Computer chips and the silicon-based transistors inside them are rapidly reduced in size by a factor of 4 every 3 years. According to the Semiconductor Industry Association, it is expected that the size of the circuits in the chips will reach the size of only a few atoms in about 20 years. Since, almost all modern computers are made from silicon semiconductor transistors, patterned and carved by photolithography, the predicted size reduction of the circuits may be not the most economical method for the future. An enormous amount of money has been invested in the semiconductor industry in order to consistently reduce the size and improve semiconductor electronics. Smaller circuits require less energy, operate more quickly and require less space. Currently, ultraviolet light is used to create the silicon circuits with a lateral resolution around 200 nm, which is the wavelength of ultraviolet light. As the size of the circuits reduces below 100 nm, new fabrication methods must be developed.
