Over the course of 24–48 hours, a chemical reaction catalyzed by the metal film etched remarkable patterns on the germanium surface. Investigation of the process revealed that the chromium and ...

The reactors in the group currently include: 5 Hot wall viscous flow reactors equipped with an in situ quartz crystal microbalance (QCM) to monitor film growth and etching. One of these reactors can ...

You have extreme uniformity, and you don’t have to remove the entire film,” said Dan Hutcheson, vice chairman of TechInsights. “With selective etch, you are hammering away at the film until it’s all ...
