Samsung Electronics Co. is considering a second location in Texas for its envisioned $17 billion U.S. semiconductor plant, a signature project that could address U.S. concerns about chip security while expanding its own capabilities.

The Korean company is exploring another 6 million square-foot site apart from a previously disclosed expansion of its Austin base, according to documents filed with local government. If it goes ahead, Samsung will begin construction at the Williamson Country site around the first quarter of 2022, with targeted production by the final three months of 2024.

Samsung is weighing options for an advanced chipmaking plant in the U.S., in hopes of winning more American clients and narrowing the gap with industry leader Taiwan Semiconductor Manufacturing Co. The company had been in discussions to locate a facility in Austin, Texas, capable of fabricating chips as advanced as 3 nanometers, people familiar with the matter have said.

Dubbed Project Silicon Silver, that plan included adding about 7 million square feet of new space to the Austin campus, where the company has had operations for decades.
