Abstract:
A package substrate may include an insulating substrate, internal circuits and a warpage-suppressing member. The insulating substrate may have a plurality of mount regions in which semiconductor chips may be mounted, and a peripheral region. The internal circuits may be arranged in the mount regions. The warpage-suppressing member is different from the semiconductor chips and may be arranged in at least one of the mount regions to suppress a warpage of the insulating substrate. Thus, warpage of the package substrate may be suppressed during a reflow process.
Abstract:
A semiconductor package includes a substrate having a vent hole defined therein. Semiconductor chips are mounted on an upper surface of the substrate. Chip connection terminals are disposed between the substrate and the semiconductor chips. Substrate connection terminals are disposed on a lower surface of the substrate. A plated layer includes a vertical heat-dissipation layer on an inner wall of the vent hole, a first heat-dissipation layer on the upper surface of the substrate and connected to at least one of the chip connection terminals and a second heat-dissipation layer on the lower surface of the substrate and connected to at least one of the substrate connection terminals. An encapsulant covers the upper surface of the substrate, the chip connection terminals, and the semiconductor chips, and fills a space between the semiconductor chips and the substrate. The encapsulant is on the plated layer and fills the vent hole.
Abstract:
An example embodiment relates to a semiconductor device including a semiconductor package in which a semiconductor chip is mounted on the package substrate. The semiconductor package may include a temperature measurement device and a temperature control circuit. The temperature measurement device may measure a temperature of the semiconductor package. The temperature control circuit may change an operation speed of the semiconductor package on the basis of the temperature of the semiconductor package measured by the temperature measurement device.
