Semiconductor devices & basic integrated circuits • What will you learn? – How semiconductor devices work – Voltage amplifier circuits • analysis and design • applications – Digital CMOS circuit fundamentals (Refer to course syllabus for detailed list of topics) EE105 Fall 2011 Course Overview, Slide 5 Instructor: Salahuddin Relation to Other Courses • Prerequisite: – EE40: KVL and KCL, Thevenin and Norton equivalent circuits, impedance, frequency response (Bode plots), semiconductor basics, simple pn-junction diode and MOSFET theory and circuit applications, large-signal vs. small-signal response, analog vs. digital signals. • Relation to other courses: – EE105 is a prerequisite for EE113 (Power Electronics) and EE140 (Linear Integrated Circuits). – EE105 is also helpful (but not required) for EE141 (Introduction to Digital Integrated Circuits). EE105 Fall 2011 Course Overview, Slide 6 Instructor: Salahuddin Class Materials • Textbook: Fundamentals of Microelectronics (1st Edition) by Behzad Razavi, Wiley Press, January 2008 • Lecture notes will be posted on the bspace • Lab assignments (and tutorials) will be posted online at the bspace • Use bspace for all information: inst website may not be updated • This class is available through podcast EE105 Fall 2011 Course Overview, Slide 7 Instructor: Salahuddin Discussion Sections • Students are encouraged to regularly attend a discussion section. • The TAs will review key concepts covered in the lectures, and work through sample problems. EE105 Fall 2011 Course Overview, Slide 8 Instructor: Salahuddin 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. Pick up a computer account form today. (You will need to use it for the Prelab 1 assignment!) EE105 Fall 2011 Course Overview, Slide 9 Instructor: Salahuddin Grading – Homework • due Tuesdays (beginning of class) • late homeworks not accepted 15% – Laboratory assignments • due at beginning of lab session 15% – 2 midterm exams (in class) • closed book 30% – Final exam* • Fri 12/16/2010 from 7-10pm • closed book bring calculator EE105 Fall 2011 40% Course Overview, Slide 10 Letter grades will be assigned based approximately on the following scale: A+: 98-100 A: 88-98 A-: 86-88 B+: 84-86 B: 74-84 B-: 72-74 C+: 70-72 C: 60-70 C-: 58-60 D: 50-60 F: <50 Instructor: Salahuddin 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 EE105 Fall 2011 Course Overview, Slide 11 Instructor: Salahuddin 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.

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… EE105 Fall 2011 Course Overview, Slide 16 Instructor: Salahuddin 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. The first planar IC (actual size: ~1.5mm diameter) EE105 Fall 2011 Course Overview, Slide 17 Instructor: Salahuddin 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. Intel Penryn® Processor “Moore’s Law” still holds today. 300mm Si wafer EE105 Fall 2011 Course Overview, Slide 18 Instructor: Salahuddin The Silicon Revolution • Steady progress in integrated-circuit technology over 40+ years has had dramatic impact on the way people live, work, and play. • The semiconductor industry is approaching $300B/yr in sales: Military 2% Industrial 8% EE105 Fall 2011 Computers 42% Transportation 8% Course Overview, Slide 19 Communications 24% Consumer Electronics 16% Instructor: Salahuddin EECS 105 in the Grand Scheme • Example electronic system: cell phone EE105 Fall 2011 Course Overview, Slide 20 Instructor: Salahuddin
