Shares of Aehr Test Systems (NASDAQ:AEHR) rose 5.8% in premarket trading Tuesday after the company announced a follow-on production order from its lead silicon photonics wafer-level burn-in customer.
The purchase is for a fully automated FOX-XP multi-wafer production burn-in system intended to support the customer’s manufacturing capacity expansion for next-generation silicon photonic integrated circuits. Aehr said the system is expected to ship during the first half of calendar 2027.
Configured with nine independent WaferPak test blades, the ordered FOX-XP system provides production burn-in and reliability screening capability for silicon photonic integrated circuits used in optical transceivers and chip-to-chip optical I/O applications. Each WaferPak blade is capable of delivering up to 3,500 watts of power.
The delivery will include Aehr’s fully integrated automated wafer-level handling solution. That package comprises the FOX-XP multi-wafer production burn-in system, an integrated WaferPak Auto Aligner, robotic wafer handling, and automated wafer loading and unloading, enabling wafer-level throughput and handling in a production environment.
Gayn Erickson, President and Chief Executive Officer of Aehr Test Systems, said: "This production order is another indication that silicon photonics is moving from technology adoption into manufacturing scale-up, and we believe that transition represents a significant long-term growth opportunity for Aehr."
Erickson added: "Over the past year, we’ve seen a meaningful increase in engagement from silicon photonics companies around the world spanning engineering qualification systems, production capacity planning, and next-generation device roadmaps."
Aehr supplies test and burn-in solutions for semiconductor devices across multiple end markets, including artificial intelligence, silicon photonics, data center, automotive, and industrial applications.
Key points
- Aehr received a follow-on production order for a FOX-XP multi-wafer burn-in system from its lead silicon photonics wafer-level burn-in customer.
- The system is built with nine WaferPak test blades, each able to deliver up to 3,500 watts, and is meant for production burn-in and reliability screening of silicon photonic integrated circuits used in optical transceivers and chip-to-chip optical I/O.
- Sectors influenced include semiconductor manufacturing, photonics, data center equipment, and AI hardware, reflecting Aehr’s reach across multiple device end markets.
Risks and uncertainties
- Timing uncertainty - the ordered system is expected to ship in the first half of calendar 2027, which creates a defined but future delivery window.
- Customer concentration - the order is described as coming from Aehr’s lead silicon photonics wafer-level burn-in customer, indicating exposure to individual customer demand for production volume.
- Technology-to-scale transition - while management describes silicon photonics as moving into manufacturing scale-up, that transition is characterized as ongoing, implying uncertainty around the pace and breadth of adoption.
