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.

Warmer temps increase rattlesnake risks: Arizona Game and Fish


Officials with the Arizona Game and Fish Department said unseasonably warm temperatures in the state will increase risks for rattlesnake encounters.

What they’re saying:

In a statement released on Feb. 27, the agency said while rattlesnakes are most active in desert areas from March through October, they “may appear earlier in the year as warming temperatures bring them out of winter hibernation.”

“During the spring, it’s common for rattlesnakes to be out during daylight hours,” read a portion of the statement. “As the days become increasingly hot, rattlesnakes tend to move around more at night.”

Officials said there are things people can do to keep themselves safe, including:

  • Step back and let a rattlesnake move away if you see one on a trail
  • Be mindful of where you place your feet and hands, because rattlesnakes can easily blend in with their surroundings
  • Carry a flashlight at night, especially on warmer nights when rattlesnakes can be most active
  • Clean up yard debris and reduce standing water near homes, in order to avoid attracting rattlesnakes
  • Stay on marked trails, as rattlesnakes encounters are more likely to occur when a person leaves a marked trail

Game and Fish officials said people should do the following if someone was bitten by a rattlesnake:

  • Remain calm
  • Reassure the victim
  • Call 911 and seek medical attention without delay
  • Remove all jewelry and watches from the affected area
  • Immobilize the extremity, and keep it below the heart
  • Decrease total body activity, as feasible

Former Arizona town employee sentenced in COVID-19 relief, embezzlement case


PARKER, AZ (AZFamily) — A former employee of a western Arizona town has learned her fate after being convicted in connection with COVID-19 relief fraud and embezzlement.

Arizona Attorney General Kris Mayes said Thursday that Jennifer Elizabeth Alcaida, 50, a former office specialist for the Town of Parker, was sentenced by a Mohave County Superior Court judge to three and a half years in prison.

According to court records, between July and Sept. 2021, Alcaida took a total of $173,295.54 by writing unauthorized checks from town accounts, keeping cash she was required to deposit, and making personal purchases on a town-issued credit card.

Records also show she received more than $20,000 from the federal Paycheck Protection Program through the U.S. Small Business Administration after claiming the funds were needed to cover payroll for a personal business that did not exist.

Alcaida pleaded guilty Jan. 6 to felony charges of fraudulent schemes and theft. After her prison term, she will serve seven years of probation and has been ordered to pay $194,128.54 in restitution.

“This case is a clear example of someone who abused the public’s trust for personal gain,” Mayes said in a written statement. “Arizonans deserve to know that those who steal from their communities will be held accountable, and this sentence reflects exactly that.”
