This lab, presented by the National Nanotechnology Infrastructure Network, students will "help students understand how chemical reactions are used to create the specific shapes on surfaces of crystalline materials, which make up functional components within electronics." The wet etching process is used to create computer chips, and through this simulated lab, students will have a chance to explore the same process using different materials. Included in this lab are: Student Worksheet #1, Student Worksheet #2, Student worksheet 1 with answers, Student worksheet 2 with answers, and Teacher guide.
