“There's this whole set of tooling and fabrication lines that don't really go above 400°C (752°F), and they're built for that. And tantalum on silicon, when you use the old method, was right on the border of that,”

Olszewski discussed the fabrication challenges and temperature limits associated with traditional tantalum deposition on silicon.

“There was little margin to do things reliably. Using krypton brought that threshold down to 200°C (392°F). So you now have this big window to be able to do reliable fabrication.”

Olszewski explained how using krypton gas significantly widened the temperature margin for reliable chip fabrication.
