The Driving Force in the Semiconductor Industry
"Moore's Law" is well-known and widely used in the semiconductor industry to describe the advancement in semiconductor device technology. First observed by Intel Corporation co-founder and former chairman Gordon E. Moore in 1965, it predicts that the transistor density on integrated circuits (ICs) increases exponentially, doubling approximately every 18 months with proportionate decreases in cost. This prediction has held true since then and is a driving force of technology advancements worldwide.
To continue to meet Moore's Law, the length and width of a transistor must shrink about 30% every 18-24 months. The ability to pattern smaller circuits depends on the wavelength of the light used in the photolithography process. A shorter wavelength of light can image circuitry with smaller critical dimensions (CDs) and pitch, which in turn allows the transistors to be smaller and transistor density to increase.
