How does the collaboration with MediaTek contribute to the system’s power efficiency and performance?
TSMC’s Price Hikes Send Apple A-series Wafer Costs Soaring To US$18,000 Per Wafer
Apple’s A-series processors have seen remarkable evolution from the A7 in 2013 to the A18 Pro in 2024, with a significant increase in both transistor count and manufacturing costs. As transistor density increases, the cost per wafer for advanced nodes, such as the 3nm A17 and A18 chips, has skyrocketed from $5,000 to $18,000, reflecting a 300% price increase. Despite the slowing rate of transistor density growth, the complexity of new manufacturing processes and high R&D costs have contributed to sharp rises in production expenses. What impact will the rising costs of advanced process technology have on Apple’s pricing strategy for future devices? How might TSMC’s price adjustments affect competition among semiconductor companies? What challenges might TSMC face with its 2nm process capacity in meeting demand from major customers like Apple, Nvidia, and Qualcomm?
TSMC’s Wafer Manufacturing 2.0 Reshapes Advanced Packaging Market
In July 2024, TSMC launched “Wafer Manufacturing 2.0,” marking a significant shift in the advanced packaging industry by integrating packaging, testing, and photomask production into its offerings. This move challenges the traditional roles of OSAT (outsourced semiconductor assembly and test) firms and reshapes the competitive landscape as wafer foundries like TSMC, Samsung, and Intel expand into packaging. As advanced packaging technologies such as 2.5D/3D packaging gain traction, Chinese manufacturers like JCET and Tongfu Microelectronics are ramping up investments to compete with global leaders. How will TSMC’s integration of packaging and testing affect the traditional roles of OSAT providers? What challenges will traditional OSAT companies face as wafer foundries expand into advanced packaging? How might the rise of Chinese manufacturers in advanced packaging influence the global market?
China’s Export Ban To Push Antimony Prices To New Highs
Following China’s export ban on critical minerals like gallium, germanium, and antimony, prices of antimony have surged to record levels, currently trading between $39,500-40,000 per metric ton. The 250% increase in prices in 2024 reflects the growing trade tensions and a global supply shortage, with traders predicting prices could climb even higher. China, which produced nearly 50% of the global supply of antimony in 2024, is consolidating mineral production internally, leaving the U.S. and other buyers scrambling to diversify their supply chains. As the U.S. seeks alternative sources, the potential for further export bans by China on other critical minerals looms large What impact will China’s export bans have on the U.S. supply of antimony and other critical minerals? How might the growing reliance on non-Chinese suppliers affect global pricing and market dynamics? What minerals could be targeted next by China in its strategy to consolidate mineral production internally?

When Will AIoT Outsmart Humans, And How Will We Know?
AI and the Internet of Things (IoT) are rapidly advancing, with the potential to revolutionize sectors like predictive and prescriptive maintenance. However, the growing reliance on AI-driven systems raises questions about how much trust we should place in these technologies, particularly when it comes to critical decisions in industries like manufacturing. For example, the “butterfly effect” in AI highlights the unpredictable impact of seemingly small changes in data, which could lead to significant consequences that humans may not immediately recognize. As AI systems suggest actions, such as maintenance shutdowns, will human operators be willing to follow through, or will they prioritize traditional decision-making processes? At what point should human operators trust AI’s recommendations over their own judgment? How can industries balance the benefits of AI with the need for human oversight? What steps can be taken to ensure that AI systems continue to evolve and adapt effectively?
Could AI Help Predict The Next Pandemic?
The recent COVID-19 pandemic highlighted the need for effective tools to predict and control the spread of infectious diseases, and AI is emerging as a crucial tool in this effort. AI has already proven useful in outbreak detection, virus tracking, and resource management, and it could play a key role in preventing future pandemics. However, challenges such as data privacy and prediction accuracy remain. Can AI help predict and prepare for new viral strains? How can AI improve disease surveillance during crises? What limitations of AI need to be addressed in pandemic preparedness?
