Silicon wafers are actually semiconductor devices that are heavily used in todays electronics. To some, these micro devices may seem dismissible but they really have important uses in technology. Silicon wafers are primarily used in manufacturing computer chips. Every electronic device that you enjoy these days contains these tiny yet very significant wafers.
Generally, silicon is a good conductor of electricity. If you have it altered, not only will it conduct electricity, you can also make good use of it as an effective insulator. Whats amazing about these sophisticated wafers is that manufacturers only use regular beach sand particles as the main ingredient in the manufacturing process. Everyone knows that sand also acts as a lightning conductor, and the same technology is also utilized in both computer and electronic circuit boards.
