Thermal Management Implications For Heterogeneous Integrated Packaging


As the semiconductor industry reaches lower process nodes, silicon designers struggle to have Moore's Law produce the results achieved in earlier generations. Increasing the die size in a monolithic system on chip (SoC) designs is no longer economically viable. The breakdown of monolithic SoCs into specialized chips, referred to as chiplets, presents significant benefits in terms of cost, yield... » read more

Application and Verification of Effective Heat Spreading Angles on a Multi-Layer Thermal Design


Abstract: "When designing converters, the average junction temperature of the semiconductor is a frequently required estimate. Its analytical calculation requires the total thermal resistance of the cooling arrangement. Unfortunately, due to the complexity of the heat dissipation processes, an estimate of the thermal resistance is usually associated with low accuracy. To significantly improve ... » read more

High Thermal Die-Attach Paste Development For Analog Circuits


In recent years, various die attach (DA) materials have been developed to cope with the higher power dissipation requirements of semiconductor devices. DA materials based on metals such as solder or sintered silver (Ag) are used for very high heat generating power devices. While they show outstanding thermal performance, the mechanical properties of these materials are less than ideal. This lim... » read more

Thermal Interface Materials: The Unknown Entity?


Thermal interface materials (TIMs) are becoming more important in all application areas and between different component parts. Any semiconductor, ranging from LEDs to high-power electronics, is becoming smaller, yet producing more power. In many ways the physical design limits have been reached for packaging, allowing entire components to have a total thermal resistance of less than 0.1 K/W. Ho... » read more
