Samsung today announced that it has opened new V1 semiconductor fabrication line in Hwaseong, Korea, dedicated to the extreme ultraviolet (EUV) lithography technology and produces chips using process node of 7 nanometer (nm) and below. It started building it back in February 2018, and began test wafer production in the second half of 2019.
The V1 line is currently producing state-of-the-art mobile chips with 7 and 6nm process technology, and the company said that it will continue to adopt finer circuitry up to the 3nm process node.
Samsung already said that the cumulative total investment in the V1 line will reach US$6 billion by the end of 2020, and the total capacity from 7nm and below process node is expected to triple from that of 2019. Together with the S3 line, the V1 line is expected to play a pivotal role in responding to fast-growing global market demand for single-digit node foundry technologies.
“As semiconductor geometries grow smaller, the adoption of EUV lithography technology has become increasingly important, as it enables scaling down of complex patterns on wafers and provides an optimal choice for next-generation applications such as 5G, AI, and Automotive,” said Samsung.
With the V1 line in operation, Samsung now has a total of six foundry production lines in South Korea and the United States, including five 12-inch lines and one 8-inch line.
| Name | Nodes | Location | Wafer Size |
| 6-Line | 180~65nm | Giheung, Korea | 8-inch |
| S1-Line | 65~8nm | ||
| S2-Line | 65~11nm | Austin, USA | 12-inch |
| S3-Line | 10nm~ | ||
| S4-Line | 65nm~ | Hwaseong, Korea | |
| V1-Line | 7nm~ |
First products from the production line will be delivered to customers in the first quarter of 2020.
Commenting on the same, Dr. ES Jung, President and Head of Foundry Business at Samsung Electronics, said:
Along with technology leadership and design infrastructure, manufacturing excellence is one of the most important elements of the foundry business. As we ramp up production, the V1 line will enhance our ability to respond to market demand and expand opportunities to support our customers.
