Hiding Behind the Mask

This lab, presented by the National Nanotechnology Infrastructure Network, covers the concept of semiconductor manufacturing. Students will learn about selective layering which is used to "build up some layers of patterned material so that very interesting things start to happen, like using voltage in one conducting part to control electron flow in a neighboring partâthe basis of transistor switches." A Teacher Preparation Guide, Student Guides, and Next Generation Science Standards applicable to the lesson are included
