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 ...

Major processes in semiconductor wafer fabrication: 1) wafer preparation, 2) pattern transfer, 3) doping, 4) deposition, 5) etching, and 6) packaging. The process of creating semiconductors can be ...

Let's explore best practices for designing with PCE, highlighting how the process encourages new thinking in product ...

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 ...

While most of the time the name of the game is to remove a lot of metal, etching is an entirely other process. If you just want to put a logo on a piece of steel, or etch some labels in a piece of ...
