Samsung Electronics Co. has announced an aggressive five-year plan to tempt U.S. chip buyers with more advanced technology, aiming to produce transistors that are just 1.4 nanometers wide by 2027.

The company’s contract chip-manufacturing unit — known as a foundry — is looking to triple its revenue by that year from the 2021 level, Senior Vice President Moonsoo Kang said at a briefing Monday in San Jose, California. To get there, the business will need to make several technological leaps and further inroads into the U.S. market for outsourced chips.

Samsung shares were up as much as 4.1% in Seoul on Tuesday, after falling by almost a third this year with rising costs and a downturn in the memory market.
