Objectives

• This lecture is intended as a review and is
  conducted in a tutorial manner. We try address
  the following questions
• What is semiconductor material?
• What is electrical conduction?
• Why silicon to build an IC?
• What is the atomic structure of silicon?
• What is intrinsic and extrinsic silicon?
• What are the majority and minority carriers?
• What is n material, p material ?
  
• What is Carrier mobility ?
• What is Field Effect?
• What are the processing steps ?
