Commercial 14nm Processors Exhibit Vulnerability to Ionizing Radiation

State-of-the-art commercial 14nm CMOS processors, even those designed for consumer applications, can be susceptible to performance degradation and failure when exposed to ionizing radiation.

Academic Publication · 2015

Key Findings

01The 14nm 'Broadwell' U-series processor showed susceptibility to total ionizing dose (TID).
02Exploratory trials at a medical proton facility provided initial insights into its behavior under proton irradiation.

Application

Design takeaway

When designing systems for environments with potential radiation exposure, do not assume commercial processors are inherently radiation-hardened; verification testing is necessary.

How to apply

For projects involving aerospace, medical devices, or industrial controls, incorporate radiation testing or select components with known radiation-hardened specifications.

Project actions

01When selecting components for a design project, research their environmental tolerances.
02Consider the operating environment of your design and its potential impact on component reliability.

Method & Evidence

AimTo assess the radiation hardness of a commercial 14nm CMOS processor (Intel 'Broadwell' U-series SoC) under total ionizing dose (TID) and exploratory proton irradiation.

MethodExperimental testing

ProcedureThe study involved exposing a commercial 14nm CMOS processor integrated onto a laptop motherboard to ionizing radiation. Instead of traditional automated test equipment, the researchers utilized commercial laptop motherboards and software stress applications to simulate real-world operating conditions and evaluate the processor's performance and reliability under radiation.

ContextElectronic component reliability testing for radiation environments.

Variables

IVIonizing radiation (Total Ionizing Dose, Proton Irradiation)

DVProcessor performance, functionality, error rates

CVProcessor model (14nm 'Broadwell' U-series), test environment (laptop motherboard, software stress applications)

Strengths & Limitations

Strengths

+Utilized a state-of-the-art commercial processor.
+Employed realistic testing methods using commercial motherboards and software.

Limitations

The cost and complexity of performing actual radiation testing can be a significant barrier for student design projects.

Reliability & validity

The use of commercial hardware and software for testing increases ecological validity, but may introduce variability not present in highly controlled ATE environments. The exploratory nature of the proton trials suggests further validation may be needed.

Think critically

To what extent should designers rely on manufacturer specifications for radiation tolerance versus conducting independent testing for critical applications?

Design Principles

"Component selection for critical applications requires thorough validation of environmental resilience, including radiation tolerance."

This finding is critical for designers and engineers developing electronic systems for environments where radiation exposure is a concern, such as aerospace, medical equipment, or industrial control systems. It highlights the need to consider radiation effects early in the design process, even when using seemingly robust commercial-off-the-art components.

What This Means for Your Design

Even the newest computer chips can break when exposed to radiation, so if you're making something for space or a hospital, you need to check if the chips can handle it.
