STEP - Transistors

Module Objectives

  1. Introduce students to science and engineering career opportunities.
  2. Develop deeper understandings of science concepts through analysis of applications.
  3. Develop vocabulary needed to converse in the semiconductor and nanotechnology industries.
  4. Develop skills needed to explore high-tech concepts independently.

Major Understandings

  1. A MOS transistor can be thought of as two back-to-back P-N junction diodes.
  2. A transistor can be thought of as a current switch, controlled by a gate.
  3. Transistors can be combined in various ways to perform various digital logic functions.
  4. Integrated circuits are fabricated using a re-entrant manufacturing process, layer-by-layer.
  5. Major manufacturing processes include doping, patterning, diffusion, deposition, and etching.
