This lab, presented by the National Nanotechnology Infrastructure Network, introduces students to "some of the challenges of making semiconductor chips and waveguides." These parts of electronic circuits will help students to understand the role of nanotechnology and nanofabrication processes and specifically the application of photolithography in computer chip manufacturing. In this lab, students will be "creating images using masks and ultraviolet light. Ultraviolet light causes molecules in the coating of solar print paper to bind together and form a new compound." Stenciling is the same technique that photographers use and engineers to make computer chips, and students will be exploring this concept on a smaller scale. Included in this lab are: teacher preparation guide, student guide with answers, student guide with homework, and a student guide.
