Abstract: This paper explores the feasibility and the impact of frequency tuning suspended acoustic resonators through ion beam assisted argon gas cluster etching. To do so, groups of suspended ...

We report the fabrication of nanoporous silicon (nPSi) electrodes via electrochemical etching to form a porous Si layer with controllable thickness and pore size. Varying the etching time and ...

When there are small children in the house, crayon and colour pencil marks on the walls are quite common. These playful acts are part of their growth and development. If you don’t want to restrict ...

Back in 2006, University of California, Los Angeles (UCLA) engineer Patrick Pribyl had an idea for a better way to control the plasma used in chip manufacturing during the etching process.

A TikToker compared the quality of white Crayola crayons from 2017 and today, and the clear drop has artists seeing red. In a 13-second video, the user shows how the new crayon leaves a much ...

The bottom surface is slip-resistant rubber with etchings that boost traction on slippery and uneven surfaces. There’s even a heel loop to easily slip into them and go. This Lightweight Matching ...

Abstract: Junctionless FinFETs with an array of ultra-high aspect ratio (HAR) fins, enabled by inverse metal-assisted chemical etching, are developed to achieve high on-current per fin. The novel ...

[Lorentio Brodeso]’s ‘LACED’ project offers one such method, using both chemical etching and a 5 Watt diode engraving laser to remove the soldermask, copper and FR4 fiberglass layers.
