2 Robotic Arm For you, reaching out and picking up an object requires little thought. But for a microprocessor, such actions require lots of precise instructions. Programming a robotic arm to make something like a peanut butter-and-jelly sandwich could take hundreds of instructions. That is why in factories using robotic devices, each device is usually designed and programmed to do just several steps of the manufacturing process over and over again. The item being manufactured goes from one robotic station to the next until it is completed.

3 Fetch, Decode, and Execute Whether you're playing a game, writing a report, or surfing the Web, the microprocessor in a computer processes your data using the same three steps over and over again. It does these three steps at incredible speed—millions of times a second. Here are the three steps and a short explanation of each: Fetch—Microprocessor gets a software instruction from memory telling it what to do with the data. Decode—Microprocessor determines what the instruction means. Execute—Microprocessor performs the instruction.

4 Small Packages O Transistor O A type of switch that contains no moving parts and uses electricity to turn itself on and off. O Micron O A unit of measure that is one millionth of a meter; synonymous with micrometer.

5 How do they make chips so small? O Takes 600 engineers O They map out the each part by the purpose. O It's like building a city by designing every room in every home and building before you even pick up a brick.

6 Recipe For a Microprocessor O What makes up a microprocessor? O Light O Metals (silicon, copper, aluminum ) O Chemicals (boron) O Water O Masks

7 Building Skyscrapers On a Wafer O It takes about 2 months to create a microprocessor. O There are hundreds of microprocessors in 1 silicone wafer. O A microprocessor is made up of many layers, up to 20 different layers, (silicon dioxide, photoresist, etc) through etching and layering the microprocessor’s layers are connected. This allows it to do its many jobs we depend on it doing. O The silicone wafer is made by placing all the microprocessors together.
