Abstract

Electronic devices—machines that contains billions of tiny switches called transistors—have revolutionized the way we live: from online shopping to remote working to instant access to the Internet. As these transistors are miniaturized down to the fundamental limit set by the laws of physics, localized heating in these minuscule switches can lead to an overheating or, in extreme case, a catastrophic failure. As such, there is an urgent need for metrology that can accurately identify these thermal anomalies, known as hot spots, in prototypical electronic gadgets. Our research focuses on the development of high-resolution, non-contact thermal sensing techniques that can identify these thermal hot spots. In particular, we use optically active defect centers, aslo known as quantum emitters, in wide bandgap semiconductors such as diamond to achieve such a goal. By leveraging the temperature-dependent emission of these defect centers, we can perform real-time temperature monitoring down to the sub-micron limit—revealing the uneven thermal distribution on these microelectronic devices.
