Power Delivery Challenges For AI Chips


As artificial intelligence (AI) workloads grow larger and more complex, the various processing elements being developed to process all that data are demanding unprecedented levels of power. But delivering this power efficiently and reliably, without degrading signal integrity or introducing thermal bottlenecks, has created some of the toughest design and manufacturing challenges in semiconducto... » read more

Front-End Technologies Are The New Back-End Tools: Using Picosecond Ultrasonics Technology For AI Packages, Part 1


If you are a part of the semiconductor industry or simply someone interested in the field, you have likely heard what has become a common refrain: the back-end of the process is becoming more like the front-end of the process. In other words, the technologies that were once exclusively deployed in the first part of the process are being used to meet the increasingly stringent requirements of ad... » read more

Big Changes In Medical Electronics


Medical devices are becoming more capable, more complicated, and more deployable in the field rather than in a hospital or a doctor's office. But getting these purpose-built devices into the hands of consumers requires a whole bunch of new challenges, from safeguarding fragile on-board chemistries that can be destroyed by existing chip manufacturing and packaging processes to ensuring the mater... » read more

Co-Packaged Optics Reaches Power Efficiency Tipping Point


Commercialization has started for network switches based on co-packaged optics (CPO), which are capable of routing signals at terabits per second speeds, but manufacturing challenges remain regarding fiber-to-photonic IC alignment, thermal mitigation, and optical testing strategies. By moving the optical-to-electronic data conversion as close as possible to the GPU/ASIC switch in data center... » read more

Thermo-Mechanical Stress On Active Chiplets In A 3D-IC Heterogeneous Package Assembly


The move to heterogeneous multi-chip/chiplet products improves yield, performance and modularity while reducing power and overall product footprint. However, this shift to heterogeneous assembly also introduces new complexities that can influence chip warpage and circuit behavior due to thermo-mechanical stress impacts. In heterogeneous 3D IC architectures, the interaction between the chips ... » read more
