Boser 20EECS105: Introduction to ICs• ICs are enabling component for electronic systems, e.g.– Computers– Cellular telephony– WiFi– Electronic entertainment• IC characteristics are changing exponentially• What’s next?EECS 105: Lecture 1, Introduction © 2004 B. Boser 21EECS 105 Questions• Circuit related• Trend … where are we in 5 years?• Why is scaling improving circuit performance?• What about power?• When is X economically feasible?EECS 105: Lecture 1, Introduction © 2004 B. Boser 22Why Digital Processing?• Digital circuitry:– Cost/function decreases by 29% each year– That’s 30X in 10 years• Analog circuitry:– Cost/function is constant– Dropping supply voltages threaten feasibilityRef: International Technology Roadmap for Semiconductors, http://public.itrs.netEECS 105: Lecture 1, Introduction © 2004 B.

Boser 25Collaboration• Collaboration is encouraged for– Homework– Laboratory (groups of 2)• But:– Submit genuine homework, lab report– No photocopies– No collaboration in exams …EECS 105: Lecture 1, Introduction © 2004 B. Boser 26Challenge of IC Fabrication• No other EE discipline is less forgiving of errors– You can change PLD’s or software in a day– You can build and test a printed circuit board in a week– It takes monthsto tape out and fabricate a chip– Debugging and characterizing a (defective) chip also takes months• State-of-the-art chips are never perfect– But they have to be good enough for someone to buy them– If you want to sell bugs, try a career in software (quote from Eric
