142266 - Thermal Management of 3d High-Power Chip Stacks to Enable Advanced Semiconductor Packaging
Abstract:
Current global trends in the generation, transmission, and processing of data rest on the continued advances in the functionality of semiconductor devices that have thermally constrained performance and efficiency. In particular, vertical stacking of semiconductor dies holds promise to significantly enhance computational performance for applications demanding high bandwidth, enabled by advances in chip manufacturing and assembly. However, the ability to effectively dissipating heat from within these 3D high-power chip stacks remains a formidable obstacle to their broader adoption. This talk will review several examples of pioneering research that has led to breakthrough strategies for advanced semiconductor packaging in the Cooling Technologies Research Center (CTRC) at Purdue University and the SRC Center for Heterogeneous Integration Research in Packaging (CHIRP). These include a variety of embedded cooling technologies specifically designed for semiconductor packages, such as passive novel heat pipes capable of extracting high powers from a 100-micron gap in a die stack, co-design capabilities that can simultaneously address both power delivery and thermal regulation in advanced packaging, and new metrology for characterization of deeply buried thermal interfaces. These team efforts are dedicated to improving device reliability and performance by optimizing heat dissipation in compact electronic packages, highlighting the indispensable role of thermal management in diverse applications and environments.
