300 mm Probe Station with Integrated Silicon Photonics Wafer and Die-Level Probing Solution

The CM300xi-SiPh 300 mm probe station is the first verified integrated measurement solution on the market that enables engineering and production-proven, optimized optical measurements right after installation – without further development. This unique Autonomous SiPh Measurement Assistant provides a groundbreaking set of functions that precisely calibrate the optical positioning hardware to the probe station and verify the performance of the integrated system.

In combination with the revolutionary OptoVue for advanced calibrations, intelligent machine vision algorithms and the exclusive SiPh TopHat for dark, shielded and frost-free environment, the system enables true hands-free autonomous calibration and re-calibration at multiple temperatures. This enables faster time to more accurate measurements and reduced cost of test.

FormFactor’s exclusively developed SiPh-Tools and Photonics Controller Interface (PCI) provide powerful software tools for alignments, data collection and analysis. This includes all necessary algorithms for using fibers and fiber arrays with both surface and edge coupling applications.

FormFactor provides all the tools, fixtures and functionality needed to enable you to be performing silicon photonic probing on your photonic devices in days instead of months or years.

Solving the Data Center Energy Crisis with Silicon Photonics | Dr. Choon Beng Sia

A deluge of business data flows into corporate data centers each day, faster than anyone can sort through it. At the same time, consumers are communicating, browsing, buying, sharing, and searching—creating their own enormous trails of data and an incredible energy demand at data centers. FormFactor’s Dr Choon Beng Sia presents a paper on the application of Silicon Photonics (SiPh) devices, how these new devices can help lower energy consumption in data centers, why accurate and reliable wafer-level photonics test are needed, and how FormFactor is helping to address the challenges of testing SiPh devices.
