What is this class all about?

Semiconductor devices & basic integrated circuits

• What will you learn?– How semiconductor devices work– Voltage amplifier circuits

• analysis and design• applications

– Digital CMOS circuit fundamentals

(Refer to course syllabus for detailed list of topics)


Relation to Other Courses• Prerequisite:

– EE40: KVL and KCL, Thevenin and Norton equivalent circuits, impedance, frequency response (Bode plots), semiconductor basics, simple pn-junction diode and MOSFET theory and circuit applications, large-signal vs. small-signal response, analog vs. digital signals.

• Relation to other courses: – EE105 is a prerequisite for EE113 (Power Electronics) and

EE140 (Linear Integrated Circuits). – EE105 is also helpful (but not required) for EE141

(Introduction to Digital Integrated Circuits).


Class Materials• Textbook:

Fundamentals of Microelectronics (1st Edition) by Behzad Razavi, Wiley Press, January 2008

• Lecture notes will be posted on the bspace

• Lab assignments (and tutorials) will be posted online at the bspace

• Use bspace for all information: inst website may not be updated

• This class is available through podcast


Discussion Sections• Students are encouraged to regularly attend a

discussion section.

• The TAs will review key concepts covered in the lectures, and work through sample problems.


Laboratory Sections• Lab sections will begin Wednesday 9/6.

– 353 Cory (no food or drinks!)

• Students must regularly attend a lab section.

• Lab experiments will be done in pairs. Each person should turn in his/her individual assignments.

• Each pre-lab assignment is due at the beginning of the corresponding lab session. Post-lab assignments are due at the beginning of the following lab session.

Pick up a computer account form today.(You will need to use it for the Prelab 1 assignment!)


Grading

– Homework • due Tuesdays (beginning of class) • late homeworks not accepted

– Laboratory assignments• due at beginning of lab session

– 2 midterm exams (in class)• closed book

– Final exam*

Letter grades will be assigned based approximately on the following scale:

A+: 98-100A: 88-98A-: 86-88B+: 84-86

B: 74-84 B-: 72-74

C+: 70-72C: 60-70 C-: 58-60

D: 50-60F: <50


Top 5 Ways to Avoid an “A” Grade1. Skip live lectures

2. Don’t put adequate effort into HW assignments– Do it at the last minute– Rely too much on collaboration

3. Don’t attend discussion sections

4. Don’t turn in the Lab reports

5. Don’t review HW solutions, old/sample exams and solutions


Miscellaneous• Special accommodations:

– Students may request accommodation of religious creed, disabilities, and other special circumstances. Please make an appointment to discuss your request, in advance.

• Academic (dis)honesty– Departmental policy will be strictly followed

• Cheating on an exam will result in an “F” course grade.– Collaboration (not cheating!) is encouraged

• Homework should be done individually.

• Classroom etiquette:– Arrive in class on time! – Bring your own copy of the lecture notes.

Introduction


Lee De Forest, 1906Early History of IC Devices

1940’s: Vacuum-tube era– Vacuum tubes were used for radios, television, telephone equipment, and computers… but they were expensive, bulky, fragile, and energy-hungry

Nobel Prize in Physics 1956

Invention of the bipolar junction transistor (BJT)▪ William Shockley, Bell Labs, 1950

– more stable and reliable; easier and cheaper to make

– reproducibility was an issue, however

Invention of the point-contact transistor▪ Walter Brattain, John Bardeen, and William Shockley, Bell Labs, 1947

ENIAC-The first digital computer


Discrete Electronic Circuits• In 1954, Texas Instruments produced the first commercial

silicon transistor.

• Before the invention of the integrated circuit, electronic equipment was composed of discrete components such as transistors, resistors, and capacitors. These components, often simply called “discretes”, were manufactured separately and were wired or soldered together onto circuit boards. Discretes took up a lot of room and were expensive and cumbersome to assemble, so engineers began, in the mid-1950s, to search for a simpler approach…

~$2.50 each


The Integrated Circuit (IC)• An IC consists of interconnected electronic components in a

single piece (“chip”) of semiconductor material.

The first planar IC(actual size: ~1.5mm diameter)

– In 1959, Robert Noyce (Fairchild Semiconductor) demonstrated an IC made in silicon using SiO2 as the insulator and Al for the metallic interconnects.

– In 1958, Jack S. Kilby (Texas Instruments) showed that it was possible to fabricate a simple IC in germanium.


300mm Si wafer

From a Few, to Billions of Components• By connecting a large number of components, each performing

simple operations, an IC that performs complex tasks can be built. • The degree of integration has increased at an exponential pace over

the past ~40 years.

“Moore’s Law” still holds today.

Intel Penryn® Processor

– The number of devices on a chip doubles every ~2 years, for the same price.


The Silicon Revolution • Steady progress in integrated-circuit technology over 40+ years

has had dramatic impact on the way people live, work, and play.
