2. Technology Before the Integrated Circuit Pieces of Technology relied on vacuum tubes. These tubes were much larger in size, and in number. Since vacuum tubes were the only option, equipment was a lot more bulky and heavy. In the late 1950s, the Integrated Circuit was created.

3. Beginning It is the size of a human nail. Circuits measured in MICRONS. A MICRON is a millionth of a meter. The diameter is 1/100 the diameter of the human hair. Made of silicon.

4. Steps to Create (1) The wafer is as thin as a sheet of paper. Grow layers on the wafer using photolithography. Use diffusion to cement impurities to the wafer. Metallization is used to create interconnections.

5. Steps to Create (2) Ion implantation is used to create more interconnections that are capable of conducting electricity. Then the wafer is exposed to ultra-violet light to cement all the patterns onto the wafer. Lastly, etching occurs. Etching is the running of electrically charged gas through the grid of connections.Then it is tested for malfunctions.

6. Impact on Society Created in 1958 Makes devices like laptops, computers, PDAs, and cellphones possible. The circuit lets people delve into places that they usually could not, like the inner Earth, and even space.
