Who am I?• Graduated from UK, 1989, BSEE
– Electro-magnetics, EMC, one laser class
– No hard-core semiconductor class
• Masters, Ph.D., Rice University– Laser interaction with semiconductors
– Semiconductor research with Texas Instruments
• Texas Instruments, 1995-2000
• Cypress Semiconductor, 2000-present
• UK, 2000-present
• I was sitting in your seat 15-20 years ago
• I thought I was going to be a laser / EM engineer
8
Why you should care?
• One day you will graduate, then what?
• Do you want to apply your previous class work?
• What are your options for jobs or grad school?– Possibilities you may not have thought of
• EE584 Intro to VLSI may help your career decision
9
But I’ve heard the class is hard…..• EE584 is taught as a segue to the real world
– We use industry-standard tools– Class work is encouraged to be done at Cypress
• Job prospects from recent students:– Cypress has hired 19 (16 full time, 3 co-ops)– TI, Intel, Cisco, Cadence, Silicon Valley start-ups– These are high-paying, cutting-edge companies
• “Hard” classes are relative to your expectations– Your competition: thousands of EE grads each year– Are you going to settle for lower echelon jobs?
• But can I do the work?– Yes, if you like devices, circuits, programming, …
• But I can get a good paying jobs w/o much effort…– Chicken and egg
10
What is expected from an engineer?• Hours:
– 8am 6pm (nominally)– 7am 12am (sometimes)
• Skills:– Typing– Speaking– Reading– Programming (SKILL, Perl, Ruby, Shell, XL, … )– Flexibility (try new things)– Paying attention, energy, enthusiasm– Playing well with others
• List is independent of your specialty
11
What can VLSI do for me?
• Jobs– Industry is cyclical, but drives economy
• Grad school– New technologies to replace Silicon needed
• VLSI can lead you to:– West Coast (OR, CA)
– East Coast (NY, MA, NJ, NC)
– Midwest (IL, MN)
– Southwest (TX, AZ)
– International (India, Ireland, Germany, Denmark, England, Japan, Taiwan, China)
12
What do you learn/use in VLSI?• Physics
• Chemistry
• Software
• Presentations
• Documentation
• What is important in order to get a job
• FALL EE584 VLSI INTRO MWF 9am
• SPRING EE589 ADVANCED VLSI MWF 9am

BACKUP
14
What are possible jobs I could do?• Software
– Web interfaces: financials, data mining– Scripts to automate manual tasks
• Hardware– Production : large volumes (hundreds – millions)– Engineering : small volumes (one, two, ten)
• Writing– Documentation of what you just did– Simple, yet hard to accomplish
• Speaking– Management, communicate effectively– Believable, trustworthy
15
What is a semiconductor?
• Small switch
• Put lots of them together, you get a chip
• Used in– Cell phones
– Computers
– Toasters
– Cars
– Everything ………
16
How much does an engineer get paid?• 2001 IEEE Salary Survey: Median $93k (n=9,700)
– Experience level
– This is not a starting salary
– Typically takes 10 years work experience
– Education level
– Ph.D. = Master + (3 to 5)
– Master = Bachelor + (3 to 5)
