Semiconductor device formed dam and mounting structure of the semiconductor device

摘要

A flip chip device may have a semiconductor chip with an active surface on which chip pads and a protective layer may be provided. Solder bumps may be provided on the active surface and electrically connected to the chip pads. And a solder bar may be provided on a portion of the protective layer. The solder bar may disperse thermal stress produced in the solder bumps. A metal core may be embedded within the solder bar. The flip chip device may be mounted on and flip-chip bonded to a substrate. The substrate may have land pads to which the solder bumps and the solder bar may be mechanically joined. The solder bar increases a joint area between the flip chip device and the substrate and reinforces solder connections therebetween.
