Aeluma signs G10‑AsP equipment purchase agreement with AIXTRON

An equipment order for larger-wafer photonics production leaves the expansion's cost and start date undisclosed. Aeluma, Inc. NASDAQALMU, a Goleta, California, photonic and electronic semiconductor developer, announced on Thursday an agreement to purchase a system configured for 150 mm and 200 mm wafers.

AIXTRON SE ETRAIXA, the semiconductor deposition-equipment supplier, will provide its G10-AsP metalorganic chemical vapour deposition system. Aeluma says the tool will support development and expand manufacturing capacity for its photonics platform that does not rely on indium-phosphide substrates.

The Nov. 12 announcement discloses no purchase price, deposit or payment schedule, and gives no delivery or installation date. It also provides no wafers-per-month target or measured device yield. Financial results due after Thursday's U.S. market close offer the next scheduled business update.

Aeluma shares closed at US$7.21 on Nasdaq at 4:00 p.m. EST on Nov. 11, according to the NASDAQALMU snapshot. That close preceded the equipment announcement.

AIXTRON traded at €34.21 on Xetra at 1:11 p.m. CET on Nov. 12, according to the ETRAIXA snapshot.

The Tool Supports Larger Wafer Formats

AIXTRON's G10-AsP specifications, available on Nov. 12, describe automated cassette-to-cassette wafer handling and automated chamber etch-back. The supplier lists compatibility with wafer diameters extending from 75 mm to 200 mm.

Aeluma's announcement identifies the larger formats supported by its configured system. It says the equipment has been adapted for its proprietary processes, rather than presenting the catalogue specifications as demonstrated production results at Aeluma.

The intended manufacturing route integrates compound semiconductor materials with microelectronics-grade gallium arsenide or silicon substrates. The purchase supports Aeluma's non-indium-phosphide platform, so the system's broader capability to process other materials does not describe the company's chosen substrate strategy.

"The AIXTRON G10-AsP platform is aligned with our strategy to scale photonic device manufacturing on 150 mm and larger substrates," Aeluma founder and chief executive Jonathan Klamkin said in the Nov. 12 release.

Klamkin identified high-speed photodetectors and quantum dot lasers among the devices being developed for AI computing architectures. The announcement names no customer placing a production order for those devices and gives no shipment schedule.

June Cash Followed Share Sales

Aeluma entered this investment programme with US$56.0 million in cash and cash equivalents at June 30, according to its Sept. 16 fiscal-year results. The company reported US$20.1 million in net proceeds from at-the-market share sales during that quarter.

Those results already described procurement of additional deposition tools to increase wafer production capacity. The Nov. 12 agreement identifies a supplier and equipment model within that expansion effort, without quantifying how much production the purchase adds to the earlier plan.

For the fiscal year ended June 30, revenue was US$4.5 million, compared with US$4.7 million a year earlier. It came primarily from government research and development contracts, while the company described negotiations with prospective AI data-communications customers.

For fiscal 2026, the annual net loss widened to US$9.2 million from US$3.0 million. Aeluma attributed the increased loss primarily to investment in new hires and manufacturing readiness, putting the equipment expansion alongside an already rising development budget.

The Sept. 16 release also disclosed a letter of intent for up to US$30 million from the U.S. Department of Commerce CHIPS research office. Aeluma said that funding remained subject to definitive agreement negotiations; the proposed award was separate from its reported June cash balance.

In its Sept. 16 results, Aeluma said its workforce had grown from 14 to more than 30 people. Management identified technology and product development, together with expanded customer engagement, as priorities for fiscal 2027.

Results Are Due After Thursday's Close

Rigetti Computing, Inc. NASDAQRGTI, the Berkeley superconducting quantum-computer developer, reported on Nov. 10 that it was investing in refrigeration capacity while targeting a larger system for mid-2028. Its equipment spending serves a different technology, but also precedes a dated hardware objective.

Mugglehead's Nov. 11 briefing on Rigetti's development budget followed that investment timetable alongside quarterly revenue of US$1.4 million. Aeluma's equipment announcement gives no comparable dated production objective.

Aeluma's next scheduled disclosure is its fiscal first-quarter report after the U.S. market close on Nov. 12. The company has scheduled its results and business-outlook call for 5:00 p.m. EST that day. That is the next scheduled opportunity to address the equipment commitment and production timetable.
