TSMC’s Arizona Fab 21 is already making 4nm chips


TSMC has started producing chips at its Fab 21 near Phoenix, Arizona, using its 4nm-class process technology, Commerce Secretary Gina Raimondo told Reuters. This marks the first time such a cutting-edge production node has been manufactured in the United States. The confirmation from a high-ranking official comes months after the first unofficial information emerged that the fab was mass-producing chips for Apple.

“For the first time ever in our country’s history, we are making leading-edge 4nm chips on American soil, American workers — on par in yield and quality with Taiwan,” Raimondo told Reuters.

According to unofficial information, TSMC’s Fab 21 in Arizona is manufacturing at least three processor models: the A16 Bionic system-on-chip used in Apple’s iPhone 15 and iPhone 15 Plus; the main processor of Apple’s S9 system-in-package for smartwatches, which has two 64-bit cores and a quad-core neural engine; and an AMD Ryzen 9000-series CPU. These chips are produced on TSMC’s 4nm-class—N4 and N4P—process technologies.

The TSMC Arizona project is instrumental to the U.S. goal of producing 20% of the world’s most advanced logic chips by 2030, which the Biden administration set a few years ago before enacting the CHIPS and Science Act. TSMC’s Fab 21 in Arizona produces chips for American companies in volumes (it is rumored that currently, the facility’s production capacity is around 10,000 wafer starts per month), clear evidence that the initiative works.

Under the CHIPS and Science Act, the U.S. Commerce Department provided TSMC with $6.6 billion in grants and up to $5 billion in loan guarantees. The Fab 21 site will require funding of about $65 billion to include three fab modules that are set to be constructed and launched online by the end of the decade.

The first Fab 21 phase 1 module will officially start mass production using 4nm and 5nm-class process technologies. The next Fab 21 phase 2 is expected to follow in 2028 with 3nm-class process technologies. By the decade’s end, TSMC expects to build its Fab 21 phase 3, which will produce chips on 2nm-class and 1.6nm-class nodes and their variations with backside power delivery.

Final Four: Yaxel Lendeborg vows to play vs. UConn after finishing win over Arizona with MCL, ankle injuries — ‘I’m gonna play unless I can’t walk’


Michigan All-American Yaxel Lendeborg returned to Saturday’s Final Four win over Arizona after suffering knee and ankle injuries and vowed after the game to play in Monday’s NCAA title game against UConn.

Lendeborg confirmed postgame that he sprained his left MCL and injured his ankle on a fall in the first half. He missed most of the first half, but returned to play briefly in the second half of Michigan’s runaway win.

Arizona’s Koa Peat has won at all levels, Michigan next in Final Four

Arizona’s Koa Peat has won at all levels, Michigan next in Final Four

INDIANAPOLIS – Chandler native Koa Peat has won a lot of big games.

He led Perry High School to four straight state high school championships. He’s been part of gold-medal-winning entries for Team USA. And he’s a star freshman on the No. 1 University of Arizona team, which is on the precipice of the school’s first national championship since 1997.

It should have been hard for him to come up with an answer when asked the last time he actually “lost” a big game, but he did come up with one.

He singled out Arizona’s loss to then-No. 9 Kansas at Phog Allen Fieldhouse in February. That was one of just two games the Wildcats dropped this season. It says a lot that it was the worst loss he can remember.

Peat and the Wildcats (36-2) will square off against Michigan (35-3) in the second of two NCAA semifinals on Saturday, April 4 at Lucas Oil Stadium, home of the NFL’s Indianapolis Colts. The game is scheduled to tip off at roughly 5:50 p.m. MST, and will be televised on TNT, TBS and truTV.

The first Final Four game will pit Illinois against Connecticut at 4 p.m. and will be televised on TBS and truTV. The winners will compete for the national championship on Monday, April 6.

Arizona has won 13 straight games since back-to-back losses to Kansas and Texas Tech in February. Peat has hardly looked the part of a freshman.

“They call him Mr. Arizona,” said Wildcats’ coach Tommy Lloyd, who agreed to a contract extension on the eve of the team’s semifinal showdown. “Koa is special, and I know you guys hear it, but you got to hear it again. Four state championships at the same high school. Didn’t go to a prep school. Four gold medals with USA Basketball. No one in FIBA history has ever done that. And helped lead Arizona to a Final Four.”

At 6-foot-8, 235 pounds, Peat hardly looks like a freshman physically. He doesn’t play like one either.

Peat is averaging 14.1 points, 5.5 rebounds, and 2.7 assists. That might sound pedestrian compared to some athletes who have put up video-game-like offensive numbers. But this Arizona team is balanced offensively, with all five starters averaging double figures.

Peat has been at his best in the big moments. He was named the most outstanding player in the West Region, scoring 21 points against Arkansas in the Sweet 16 win and 20 against Purdue in the Elite Eight victory, which earned the Wildcats a berth in Indianapolis.

He came onto the scene with a bang, scoring a season-high 30 against defending national champion Florida on Nov. 3.

While that game was a long time ago, it was a good indicator that the Wildcats could go the distance because they beat a team like Florida, which is similar to Michigan with size in the front court.

“We always watch our good highlights, so just seeing those (against Florida) definitely gives us confidence for sure,” Peat said.

Michigan coach Dusty May said it takes a certain kind of player to be able to compete at this level as a true freshman, and Peat fits the bill, as does Brayden Burries.

“When we were at Florida (Atlantic) we used to talk about how there are certain prerequisites to be able to play as a freshman at a Power Five level,” May said. “And one of those prerequisites was playing USA Basketball because of the amount of intensity that it takes to compete during the trials, during the practices and also the games and also the sacrifice it takes because you’re playing with 11 of the best players in our country and you have to sacrifice so much just to play.”

Genes and a competitive drive probably help too. Peat grew up in a house full of athletes as the youngest of seven siblings, all of whom played football or basketball. His brother, Andrus Peat, has been in the NFL for 10 years and currently plays for the Pittsburgh Steelers. His father, Todd, played for four teams in the NFL, most notably the Cardinals.

“It’s been a blessing to have great people like that around me, a family as I have with so many athletes who played Division I sports,” Peat said, on the eve of the national semifinal. “I would say I am the most competitive just because their competitiveness was passed down to me, seeing how good they were and what it took to compete.”

Lloyd has been impressed, although not necessarily surprised, with how Peat has performed as well as the way he has remained grounded.

“The dude, he’s amazing. His ability to perform the way he did in these moments, you know, he’s been in a lot of them,” Lloyd said. “I told our guys, don’t make too much out of this. It’s like a state championship game. You guys have all played in them. Or a gold medal game or whatever. Let’s just find a way to win the game. Don’t make it more than it is.”
