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.

Top 5 Ways to Avoid an “A” Grade
1. 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
Early History of IC Devices
Lee DeENIAC-The
Forest, 1906
first digital computer
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
 Invention of the point-contact transistor
▪ Walter Brattain, John Bardeen,
and William Shockley, Bell Labs, 1947
Nobel Prize in Physics 1956
– reproducibility was an issue, however
 Invention of the bipolar junction transistor (BJT)
▪ William Shockley, Bell Labs, 1950
– more stable and reliable; easier and cheaper to make

Discrete Electronic Circuits
• In 1954, Texas Instruments produced the first commercial
silicon transistor.
~$2.50 each
• 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 mid1950s, to search for a simpler approach…

The Integrated Circuit (IC)
• An IC consists of interconnected electronic components in a
single piece (“chip”) of semiconductor material.
– In 1958, Jack S. Kilby (Texas
Instruments) showed that it
was possible to fabricate a
simple IC in germanium.
– In 1959, Robert Noyce
(Fairchild Semiconductor)
demonstrated an IC made in
silicon using SiO2 as the
insulator and Al for the
metallic interconnects.

(actual size: ~1.5mm diameter)

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.
– 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.
