Memory spot price rally that had started in September slowed down in October amid growing COVID-19 worries and sluggish demand from the data center sector. Despite a pick-up in demand for consumer electronics applications, the overall memory demand remains slow. But the automotive sector is gaining momentum, as carmakers replenish their inventory. Demand for automotive chips and components is expected to remain strong till first-quarter 2021. For TSMC, clients are scrambling for foundry supply of not only advanced node capacity, but also of mature processes. TSMC has seen 28nm capacity utilization reach almost 100%, thanks to orders switched from China's SMIC.
