ENEE 313 – Introduction to Device Physics Fall 2008 University of Maryland, College Park Sections 0101/0102/0103 Instructor: Dr. Zeynep Dilli, [email protected] Office Hours: TuTh 4:45 pm-5:45 pm Office: AVW 2332 TA: Geunmin (Daniel) Ryu, [email protected] Office Hours: To be announced Office: To be announced Lecture Schedule: TuTh 3:30 pm-4:45 pm (JMP 3201) Recitation Schedule: Section 0101: W......... 2:00 pm- 2:50 pm (EGR 1104) Section 0102: W......... 3:00 pm- 3:50 pm (EGR 1102) Section 0103: Th........... 8:00 am- 8:50 am (EGR 1102) Course Description: This course covers the physics, structure and conduction processes of semiconductors, followed by a detailed study of pn-junction diodes, metal oxide field effect transistors and bipolar junction transistors. Course Objective: This course aims to introduce the student to the physical principles and processes which have made the semiconductor revolution possible, along with an understanding of the operation principles of the basic devices upon which modern electronics is built. By the end of the class, students should be ready to study more in-depth physics, or more advanced devices being developed even now as device technology progresses. Required Text: Solid State Electronic Devices, 6th ed., Ben G Streetman and Sanjay Kumar Banerjee (ISBN: 0-13-149726-X) Optional Texts: At the end of each chapter there is a suggested reading list. Most of these texts listed are available in the library. Class Website: Materials such as announcements, homeworks, homework solutions, quiz questions and solutions will be posted online. The website for the course is at http://www.ece.umd.edu/~dilli/courses/enee313_fall08/ The course website might migrate to the Blackboard system later. The students will be informed of the change if it occurs. Course Policies: Grading: The points available are broken down as follows: Quizzes 10% Homework 14% Midterm 1 23% Midterm 2 23% Final Exam 30% Homework: Partial credit will be granted for incomplete solutions showing work towards the final answer. However, just the answer without any work shown towards it is not acceptable. This policy holds also for quiz and examination grading. Exams: There will be three exams, two midterms and a final exam. (Dates to be announced.) Extra materials to assist exam preparation will be posted on the website ahead of time. There will be a short (~10 min.) quiz given at the start of class of some classes. These will typically test material covered during the previous week and will be announced ahead of time (i.e. no “pop-quizzes”). We will try to have at least ten quizzes throughoutthe semester and the worst two grades for each student will be discarded when taking the final average. This also means that you can miss two quizzes and have those counted as your two worst grades. Recitations: During the discussion section the TA will work through problems and answer questions. Solutions to the previous homework and quiz may be among material covered during discussion. Course Agenda: 1. Crystal Properties Crystal structure of Si 2. Atoms and Electrons Bohr model Introduction to quantum mechanics 3. Energy Bands and Charge carriers in semiconductors Energy bands in solids Charge carriers in semiconductors and carrier concentrations Carriers in fields 4. Excess carriers Luminescence and carrier lifetime Drift and diffusion, built-in fields Recombination and the continuity equation 5. The p-n junction and some of its properties Depletion, fields and potentials Behavior of the p-n junction under applied voltage Depletion capacitance Diffusion capacitance Current flow through the p-n junction The ideal diode equation 6. Metal-Oxide-Semiconductor Field Effect Transistors (MOSFETs) Sub-threshold behavior Thresholds Linear and saturated operation Capacitance Physical structure and scaling laws 7. Bipolar Junction Transistors (BJTs) BJT physics Forward current gain 7. Introduction to Semiconductor Fabrication and Layout Implementing devices on semiconductor wafers Fabrication steps Other Considerations: Students with special needs should contact the instructor individually to make any necessary arrangements. There will be no make-up quizzes given. Make-up examinations must typically be arranged with the instructor ahead of
