What is VLSI? Why do we have to study this subject? Why build integrated Circuit? IC Technology driving the whole innovative devices and systems which effected the way we live. ICs are much smaller. consume less power than discrete component. easier to design and manufacture. more reliable than discrete system. can design more complex system. The growth of electronic industry. Example of VLSI application Electronic system in cars. Digital electronics control VCRs Transaction processing system, ATM Personal computers and Workstations Medical electronic systems. etc…. The advantageous of digital ICs over the discrete components Size much smaller both transistor and wires. leads to smaller parasitic resistances, capacitances and inductances Speed communication within the chips are much faster than between a chips on PCB. High speed of circuits on-chip due to smaller size. The advantageous of digital ICs over the discrete components (cont.) Power Consumption Logic operation within the chip consumes much less power. smaller size -> smaller parasitic capacitances and resistance -> require less power to drive the circuit. Advantages of IC at System Level Smaller Physical Size can make a small electronic appliances. ie. portableTV, handheld cellular telephone… Lower Power Consumption reduce total power consumption on a whole electronic circuit. cheaper power supply which leads to a simpler cabinet for power supply. Less heat, Fan may no longer be necessary. Advantages of IC at System Level (cont.) Reduce Cost Reducing in number of components. Power Supply requirement. Cabinets The cost of building a whole system is reduce eventhough Ics cost more. Integrated Circuit Manufacturing Technology Let us build a system faster, and more complex system Economics In 1960s,Gordon Moore said that the number of transistor would grow exponentially. The number of transistors per chip has doubled about once a year. IC plant is very expensive. $1billion or more. Is it worth to invest in IC business?
