The Information Age
A Functional Definition:The “Information Age” is characterized by the acquisition, processing,manipulation, storage, and global exchange of information (knowledge).
Q: Why Age?A: Civilization is profoundly defined by an historical “Age”
(technology, but also: culture, commerce, art, politics, socialization, etc.)
Some Defining Features of the Information Age?

A Bit of Trivia …
How Much Information Flow Occurred Electronically Last Year?

And The Answer Is …
There Was Approximately
17,905,340,000,000,000,000,000 bytes(17,905,340 Terabytes = 17.9 Exabytes)
Of Information Moved On Planet Earth!
For Comparison: - the entire print collection of Library of Congress = 10 Terabytes!- a DVD holds 4.7 Gigabytes!- one typewritten page takes 2 kilobytes!

The Information Age
Some Facts:• The Information Age exists ONLY because of the virtues of a particular
class of materials called semiconductors
• Silicon is the most important semiconductor ($200B)

Silicon
Some Facts About Silicon (Si):• Si is a Group IV element, and crystallizes in the diamond structure • Perfect Si crystals can be grown very large (12 inches by 8 feet!)• Si can be made extremely pure (< .000001 ppm impurities!)• Si is very abundant and non-toxic (70% of the earth’s crust are silicates!)• Si oxidizes trivially to form one of nature’s most perfect insulators (SiO2)• Si is a great conductor of heat (better than many metals!)

The Information Age
Some Facts:• The Information Age Exists ONLY because of the virtues of a particular
class of materials called semiconductors
• Silicon is the most important semiconductor ($200B)
• Silicon can be cleverly manipulated to perform many modern miracles
The State-of-the-art in Microelectronics (2007):• 4,000 MHz 64 bit :P (uses 200,000,000 transistors!)• 16Gbit (16,000,000,000) DRAM on a single Si chip
Some Questions You Should Be Asking:How have we accomplished this?How will civilization, and our lives, be changed forever as a result?What are the limits? Where will it end?

Moore’s Law (1965)
Moore’s Law:The defining features of the integrated circuit technology follow an exponential growth pattern over time.
Moral: Computing power and cost exponentially!
Examples: :P speed, logic gates, memory density, lithography, cost, etc.

Redefining Fast & Small
Our Digital World:• A “transistor” is simply a very tiny, very fast on/off switch (“1” or “0”) • In 2006, one transistor is about 0.10 microns (100 nm) wide
The Size of Transistors:• The wavelength of visible light is 0.4 - 0.7 microns.• 4 transistors could fit inside one wavelength of blue light!
The Speed of Transistors:• This 0.10 micron transistor can switch from a logical “1" (on) to a
logical “0" (off) in about 10 picoseconds (0.00000000001 seconds). • For comparison, light (186,000 miles/sec) travels only 3 mm during
the time it takes to switch this transistor from a “1” to a “0”

Where Will It All End?
• Semiconductor Industry Association Projections (ITRS Roadmap)Metric In 2011Transistor Size 0.05 :m (< 100 atoms)Memory Bits / Chip 16,000,000,000 bitsLogic Transistor Count / Chip 100,000,000 devicesNumber of I/O’s 4,800 I/O pinsPower Supply Voltage 0.6 V
What’s on the Horizon?Data Bandwidth:
40Gb/sec electronics + 128 colors = 1,500,000,000,000 bits/sec (1.5Tb/sec) on oneoptical fiber line
Bandgap Engineering of Electronic Devices:Mix different semiconductors together at the atomic level to speed them up (SiGe)
Quantum Effect Devices:Store information on a single electron!
Molecular Electronics:Biologically-inspired computing and the silicon / tissue interface (living machines?)

The Major ECE Sub-Disciplines:
Microsystems: IC device and circuit fabrication, MEMS, IC packaging, nanotechnology …Electronic Design: amplifiers, analog, digital, and RF integrated circuits …Signal Processing: information extraction, data compression, coding, error correction …Communications: wired and wireless data transmission, signal modulation …Control Systems: feedback techniques for process control, motor control, aerodynamics …Electromagnetics: generating and receiving electromagnetic waves, antennas, radar …Power Systems: generation, transmission, and distribution of electrical power …Computer Engineering: architecture, VLSI design, verification and test, CAD …Biomedical Engineering: ECE + biology for health care, nanotechnology, etc …Photonics: generating, transmitting, and receiving optical signals
Moral: ALL sub-disciplines of ECE require microelectronics!
