Wet Etching in Nanofabrication

Curated and Reviewed by Lesson Planet

Chemistry and physics combine forces to benefit nanofabrications. Learners examine the process of wet etching in nanofabrication. Using corrosive substances such as lemon juice and Coca-Cola, they model the etching process. They then make the connection to how the same process helps to design components in electronics.
