Serendipitous discovery reveals how stress and chemistry etch mysterious spiral patterns
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 ...
Etching is a method employed during the fabrication of semiconductors to chemically remove layers from the surface of the wafer substrate. Etching is a crucial process, and each wafer is subject to ...
A logarithmic spiral with a diameter of 500 μm, approximately half the diameter of a sewing needle. Curiosity about a mistake that left tiny dots on a germanium wafer with evaporated metal films led ...
