Just a 2-bit Adder - Tote Bag



About the Artwork

2-bit Adder highlights the use of gold in chip making. Early chips used gold on any surface that needed to conduct electricity. The base, or header, where this chip is placed is gold. Even the epoxy that attaches the chip to the base has gold in it. The purest of gold are the thin interconnect wires. 1/1000 of an inch in diameter and 99.99% pure gold, they connect the chip to the external leads. This half-adders chip's features can be seen very well. The top silicon layer is dark red in color, and the lines of the silicon layer underneath can also be seen. The blue and purple cloud that surrounds the chip is the gold epoxy. A common misconception is that gold is the best conductor. It's not; copper is. Being so expensive, why is gold used? Well, it's sticky and shiny. Sticky in that it bonds well to silicon and metal. Shiny because it doesn't oxidize and corrode. These are very key properties that allow the chip to communicate to the outside world reliably. The gold in this chip, as in our world, makes things happen.
