. A vertical conductor block is placed into the opening and lands on the preparative electrical terminal, and the opening's vertical conductive surfaces facing the top end side surface of the vertical block. A thermal reflow then simultaneously melts pre-applied soldering material so that each circuit component die and its vertical conductor block are soldered to the copper substrate below and its horizontal conductor plate above.

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.

A lead frame for an integrated electronic device includes a die pad made of a first metallic material. A top coating layer formed by a second metallic material is arranged on a top surface of the die pad. The second metallic material has an oxidation rate lower than the first metallic material. The top coating layer leaves exposed a number of corner portions of the top surface of the die pad. A subsequent heating operation, for example occurring in connection with wirebonding, causes an oxidized layer to form on the corner portions of the top surface of the die pad at a position in contact with the top coating layer.
