Introduction • A top down view of computer usage components: Manufactured practically using Program/App. Your Choice! High Level Language ICS 103 VLSI Assembly Language EE 390 Microprocessor EE 390 Digital Logic Blocks EE 200 Transistors (MOSFETs & BJTs) EE 203

VLSI? • ICs are the basic block of electronic device design. • They contain many transistors on one chip. • Digital devices rely on digital logic. • First half of 20th century ruled by vacuum tubes. • The magical PN junction - 1939 • Transistor – 1947, BJT – 1949, TTL – 1962, • PMOS – 60’s, NMOS – 70’s, • CMOS – 80’s surviving until nowadays.

Evolution • A logic block contains 2+ transistors. • You build your microprocessor using these blocks!

CMOS Inverter

CMOS Inverter: Low Input I

CMOS Inverter: Low Input

CMOS Inverter: High Input 1 I

CMOS Inverter: High Input 1

CMOS NAND Gate

Advantages of CMOS • Very low power consumption. • Rail-to-rail voltage. • Modular design. • Reliable and robust. Choice of the industry! Intel 4004 Intel Pentium 4

One Main Challenge in CMOS • Increasing temperature increases gate leakage current, or the current escaping through the gate oxide.

Conclusion • VLSI is a mature field of electrical and computer engineering that deals with semi-conductor properties to design patterns that form the building blocks to serve digital circuit design purposes. • BiCMOS, ECL, TTL technologies currently used. Each has its own applications for its advantages. • Serious VLSI research, design and cutting-edge manufacturing takes place in extremely sophisticated factories and labs (fabs).
