摘要:
The substrate with through silicon plugs (or vias) described above removes the need for conductive bumps. The process flow is very simple and cost efficient. The structures described combines the separate TSV, redistribution layer, and conductive bump structures into a single structure. By combining the separate structures, a low resistance electrical connection with high heat dissipation capability is created. In addition, the substrate with through silicon plugs (or vias, or trenches) also allows multiple chips to be packaged together. A through silicon trench can surround the one or more chips to provide protection against copper diffusing to neighboring devices during manufacturing. In addition, multiple chips with similar or different functions can be integrated on the TSV substrate. Through silicon plugs with different patterns can be used under a semiconductor chip(s) to improve heat dissipation and to resolve manufacturing concerns.

The package substrates with through silicon plugs (or vias) described above provide lateral and vertical heat dissipation pathways for semiconductor chips that require thermal management. Designs of through silicon plugs (TSPs) with high duty ratios can most effectively provide heat dissipation. TSP designs with patterns of double-sided combs can provide high duty ratios, such as equal to or greater than 50%. Package substrates with high duty ratios are useful for semiconductor chips that generate large amount of heat. An example of such semiconductor chip is a light-emitting diode (LED) chip.
