Samsung's huge investment plan seen unlikely to unseat TSMC.

While the US$356 billion investment may drive the growth of Samsung's semiconductor business in the future, the South Korean conglomerate still lags behind TSMC in terms of manufacturing technology and customer relations.

TSMC remains dominant in areas such as manufacturing technology and yields, and it continues to outpace its major competitors Samsung and U.S.-based $Intel (INTC.US)$ . in terms of advanced semiconductor technology development.

TSM has already secured orders for its 3 nm chips and is scheduled to start mass production later this year, while Samsung is still struggling with 3nm manufacturing issues that could impact its ability to mass-produce chips and devices on that process.
