View Resource Silicon Wafer Polishing

This Quicktime animation demostrates the final polishing and cleaning processes required for creating semiconductor devices and integrated circuits. This animation is the sixth in a series of how silicon wafers are created. The previous animation showing silicon wafer lapping can be seen here. The next animation in this sequence about the optional silicon wafer epitaxy process can be seen...

View Resource Silicon Wafer Lapping

This Quicktime animation shows how the machining process of "lapping" removes controlled amounts of silicon from a wafer in order to ensure flatness of the silicon wafer. This process removes particles and improves the quality of the wafer after they are cut. This animation is the fifth in a series of how silicon wafers are created. The previous animation showing silicon ingot edge profiling...

View Resource Molecular Expressions: Electricity and Magnetism

This interactive Java tutorial explores the many steps necessary to build a transistor on a silicon wafer. It allows you to explore how an individual Field Effect (FET) transistor is fabricated on a silicon wafer simultaneously with millions of its neighbors. Keywords: Photoresist, doping, deposition, silicon

View Resource Silicon, Circuits and the Digital Revolution

This Honors colloquium introduces first-year students to some of the science behind high technology. Designed to promote scientific and computer literacy and awareness, it gives students an opportunity to leverage their interests in everyday devices and high-tech objects into a study of fundamental science concepts. Live demonstrations, in-class group explorations of technology applications, and...

View Resource Silicon Ingot Wire Cutting Animation

This Quicktime animation is of a single wire slicing the silicon ingot into thin wafers. By using a thinner wire, and by cutting all wafers at that same time, this minimizes material loss. This animation is the third in a series showing silicon wafer production process after it has been ground to the correct diameter. The previous animation showing silicon ingot rod grinding can be seen here...
