2. Semiconductor Device Physics is
On this Course
Semiconductor Device Physics is
Our EE’s Common Language of How to Speak up for
Semiconductor Devices from the EE Point of View:
- Capture Needed Knowledge from Other non-EE Groups
- Define the Same Terminology
- Develop the Same Concepts
Valid even in the future Nano era.

3. On Semiconductor Device Physics
Our NCTU EE has a good Scientific reputation
in the field of Semiconductors worldwide.
Semiconductors are the Benchmarks of
how a Country like Taiwan has been respected.

14. Ways to Capture Device Physics
Physics: Concepts involved with a device under study
(fundamental laws, logical thinking, etc.)
Model:
A physical Image of the device projected
onto your mind.
(pictures, formulas, etc.)
Modeling:
Modeling of a device is a quantitative measure of
your understanding of the device.
(calculation, data fitting, parameter extraction, etc.)

15. Some Textbooks Suggested1.
Robert Pierret, “Advanced Semiconductor Fundamentals”, Addison-Wesley, 1987.
(Classical; no examples of Q&A) (Purdue) 2.
Richard Anderson and Betty Lise Anderson,
“Fundamental of Semiconductor Devices”, McGraw-Hill, 1st Edition, 2005.
(General; more examples of Q&A) (Ohio) 3.
Chenming C. Hu, “Modern Semiconductor Devices for Integrated Circuits”,
Pearson Education, (Concise; enough examples of Q&A) (Berkeley) 4.
