UCLA doctoral student Yilin Wong noticed that some tiny dots had appeared on one of her samples, which had been accidentally ...

Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led to the discovery of beautiful spiral patterns etched on the surface of the semiconductor by a ...

You may have seen this demonstrated in high school chemistry; a preparation of Tollen’s reagent, a mix of sodium hydroxide, ammonia, and silver nitrate, is mixed with glucose in a glass vessel.

Let’s take a look at a few of the more popular etching methods to understand the chemistry behind your boards. At the end of the day, PCB etching is all about removing copper from a board in as ...

What is Reactive Ion Etching (RIE)? Reactive Ion Etching (RIE) is a dry etching technique widely used in the fabrication of micro- and nanodevices. It combines the chemical reactivity of reactive ...

Atomic layer etching (ALE) is the reverse of atomic layer deposition (ALD). ALE can be achieved using sequential, self-limiting thermal reactions. We have recently demonstrated Al 2 O 3 ALE [1-3] and ...

The PECVD process modules are mainly developed to produce outstanding uniformity and high-rate films, with control of film properties, such as electrical characteristics, refractive index, stress, and ...

Advanced Chemical Etching (ACE), which is approaching its 25th anniversary in business later this year, has installed two additional single chamber Chemcut etching machines and a state-of-the-art ...

Telford precision manufacturer Advanced Chemical Etching has completed a £350,000 investment drive, as the company looks to grow its market in sectors such as aerospace and medical. ACE, which is ...
