Thermo Scientific System Helps Isolate Electrical Faults

News

Meridian S all-in-one system includes both photon emission and static laser stimulation applications

Thermo Fisher Scientific, based in Hillsboro, Oregon, has introduced the Meridian S inverted Static Optical Fault Isolation (OFI) system, to allow semiconductor failure analysis labs to future-proof their operations.

Semiconductor failure analysis engineers and technicians can isolate electrical faults that cause semiconductor devices to fail at end-of-line test. These defects, such as metal shorts, opens, and transistor-level leakage, are localised in the failure analysis workflow to troubleshoot process or design failures and increase overall device manufacturing yield.

This all-in-one system includes both photon emission and static laser stimulation applications, and is a cost-effective, high-sensitivity solution for localising electrical failures in semiconductor devices.

The addition of Meridian S also provides semiconductor manufacturers with a reliable static OFI tool that delivers performance. Multiple upgrade paths are available, bringing the industry-leading capabilities of dynamic OFI and high sensitivity emission as customers' lab needs develop.

“Meridian S offers high optical resolution and enhanced sensitivity with a robust upgrade path for future expansion, all in a single tool,” said Debbora Ahlgren, senior director, materials and structural analysis, Thermo Fisher Scientific. “The result is a high return on investment and a concrete roadmap as customers increase their OFI capabilities.”

Meridian S offers several benefits designed to maximise performance:

- High-sensitivity probing: Meridian S includes FDx with Active Probe, a next-generation Static Laser Simulation (SLS) amplifier for applications such as Optical Beam Induced Resistance Change (OBIRCH) failure analysis.

- Static OFI analysis on a broader range of devices and package types: Meridian S offers both topside probing for flip chip packages and wafer pieces as well as - backside probing for conventionally packaged devices.

- Easy-to-use software: Meridian S is optimized to work with the proven Sierra software platform for enhanced ease of use and offers a number of features, including Live Emission mode which allows users to view photon emission signatures emerge in real-time.

- Laser marker option for physical markings of fault locations: Meridian S provides a laser marker option with an accuracy level better than 2 microns.

Meridian S will ship in the fourth quarter of 2019.



AngelTech Live III: Watch the virtual event ON-DEMAND!

AngelTech Live III was broadcast live on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and features online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

The event covered the whole spectrum of key developments affecting the compound semiconductor industry. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. This was considered a roadmap for this device, along with technologies for boosting its output.

With 3 interactive sessions over 1 day AngelTech Live III proved to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
