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 ...

Yes, that's the famous mantra from the 1984 cult classic "The Karate Kid," but the phrase also describes what employees do at Industrial Engraving and GB Embossing in northeastern Wisconsin. But they ...

Photolithography dominates modern fabrication—but it’s slow, complex, and equipment-heavy. This video shows how laser-etched ...

The approach addresses a fabrication problem that becomes particularly important with superconductors. Conventional wet and dry etching can introduce rough ...

UCLA doctoral student Yilin Wong noticed that some tiny dots had appeared on one of her samples, which had been accidentally left out overnight. The layered sample consisted of a germanium wafer ...

The groundbreaking discovery could open new doors for other researchers working with delicate materials such as cell membranes. (Nanowerk News) Imagine drawing on something as delicate as a living ...

What Is Etching In Semiconductor Manufacturing? In semiconductor manufacturing, etching is a crucial process that sculpts the intricate circuits on a silicon wafer. It works by selectively removing ...

Some enzymes can chew through synthetic polymers. Researchers would like to harness this ability to etch channels, trenches, and holes into biocompatible materials as a way to fabricate drug delivery ...
