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 ...

This can become a problem; if the process is not tightly controlled, the etching reactions can extend ... Compounds with metal cations (positively charged species) have traditionally used ...

[Frankie] and [Bryan] have figured out a way to use the laser to chemically activate an etching process. See experiment part 2 as well. First, to be clear, they are using a quality 40W Epilog Zing ...

The process modules provide high precision, high throughput, and outstanding uniformity with clean smooth vertical profiles and etch surfaces. The systems have an extensive install base inside high ...

secondary ion mass spectrometer that is designed for analyzing secondary ions from the ion beam etch process. This system is equipped with integrated software consisting of process specific algorithms ...
