Title: Chip heat dissipation structure, chip structure, circuit board and supercomputing device
Inventor: SU DAN
IPC: H01L33/64
Filed: 2018-11-23
Abstract: Embodiments of the present application relate to a chip heat dissipation structure, a chip structure, a circuit board and a supercomputing device. The chip heat dissipation structure comprises: a plating covering a wafer of a chip, wherein the plating comprises a first metal layer, a second metal layer and a third metal layer. The three metal layers are added on the top of the chip by way of physical sputtering, so that a heat dissipater can be welded onto the metal layers via a solder layer, thereby fixing the heat dissipater to the top of the chip. The main component of the solder layer is metallic tin, and the metal layers, with respect to an epoxy resin adhesive material surface-mounted to a traditional heat dissipater, have a higher heat conductivity coefficient, thereby solving the problem of a heat dissipation bottleneck of an adhesive material in the chip. The heat dissipation effect of the chip can be improved, and the chip is prevented from being damaged by a large amount of heat.
