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 ...

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 process he describes starts after the board has already been etched. First he rolls on the soldermask, and then sandwiches the board between layers of transparency film and clear acrylic ...

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 ...
