Understanding the Adoption of Si, SiC, and GaN Wafers

The panel discusses how silicon (Si), silicon carbide (SiC), and gallium nitride (GaN) materials influence semiconductor design choices, yield challenges, and supply chain risks.

Material selection impacts performance, cost, and supply stability. This episode details why silicon remains dominant, the niche advantages of SiC and GaN, and the specialized defect and purity controls needed to support next-generation applications.

Key discussion topics include:

  • The benefits and trade-offs of wide bandgap materials.
  • Impact of substrate defects on advanced device reliability.
  • The importance of acoustic spectroscopy and recycling for GaN.

In this segment of our SciX interview with Kevin Wilkinson, a professor of environmental chemistry at the Université de Montréal, discusses extending lead isotope work to greater distances and explains why graduate students need adaptability, critical judgment, and coding skills more than expertise in any single instrument.
Atoms Don't Lie–The Remaking of Atomic Spectroscopy, © Hallie -chronicles-stock.adobe.com
Atomic spectroscopy has quietly gone from counting elements in bulk to counting single nanoparticles, imaging tissue at the micrometer scale, and reading Martian rocks from several meters away. The instruments got smaller, the software got smarter, and the questions they can now answer got a lot more interesting.
