Bringing Commercial Semiconductor Technology to the Defense Industry

Commercial innovation in 5G communications and other applications is driving rapid change in silicon technology. Defense forces seek to leverage this innovation and challenge the microelectronics industry to provide agile, leading-edge solutions that are also secure, trusted, and cost effective. Mercury is uniquely positioned at the intersection of high-tech and defense, and we are stepping up to that challenge.

Redefining Sensor Edge Processing with 2.5D System-in-Package Technology

Tom Smelker, VP and General Manager of Custom Microelectronics Solutions at Mercury Systems, shares how 2.5D microelectronics integration in semiconductor design is a powerful new trend that will deliver industry-leading performance in the smallest form factor possible.

Application Spotlight: Multifunction AESA

As threats evolve and become more advanced, there is a growing need for radar systems with the ability to adapt and respond. By bringing the latest in processing technology directly to the sensor aperture, an active electronically scanned array (AESA) can quickly transition between EW functions such as tracking and mitigating electronic threats, as well as weapons targeting and communications. With system-in-package technology, low-latency modules are installed on each antenna element to maximize the flexibility of the radar system.

System-in-Package and Multi-Chip Module Technologies

Through-Silicon Vias

For the ultimate in SWaP optimization, highly complex semiconductor devices are integrated in a system-in-package (SiP) using a custom-designed interposer with through-silicon vias (TSV). This technology reduces the need for large signal-routing boards, significantly reducing the size of sensor processing solutions to enable edge computing.


Powerful edge-computing systems require dense, ruggedized memory. To enable these applications, memory dies are stacked vertically. This Mercury-developed process has been proven in harsh, high-G environments and significantly reduces the physical size of the system. 

Multi-Chip Module Technology

For more than 30 years, Mercury's multi-chip module design and fabrication have provided innovative SWaP solutions for mission-critical systems.  Our advanced thermal and electrical modeling capabilities enable modern FPGA and processor adoption for the most advanced military and aerospace applications.  Tailored test solutions ensure only the highest quality products are delivered, resulting in a significant reduction of field failures.

Advanced Design, Manufacturing, and Test

Mercury is a dedicated, focused defense electronics manufacturer of rugged, miniaturized processing solutions that are designed, made and tested in private and trusted domestic Advanced Microelectronics Centers (AMCs). Our Phoenix AMC produces dense memorymilitary-grade SSD solutions, and custom system in package devices and has been recognized by many government, quality, and commercial enterprises for its excellence and capabilities.
