In the world of semiconductors, how do we draw the microscopic markings needed for their circuits to work? Mrs. Pope and the Chip Kids perform an experiment with antacids, vinegar, and tape to learn about the process of chemical etching. Learning about etching on antacids helps students to understand the process of etching in the creation of microchips. When microchips are etched, parts of the silicon wafer are removed to form a pattern of tiny circuits to allow the chips to process information and perform tasks.
Vocabulary for Students to Define: Microchip, Microfabrication, Semiconductor, Silicon Wafer, Etching, Masking
