I2L: It's getting faster and smaller

Semiconductor manufacturers have embarked on a four-pronged effort to enhance the already impressive advantages of I
²
L. High chip-circuit densities and good switching speeds have been further extended as manufacturers tighten design tolerances, simplify device structures, reduce signal swings, and apply dielectric-isolation techniques. The result is to advance dramatically the capabilities of the first bipolar technology to compete seriously with MOS in its strong suit — large-scale integration.
