Interconnects Approach Tipping Point


As leading devices move to next generation nanosheets for logic, their interconnections are getting squeezed past the point where they can deliver low resistance pathways. The 1nm (10Å) node will have 20nm pitch and larger metal lines, but the interconnect stack already consumes a third of device power and accounts for 75% of the chip's RC delay. Changing this dynamic requires a superior co... » read more

Mechanical Stress In Semiconductor Development


With the semiconductor industry moving toward 3D DRAM, 3D logic architectures, and 1000+ layer 3D NAND stacks,1 mechanical failures may become more common. Due to the complexity of these structures, mechanical stress from materials processing has the potential to significantly impact yield. 3D processing techniques (etching, deposition, and related chemistries), as well as material property de... » read more

Memory Wall Problem Grows With LLMs


The growing imbalance between the amount of data that needs to be processed to train large language models (LLMs) and the inability to move that data back and forth fast enough between memories and processors has set off a massive global search for a better and more energy- and cost-efficient solution. Much of this is evident in the numbers. The GPU market is forecast to reach $190 billion in ... » read more

EUV’s Future Looks Even Brighter


The rapidly increasing demand for advanced-node chips to support everything-AI is putting pressure on the industry's ability to meet demand. The need for cutting-edge semiconductors is accelerating in applications ranging from hyperscale data centers powering large language models to edge AI in smartphones, IoT devices, and autonomous systems. But manufacturing those chips relies heavily on ... » read more

Developing Systems For Heterogeneous Integration: Insights From HiCONNECTS


The European semiconductor ecosystem continues to evolve, driven by the ambitions outlined in the EU Chips Act. With goals to strengthen Europe’s technological leadership and double its semiconductor manufacturing market share to 20% by 2030, collaboration across the value chain is imperative. Heterogeneous Integration for Connectivity and Sustainability (HiCONNECTS), a Horizon Europe-funde... » read more

Improving Uniformity And Linearity For All Masks


When it comes to mask quality, there are two vital measurements: uniformity and linearity. Uniformity measures the consistency of the size of mask features in all occurrences across the entire mask, because different instances of the same target size can vary in size due to manufacturing variation. Linearity measures how well different sizes of shapes on the manufactured mask match their target... » read more

Assembly Design Rules Slowly Emerge


Process design kits (PDKs) play an essential in ensuring that silicon technology can proceed from one generation to the next in a manner that design tools can keep up with. No such infrastructure has been needed for packaging in the past, but that's beginning to change with advanced packages. Heterogeneous assemblies are still ramping up, but their benefits are attracting new designs. “Chi... » read more

An Innovative Hybrid Cleaning Approach For Contaminant Removal in Semiconductor Packaging


The growing demand for power semiconductors, which control large currents and voltages, has resulted in their widespread use in various electronic devices, including electric vehicles (EVs). The requirement for greater performance and smaller devices has led to increased operating temperatures for these power semiconductors. This rise in temperature poses a challenge as it often leads to delami... » read more
