Seoul,  Samsung Electronics is expected to showcase one of its most advanced chipmaking technologies to US President Joe Biden when he visits its Pyeongtaek campus this week, sources said on Thursday.

Biden is set to arrive in Seoul Friday on his first visit to the country since taking office, and only 10 days after South Korea's new President Yoon Suk-yeol took office.

His three-day visit to South Korea will start with a tour of Samsung's Pyeongtaek complex, the world's largest semiconductor facility, located some 70 kms south of Seoul, reports Yonhap news agency.

Samsung Electronics Vice Chairman Lee Jae-yong is said to provide a personal tour of the massive complex.

The company is expected to show its next-generation 3-nanometer (nm) semiconductor built on the Gate-All-Around (GAA) technology, which Samsung will mass produce within the next couple of months.

"Samsung could show a 3-nm chip to Biden to emphasize its foundry prowess over Taiwan's TSMC," an official with the knowledge of Samsung's advanced chip technology said.

The GAA process allows for an up to 35-percent decrease in size while providing 30 percent higher performance, or 50 percent lower power consumption, compared to the 5nm process, according to Samsung.

Samsung, the world's largest memory chip maker and second largest foundry player, has said its 2nm process node was in the early stages of development with mass production in 2025.

TSMC, the world's largest contract chip manufacturer, and Samsung have been in fierce competition to outperform each other by bringing the 3-nm chips to the mass market.

According to industry tracker TrendForce, TSMC took up 52.1 per cent of the global foundry market, followed by Samsung with 18.3 per cent, in the fourth quarter of last year.
