If you’re someone who keeps jars and canisters because “you never know, they could come in handy,” this project is for you. Etching glass can unify all of those spare mismatched glass containers with ...

Plasma etching is perhaps the most essential process in semiconductor manufacturing, and possibly the most complex of all fab operations next to photolithography. Nearly half of all fab steps rely on ...

Copper’s resistivity depends on its crystal structure, void volume, grain boundaries and material interface mismatch, which becomes more significant at smaller scales. The formation of copper (Cu) ...

Once a printed circuit board (PCB) has been assembled it’s rather hard to look inside of it, which can be problematic when you have e.g. a multilayer PCB of an (old) system that you really would like ...

An example of directional etching for nanohole arrays of less than 500nm in diameter. (Image: A*STAR Institute of Materials Research and Engineering) Wet etching can be classified into two main types ...

Mass spectrometry, by contrast, is a powerful technique for the analysis of any process gas. Careful consideration of differences in pressure, reaction time scales and process flow is essential for ...
