NSF SBIR Phase II grant on LM-Elastomer TIMs for high performance computing

Recent advances in semiconductor manufacturing have led to increases in computational performance at the cost of increasing power densities and attendant thermal management issues. One key to solving these challenges is to reduce the thermal resistance of interfaces in the electronics packaging stack, using advanced thermal interface materials (TIMs). However, existing TIMs often suffer from reliability issues and introduce costly manufacturing complexities. In this SBIR Phase II project, Arieca will build upon our proprietary liquid metal embedded elastomer (LMEE) composite architecture to develop an “ultimate TIM” to imrpvoe reliability and reduce cost of thermal management at scale.

This LMEE-based TIM will outperform existing TIMs by combining the superior thermal resistance of metal-based solid TIMs (S-TIMs) with the mechanical reliability of polymer-based TIMs (P-TIMs) and the high volume manufacturing compatibility of thermal greases. Our strategy in Phase II is to synthesize an LMEE-based TIM that forms a robust bond between the surfaces of the semiconductor chip and surrounding enclosure, maintains a controlled “bond line thickness” (BLT) between the chip and enclosure, and has the necessary rheology for syringe-based dispensing using both augers and pneumatic dispensers. This will involve a comprehensive technical plan that includes materials synthesis, performance characterization, in-package evaluation, and scale-up to high volume production. We look forward to delivering this ultimate TIM to our customers in the integrated device manufacturers (IDMs) and the outsourced semiconductor assembly and testing (OSAT) industry.

NSF SBIR Grant for LM-Elastomer TIMs in computing

Thermal management issues in the semiconductor industry are driven by a sharp increase in power densities. To resolve these issues, many attempts are being investigated in device packaging to extract the heat generated away and maintain the functionality of the device. Existing thermal interface materials (TIMs) play an important role in transferring the heat efficiently but suffer from challenges associated with interfacial contact thermal resistance, optimized distribution of TIM over the die surface, pump-out and delamination.

This SBIR project supports Arieca’s efforts to create a TIM version of LMEEs, which we call TIMbberTM, to overcome these challenges. Specific efforts will focus on refining the formulation and fabrication to meet customer specifications. This includes improvement of the TIMbber material composition, development of a scalable manufacturing process, and characterization of materials properties for TIM applications.
