Unformatted text preview: Principles of VLSI Design Technology CMPE 413 1 UMBC U M B C U N IV E R S I T Y O F M A R Y L A N D B A L T IM ORE COU NTY 1 9 6 6 IC Technology What advantages do ICs have over discrete components? • Size: Sub-micron vs. millimeter/centimeter. • Speed and Power : Smaller size of IC components yields higher speed and lower power consumption due to smaller parasitic resistances, capaci- tances and inductances. Switching between ‘0’ and ‘1’ much faster on chip than between chips. Payoff at the system level: Systems are physically smaller, e.g. cell phones. Lower power consumption ripple effect => less heat => cheaper power supplies => reduced system cost. • Integrated circuit manufacturing is versatile. Simply change the mask to change the design. However,designingthelayout(changingthemasks)isusuallythemost time consuming task in IC design.
