Semiconductor electrical and physical failure analysis of advanced logic devices

Semiconductor failure analysis plays a crucial role in the development and reliability assessment of semiconductor devices, involving the identification and understanding of electrical, thermal, and mechanical issues.


Semiconductor electrical failure analysis

Thermo Fisher Scientific is the leading provider of electrical failure analysis (EFA) solutions that meet the evolving semiconductor requirements for finding buried defects with shrinking feature size, backside power delivery, and complex 3D integration. EFA techniques have the common end goal of providing the most precise defect characterization and location so that subsequent physical analysis can generate the best possible root cause answer.

Thermo Fisher Scientific’s failure analysis workflows for advanced logic devices

 

 

The Thermo Scientific ELITE System uses lock-in thermography (LIT) to provide high-speed, non-destructive defect isolation on the most advanced packaged die. It can identify and localize defects in a wide variety of complex packages in x, y, and z using its high-sensitivity thermal imaging camera. It can localize the defect to within a specific die or interconnect area and is generally followed by some form of decapsulation and analysis at the die level.

 

For bare or decapsulated die, there is still a need to isolate a particular failing gate within its billions of neighbors, and this task is accomplished by workflows consisting of FIB delayering and nanoprobing applications.

The nProber IV System provides electron beam probing for transistor-level fault localization

The Thermo Scientific Helios 5 PFIB DualBeam and Helios 5 Hydra DualBeam provide proprietary, damage-free, accurate delayering on even the most advanced logic technology nodes.

 

Following FIB delayering or FIB sample preparation, the probing techniques that are frequently used are a combination of the Thermo Scientific Meridian EX Fault Isolation System's electron beam probing, the Meridian IV System's optical fault isolation, and the Thermo Scientific nProber IV System's physical nanoprobing. These instruments perform accurate and rapid characterization of the defect that can then be passed on to a physical failure analysis (PFA) workflow for root cause analysis.

The Thermo Scientific ELITE System utilizes lock-in IR thermography (LIT) to accurately and efficiently locate variations in the local power dissipation that lead to local temperature increases and to provide non-destructive 3D device insights.

Meridian EX Fault Isolation System

The Thermo Scientific Meridian EX is a unique e-beam probing solution for advanced logic failure analysis. It solves the challenges associated with feature size and access through back side power distribution.

nProber IV System

The Thermo Scientific nProber IV System is a high-performance SEM-based platform for the localization of transistor and metallization faults. It is the most advanced nanoprobing system in the world and the first to use the high-resolution LEEN2 SEM Column specifically designed to increase speed, accuracy, and output at a critical path in FA workflow, where productivity is paramount.

Helios 5 Hydra DualBeam FIB-SEM

The Thermo Scientific Helios 5 Hydra DualBeam FIB-SEM has a selectable ion (Xe, Ar, O, and N) column that enables superior cross-section quality, throughput, and gallium-free TEM sample preparation for compound semiconductor and device packaging materials. Combine with powerful Thermo Scientific Avizo Software for high-resolution 3D data for process monitoring and defect detection.


Semiconductor physical failure analysis

Following electrical characterization and localization, precision root cause analysis is required. As every defect is extremely valuable, it is important that the highest quality analytical data is collected from every sample with the fastest possible time to data. This requires precise, highly repeatable TEM sample preparation using the Thermo Scientific Helios 6 HD FIB-SEM, followed by highly trusted, user-friendly TEM imaging and analysis with the Thermo Scientific Talos TEM and Spectra (S)TEM. The Helios FIB-SEM to Talos or Spectra TEM workflow is now established as the trusted solution for logic failure analysis.

Helios 6 HD FIB-SEM

The Thermo Scientific Helios 6 HD Focused Ion Beam Scanning Electron Microscope (FIB-SEM) is designed to meet the industry need for higher volumes of high-quality TEM data for failure analysis and metrology. Producing higher quality TEM data provides actionable information to maximize manufacturing yields and end-product quality.

Talos F200E TEM

The Thermo Scientific Talos F200E Scanning Transmission Electron Microscope combines outstanding high-resolution scanning transmission electron microscope and transmission electron microscope imaging with exceptional energy dispersive X-ray spectroscopy (EDS) signal detection and 3D characterization with compositional mapping.

Spectra Ultra (S)TEM

The Thermo Scientific Spectra Ultra Scanning Transmission Electron Microscope introduces cutting-edge capabilities designed to overcome structural and material challenges, setting a new standard in advanced TEM analysis. Flexible high-tension switching lets you quickly switch voltages for your specific needs. In addition, the high-performance Thermo Scientific Ultra-X Detector shortens elemental mapping time and makes it possible to analyze beam-sensitive structures.
