“Three nanometers, TSMC already has a plan, but it’s not finalized yet. It’s almost done—at the same location in Arizona, phase two. 5 nanometers is phase one, 3 nanometers is phase two,” Chang said at a press conference in Taipei with Reuters news agency.
In November 2020, the Taiwanese giant received US permission to build a $12 billion chip factory in Phoenix, Arizona. TSMC’s Fab 18, located in Tainan City, Taiwan, is the main 3nm manufacturing base.
What is TSMC’s 3nm technology?
TSMC says that its 3nm (N3) technology is a full step up from the 5nm (N5) technology. N3 technology will provide up to 70% logic density increase, up to 15% speed improvement at the same capacity, and up to 30% power reduction at the same speed compared to N5 technology.
“N3 technology will provide complete platform support for both mobile and HPC applications,” the company said on its website. The company also says that it is aiming to start mass production in the second half of 2022.
Recently, Qualcomm has launched the SoC Snapdragon 8 Gen 2 chip using TSMC’s 4nm process. This means that processors based on the 3nm architecture will be more efficient than these.
Depends on Taiwan for chips
As reported by The Wall Street Journal, TSMC manufactures nearly all of the world’s most complex chips. This dominant position has made the most of the fact that the technology giants are so dependent on the company. Recently, China has increased military pressure to assert its sovereignty claims on the island.
Unnamed, Chang said many countries have asked him if TSMC can come to their countries to produce chips. “There are a lot of people who are envious, jealous of Taiwan’s excellent chip production. So there are also a lot of people for various reasons, whether it’s for national security or to make money, to desire. produce more chips in their country,” he said. speak.
TSMC has US government support
Bloomberg quoted Chang as saying that US Vice President Kamala Harris welcomed TSMC’s decision to open a second factory in Arizona. She reiterated the government’s stance to help Taiwan.
TSMC is holding an “instrument” ceremony in Arizona on December 6 and US Secretary of Commerce Gina Raimondo will attend the event, according to the report. Our President Joe Biden was also invited.
