Summary of Microprocesadores - Historia, Evolución y Fabricación

00:00:00 - 00:10:00

This video discusses the history, evolution, and manufacturing of microprocessors. Microprocessors are small electronic devices that are used in computers and other electronic devices. The manufacturing process of microprocessors starts with a coating of a substrate material on a machine that applies a chemical agent that adheres the microchip to the substrate. Afterwards, the microchips are placed in situ with no light guiding them. A sample of the chain of assembly is taken for quality control, and then the microchips are welded to a metal lid using a high-temperature oven. Next, an adhesive film is applied to the microchips and then the lid, and the microchip is placed on the adhesive film. Finally, a robotic arm removes the four lid covers and places them on the microchips. The microprocessors are then welded to a card board base using a hot-air welding machine. After welding is complete, the microprocessors are washed in water and solvents to remove any remaining adhesives or contaminants. Finally, the microprocessors pass a quality assurance test. The microprocessors are now ready to be installed on a computer.

• 00:00:00 Microprocessors, which revolutionized electronics 50 years ago, are found in almost all electronic devices in people's homes, and are even in cars. The chip in question, silicon, has special properties because it is a semiconductor, meaning it can conduct or block electricity. This property makes silicon the perfect substrate for the millions of tiny transistors needed to build a modern microprocessor. The problem is that as the tiny transistors are so small, the silicon base on which they rest has to be absolutely perfect. It has taken decades to perfect the production process of silicon with a monocrystalline, perfect structure, and begins with silicon polycrystalline which is heated to 1,420 degrees Celsius and sealed in a special oven called a "silicon desert." After being purified, the molten silicon is introduced into a "wire saw" that cuts the silicon into very thin wafers. These wafers are then passed through a series of chemical and X-ray tests to make sure they are pure and perfect before being placed into a "silicon laminator." This machine uses very thin wire to create oblong "silicon sheets" with a thickness of only two thirds of a millimeter and a purity of 99.999%. However, even
• 00:05:00 Microprocessors started out as much larger devices, but as technology has progressed, smaller and smaller processors have been developed. One designer who has had to work with this scale of device is someone named John Bardeen. He is credited with creating the first transistor, which had a size of only one ten thousandth of a millimeter. This tiny particle of dust can cause an electronic malfunction, so before workers in level III production begin work, they must put on the rabbit costume to signify production. This process begins with the manufacture of silicon chips, which are then passed through a series of steps in the manufacturing process. At each step, different chemicals are used to sensitize the silicon, and then ultraviolet light is used to shrink the design onto the chip. After each step, the chip is washed and sanitized in order to avoid any workers from being contaminated. The final step is to place all the components onto the chip in a layer-by-layer fashion, and then the chip is dried. Microprocessors have come a long way since their inception in the early 1950s, and today they are found in almost all personal computers. The designers of these machines start with a small square of silicon, and over time the

Microprocessors are assembled on a manufacturing line in a process that starts with a coating of a substrate material on a machine that applies a chemical agent that adheres the microchip to the substrate.
