Publication number: 20240249955Abstract: An multi-die semiconductor device disclosed herein includes a metallic leadframe with a central die pad encircled by electrically-conductive leads. Mounted on the die pad are two semiconductor dice, each with dedicated bonding pads on the surfaces facing away from the die pad. A layer of laser-activatable material is precisely molded over the dice and the leadframe. This layer forms a network of laser-activated lines: the first subset establishes electrical connections between the dice bonding pads and the leadframe leads, while the second subset interconnects the bonding pads of the first die to those of the second. There are two distinct metallic layers; the lower one, directly on the laser-activated lines, is formed of electroless-plated material, and the upper one, enhancing the structure, is formed of electroplated material, thus providing robust and reliable interconnections within the device.Type: ApplicationFiled: April 2, 2024Publication date: July 25, 2024Applicant: STMicroelectronics S.r.l.Inventor: Paolo CREMA
