3D Printed Chip Packages Could Supercharge Semiconductor Manufacturing
AUSTIN, Texas — Engineers at The University of Texas at Austin are leading an academic and industry all-star team that aims to revolutionize the production of semiconductor chips with a new 3D printing method. The new approach, which the researchers are calling Holographic Metasurface Nano-Lithography (HMNL), aims for faster, more efficient and environmentally friendly production of advanced electronics.
HMNL has applications ranging from smartphones to robotics to aerospace. It can create designs that were previously impossible, such as 3D printed capacitors, which store energy in electronic devices, or electronic packages that fit into unconventional spaces. For example, it would make it possible to embed artificial intelligence in customized configurations to fit the specifications of robots or rockets.
“Our goal is to fundamentally change how electronics are packaged and manufactured,” said Michael Cullinan, an associate professor in the Cockrell School of Engineering’s Walker Department of Mechanical Engineering, who is leading the team. “With HMNL, we can create complex, multimaterial structures in a single step, reducing production time from months to days.”
The team, comprising researchers at the University of Utah, Applied Materials, Bright Silicon Technologies, Electroninks, Northrop Grumman, NXP Semiconductors and Texas Microsintering, has received a $14.5 million grant from the Defense Advanced Research Projects Agency (DARPA) to pursue this work.
Electronics manufacturing today is a complex, time-consuming process that involves layering materials one step at a time. This approach not only limits design flexibility but also generates significant material waste. HMNL offers a faster, more sustainable alternative.
The key to this technical leap lies in metasurfaces, which are ultra-thin optical masks capable of encoding high-density information. When exposed to light, these metasurfaces create holograms that enable the simultaneous patterning of a hybrid resin made of metal and polymer into intricate 3D structures. The process is so precise that it can achieve resolutions smaller than the width of a human hair.
Additionally, by eliminating multiple production steps and reducing material waste, the process minimizes the environmental footprint of industrial activities. The increased speed will make it easier to develop unique prototypes.
The researchers created four prototypes as part of this project for a variety of applications:
- Commercial electronics: A fan-out module for consumer devices, showcasing faster production and improved design flexibility.
- Defense systems: Advanced prototypes for high-frequency communication and reconfigurable electronics.
- Nonplanar designs: Electronics packages that fit into challenging spaces.
- Active packages: Structures that serve mechanical and electrical functions, such as precise beam-pointing systems for optical applications.
“This isn’t just about making electronics faster or cheaper; it’s about unlocking new possibilities,” said Cullinan.
The researchers plan to commercialize the technology through Texas Microsintering Inc., a startup founded by Cullinan.

Athena the owl: 2nd owlet discovered to be alive
AUSTIN, Texas – It was initially believed that both of Athena the owl’s owlets at the Lady Bird Johnson Wildflower Center had died, but officials reported some hopeful news.
What we know:
On April 19, the wildflower center had posted that both of Athena’s owlets had not survived after they had been born on April 9 and April 11.
The first owlet died on April 17 and the second owlet was reported to have died overnight on April 18.
Athena was not seen at the nest and was not spotted in nearby trees.
The wildflower center continued to monitor the nest and on April 20, the second owlet was found to be alive and showing signs of movement.
In coordination with Austin Wildlife Rescue, the owlet was retrieved and is being rehabilitated.
What we don’t know:
Officials say early signs are encouraging and that the owlet is showing strength and appetite.
The exact cause of the death of the first owlet is now known, but the wildflower center says a variety of natural factors can affect survival, including food availability.
The backstory:
Since 2012, a pair of great horned owls have made a specific corner of the Lady Bird Johnson Wildflower Center their home. Like clockwork, the pair return each year to nest above the archway of the courtyard entrance, greeting visitors who pass beneath them.
The female owl, affectionately named Athena, has become a staple of the center.
Athena’s reach extends far beyond the local Austin community. Through a partnership with the Cornell Lab of Ornithology, the center hosts a 24/7 livestream of the nest, allowing bird-watchers from around the globe to monitor her progress in real-time.
The City of Austin also recently designated Athena the official Owl Ambassador of Austin.

