Microelectronic Devices and Circuits• What is it?• Why is this important? Course objective• “Moore’s Law”– # xtrs exponential for 40+ years (unique)• IC complexity

– Better, faster, cheaper & higher volume• Xtr cost, processor performance, ADC performance

– Future direction• Technology constraints– Size – why is smaller better?– Power– Interconnects

• Business constraints– IC revenue– GDP

• Course syllabus

EECS105: 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 Questions

• Circuit related• Trend … where are we in 5 years?• Why is scaling improving circuit

performance?• What about power?• When is X economically feasible?

Why 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 feasibility

105 Syllabus

• Devices for circuits• Amplifiers• Small signal model• Biasing• IC technology & layout• Frequency response• Advanced topics

EECS 105: Lecture 1, Introduction © 2004 B. Boser 24

105 Logistics

• Lectures• Discussion• Homework• Labs• Office Hours• Course Participation

EECS 105: Lecture 1, Introduction © 2004 B. Boser 25

Collaboration

• Collaboration is encouraged for– Homework– Laboratory (groups of 2)

• But:– Submit genuine homework, lab report– No photocopies– No collaboration in exams …

Challenge 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 months to 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
