What exactly is going on in there to remove the copper? And how does the etching method affect the final product? Let’s take a look at a few of the more popular etching methods to understand the ...

To do so, he created an innovative printing process, which is recreated by [Michael Phillips] in the video after the break. Much like etching a PCB, Blake started with a copper sheet, writing and ...

With highly-selective etch, a specialized etch tool removes or etches away materials in tiny chip structures during the IC production process. In addition, these highly-selective etch tools have the ...

The team’s approach uses a cryogenic etching process using hydrogen fluoride plasma rather than the traditional method. "Cryo etch with the hydrogen fluoride plasma showed a significant increase ...

Atomic layer etching (ALE) is a highly controlled and selective etching technique that removes material layer by layer at the atomic scale. It is a cyclic process that relies on self-limiting chemical ...

Anisotropic wet etching is a common method for fabricating nanowires from various materials, such as silicon, germanium, or III-V semiconductors. By using etchants with high selectivity for specific ...

We are proud to have been chosen as the exclusive supplier for this critical hydrogen application,” said Markus Rettig, sales ...

Investigation of the process revealed that the chromium and ... and the composition of the etching solution all play a role in determining the type of pattern that develops," Zocchi said.

Similar to how a ship rusts when exposed to seawater, plasma used during the etching process continuously reacts with the internal components of the equipment, leading to corrosion and contamination.

In a separate development, A*STAR has devised a new plasma etching process for microelectromechanical systems (MEMS). A*STAR has developed a two-step plasma etching process, which produces vias with ...