America 250 celebration: Texans who fought for independence honored in Austin – Texas – The Black Chronicle
(The Center Square) – As part of Texas’ celebration of the founding of the United States, a new monument was unveiled in Austin commemorating 69 patriots who fought for U.S. independence who later came to Texas.
Texas is also celebrating its first U.S. Navy fleet week in state history in the Houston area, where roughly 1,000 sailors and Marines are participating in nearly 200 events as part of the America 250 celebration. This also includes commemorating the Texas Navy, which helped win Texas’ independence from Mexico 190 years ago this April, The Center Square reported.
Gov. Greg Abbott and the leaders of the Texas Society Sons of the American Revolution unveiled a new monument honoring Texas revolutionary war patriots at the Texas State Cemetery in Austin.
Abbott, a direct descendent of a patriot who supported the cause of American independence, was also inducted into the Sons of the American Revolution and received the Silver Good Citizenship Medal.
“It is appropriate to remember that today, April 18th, 251 years ago, the Battles of Lexington and Concord occurred with the shot heard around the world,” Mel Oller, president of the Texas Society of the Sons of the American Revolution, said.

On the evening of April 18, Paul Revere rode from Boston to Charlestown warning colonists that British troops were coming. Several hundred Minute Men and colonial militia fought British soldiers the next morning in Concord and Lexington, the first battles of the American Revolutionary War.
The commemoration in Austin was important “to reflect on the courage, sacrifice and enduring principles that gave birth to the United States of America,” Oller said. “This monument stands as a tribute to those patriots and reminder to future generations of the ideas that continue to shape our Republic.”
“Texans played a role in the war too, and it’s important to recognize them, and the sacrifices they made for our freedom,” he said.
“The history that is etched the United States into the annals of the greatest country in the history of the world,” Abbott said. As others try to rewrite American history or “try to condemn the glory of what America has been able to achieve,” Abbott said Texas was focusing on teaching children about U.S. and Texas history. “We must educate every generation about why it is that America grew from just a tenuous 13 colonies into the most powerful country in the history of the world.”
“There could hardly be a better time to dedicate this monument than during our 250th celebration of freedom, of independence,” he said. It’s “an enduring testament to the heroes who fought for that freedom that is unique to America.”
One of the greatest gifts Revolutionary War heroes gave Americans was freedom, Abbott said, “but freedom is not a one-time event. The fight didn’t end with the Treaty of Paris. It’s an everyday process, perpetually. Just as the patriots took to the hillsides to battle the Red Coats, modern day Patriots” continue to fight for freedom, including the failed policies of Marxism, he said. Many Texans’ ancestors “died for a country they would never get to see. Stories of these heroes must be told. Generations of Americans must be reminded of who they are and what they fought for.”

There are 69 American Revolutionary War heroes listed alphabetically on the monument who later settled in Texas, including native Tejanos who fought for American independence, according to TSSAR.
Listed first is John Abston, who enlisted in the militia in Virginia when he was 18. He fought alongside and under men like John Crockett, father of Davy Crockett, in one of the most pivotal battles of the war: the Battle of Kings Mountain, in South Carolina. He later moved to Collin County, Texas.
Another is José Santiago Seguín, the grandfather of Texas Revolutionary hero Juan Seguín, the first and only Tejano to be elected to the Republic of Texas Senate. He also fought with Sam Houston in the Battle of San Jacinto.
Another is Peter Sides, who fought with a North Carolina regiment against the British. He later joined the Gutierrez-Magee expedition in 1812 and was killed in 1813 at the Battle of Medina in what is now Bexar County. The battle is “known as the bloodiest battle on Texas soil. The rebels’ bodies were desecrated and their body parts were removed and scattered,” the TSSAR explains.
Another is William Sparks, who joined a North Carolina militia when he was 17. He and his family later moved to Nacagdoches, Texas; his sons and grandsons fought for Texas independence.
Listed at the bottom of the monument is Ira Hobart Evans, a Congressional Medal of Honor recipient and the youngest Speaker of the Texas House who founded the Texas Society of the Sons of American Revolution.
