Photolithography

This activity is designed for high school students. In this experiment students use UV light to transfer a pattern (either a network of very small metal wires or self-drawn patterns) onto a surface-- a plastic board. The pattern is transferred by placing a mask (transparency sheet with the pattern) on a plastic board. The board is coated with a copper film that is covered with a light-reactive polymer (photo-resist). The polymer is exposed to UV light through the mask to make a pattern in the polymer. The metal under the exposed polymer is then chemically etched, leaving only the...
