Keysight's NX5402A Silicon Photonics Wafer Test System delivers quick volume production launch with stability and repeatability.

Keysight Technologies Inc.’s NX5402A Silicon Photonics Wafer Test System integrated with the PathWave Semiconductor Test software technology (part of Keysight PathWave Test software), enables semiconductor manufacturers to speed delivery of silicon photonics wafer production with stable and repeatable test capabilities.

Silicon photonics is one of the key emerging technologies addressing growing internet traffic and demand for higher data rate. Silicon photonics’ primary applications are in the data center market, driven by big data and cloud applications, but it is expected to be used in other areas, including healthcare, automotive Light Detection and Ranging (LiDAR), optical computing and quantum computing.

According to a recent market research report by Yole Développement, the overall silicon photonics market will reach $3.9 billion in 2025. As a result, many manufacturers are considering silicon photonics fabrication. However, there has not been any commercially available silicon photonics testing equipment for mass production using fully automated wafer probers. In addition, silicon photonics testing requires a variety of sensitive and accurate measurements. Companies and system integrators are pursuing system optimization and maintenance due to complex and inefficient communications with multiple vendors.

“Ahead of the growing market demand for silicon photonics, Keysight is excited to announce the first test solution for silicon photonics volume production market,” said Shinji Terasawa, vice president and general manager of Keysight’s Wafer Test Solutions group. “Our NX5402A test system is the first solution that combines Keysight’s expertise in electrical and optical measurement with Keysight’s fiber alignment and positioning system integrated by PathWave Semiconductor Test software.”

Keysight’s new NX5402A Silicon Photonics test system provides proven measurement technologies and direct support capabilities including integrated optical and electrical test capabilities and Keysight-developed fiber alignment and positioning system based on Keysight’s measurement science. It eliminates manual operations with PathWave Semiconductor Test software, which is compatible with Keysight’s SPECS software, thus enabling one-pass silicon photonics testing.

The system is volume production ready. Its factory automation software, safety interlock, and clean room ready features support manufacturing use, providing high throughput testing based on multi-channel optical and electrical test architecture, as well as optimized fiber alignment. It also maintains high accuracy, repeatability and reproducibility from laboratory to fabrication, delivering advanced wafer-level photonic calibration, as well as reliable performance monitoring with built-in automatic system diagnostics.
