The announcement follows Diamond Quanta’s CES 2026 debut, where the company demonstrated 300 mm diamond-on-silicon wafer technology, designed for wafer-to-wafer (W2W) and chip-to-wafer (C2W) bonding compatibility, along with its first commercial diamond glass product, Adamantine Optics™. At CES, the company engaged with system OEMs, semiconductor manufacturers, and ecosystem partners around practical insertion points for diamond within advanced packaging flows.
Extending Diamond Quanta’s CES 2026 Demonstrations
Adamantine Thermal builds directly on the same engineered-diamond manufacturing approach introduced at CES. While diamond is well known for its high intrinsic thermal conductivity, its integration into modern semiconductor packaging has historically been limited by surface roughness, bonding compatibility, and manufacturability at scale.
Diamond Quanta’s approach addresses these challenges by combining:
- CMOS-compatible, low-temperature diamond growth on industry-standard substrates
- Laser-based densification to produce smooth, bond-ready diamond surfaces
- W2W and C2W bonding workflows that support integration into advanced packaging stacks
“Thermal is the most immediate and universal entry point for diamond in electronics,” said Adam Khan, Founder and CEO of Diamond Quanta. “Once diamond can be bonded reliably and at scale, it stops being a research material and becomes a practical platform.”
A key application area for Adamantine Thermal is engineered-diamond glass interposers, where diamond is integrated with glass cores that are already entering advanced packaging workflows. Glass interposers are gaining traction for signal integrity and dimensional stability, and the addition of diamond enables more uniform thermal management while improving flatness and mechanical robustness.
Adamantine Thermal is architected from the outset to support W2W and C2W bonding approaches that are critical for next-generation interposers and stacked systems. By maintaining compatibility with standard fab infrastructure and panel-scale workflows, the platform is designed to bridge today’s passive thermal materials and future diamond-enabled electronic architectures.
Diamond Quanta confirmed that Adamantine Thermal is entering partner evaluation programs, with engineered-diamond interposer concepts advancing in alignment with industry adoption cycles for advanced packaging. The thermal platform complements the company’s recently launched Adamantine Optics offering and reinforces a broader roadmap spanning thermal management, photonics, interposers, and future diamond-enabled systems.

U.S. President Donald Trump linked his aggressive stance on Greenland to last year’s decision not to award him the Nobel Peace Prize, telling Norway’s prime minister that he no longer felt “an obligation to think purely of Peace,” in a text message released on Monday.
Trump's message to Jonas Gahr Støre appears to ratchet up a standoff between Washington and its closest allies over his threats to take over Greenland, a self-governing territory of NATO member Denmark. On Saturday, Trump announced a 10% import tax starting in February on goods from eight nations that have rallied around Denmark and Greenland, including Norway.
Those countries issued a forceful rebuke. But British Prime Minister Keir Starmer sought to de-escalate tensions on Monday. While the White House has not ruled taking control of the strategic Arctic island by force, Starmer said he did not believe military action would occur.
"I think this can be resolved and should be resolved through calm discussion,” he said.
Still, the American leader's message to Gahr Støre could further fracture a U.S.-European relationship already strained by differences over how to end the nearly four-year war in Ukraine, previous rounds of tariffs, military spending and migration policy.
In a sign of how tensions have increased in recent days, thousands of Greenlanders marched over the weekend in protest of any effort to take over their island. Greenland Prime Minister Jens-Frederik Nielsen said in a Facebook post Monday that the tariff threats would not change the their stance.
“We will not be pressured,” he wrote.
Meanwhile, Naaja Nathanielsen, Greenland’s minister for business, minerals, energy, justice and equality, told The Associated Press that she was moved by the quick response of allies to the tariff threat and said it showed that countries realize “this is about more than Greenland.”
“I think a lot of countries are afraid that if they let Greenland go, what would be next?”
Trump's message to Gahr Støre, released by the Norwegian government, read in part: “Considering your Country decided not to give me the Nobel Peace Prize for having stopped 8 Wars PLUS, I no longer feel an obligation to think purely of Peace, although it will always be predominant, but can now think about what is good and proper for the United States of America.”
It concluded: “The World is not secure unless we have Complete and Total Control of Greenland.”
The Norwegian leader said Trump’s message was a reply to an earlier missive sent on behalf of himself and Finnish President Alexander Stubb, in which they conveyed their opposition to the tariff announcement, pointed to a need to de-escalate, and proposed a telephone conversation among the three leaders.
“Norway’s position on Greenland is clear. Greenland is a part of the Kingdom of Denmark, and Norway fully supports the Kingdom of Denmark on this matter,” the Norwegian leader said in a statement. “As regards the Nobel Peace Prize, I have clearly explained, including to president Trump what is well known, the prize is awarded by an independent Nobel Committee and not the Norwegian Government.”
He told TV2 Norway that he hadn't responded to the message, but "I still believe it’s wise to talk," and he hopes to talk with Trump in Davos this week.
The Norwegian Nobel Committee is an independent body whose five members are appointed by the Norwegian Parliament.
U.S. Treasury Secretary Scott Bessent defended the president’s approach in Greenland during a brief Q&A with reporters in Davos, Switzerland, which is hosting the World Economic Forum meeting this week.
“I think it’s a complete canard that the president would be doing this because of the Nobel,” Bessent said, immediately after saying he did not “know anything about the president’s letter to Norway.”
Bessent insisted Trump “is looking at Greenland as a strategic asset for the United States,” adding that “we are not going to outsource our hemispheric security to anyone else.”
Trump has openly coveted the peace prize, which the committee awarded to Venezuelan opposition leader María Corina Machado last year. Last week, Machado presented her Nobel medal to Trump, who said he planned to keep it though the committee said the prize can’t be revoked, transferred or shared with others.
In his latest threat of tariffs, Trump indicated they would be retaliation for last week’s deployment of symbolic numbers of troops from the European countries to Greenland — though he also suggested that he was using the tariffs as leverage to negotiate with Denmark.
European governments said that the troops traveled to the island to assess Arctic security, part of a response to Trump’s own concerns about interference from Russia and China.
Starmer on Monday called Trump’s threat of tariffs “completely wrong” and said that a trade war is in no one’s interest.
He added that “being pragmatic does not mean being passive and partnership does not mean abandoning principles.”
Six of the eight countries targeted are part of the 27-member European Union, which operates as a single economic zone in terms of trade. European Council President Antonio Costa said Sunday that the bloc’s leaders expressed “readiness to defend ourselves against any form of coercion.” He announced a summit for Thursday evening.
Starmer indicated that Britain, which is not part of the EU, is not planning to consider retaliatory tariffs.
“My focus is on making sure we don’t get to that stage,” he said.
Denmark’s defense minister and Greenland’s foreign minister are expected to meet NATO Secretary-General Mark Rutte in Brussels on Monday, a meeting that was planned before the latest escalation.
