AI Technical Summary

Problems solved by technology

Thereby, the heat energy generated by the chip can be transferred to the substrate through the protruding part, and then reach a heat sink; however, the electrical contacts are not easy to be arranged on the insulating layer, and it is difficult to electrically connect with the next layer assembly, and Cannot provide multi-layer routing

[0019] Significant disadvantages of known packages and thermal pads

For example, electrical insulating materials with low thermal conductivity, such as epoxy resins, limit heat dissipation; however, electrical insulating materials with higher thermal conductivity, such as epoxy resins filled with ceramic or silicon carbide, have low adhesion and Due to the high cost of mass production, the electrical insulating material may delaminate due to heat during the production process or in the early stage of operation

If the substrate is a single-layer circuit system, the routing capability is limited, but if the substrate is a multi-layer circuit system, its excessively thick dielectric layer will reduce the heat dissipation effect

In addition, the previous technology still has problems such as insufficient performance of the heat sink, too large volume, or difficult thermal connection to the next layer of assembly, and the manufacturing process of the previous technology is not suitable for low-cost mass production.

[0020] In view of the various development situations and related limitations of the existing high-power semiconductor component packages and heat-conducting plates, it is generally impossible to meet the requirements of the industry for a cost-effective, reliable performance, and suitable for mass production. , multi-function, flexible adjustment of signal routing and excellent heat dissipation semiconductor chipset
