Mahomet-Seymour High School,
Mahomet, Illinois

Year in Program:

2014-2015

Designed For:

High School Students

Overview

Students will use the photo-assisted etching of p-type silicon with potassium hydroxide solution to study principles of electronics manufacturing and chemical kinetics.

After completing this module, student should be able to:

  • describe the role of wet-chemical etching in semiconductor manufacturing.
  • describe the promotion of electrons in the band-gap region of p-type and n-type silicon.
  • analyze the effects of environmental variables on the rate of a chemical reaction.
