The chip or integrated circuit to a set of electronic circuits refers to the use of material, semi-conductive (generally silicone along with the amount of controlled impurities) in the size small (usually less than a square centimeter) can be built. These circuits usually include two or three types of electronic devices are: resistance, capacitor and transistor (the most important of them ). Each chip usually contains a number of very large transistor is the use of the technology complex on the inside, a layer of Silicon similar and with a thickness uniform and without cracks injection have been. Nowadays, the chips are in most electronic devices, especially computers in the dimensions widely used process. There chips are indebted for the discovery of human about semiconductors and the rapid developments around them in the middle of the century, the twentieth.
