| Abstract The different steps in wafer fabrication such as photolithography‚ layer deposition and the machines and equipments used cause organic and inorganic particles to settle on the silicon wafer causing various defects in the semiconductor. Such defects can be minimized through wafer cleaning; RCA standard clean is a method generally used for this purpose. This technical report aims to discuss the chemical process of RCA cleaning and

Pirates of silicon Valley is a story of the growth of the computer Industry. The movie was based in a historical fact‚ did alter things a little bit of dramatic reasons. The movie begins of IBM during the 1980’s‚ the big brother in the computer world that everyone else feared. One of the two characters in the movie is Steve Jobs along with his friend delight in working computers. They eventually form their own company. Apple Computers are begin making computers. At the Apple Steve Jobs was invited

keys are pressed and if the mouse has been moved. It counts numbers and runs programs‚ games and the operating system. Chip production today is based on photolithography. In photolithography a high energy is shone through a mask onto a slice of silicon covered with photosensitive film. The mask describes the parts of the chip and the UV-light will only hit the areas not covered by the mask. When the film is developed‚ the areas hit by the light are removed. Now the chip has unprotected and protected

structure and strength of the material. Silicon based semiconductors have become a major part of our society. Of all of the inventions in the last century the silicon semiconductor is arguably one of the most influential. This component has allowed technology to enhance and expand at an astonishing rate. You will find semiconductors at the core of every microchip as well as almost all transistors. Any object that is computerized depends on these semiconductors. Silicon is the basis of these semiconductors
