Semiconductor industry electrical test and measurement supplier FormFactor has deployed an integrated CM300xi probing solution for wafer-level testing of silicon photonics (SiPh) devices. The T&M specialist says it worked with teams from semiconductor house GLOBALFOUNDRIES (GF) and photonics test and measurement company Keysight Technologies to make the system flexible to accommodate various engineering needs and to deliver high throughput in volume production.

The Cascade CM300xi from FormFactor, combined with Keysight Technologies’ Photonics Application Suite measurement software, is designed to provide industry-first capabilities of automated alignment and simultaneous optical-optical and optical-electrical device tests. Key features of the system include:
-Six-axis automated optical fibre positioning for precision alignment
-Two-stage solution for both coarse and fine alignment
-Optical alignment algorithms integrated with high-speed hardware control to shorten test times
-FormFactor’s SiPh software to simplify integration with Keysight’s Photonics Applications Suite and optical instrumentation
-Customised scripting and test programs to optimise the system for fast, accurate measurements
-Keysight’s high speed, single sweep Polarisation-Dependent-Loss (PDL) test that enables high accuracy and repeatability testing without prior polarisation alignment.

“Emerging technologies like silicon photonics offer FormFactor the opportunity to develop fully integrated probe systems. GF is a forward-thinking company in their adoption of these new test technologies,” said Mike Slessor, President and CEO of FormFactor. “Our collaboration with both Keysight and GF Singapore delivers a solution that truly addresses the unique test and measurement challenges of silicon photonics devices.”

“With our long history of working with FormFactor to deliver wafer measurement solutions and decades of experience in photonic testing we are pleased to further equip the silicon photonics industry,” added Joachim Peerlings, Vice President and General Manager Networks & Data Centers, Keysight Technologies. “With Keysight’s Photonics Application Suite and instrumentation, we’ve built a proven, integrated measurement system that enables customers to quickly develop test routines that provide deep insight into photonics devices during R&D and design validation and has the flexibility and scalability for cost effective high-volume production.”
